IEEE Standards documents are developed within the Technical Com- mittees of the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Board. Members of the committees serve volun- tarily and without compensation. They are not necessarily members of the Institute. The standards developed within IEEE represent a consensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE which have expressed an interest in participating in the development of the standard.

Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed a t the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review a t least once every five years for revision or reaffirmation. When a doc- ument is more than five years old, and has not been reaffirmed, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard.

Comments for revision of IEEE Standards are welcome from any in- terested party, regardless of membership affiliation with IEEE. Sugges- tions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments.

Interpretations: Occasionally questions may arise regarding the mean- ing of portions of standards as they relate to specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason IEEE and the members of its technical committees are not able to provide an instant response to interpretation requests except in those cases where the matter has previously received formal consideration.

Comments on standards and requests for ixiterpretations should be ad- dressed to:

Foreword

(This Foreword is not a part of ANSIIIEEE Std 6281987, IEEE Standard Criteria for the Design, Installation, and Qualification of Raceway Systems for Class 1E Circuits for Nuclear Power Generating Stations.)

This standard sets forth the minimum requirements and guidelines in the design and installation of raceway systems for Cl& 1E circuits and describes acceptable means that can be used to dem- onstrate that such raceway systems are properly qualified. Although this standard asserts that raceway systems are not Class lE, it stipulates that raceway systems, including supports, are designed as seismic Category I. The supports are considered to be a structure type whose function is to restrain and provide structural stability to raceways. Guidance with respect to Class 1E cable systems may be obtained by referring to ANSI / IEEE SM 690-1984, IEEE Standard for the Design and Installation of Cable Systems for Class 1E Circuits in Nuclear Power Generating Stations.

The IEEE will maintain this standard current with the state of the technology. Comments on this standard as well as suggestions for additional material that should be included

in future revisions are solicited. These should be addressed to:

Secretary IEEE Standards Board Institute of Electrical and Electronics Engineers, Inc 345 East 47th Street New York, NY 10017

An American National Standard IEEE Standard Criteria for the Design,

Installation, and Qualification of Raceway Systems for Class 1E Circuits for

Nuclear Power Generating Stations

1. Scope

This standard contains the requirements for the design, installation, and qualification of raceway systems for Class 1E circuits external to electric equipment and components for nu- clear power generating stations. Since aging and radiation have no known detrimental effects upon metallic raceway systems, and since non- metallic raceway systems are limited to under- ground or embedded applications, these two environmental conditions are not considered in this document. The embedments or structural members to which a support is attached are be- yond the scope of this document.

2. Purpose

The purpose of this standard is to provide cri- teria for the minimum requirements in the se- lection, design, installation, and qualification of raceway systems for Class 1E circuits for nuclear power generating stations. It also prescribes methods for the structural qualification of race- way systems for Class 1E circuits.

3. Definitions

The following definitions apply specifically to the subject matter of this document.

accessories (raceway). Devices that are used to supplement the functions of raceway systems. These include such items as dropouts, covers, conduit adapters, fastening devices (items such as conduit clamps, support connections, and ca- ble tray cover clamps), adjustable connectors, and dividers.

anchorage (raceway). The connection between the building structure and the raceway support.

cable tray. A prefabricated metal raceway with or without covers consisting of side rails and bottom support sections. Bottom support sec- tions may be ladder, trough, or solid.

cable tray system. An assembly of metallic ca- ble tray sections, fittings, supports, anchorages, and accessories that form a structural system to support wire and cables.

combination support. A support that serves either raceways of different types or raceway(s) and other mechanical or electric systems such as heating, ventilating, and air-conditioning (HVAC)' ducts, piping, and lighting fixtures.

conduit system. Any assembly of conduit sec- tions, fittings, supports, anchorages, and acces- sories that form a structural system to support wire and cable.

failure (raceway). The termination of the abil- ity of the raceway system to perform its function. The level of damage done to the raceway system is such that either collapse is imminent or an electrical circuit is interrupted or degraded to an unacceptable level, or both.

fittings (raceway). Raceway sections that are joined to other raceway sections for the purpose of coupling together or changing the size or di- rection of the raceway system. These include such items as couplings, elbows, tees, wyes, pull- ing sleeves, and pull boxes.

For convenience and quick reference, Appendix A con- tains an alphabetical listing of abbreviations and acronyms used in this document.

The raceway system shall be designed to per- form its functions and shall not damage adjacent safety-related systems below an acceptable level during and after experiencing all conditions pos- tulated to occur in its environment. As a mini- mum, the design shall adhere to the basic requirements of this standard and ANSI/IEEE Std 384-1981 [ll]'. For additional information, see Appendix B.

In the design and installation of raceway sys- tems, consideration shall be given to the relative structural integrity of aluminum versus steel when subjected to heat from postulated fires and the effects that dripping molten aluminum may have in propagating and spreading fire.

Clearances with respect to other systems shall be established and provided to ensure that move- ment due to loads and load combinations (see 5.10.1) will not affect the integrity of the race- way system.

Raceways shall not be located close to heat sources unless cables are selected or derated for the highest expected ambient temperature. Lon- gitudinal expansion of raceways shall be consid- ered in areas with varying temperatures.

Relative displacement of the raceway system to other systems, equipment, or structures shall be considered in the design of raceway systems. The raceway supports shall be designed to ac- commodate differential settlement and deflec- tions between structures.

Firestops shall be installed in raceways that penetrate a fire barrier. Firestops shall be qual- ified in accordance with ANSI/IEEE Std 634- 1978 [12] or otherwise tested to ensure that the integrity of the barrier is maintained. For ad- ditional fire considerations, see ANSI/IEEE Std 690-1984 [13].

For additional guidelines pertaining to race- way systems, see Appendix C.

5.8 Metallic Raceway System Finishes 5.8.1 General. Metallic raceway systems man-

ufactured from steel will oxidize when egposed to air. This oxidation process could ultimately cause failure. To minimize this possibility, a fin- ish shall be applied to the surface of raceway systems such as galvanizing or plating in ac- cordance with 5.8.2.1 and 5.8.2.2, respectively. See 5.6 for additional coating requirements that may be needed due to the environmental con- ditions in the area of installation.

5.8.2 Manufacturer-Applied Finishes 5.8.2.1 Galvanizing. When a galvanized fin-

ish is specified, one of the following standards shall be invoked:

Prior to fabrication: ASTM A 525-1986 [24], Coating Class G90.

After fabrication: ASTM A 123-1984 [22]. 5.8.2.2 Plating. When a plated finish is spec-

ified, one of the following standards shall be invoked:

Zinc plating: ASTM B 633-1985 [25], Coating Class FE/ZN5.

Cadmium plating: ASTM A 165-1980 [23], Coating Class TS.

5.8.3 Field-Applied Finishes. Field-applied finishes shall be compatible with the finishes applied during the manufacturing process.

5.9 Raceway System Requirements 5.9.1 General. Raceways entering enclosures

from the top or sides shall be designed to min- imize the entrance of condensation or water and to prevent its accumulation within the equip ment. The necessity for equipment drains or con-

QUALIFICATION OF RACEWAY SYSTEMS FOR CLASS 1E CIRCUITS FOR NPGS ANSI / IEEE SM 628-1987

duit seals shall be predicated upon the required environmental parameters of the equipment contained in the enclosure. See ANSI/IEEE Std 690-1984 [13] for raceway fill requirements. Raceways shall not be connected to electrical equipment unless accounted for in the design.

5.9.2 Conduit System Requirements 5.9.2.1 Conduit systems shall be designed

and arranged with suitable pull points (such as boxes and manholes) and bend radii so that the allowable cable pulling tensions and sidewall pressures recommended by cable manufacturers or determined by calculations are not exceeded. See ANSI/IEEE Std 690-1984 [13].

5.9.2.2 Conduit shall be sized to avoid crit- ical jamming ratio diameters. See ANSIIIEEE Std 690-1984 [13].

5.9.2.3 Unless justification is otherwise pro- vided, RMC or IMC shall be used in exposed conduit systems designed for seismic loading.

5.9.2.4 Where compliance is required by lo- cal, state, or federal laws, ANSI/NFPA 70-1987 [19] shall be used in selecting conduit types for use in hazardous locations.

5.9.2.5 The length and installed configura- tion of flexible metal conduit shall be designed to provide for dynamic and thermal movement and to accommodate the largest minimum bend- ing radius of the cables to be installed. The length of flexible metal conduit shall be ac- counted for in the design and qualification of the conduit system. Flexible entry shall be used for conduit entering Class 1E equipment where relative movement between the conduit and the equipment is anticipated.

5.9.2.6 Welding of conduits shall not be per- mitted.

5.9.2.7 The entire metallic conduit system, whether embedded or exposed, shall be electri- cally continuous and grounded in accordance with IEEE Std 665-1987 [26]. Where used as the equipment grounding conductor, flexible con- duit and associated fittings shall be suitable for the anticipated ground fault current; or they shall be paralleled with a ground cable of suit- able size.

5.9.2.8 Embedded conduit may be either me- tallic or nonmetallic. When embedded in build- ing walls or floors, it shall meet the requirements of ANSI/ACI 349-80 [4], unless jus- tification is otherwise provided. Embedded con- duit subject to flooding shall slope to either boxes, handholes, or manholes for drainage or be sealed to exclude the entry of water. Where

embedded conduit crosses a seismic, vibration, or expansion/contraction joint, a piece of flexi- ble conduit or suitable fitting shall be installed to allow relative movement of the structures without damaging the conduit.

5.9.3 Cable Tray System Requirements 5.9.3.1 Cable trays shall be designed to carry

their design dead load (see 5.10.1.1.1) and a min- imum concentrated load of 200 lb at midspan at the centerline of the tray or on either side rail. Under this condition, the tray shall neither fail nor be permanently distorted.

5.9.3.2 Protection shall be provided on ex- posed vertical tray risers at floor levels and other locations where there is likelihood of phys- ical damage to cables.

5.9.3.3 Cable trays shall not be utilized to carry ducts, piping, instrument tubing, or other equipment unless it can be demonstrated that the Class 1E functions of the cables will not be degraded below an acceptable level.

5.9.3.4 Cable tray systems shall be electri- cally continuous and solidly grounded. Where the tray is not capable of serving as an adequate ground return path, a ground conductor of suit- able size shall be attached to and run parallel with the tray.

5.9.3.5 Unless accounted for in the design, conduits shall not be connected to trays. Where continuity of metallic shielding or protection of conductors is required, a flexible connection shall be used to accommodate horizontal and vertical movement caused by a dynamic load.

5.9.4 Wireway System Requirements 5.9.4.1 Wireways shall be permitted only for

exposed work. Wireways shall not be installed in any hazardous location or where subjected to severe physical damage or corrosive vapor.

5.9.4.2 Wireways shall be securely attached to the supports. Adjoining wireway sections shall'be securely fastened together to provide a rigid joint. Vertical runs shall have no more than one joint between supports.

5.9.4.3 Wireways shall be permitted to pass through walls and floors if the pass-through is in unbroken lengths.

5.9.4.4 Extension from wireways shall be made with rigid or flexible metal conduit, in- termediate metal conduit, or trays, where com- pliance with ANSI/NFPA 70-1987 [19] is required by local, state, or federal laws. Dead ends of wireways shall be closed.

5.9.4.5 Wireways shall be electrically con- tinuous and solidly grounded. Where the wire-

11

ANSI / IEEE SM 628-1987 IEEE STANDARD CRITERIA FOR THE DESIGN, INSTALLATION, AND

way is not capable of serving as an adequate ground return path, a ground conductor of suit- able size shall be attached to and run parallel to the wireway.

5.9.5 Underground Duct System Require- menta

5.9.5.1 Duct banks entering buildings, man- holes, or handholes shall allow for relative dis- placement between the structure and the duct bank.

5.9.5.2 The duct bank shall be sloped to drainage points, manholes, or handholes. All en- cased duct joints shall be concrete tight.

5.9.5.3 The duct bank length and configu- ration between pull points (manholes or hand- holes) shall not cause cable sidewall pressures, cable bending radii, and cable pulling tensions that exceed specified requirements (see ANSI/ IEEE Std 690-1984 [13]). Cable pull points shall have openings sufficiently sized to accommodate the cable’s minimum bending radius during in- stallation.

5.9.5.4 The spacing of ducts shall be based on thermal considerations (cable 12R losses, cir- culating currents, etcetera) and to ensure ade- quate concrete encasement. Duct spacer materials shall be compatible with the duct ma- terial. The duct spacer type and longitudinal spacing shall be chosen to prevent excessive de- flection, shall not deform the duct wall, and shall be staggered to avoid shear planes. The bottom spacer shall provide sufficient clearance from the trench floor to permit the specified concrete layer thickness. Wood shall not be used for duct spacers.

5.9.5.5 Metallic ducts shall be electrically continuous throughout and grounded at each ac- cess point.

5.9.5.6 A ground wire of suitable size shall be run along with nonmetallic duct banks. It shall enter every manhole and handhole. The ground wire shall be connected to the station ground system at each end of the duct banks.

5.9.5.7 To avoid damage due to circulating currents, nonmetallic ducts in a bank shall not be looped by ferrous materials (such as rebar or iron mesh) unless the ferrous materials are far enough away to minimize inductive heating.

5.9.5.8 Ducts shall be marked with the duct identification and safety division designations at each access point. Duct banks external to struc- tures shall be marked with surface and subsur- face location markings.

5.9.5.9 The duct bank encasement shall con-

sist of materials such as sand or reinforced con- crete, depending upon the seismic conditions at the site.

5.9.5.10 Duct banks, manholes, and hand- holes encased in reinforced concrete shall have concrete adequately reinforced so they will be able to withstand the design loads and remain functional.

5.9.5.11 If sandencased duct banks are used, adequate compaction of sand shall be provided for uniform support of the ducts.

5.9.5.12 Duct banks shall be protected from tornadegenerated missiles or turbine missiles by adequate earth cover and other similar means. Manholes and handholes shall be af- forded equivalent protection.

5.9.6 Combination Support Requirements. Where supports carry more than one type of raceway, a mechanical system, or both, the load combination shall be considered in the design. The combination support shall be designed as seismic Category I and shall meet the require- ments of this standard.

5.10 Structural Design Criteria 5.10.1 Loads and Load Combinations. The

loads identified in 5.10.1.1 shall be considered in the design of raceway systems and under- ground duct banks.

5.10.1.1 Loads 5.10.1.1.1 Dead Loads (DL). The dead

load shall consist of the weight of the raceway system, cables, fireproofing materials, and other permanently attached loads. The weight of cable shall be based on the maximum allowable race way fill. For underground duct banks, the dead load shall include the soil pressure and any hy- drostatic water pressure.

5.10.1.1.2 Live Loads (LL). The live load shall consist of those static loads supported by the raceway system that are temporary in na- ture. These loads, when applicable, shall consist of but not be limited to concentrated loads due to installation or maintenance (see 5.9.3.1). Where applicable, vehicular traffic, railroads, and other surface loads shall be included as live

12

loads for underground duct banks. 5.10.1.1.3 Thermal (T) Loads. Where

thermal loads are to be included, they shall con- sist of the most critical transient or steady-state condition for the load combination under con- sideration. In most applications, thermal loads are not a consideration.

5.10.1.1.4 Safety Relief Valve (SRV) Loads. An SRV load is a dynamic load other than seismic that is specified at the system an- chorage by response spectra or time history mo- tions. This load is applicable only to boiling water reactor (BWR) plants. Other dynamic ef- fects, such as chugging, pool swell, condensation oscillation loads, etcetera, shall be included along with SRV load effects as appropriate for the postulated accident conditions.

5.10.1.1.5 Operating Basis Earthquake (OBE) Loads. An OBE is a seismic load imposed on raceway systems generated by the OBE. The seismic loads from the three principal directions shall be determined for this condition. For un- derground duct banks, earthquake loads shall include the effects of seismic waves, such as shear and compressive waves, dynamic soil pres- sure, and inertia loads.

5.10.1.1.6 Safe Shutdown Earthquake (SSE) Loads. An SSE is a seismic load imposed on raceway systems generated by the SSE. The seismic loads from the three principal directions shall be determined for this condition. For un- derground duct banks, earthquake loads shall include the effects of seismic waves, such as shear and compressive waves, dynamic soil pres- sure, and inertia loads.

5.10.1.2 Load Combinations. The raceway and underground duct system shall be designed to withstand the effects of the folowing load com- binations. If applicable, missile loads shall be included in the extreme environmental load combinations for underground duct banks.

Normal DL + T + LL DL + T + SRV

Severe Environmental DL + T + SRV + OBE

DL + T + SRV + SSE Extreme Environmental

5.10.1.3 Abnormal Loads. For raceways in- ternal to the station, abnormal loads are those generated by a postulated high-energy pipe-

13

break accident, accident pressure loads, jet im- pingement loads, pipe whip missile loads, and equipment missiles. For external raceways, ab- normal loads would be an externally generated missile. Generally, these loads have a high mag- nitude and are localized. It is not practical to consider these loads in the structural analysis of the raceway system. See ANSI/IEEE S M 384- 1981 [ll] for the design considerations associated with abnormal loads. 5.10.2 Structural Acceptance Criteria 5.10.2.1 General. The acceptance criteria

shall be developed for the raceway system. The criteria should be obtained from industry ex- perience, applicable codes and standards, man- ufacturing standards, or the ultimate load values from the test data. Appendix D contains additional guidance with respect to the use of the elastic design method.

5.10.2.2 Displacement Limits. Movement of the raceway system may occur due to design considerations such as thermal expansion or a seismic event. Displacement limits shall be im- posed on raceway systems so that all required clearances are maintained and cables remain intact to prevent loss of circuit continuity.

5.10.2.3 Testing. Where cable-tray and wireway characteristics such as section prop- erties and deflections cannot be acceptably de- termined by analysis, a test shall be performed to determine these parameters. 5.10.3 Structural Analysis 5.10.3.1 General. The structural analysis

shall be performed for the loads specified in 5.10.1.1. There are two commonly used analyt- ical methods for calculating the effects of dy- namic loads on raceway systems: dynamic analysis and equivalent static-load analysis. A selection of the analysis method shall take into account the complexity of the system and the adequacy of the analytical technique to properly predict the response of the system while under dynamic excitation and other dynamic loads (see 5.10.1).

5.10.3.2 Dynamic Analysis. Dynamic anal- ysis of a raceway system shall be performed by using the mathematical model of the raceway systems that best represents the mass distri- bution and stiffness of the various system com- ponents. Response spectra applicable to the raceway system location shall be utilized to de- fine the dynamic loads. The response spectrum is selected for the damping values defined in 5.10.3.4.

ANSI / IEEE Std 628-1987 IEEE STANDARD CRITERIA FOR THE DESIGN, INSTALLATION, AND

The spectral accelerations for each mode shall be obtained for each component of the earth- quake from the appropriate response spectrum. The representative maximum design values of the individual modal responses of interest in de- sign shall be combined in accordance with the requirements of ANSUIEEE SM 3441975 (R1980) [lo], or other methods may be used, pro- vided they are justified. These responses ob- tained for each of three orthogonal directions shall then be combined by the square root of the sum of the squares (SRSS) technique. The re- sulting seismic responses shall be combined with respective responses due to other loads accord- ing to the load combinations specified in 5.10.1.2.

5.10.3.3 Equivalent Static-Load Analysis. Equivalent static-load analysis shall be per- formed as required to obtain the responses due to dynamic loads. The mass of the system mul- tiplied by an appropriate factor (see ANSI/IEEE Std 344-1975 (R1980) [lo]) times the peak re- sponse value of the applicable response spec- trum (RS) curve at an appropriate damping value shall be used to obtain the dynamic load. The effects of simultaneous application of these components of motion, from the three separate analyses in each orthogonal direction, shall be combined by the SRSS technique. The repre- sentative maximum value of a particular re- sponse for designs such as deformations or stresses may then be calculated and combined with the response to other loads as per the load combinations specified in 5.10.1.2.'

5.10.3.4 Damping. Damping values for each raceway system shall be established and justi- fied.

6. Qualification Methods

6.1 General. Qualification of the raceway sys- tem shall be performed by analysis, test, or a combination thereof.

6.2 Analysis. Analytical procedures as de- scribed in 5.10.3.2 and 5.10.3.3 may be used for qualification of raceway systems.

Analytical results from the loads and load combinations in 5.10.1 shall be evaluated for

At this time, no standard method has been recognized for combining the responses due to SRV loads with other loads. When an accepted method is developed, i t will be incorporated into this document.

such parameters of the system as mechanical strength and alignment. Maximum displace- ment under all loading shall be computed and interference and interaction effects determined. The magnitude of the essential parameters shall be less than the established acceptable limits.

6.3 Dynamic Testing. When utilized to dem- onstrate the design adequacy for dynamic loads, dynamic testing shall be performed in accord- ance with ANSI/IEEE SM 344-1975 (R1980) [lo].

6.4 Combined Analysis and Testing. When required, the raceway system shall be qualified by a combined method of analysis and testing. The mode shapes and resonant frequencies of a typical raceway system shall be determined from testing and shall be used to verify the ad- equacy of the mathematical model.

6.5 Acceptance Criteria. The acceptance cri- teria for raceway system qualification shall be developed in the same manner as for structural acceptance criteria in 5.10.2.

7. Installation

7.1 Packaging, Shipping, Receiving, Storage, and Handling. Materials for raceway systems shall be packaged, shipped, received, stored, and handled in accordance with Part 2.2, sectians 3.0, 4.0, 5.0, 6.0, and 7.0, respectively, of ANSI/ ASME NQA-2-1983 [7] and classified to level D.

7.2 Installation of Raceway Systems 7.2.1 The raceway system shall be erected as

shown on design drawings. Attaching supports at the anchorage shall be accomplished by weld- ing, bolting, stud welding, or concrete expansion anchors. Misalignment of successive supports shall be limited so that the effects of resulting spring loads when combined with other appli- cable load effects will not exceed the design al- lowables.

7.2.2 Anchorage locations shown on design documents shall be provided with installation tolerances. These tolerances shall not compro- mise raceway separation requirements of ANSI/ IEEE Std 3841981 [ l l ] or affect the integrity of the seismic Category I structure.

7.2.3 Conduit attachments fastened to s u p ports shall be provided with tolerances that do not compromise separation requirements set forth in ANSI/IEEE Std 384-1981 [ll].

7.2.4 Installation requirements for fasteners, such as those used with welding studs, channel strut, support steel, and conduit clamps, shall include tolerances.

7.2.5 To prevent piping or duct failures or dis- placements from impairing the operation of es- sential systems or components, separation requirements for installation of raceway sys- tems shall be coordinated with the installation of high-energy piping, moderate energy piping, and HVAC ducts.

7.2.6 Welding performed in the installation of raceway systems shall be in accordance with

or ANSI/ASME 1986 Boiler and Pressure Vessel Code [5], Section 9, as applicable. Welds shall be inspected before applying any postweld coating.

7.2.7 When a prime coat of paint is required to coat bare raceway support members installed inside the reactor containment, the steel prep aration and coating shall conform to the reactor containment’s unique coating requirements.

7.2.8 Embedded conduit, joints, and fittings shall be made concrete-tight and shall be suffi- ciently restrained within the form work to pre- vent movement of the conduit due to buoyancy and other forces during concrete placement. When EMT is used, compression couplings should be utilized.

7.2.9 After installation, burrs or sharp edges that could damage cables shall be removed prior

8.4 Construction Activities. Installation and inspection activities shall be documented to fur- nish evidence that the installed raceway system meets design requirements.

8.5 Document Collection, Storage, and Main- tenance. The collection, storage, and mainte- nance of documents shall meet the requirements of ANSUASME NQA-1-1983 [6].

(9) The bottom of the trench for direct buried conduits should be reasonably flat and free of stones. A layer of stone-free soil or sand should be placed in the trench to support the first row of conduits. The duct-bank formation may be built up layer by layer, using a selected backfill between layers. The backfill should be free of stones and corrosive chemicals and be as ho- mogeneous as possible. Tamping on the backfill should be on the sides and never on top of the conduits. (10) At elevated temperatures, nonmetallic

(plastic) conduit will expand, causing possible loosening of joints and other problems related to restraining the conduit in a trench; conse- quently, during the summer months, consider- ation should be given to backfilling during the early morning or late evening hours or on a cloudy day. The integrity of the joints should be carefully checked before backfilling and the con- duit should be swabbed immediately after back- filling. (11) When EMT is used, compression couplings

should be utilized.

C2.3 Cable Tray Systems C2.3.1 Cable Tray Installation Recommen-

dations (1) Minimum vertical spacing between cable

trays in a tier should be 12 in measured from the bottom of the upper tray to the top of the lower tray. A minimum of 9 in clearance is rec- ommended between the top of a tray and beams, piping, etcetera, to facilitate cable installation. (2) Normal rung spacing of ladder-type trays

should be maintained at the centerline of the horizontal elbows.

(3) Cable tray covers should be used to protect cables from falling objects, debris, or liquids, and

the system design should prevent their accu- mulation. Ventilation requirements should be considered to minimize the cable derating. (4) Field cuts to galvanized cable trays should

be coated with a zinc-base corrosion inhibiter.

C3. Structural Design Considerations

C3.1 Testing. By subjecting a cable tray to a static loading in incremental steps and measur- ing deflection at given locations, a loaddeflec- tion curve can be plotted. If the load is increased until failure of the tray, the maximum load- carrying ability can be obtained. These data can then be used to calculate section properties, which can then be used in the static or dynamic analysis of the cable tray. Similarly, raceway support properties can be demonstrated by static-load tests.

C3.2 Equivalent Static-Load Analysis. A mul- tiplying factor of 1.5 is in agreement with ANSI/ IEEE Std 3441975 (R1980) [Cl]; however, a mul- tiplying factor other than 1.5 may be used if adequate justification is provided.

C3.3 Damping. For raceway systems qualified by dynamic testing, both for OBE and SSE, the test-response spectra should be developed at comparable damping values specified by the re- quired RS. The damping mechanism in raceway systems is a function of many parameters; fric- tion, material characteristics, and joint losses all contribute to damping. Consideration may be given to increased damping in some raceway systems due to the relative motion of electric cables.

E2. Qualification Methods

E2.1 General. Due to the complexity of the nu- merous installations of raceways in a nuclear power plant, the qualification of these systems by testing alone is not normally utilized. How- ever, dynamic testing of representative sections of systems does have value for identifying dy- namic characteristics. This information can be

ANSI / IEEE Std 628-1987

used to supplement the analytical results used for qualification of raceway systems.

E2.2 Dynamic Testing. Dynamic testing is an acceptable method of demonstrating design ad- equacy for dynamic loads. The objective of the test is to establish qualification for a postulated dynamic load based upon acceptable techniques. Specific guidance with respect to the method employed is given in ANSI/IEEE Std 344-1975 (R1980) [E1].13 The mounting of the item being tested should duplicate, as closely as possible, the in-service conditions of the system being qualified.
