PREFACE
This Handbook was produced primarily to aid Atlantic Richfield Hanford Company employees whose work involves criticality safety considerations. Use of this book is not intended to replace final analysis of problems by a qualified criticality safety specialist, but it should permit greater freedom in preliminary studies.
The mere existence of a fissile material in quantities greater than a minimum critical mass creates some finite risk that criticality will occur. This risk of criticality can be held to an acceptably low probability by imposing restrictions on the manner in which the fissile material is processed, transported, and stored. This Handbook provides guidance in such areas for the process engineer or designer in the initial steps of equipment and process design or modification prior to review by a criticality safety specialist. In addition, the Handbook combines a number of fissile material handling requirements into a single reference manual and supplements more widely recognized reference works.
Because the increasing amount of experimental data permits (and sometimes demands) periodic revision of criticality parameters and because those of us in criticality safety work sometimes have peculiar ideas about what constitutes an applicable, useful or safe set of data for our own peculiar problems, we have designed the Handbook in a loose-leaf form. Thus, pages can be updated, new material added or sections rearranged to the desire of the user.
Some of the data included here is less conservative than material from TID-7016 and TID-7028, the normally accepted general references on criticality parameters. This is primarily due to a greater amount of available experimental data and to greater confidence in the computer programs presently used in criticality calculations. The computer codes used are generally indicated with each set of data. Those used within the Atlantic Richfield Hanford Company are currently:
UNCLASSIFIED
UNCLASSIFIED iv ARH-6 00
For cross section generation and reactivity calculations
For critical size and reactivity calculations, one and two dimensions
For reactivity calculations of single units and arrays in three dimensions
No attempt has been made initially to generate "safe" parameters. VJherever generated parameters are considered to have a potential for being nonconservative, comparisons with existing experimental data (if any) are shown or referenced, and an attempt is made to indicate the degree to which the data is nonconservative.
The proper use of the enclosed information requires a basic understanding of criticality. Improper use of this information can result in a criticality incident with the possible loss of life and many lost man-hours during recovery.

I.B-1 ARH-600
The management policy of the Atlantic Richfield Hanford Company (AJRHCO) regarding criticality prevention in facilities designed to process,transport,and store fissile materials is defined in a series of policy
operating instructions that delineates ikponsible personnel and the appropriate
authority necessary to assure compliance with the policy. Tlie policy for criticality prevention is that, in all of its activities involving fissionable materials, ARHCO shall exercise control such that the probability of a criticality incident is held at the lowest practical level. Where practicable, the design of manufadjuring and laboratory facilities and equipment handling fissionable materials will include geometric limitations to minimize the probability of a criticality incident. In addition, there will be a criticality prevention system based on written specifications and implemented by written administrative procedures. The specificatz.ons will establish limits so that no single credible ecjuipment failure or human error can cause a criticality incident. The written specifications will define limits in practical and administratively controllable terms. Appropriate personnel training and enforcement assure understanding of the specifications and appropi'iate use of the administrative procedures. Table B.l £;hows the responsibilities and relationships for criticcility control and Figure B.l shows the path for criticcility prevention specification development approval and auditing within ARHCO.

3.1 Materials to be Covered
All fissile materials shall be controlled by specifications unless specifically exempted below. Fissile materials are those nuclides capable of sustaining a nuclear chain reaction. Known fissile nuclides are: ^^^U, ^^U, ^^Np, ^^^Pu, 2^^Pu, - opu, - ipu, - Am, " Am, '' Am, 2'*'*Cm, 2'»7cjn 2I.^cf^ ^^^ 25icf.
The following materials are exempt from need for specifications:
Natural and depleted uranium.
Fifteen grams of " Am or any fissile nuclide with atomic number <95.
Two grams of any fissile nuclide with atomic number 95.
Uranium solutions, compounds and metal, if not latticed, enriched to £1.0 percent ^^^u or its nuclear equivalent.
. ^^^Np, ^^^Pu, "" Am, and '*'*Cm with H/X >5 in any amounts.
3.2 Assumptions
In formulating design and operating limits, the responsible process engineer shall consider all pertinent process conditions and failure possibilities. The worst foreseeable combination of fissile material density, diluent composition and distribution, reflection, interaction, and measurement uncertainty must be assumed. Some conditions may be assumed to be incredible if specifically excluded by technical or design considerations. For example, allowances may be made for neutron absorbers, i.e., nitrogen, boron, uranium-238, etc., that will be associated with the fissile material, provided the presence of the absorber can be satisfactorily assured by technical factors or operational control. The use of the assumed conditions by the criticality specialist in reviewing the problem implies his consideration and acceptance of them.

In the absence of directly applicable experimental measurements, the limits may be based on theo-rei:ical calculations, provided the validity of the calculational method has been proven by co::relation with experimental data. Attempts shall be made to assign limits of error to both ex]3erimental and calculational results.

Th<i keff to be used as peannissible upper limits fo:: the worst foreseeable conditions is defined below for three levels of confidence in the accuracy of the calculated k^ff value:
a. If reliable experimental data exist for closely similar systems and adequate calculational techniques exist for relatively
UNCLASSIFIED
UNCLASSIFIED I.C-4 ARH-60 0
small extrapolation of the data, the kgff of spheres and cylinders shall not exceed 0.98 and the k ^ ^ of slabs shall not exceed 0.97. ^^^
b. If limited experimental data exist for a similar system and relatively large but reasonable extrapolations are necessary, the calculated keff of the system shall not exceed 0.95.
c. If no applicable experimental data are available such that calculations must be based on theory derived from experimental data, the calculated k^ff of the system shall not exceed 0.90.
Increased safety factors should be used in some conditions as noted below.
3.5.1 Probability of Error
Safety factors shall be proportionate to the probability that the specified criticality prevention limits will be exceeded. For example, it is possible to specify the exclusion of water or equipment dimensions with a high degree of confidence. On the other hand, a possible operating error has a finite probability of being committed at some time in the future.
3.5.2 Risk to Personnel
Sizable and multiple safety factors are desirable when personnel are to be located in the proximity of fissile materials; conversely, when a massive shield is interposed between the fissile material and personnel, a somewhat higher risk of criticality can be tolerated. In this context, a massive shield is defined as at least two feet of ordinary concrete or its attenuation

UNCLASSIFIED
UNCLASSIFIED I.C-5 ARH-600
equivalent for the neutrons and gamma rays emitted during a nuclear excursion; the shield and other containment barriers should have sufficient mechanical strength to confine any materials dispersed by the potential reaction.
3.6 Al!LoWance for Emergencies
Re<3ognizing that gross contamination of the en ?'ironment would create a greater cumulative hazard than would be created by nuclear criticality, the specifications may permit actions involving an increased risk of criticality if necessary to protect a facility from incipient loiss of confinement barriers by fire or ex]3losion.
4. SAFETY MECHANISM LIMITS

Assurance. The decision as to which mechanism, ion of mechanisms, is to be used in a
ituation shall represent a balanced judgment, :ring the possibility for failure of each sm, the degree of risk to personnel or pro-continuity, and the cost of implementation.
In spec;Lfying limits on dimensions, concentrations, or masses, all credible conditions must be considered.
4.1 Geometrically Safe Equipment
^ARHCO Oper Prevention
Geometrically safe equipment is subcritical by rtue of neutron leakage under all possible
tions of inventory and reflection. To be geometrically safe" the diameter of a cylinder
be specified as no more than 2.8 inches, B inches, or 1.7 inches for handling uranium-5, uranium-233, or plutonium, respectively;
ijnilarly, the thickness of a slab shall be

specified as no more than 0.5 inch, 0.2 inch, or 0.25 inch, respectively.
These limits are so restrictive that large-scale processing of fissile materials in "safe" equipment would be prohibitively expensive.
4.2 Geometrically Favorable Equipment
Geometrically favorable equipment is subcritical, by virtue of neutron leakage, under the worst foreseeable process conditions. The absence of water flooding or sufficient inventory to sustain a fast neutron reaction may be assumed if these conditions can be maintained with minimal administrative control; such assumptions, if made, must be recorded as a precluded condition in the criticality prevention specification applicable to that facility. The reliance on one dimension of a vessel controlling the reactivity parameters requires that all other dimensions of the vessels either be physically limited by available space or be included in the calculations as infinite dimensions.
The following values are permissible upper limits under the worst foreseeable process conditions, assuming directly applicable criticality data or standards and normal failure potential. If greater uncertainty exists in either the technical basis for the specification or the assurance of control, proportionately greater safety factors as specified in section 3.5 b and c shall be used.
4.2.1 Cylinders
To be "geometrically favorable" the diameter of a cylinder is limited to a maximum value which corresponds to a keff no greater than 0.9 8 or to 95 percent of the critical diameter.
4.2.2 Slabs
To be "geometrically favorable" the thickness (the smallest dimension) of a slab is limited to a value which corresponds to a keff no greater than
UNCLASSIFIED
UNCLASSIFIED I.C-7 ARH-600
0.9 7 or to 90 percent of the critical slab thickness.
4.2.3 Irregular Shapes
For vessels of unspecified or irregular shape, the permitted volume is no more than 75 percent of the minimum volume that would be critical at optimum concentration.
4.3 Fii:ed Poisons
4.4 Nu
Wh^n "fixed poisons" are used to prevent nuclear ticality, the equipment must be so constructed
th^t neutron absorbers in the structure prevent ticality under all foreseeable process condi-
(pns. Fixed poisons are normally used in a sel in such a manner as to permit an increase the size of a critically favorable vessel, allowable fissile mass, the allowable fissile centration, or some combination of the three,
c inspections shall be specified, as ired by the "fixed-poison removal potential
the system," to verify the quantity and loca-^n of the poison in the structure. In no case 11 inspection intervals exceed one year.

lear Blanks
A huclear blank consists of a physically removed secrtion of a process line. Nuclear blanks are used in lines from flushing or utility chemical headers to process equipment when the inadvertent addition of a chemical could cause criticality, su:;h as by precipitation.
4.5 Ad:ninistrative Controls
Wh^n it is not practical to prevent criticality using favorable geometries or fixed poisons, liance must be placed either on limitations mass or concentration, or on the presence of
oluble poisons. The process conditions so controlled by operating personnel shall be
to insure that neutron loss by leakage absorption will prevent criticality even
by r e of s
l i t i i t e d o r
UNCLASSIFIED
UNCLASSIFIED I.C-8 ARH-6 0 0
though any single credible error or omission has been committed. Instruments and/or mechanical devices are provided to assist operating personnel to measure and control the process conditions within prescribed limits.
The following values are permissible upper limits for each mechanism of control, assuming directly applicable criticality data or standards and normal failure potentials. If greater uncertainty exists in either the technical basis for the specification or the assurance of control, proportionately larger safety factors shall be used.
4.5.1 Control by Mass Limits
The quantity of fissile material in a given location is to be limited to an amount less than half that required to sustain a nuclear reaction under any credible conditions of geometry, moderation, and reflection. A double batched condition shall not result in a keff higher than the applicable limit in Section 3.5 under the worst foreseeable conditions.
In continuous processing systems located behind massive shielding, the quantity of fissile material in a vessel is limited to a maximum of 75 percent of the mass required to cause a criticality in that vessel under the worst credible condition; the keff of the system under this condition must be within the appropriate limits of 3.5 above. If the continuous processing system is located in an area normally occupied by personnel, the mass in a vessel is limited to less than 50 percent of the mass required for criticality under the worst credible conditions in that vessel.
4.5.2 Control by Concentration Limits - Solutions
The concentration of fissile material dissolved or dispersed in another medium is to be limited such that neutron absorption in the diluent prevents criticality.
UNCLASSIFIED
I.C-9 ARH-600
The permitted concentration of fissile materials in solution shall not be greater than 50 percent of the minimum critical concentration in that vessel; if the vessel is behind a massive shield, the permitted concentration may be 75 percent of the minimum critical concentration. In neither case shall the keff at the allowable concentration exceed the applicable value listed in 3.5. In addition, there shall be specified for the vessel a mass limit such that the keff of the system shall not exceed the applicable value listed in 3.5 under the worst conditions attainable by the inadvertent concentration of the fissile material, as by precipitation, evaporation, etc.
Control by Concentration Limits - Arrays
The dispersal in space of discrete accumulations of fissile materials is controlled with respect to geometry and distance such that the nuclear reactivity of any single subcritical unit is not significantly increased by the mutual exchange of neutrons (interaction) with adjacent units. For a planar or three-dimensional array, the permitted array shall either have a keff no greater than the applicable value listed in 3.5 for the worst foreseeable conditions or shall be limited in number of units to one-half that calculated to be a critical reflected array. Double batching of a single unit in the array must not exceed the designated keff.
Control by Soluble Poisons
Neutron absorbing materials are to be in solution with the fissile materials in sufficient concentration to prevent criticality under all foreseeable process conditions. If reliance is placed on the presence of a soluble nonprocess neutron
UNCLASSIFIED
UNCLASSIFIED I.C-10 ARH-600
absorber to avoid criticality, the minimum poison concentration shall be specified such that the keff of the system shall not exceed the applicable value listed in 3.5 for the worst foreseeable conditions. The term "worst foreseeable conditions" must include consideration of mechanisms that might change the poison (absorber) concentration, as well as potential changes in fissile atom concentrations.
Soluble poisons shall not be used as the primary means of precluding criticality unless the system is behind a massive shield. Soluble poisons may be used in unshielded systems as a secondary control to be operative in the event that the primary control mechanism is voided.
5. FIRE FIGHTING
In areas containing fissile materials, the requirements of ARHCO Operating Instruction, 1.6.6.3, "Criticality Prevention in Fire Fighting," shall be considered in all criticality prevention requirements. For example, when specific fire fighting systems (such as automatic sprinkler systems or fire fog) are allowed, the system shall be limited by design such that the addition of the fire fighting media will not permit criticality via increased moderation, reflection, dilution, etc.

2. Criticality Prevention Specification
Coincidental with the final hazards review (or slightly before) the criticality prevention specifications are prepared by the responsible department using the technical criteria as a
The acceptance of these specifications by the plant operations manager implies that adequate administrative procedures can be formulated and enforced and that these procedures are auditable. These specifications may be modified at any time,
UNCLASSIFIED

but the modification requires the same signatory approval as the original specification.
Subsequent day-to-day audits by the operational personnel, quarterly audits by Operational Support Engineering and Research and Development personnel, and annual audits by external criticality specialists form a sound basis for criticality control. The reports of these audit groups give a measurement of the adequacy of criticality prevention throughout Atlantic Richfield Hanford Company (ARHCO).
Facilities Change Notice
The operation of any plant requires modification and/or equipment replacements on a day-to-day basis. Hazards control in major projects is handled via scope reviews, criticality prevention specifications, etc., as defined above. A small equipment modification or a series of small modifications, however, could result in a loss of control and could end in a criticality incident. To assure adequate and continuous control of criticality, a facilities change notice is employed to describe any planned physical changes to plant or equipment. The notice once initiated by a responsible person is submitted to the Operations Support Engineering group for review for potential chemical or criticality hazards. When appropriate, nuclear safety experts are requested to review the change. All changes involving equipment handling fissile materials must be reviewed prior to making the physical change.
If the facility change is considered to affect criticality safety adversely, a hazards review is made.

tions
The risk that a criticality could be caused by adding water to chemical processing facilities varies from zero to high, depending on the quantity, form and
of the fissile materials present. For fire ghting purposes, chemical processing facilities have
ivided into four categories, depending upon the ality risks involved, as follows:
Category Probability of Criticality if Water is Added
Zero. The addition of water to the facility cannot cause criticality because the quantities of fissile materials present are too small.
UNCLASSIFIED
UNCLASSIFIED I.F-2 ARH-600
B Minimal. The likelihood of criticality resulting from fighting a fire with water is very small. While fissile materials are normally present in quantities exceeding a minimum critical mass, the fissile materials are in a form, in packaging, or so stored that criticality is practically impossible.
C Finite. Under some foreseeable conditions, the addition of water could cause criticality. This category embraces two types of areas:
1. Those process areas in which fissile materials are normally present in quantities exceeding a minimum critical mass; the fissile materials are normally held in such a manner that the addition of water would not cause criticality.
2. The personnel working areas immediately surrounding Category D facilities.
D High. Fissile materials are normally present in a configuration that could be made critical by the addition of water, or the configuration is very likely to be changed by fire such that the addition of water could cause criticality.
2. Designation of Areas
Each Criticality Prevention Specification has a Fire Fighting Section in which the fire fighting categories assigned to the facilities covered will be specified along with any special fire fighting restrictions or precautions. The assigned categories are subject to change with changing process or equipment. All plant areas not specifically mentioned in Criticality Prevention Specifications are in Category A.
To provide immediate fire fighting guidance, all areas (except Category A) are posted with an appropriate noncombustible sign denoting the fire fighting category for that area. The signs should be mounted 1/8 inch from the surface to which they are attached and positioned in the center of and immediately above the entrance to each categorized area. Usually this will

UNCLASSIFIED
UNCLASSIFIED I.F-4 ARH-600
Category A Areas
No special criticality precautions are taken in fighting fires in Category A areas. Automatic fire fighting systems of any approved type may be installed, and water may be used in any quantity or form.
Category B Areas
No special criticality precautions are taken by fire fighters in Category B areas. Automatic fire fighting systems of any approved type may be installed. While water may be used in any quantity or form, the use of high expansion foam or water fog is preferred over a stream of water to minimize the probability of relocating fissile materials into a critical array. Operating personnel are to be alert to the possibility that fissile materials could be pushed together as a result of the fire or fire fighting efforts (e.g., collapsing structures, gushing water, etc.) thereby significantly increasing the risk of criticality.
Category C Areas
Plans for the use of water to fight fires in Category C areas are incorporated into the Criticality Prevention Specifications applicable to the facility involved and may include dry chemicals, water fog, high expansion foam or automatic sprinkler systems. Automatic fire fighting systems which use limited amounts of water may be recommended. Fire fighters should not direct a solid stream of water at process equipment or floor areas in the vicinity without prior clearance from the attendant building management or in his absence, the senior fire officer.
Fire fighters should be alerted to the possibility that fissile materials in the hoods may have been or may be rearranged from their normal position into a more reactive configuration. If possible, an assessment of the additional risk of criticality should be made, preferably by operational personnel before the fire fighting methods other than those permitted above are used.
Situations which potentially present a hazard include the following:
a. The widespread accumulation of process solution or solids on the floor or in a sump to a depth of two inches or greater;
UNCLASSIFIED
UNCLASSIFIED I.F-5 ARH-600
b. An accumulation of resin or other process solids in a mound more than four inches high;
c. Burning plutonium metal; or
d. Metallic plutonium if it has been deformed or displaced from its normal position.
Category D Areas
Directions for the use of water to fight fires in Category D areas is incorporated into the Criticality Prevention Specifications applicable to the area. Automatic fire fighting systems which use water are not permitted, and the inadvertent drainage of water into these areas is precluded by design. The use of water fog will be acceptable under conditions listed in the Criticality Prevention Specifications. Fire fighters should not use water in any other forms without prior clearance from the attendant building management or, in their absence, the senior fire officer. If the confinement barriers enclosing a Category D area are destroyed during a fire, a prudent decision must be made, after considering the immediate facts, as to what means of fire fighting will be required to minimize injury to personnel, uncontrolled contamination spread and damage to facilities,
4. Responsibilities
The processing, storing or transporting of fissile materials within chemical processing facilities is controlled by Criticality Prevention Specifications. All chemical processing areas containing fissile material are categorized for fire fighting and the category listed in the Criticality Prevention Specification.
In addition, the following specific responsibilities are assigned to each Operations Division Department Manager with respect to those areas under his functional control:
a. Implementing the fire fighting restrictions covered in this Operating Instruction.
b. Posting the facilities under his jurisdiction and keeping the posting current.

G. PACKAGING OF FISSILE MATERIALS AND ON-SITE TRANSPORTATION
Atlantic Richfield Hanford Company (ARHCO) complies with all applicable Department of Transportation and Atomic Energy Commission (AEC) Regulations for packaging radioactive materials for off-site transportation. International shipments will also comply with all applicable IAEA Regulations. Responsibility and accountability for the package and its contents transfers to the AEC at the Company's dock. For on-site shipments the package and method of transportation must also comply with AEC Regulations. Only approved off-site and on-site shipping and storage containers are used. See Sections II.F.3, 4, 5, and 6 for approved containers and allowed array sizes.
1. Fissile materials are those nuclides capable of sustaining a nuclear chain reaction. However, for criticality safety it is not necessary to consider as fissile those fissile nuclides which, under any conceivable conditions, could not possibly be accumulated in sufficient amount, or in the proper form, to exceed a safe mass. Nuclides currently considered fissile are: ^^^U, ^^^U, ^^^Np, ^''Pu, ^^^Pu, ' ''Pu, ^'^^Pu, 2'* Am, " Am, - Am, ^ ' Cm, " Cm, ' '*Cf, and ^^^Cf. Natural and depleted uranium are not considered fissile materials. See DOT Regulations for other exemptions.
2. Fissile radioactive material packages are classified according to the controls needed to provide nuclear criticality safety during transportation as follows:
a. Fissile Class I packages may be transported in unlimited numbers, in any arrangement, and require no nuclear criticality safety array controls during transportation. A transport index is not assigned to Fissile Class I packages for purposes of nuclear criticality safety control. However, the external radiation levels may require assignment of a transport index.
b. Fissile Class II packages may be transported together in any arrangement, but in numbers which do not exceed an aggregate transport index of 50. For purposes of nuclear criticality prevention, the transport index of an individual package shall not be less than 0.1 nor more than 10 and shall be the higher of the two values required by either external radiation levels or criticality prevention. Such shipment requires no nuclear criticality safety control by the shipper or carrier during transportation.
UNCLASSIFIED
UNCLASSIFIED I.G-2 ARH-600
c. Fissile Class III shipments contain packages which do not qualify as Fissile Class I or II packages. Nuclear criticality prevention and radiation control during transportation are provided by special arrangement between the shipper and the carrier.
3. Miminum Critical Mass (MCM) is the smallest amount of fissile material of a specific type, physical form, and enrichment which is capable of sustaining a nuclear chain reaction under optimum conditions.
4. Criticality Safety and criticality prevention are used synonymously; the terms refer to the limits established to prevent nuclear chain reactions in a nonreactor environment.
5. Off-site Shipment is the movement of material from ARHCO facilities to any receiver other than the on-site Hanford contractors listed below:
Atlantic Richfield Hanford Company
Battelle Memorial Institute - Pacific Northwest Laboratory
Douglas United Nuclear
Hanford Environmental Health Foundation
J. A. Jones Construction Company
WADCO
6. International Shipment is the movement of material outside the continental boundaries of the United States.
7. Packager is the manager of the section which prepares or directs the preparation of a package for off-site shipment and transfers the package to AEC-RL for transport.
8. Shipper is the manager of the section which prepares or directs the preparation of a package and delivers it to an on-site Hanford contractor. Off-site shipments are made by the Richland Operations Office of the Atomic Energy Commission.
9. Transport Index means the number placed on a package to designate the degree of control to be exercised by the carrier during transport. The transport index for a package of radioactive material shall be determined by: (1) the highest radiation dose rate, in millirem per hour at three feet from any accessible
UNCLASSIFIED
UNCLASSIFIED I.G-3 ARH-600
external surface of the package; or (2) for Fissile Class II Packages only, the number calculated by dividing the number "50" by the number of similar packages which may be transported together.
10. Packaging, Posting, and Transporting Procedures are prepared for the first shipment of a series of shipments, or for a one-of-a-kind type shipment. Ensuing packaging routinely follows this established procedure until it is modified. The manager of the responsible section must determine, with the aid of supporting engineering groups, that the package posting and transportation meets all the applicable Federal Regulations as well as ARHCO Criticality Prevention Specifications.

INTRODUCTION
The frequent use of the term "buckling" baffles some of our friends in the engineering, metallurgical, and chemical branches of our technology, ]ust as we reactor physicists are often perplexed by metallo-graphic slides or by process stream termmology
The barrier against the understanding of buckling is partly semantic and partly mathematical. The first difficulty arises from our careless use of the same word for two fundamentally different concepts: geometric buckling and material buckling. The second arises from the fact that a concise and elegant treatment of the subject involves the use of differential equations. At the risk of being somewhat long-winded, I am taking an "operational" approach to make the two kinds of buckling plausible without higher mathematics
The reader is presumed to know that the neutrons we are concerned with are set free as a result of nuclear fission inside a reactor, but perish after an erratic journey by being caught m a nucleus, fissionable or not, inside or outcide the reactor.
1. The Multiplication Constant
When a neutron chain reaction continues at a constant rate it is because enough of the neutrons bom in a given number of unrelated fissions* survive competing hazards to give rise to the same number of new fissions. This survival is threatened by two kinds of accidents that may terminate the useful life of a neutron prematurely. One is leakage from the reactor, the other is non-productive absorption within the reactor.
The ratio of fissions in two successive related generations is called k, the multiplication constant. If k IS less than one, the offspring are less numerous than the progenitors and the fission rate declines with time. If k IS greater than one, fissions become more frequent in time and the reactor power increases. Whether a given type of lattice proposed by an engineer will support a chain reaction within an enclosure of his choice (i.e., whether or not k can be >: 1) is a crucial question that must be answered by the physicist before the engineer gets involved in detailed design.
2. Leakage from the Reactor, Geometric Buckling
The answer depends, in part, on the amount of leakage of neutrons from the reactor. If the lattice were infinite, there would be no leakage. Thus, it is convenient to write fe as a product of two terms, the multiplication constant of an infinite lattice of the proposed composition, k^, and the fraction of the neutron offspring that does not leak from the finite lattice. The latter term depends on properties of the lattice and also on the size and shape of the reactor. These dependencies can, in fact, again be split into two separate factors, one of which relates to the lattice only and the other to the geometric shape only. The first has to do with the average distance traveled by a neutron m the lattice from its place of birth to its place of death. Only neutrons that are bom near the surface can escape from the reactor. Conversely, neutrons that are born at a distance inside the surface of the reactor that IS substantially greater than the average traveling, or "migration" distance withm the lattice will not get to the surface and, hence, will not leak out. Actually, the first factor in the leakage term turns out to be the average square of the distance traveled by the neutrons during their life within the lattice, and is called the migration area, M^. The greater M', the greater is the depth from which neutrons can leak and therefore the greater is the total leakage from the reactor.
*For example, in all fissions occurring withm a given time interval that is short compared to the lifetime of a neutron in the reactor.

The second facto rente ring into the non-leakage term is related to the size and shape of the reactor, only. It is possible to combine all pertinent information on size and shape in a single expression. This turns out to vary inversely as the second power of the characteristic dimensions of the reactor. It is called the geometric buckling, Bg'. Formulae for the geometric buckling of the simplest shapes are as follows:

Sphere
Bg'

a, b, c = edges
h = height; r = radius
R = radius
In principle, a B^ ^ can be determined for any size or shape. It is a purely geometric procedure. The geometric buckling may be expressed in units of cm" ' . In practice, this unit is too large, and smaller units are used. Some people use m" (= 10"*cm"'), others use 10"*cm"', ihe microbuck.
It can be shown that the product of the two factors, Af' and Bf', represents the number of neutrons that leak from the reactor for each neutron that dies within the reactor. Hence, the fraction of all lost neutrons that are lost through leakage is
ITWB^ and the fraction of neutrons that do not leak is

The multiplication constant can now be written in the form
Once the lattice and reactor size and shape are chosen, the crucial question, whether or not k can be a 1, is thus reduced to the determination of M' and ^00, both of which are properties of the (infinite) lattice. M ' can be calculated or measured, more or less directly. However, the evaluation of k^, involves a number of separate steps. These steps will be discussed in the following section. After reading that section, the reader may wish that the determination of A/' and of all the quantities entering * „ be simplified and replaced by a single concept and measurement. This wish will be fulfilled when we get to the section on Material Buckling.
3. Survival Inside the Reactor
Not all of the neutrons that escape lealcage from the reactor contribute to the chain reaction by causing fission. Many are captured in the non-fissionable nuclei that make up the structural material, the moderator and other substances present. Even when a neutron is captured in a fissionable nucleus, there is a fair chance that this nucleus will not undergo fission. In that case, a neutron is withdrawn from the chain reaction by the fuel itself.
The average number of neutrons created in a fission event is designated by v, {= 2.43 for U" ' ) . To arrive at a value of k„ for a proposed lattice, this number v must be multiplied by the probability that a neutron will escape capture by a non-fissionable nucleus and by the probability that a fissionable nucleus, having captured the neutron, will undergo fission. The latter probability is usually written as
1 1 + a
where a is the probability ratio, capture to fission, in the fissionable nucleus.
Thus, *«, = vx (capture escape probability) x j — — .
Since both v and a are nuclear properties of the fuel and not directly properties of the lattice, they are often represented by a common symbol, the neutron reproduction factor:
In lattices that contain no U ' " or other resonance absorbers, and in which the fuel is fully enriched uranium, there is, in general, no appreciable capture until

U;M CLASSIFIED
the neutrons have been slowed down from their initial kinetic energy of some MeV to the " thermal" kinetic energies of the lattice nuclei, the average of which is about 0.025 eV. In this case, the capture-escape probability is therefore simply the fraction of thermal neutrons that become available to the fuelor the "thermal utilization" f. For each thermal neutron, (1-/) neutron is absorbed by nuclei other than the fuel, and / is absorbed by the fuel. Thus, in fully enriched lattices, *oo = vf-
The reactor physicist looks up rj in a book supplied by the "pu re" nuclear physicist and calculates or measures / , by considering the concentrations and the appetites for neutrons (cross sections) of the various nuclei in the proposed lattice.
If the lattice contains appreciable amounts of U ' " , the story of neutron survival becomes complicated by two effects. A fast virgin neutron can produce a fission in the "non-fissionable" U" ' .^ This results in a dividend of extra neutrons. The calculation of this dividend is complex and depends on the proximity of the nucleus that undergoes fission to the U ' " target and to the moderator. To avoid writing a complicated formula, this "fast fission effect" is usually accounted for by a factor t introduced into the expression for kx-^
Even more involved is the other complication introduced by U " ' . This nucleus captures appreciable numbers of neutrons having a kinetic energy intermediate between that possessed by a neutron in the fleeting moment of its virginity and that shared by the neutron with the surrounding matter during its " thermal" life. If the neutrons have a reasonable chance of interacting with U ' " before they are fully slowed down through collisions with the moderator, there is a substantial chance of their capture in the "resonances" of U " ' . This chance is designated by ( l - p ) ; and p is called "resonance escape probability".
A total description of the neutron life cycle in an infinite lattice containing U'^' can now be given as follows: A fission produces f neutrons, these are increased by the factor e via fast fissions in U " ' , reduced before thermalization by the factor p through resonance capture in U"", reduced after thermalization by the factor / through competing thermal capture in non-fissionable nuclei, and reduced by competing thermal capture in the fuel by the factor 1/(1 + a).
tTo cause fission in IJ a neutron must have kinetic energies above 1 MeV. The term "fissionable" is commonly applied only to nuclides that can be made to undergo fission with thermal neutrons.
t(€-l) is the dividend rate accruing from fast fission.

This is the famous "four-factor" formula for *«,. The thermal capture in the non-fissionable V"' is sometimes included in v rather than in / . Thus, the rj used for natural uranium metal is usually not that of U ' " but a synthetic quantity that involves, besides the ratio of capture to fission in u'^ ' the ratio of capture in 99.3% U*' to fission in 0.7% U'^'.

To answer our crucial question, the reactor physicist must evaluate, calculate or measure the geometric buckling, the migration area M', the neutron reproduction factor 77, the fast fission factor e, the thermal utilization / , and the resonance escape probability p. Actually, things are even more involved than described here. For example, the distribution in energy of the neutrons, the neutron spectrum, affects the nuclear parameters that enter into 77.

It appears that each new lattice requires a considerable number of calculations and/or measurements. However, if there existed a single quantity that combined M ' , 7), t , p and / , in such a way that the crucial question could be answered quickly and directly, only a single measurement might be needed. Fortunately, there is such a quantity. It is the "material buckling".
4. Material Buckling
Let us consider the case in which a reactor is precisely critical. In that case, the pile dimensions (Bg^) are such that the particular combination of Bg' and of the lattice parameters 77, e, p, f, and M', that is shown in equation (3) malces ^ = 1. In that case, and only then
1 + M ' B / Vtpf.
We may generalize this relation by introducing a new concept, the "material buckling" Bm ' such that the equation
l^M'B^ Vtpf
holds, no matter what k is. Thus, B„, shorthand for

M' "
S„ ' happens to be equal to Bg' when * = 1, but, in general, it need not be.
By introducing this shorthand into equation (3) we may now write the generally valid equation
T+WBP'
Our crucial question whether * is greater or equal to 1 can now be replaced by the equivalent question whether B„' is greater or equal to Bg'. If Bm' is greater than Bg', k is greater than 1; if B„' = Bg', k=X, if B„' is less than Bg', k is less than 1.
This problem may be compared with the problem of fitting a lady customer If the dress (geometric buckling) fits the lady (material buckling) the situation is critical for the husband's pocketbook. If the lady is too small for the dress, the matter is inconsequential. If she IS too big, the experiment may result in an accident.
5. The Measurement of Material Buckling
We have seen that Bm ', the material buckling, is a certain combination of properties of the infinite lattice, while Bg', the geometric buckling, is a property of the surface enclosing the finite lattice The concept of the material buckling is attractive because it reduces the criticality question to a simple comparison of Bm ' and Bg', quantities that are different in concept but are similar m their physical dimensions (length " ') and can be expressed in the same units.
Material buckling is directly measurable, thereby obviating separate determinations of M' and of the factors entering ^oo. Of course, a more detailed knowledge of reactor performance requires a variety of information beyond the question of initial criticality. Problems of reactor stability, reactivity lifetime, and productivity depend on other combinations of the lattice parameters discussed above, and on still other parameters. The reactor physicist measures, or calculates, many things besides buckling.
Buckling measurements are made according to two principal methods, m critical or in exponential facilities.
ARH—00
PAGE I I . B . l - ' l
In the "cr i t ica l" experiments, k is very precisely made equal to unity, by equating the unknown material buckling and the geometric buclding In critical experiments with liquid moderator it is possible to achieve this equality by varying the geometric buckling through adjustment of the liquid level. In situations where the geometric buclding is fixed, the equality is achieved by modifications of the material buclding of the unknown lattice. This can be done by changing, by known amounts, some or several of the reactor parameters that enter into Bm ' (see equation 4). For example, / (and M') may be adjusted by the addition to the reactor, or removal from the reactor, of poisons that compete for neutrons with the fuel, e.g., by means of control rods In more sophisticated experiments, a sample of the unknown lattice is inserted into a host lattice of known material buckling, and the reactor is adjusted to criticality The material buckling of the unknown can then be found by solving a set of equations.
In the "exponential" experiments, it is possible to determine material buclding in a subcritical sample of the lattice and therefore without recourse to geometric buckling Since this sample cannot maintain a chain reaction, neutrons must be fed into the lattice. The most common arrangement is a cylindrical sample supplied by neutron sources arranged across the bottom surface. (However, Fermi 's original exponentials were parallelepipeds.) In such an arrangement, one measures the distribution of neutrons throughout the lattice. The rates at which the neutron population decreases as one proceeds away from the source, and as one approaches the surfaces of the lattice, determine a unique value of B„ '. In the conventional vertical tank, it IS usually sufficient to measure the radial neutron distribution at one or two levels and the vertical neutron distribution at one or two radii. A plot of neutron density along a vertical axis may be fitted by exponential functions, hence the term "exponential" facility.
Once the material buckling is known, the critical size of the lattice can be derived for any desired shape. This IS particularly helpful in problems of nuclear safety in connection witli the storage and handling of many fuel pieces. For example, cylindrical fuel slugs could be arranged in many different ways: like bamboo sticks, like soldiers on the drilling ground, or in pyramids like the cans in some grocery stores. From a single material-bucklmg measurement in an exponential, the critical sizes of any of these configurations can be evaluated, whereas the corresponding critical measurements would require assemblies m each of these configurations.
6. Semantics of Buclding
My dictionary defines the noun "buckle" as " a distortion, as a bulge, bend, kink, or twist m a beam. . .", all of which sounds akin to the problem of fitting the lady customer.
Actually, buclding is related to an eigenvalue problem. The second-order differential equation that maps out the shape of a string or of a membrane in an operating musical instrument involves the local inertia (mass density) and tension of the string or membrane. Solutions are subject to the condition that the ends of the string or the edge of the membrane are in a fixed

UNCLASSIFIED I I .B.1-5 AEH-600
position. A similar differential equation aescribes lue neutron density distribution in an operating reactor and involves local lattice properties in a combination called "buckling", as exemplified by our equation (4) defining B„^. The solutions are subject to the condition that the flux must approach zero along the boundary of the reactor. This is true only if the average buckling assumes certain values (the eigenvalues) which involve the information entering into our Bg^.
If the buckling is zero somewhere in an operating reactor, the flux distribution is "flat" in this region, that is, the flux changes with constant slope, for example with zero slope. Where the buckling is positive, the flux shape displays curvature and may have a peak, where the buckling is negative there may be a flux depression. So here is some analogy with the "distortions or bulges" in the vibrating string or membrane.
To some of our colleagues, the word buckling is repulsive. They prefer to talk about "the Laplacian", which is not a fortunate choice as it confuses the concepts of differential operator and of eigenvalue.
It was Professor J. A. Wheeler who introduced the term "buckling" into reactor physics. In geometro-dynamics, a branch of physics, in which Wheeler is a leading pioneer, the material world is reduced to geometry.

Safety Factors
As stated in the ARHCO Technical Criteria for the Prevention of Criticality, page I.C-3-5.> safety factors must be included in all limits and the three degrees of safety factor specified are based upon the confidence in calcinations and the risks involved. A common method of applying safety factors is the use of fractional critical dimensions, volumes or masses. The advantage of using fractional critical dimensions is the ease of application using readily available critical dimension data. While these values are satisfactory in most cases, large systems thus specified may have an effective multiplication constant (kg^f) very close to one, the critical condition. In these cases effective protection will not be attained. On the other hand, the fraction of critical dimension method may be overly restrictive for smaller systems.
A safety factor based on the kgff of a system provides a more consistent overall protection. However, this method of applying the safety factor must be used with caution when dealing with small critical systems where small changes in critical dimensions may result in large changes in kgff. Unless the keff safety factor is less than that normally required for larger systems, the resulting minute dimensional safety factor may be beyond the control of equipment fabricators.
The criticality prevention specialist must consider the limitations on the use of either method in applying safety factors to critical limits. Both kgff limits and dimension limits are specified in the ARHCO criteria, page I.C-6.4.2.
In the following figures the kg^f of fractional critical slabs, cylinders, masses and volumes are indicated for both reflected and bare systems using plutonium-water solution densities. These figures are used only to Illustrate the variation one can find. Other fissile systems could be more restrictive.
The first part of the calculations for the figure was done with the HFN diffusion theory code at .01, .02, .03, .07, .15, .3, .6, and 1.0 grams of Plutonium per cubic centimeter. Although this code is knowQ to be accurate for thermal systems it becomes non-conservative at high concentrations. Therefore, the DTFk transport theory code was used to obtain k-effective values for the faster systems over a range (including stiffi-clent overlap to permit a smooth curve to be drawn) of .07, .15^ '6, 1, 2, 5, J, 10, 15 and I9.6 grams of plutonium per cubic centimeter. The indicated critical reflected slab thickness for plutonium metal may be somewhat large as a result of poor flux matching between core and reflector. However, for our pxirposes the indicated change in k-effective should be satisfactory.

The bucliling equation for a right elliptic cylinder is of the form:
B,.= = B/ + B / = (TT/L)^ + Be (m,M)
where L is the cylinder height, m is tlie semi-minor a::is and M is the semi-major axis (extrapolated dimensions).
The solution of elliptical bucl0.ing, Bg^, takes the form:
Bg^ = K(c2)/mS where c = J^m and K(c^) is a function which varies vrith c
Values of K(c^) can be determined from the accompanying table. Interpolation between points can be determined by the approximate formiola:
K(c=') = K(c/)(c//cS)(c-c^«)/c/-c^r
+ K(c,S)(e^Vc")[l - (c«-c,^)/(c/-c^3)]

ANNULAR INFINITE CYLINDER
Void Core
An annular cylinder whose inner radius, ro, and extrapolated annulus thick.ness, t, is kjiown and which has a void in the center will have a geometrical buckling that is a function of ro^ t and the outer extrapolation distance,^. The graph on page II.B.2-5 shows the relation. If A r = t +X., the value of Ar/rQ will give a value for "V/Bp. rQ. Dividing this by rg and squaring will give the geometrical buckling of the' system. Conversely, if the desired buckling is kno-vm, the inside radius or the annulus thickness can be found.
Isolating Core
Calculations have been made for the relationship between BP, VQ andAr for the annular cylinder which has its core filled with material which effectively eliminates interaction of the annulus across tlie core. However, since small cores are seldori isolating and since for large cores the annul os may be treated as a slab, the relationship will not be reproduced here.

II.E. REFLECTOR SAVINGS AND EXTRAPOLATION DISTANCES
The reflector savings is the amount by which a reflector red-aces the critical size of a system from the bare critical size. It can also be defined as the difference between the reflected extra-polation distance and the unreflected extrapolation distance. 'VJhereas, the absolute value of the extrapolation distance is somewhat difficult to obtain experimentally, the reflector savings can be obtained more easily.
The folloaring data is mainly derived from experiment; calculated values are sho\m by broken lines or otherwise specified.
