In SRM dated June 26, 1990, and April 1, 1991, the Commission provided its decisions on SECY-90-016 and SECY-91-078 as they apply to evolutionary designs. The Commission will be reviewing the basis for the approach that the staff is proposing for those issues discussed in the draft Commission papers of February 27 and July 6, 1992, and, accordingly, may at some future point in the review determine that such issues involve policy questions that the Commission may wish t o consider. These issues are considered fundamental to agency decisions on the acceptability of the ALWR designs. ensure satisfactory implementation of Commission guidance regarding these matters during its review o f individual applications for final design approval and design certification.
There are no open issues pertain ng to the Requirements Document for evolu- tionary plant designs other than policy issues on which the staff has taken a position, but for which the Comm ssion has not had the opportunity to provide guidance. In addition, the staff concludes that there are issues that must be satisfactorily resolved before it can complete its review of the Requirements Document for passive plant designs. These issues are summarized in Section 4 of Volume 1 and discussed in detail in this report.

On September 7, 1990, EPRI submitted Revision 1 of the Requirements Document for evolutionary plant designs, modifying the document in its entirety. April 26 and November 25, 1991, and April 17, 1992, EPRI submitted Revi- sions 2, 3 , and 4 , respectively. Volume 2 o f this report addresses the Evolutionary Document for evolutionary plant designs through Revision 3. Where possible, the staff's review included consideration of Revision 4 of the Requirements document.

1.2 PurDose and Requlatorv Status of EPRI's ALWR Utility Reauirements Document

EPFlI ’ s ALWR Uti 1 i ty Requirements Document , because it is an agreement between th(1 vendors and the nuclear power utilities, identifies what utilities desire in future designs. The Requirements Document has no legal or regulatory stztus. Conimission’s regulations, regulatory guidance, or policies, nor is it intended to be used as a basis for supporting final design approval and design certifi- cation (FDA/DC) for a specific design.
It is not intended to demonstrate complete compliance with the
- Conimi ssion Guidance
In its staff requirements memorandum (SRM) dated December 15, 1989, the Conmission assigned the review of the Requirements Document for evolutionary plant designs priority equal to those of General Electric Company’s Advanced Boiling Water Reactor and Combustion Engineering, Inc.’s System 80t. In adcition, the Commission directed the staff to compare future designs against thc Requirements Document for evolutionary plant designs.
In the same SRM, the Commission directed the staff to complete its review of the Requirements Document for passive plant designs before it submitted the results o f its review of the licensing review basis (LRB) for passive designs to the ACRS. Although a design certification applicant is no longer required to submit an LRB because the promulgation of Part 52 of Title 10 of the Q& - of Federal Resulations (10 CFR Part $ 2 ) negated the need for such a document, the staff interprets this guidance as directing it to complete its review of the Requirements Document for passive plant designs before significant inter- action with the ACRS begins on these designs. that, with the issuance of the DSER on Volume 3 in April 1992, this has been accompl ished.
It is the staff’s position
In its SRM o f June 22, 1990, the Commission directed the staff to formally resolve major technical and policy issues in the context of the review of the Requirements Document for passive plant designs. The staff has identified such issues during its review o f Volume I11 o f the ALWR Utility Requirements Document and conceptual design information on the passive ALWRs. The staff developed the draft Commission papers dated February 27 and July 6, 1992, to address resolution of these issues. policy issues, the staff will continue to evaluate resolutions proposed by EPAI and the ALWR vendors, and will address them in future Commission papers.
To ensure timely resolution of these
1.3 EPRI’s Policy Statements
The ALWR Uti1 ity Steering Committee established policies to provide guidance for the overall development of the EPRI’s ALWR Utility Requirements Document and to provide the plant designer with guidance in applying the design criteria. Although not design criteria themselves, these policies cover fundamental principles that have a broad influence on the design criteria of the Requirements Document. These policies include consideration of simplifi- cation, design margin, human factors, safety, regulatory stabilization,

standardization, use of proven technology, maintainability, constructibility, quality assurance, economics, protection against sabotage, and environmental effects.
1.4 ALWR Desiqn Bases
The term "ALWR design bases," as defined by EPRI, refers to the three sets of requirements that form the foundation for the ALWR design criteria. The first set of requirements forms the "licensing design basis," which includes the requirements necessary to satisfy regulatory criteria. These requirements and associated analytical methods are based on conservative, NRC-approved methods, and equipment is designed to safety-grade standards. "risk-evaluation-basis," which extends the licensing design basis t o meet public safety objectives. risk evaluation basis methods. The third set is the "performance design basis," which is based on economic and investment protection considerations for a utility and for which realistic, designer-selected, best-estimate methodology is used. to provide an adequate level of safety, whereas the risk evaluation and performance design bases provide additional or enhanced protection.
The second set is the
Probabilistic risk assessments are used for the

1.5 Requlatorv Stabilization
Consistent with the overall ALWR program approach, as described in NUREG-1197, regulatory stabilization for an ALWR design can be achieved through the identification and resolution of plant optimization subjects and generic safety and licensing issues.
Plant optimization subjects are proposals, initiated by EPRI, to deviate from regul atory requirements. EPRI proposes to resolve these issues by providing technically supportable alternatives to current regulatory requirements. Table 1.2 contains a list of EPRI's proposed plant optimization subjects and their applicability to the evolutionary and passive plant designs. issues are identified for both the evolutionary and passive plant design criteria in Section 2 of Appendix B to Chapter 1 of Volumes I1 and 111 of the Requirements Document. The staff's evaluation is provided in the correspond- ing sections of Volume 2 of this report and the April 1992 draft of Volume 3 of this report.
These
In addition, EPRI specifically addressed those generic safety issues that were classified as "high" or "medium" priority as of January 1990 in Section 3 of Appendix B to Chapter 1 of Volumes I1 and I11 of the Requirements Document. The staff's evaluation of the generic safety issues specifically addressed by EPRI and those unresolved safety issues and generic safety issues that are considered applicable to ALWRs is provided in the corresponding sections of Volume 2 of this report and the April 1992 draft of Volume 3 of this report.
1.6 NRC Review Criteria

In addition to addressing such matters relative to safety, the staff also has provided constructive comments on the document that, while not specifically regulatory in nature, would offer improvements in its requirements. will review an actual ALWR plant in accordance with the most current version of the SRP and will follow the SRP criteria, except for those instances where the staff has specifically accepted other positions in EPRI’s ALWR Utility Requirements Document and those positions have been endorsed in the final SER for the ALWR program.

Finally, as discussed in Section 1.2, the staff’s review of the Requirements Document is not intended to substitute for any portion of the staff’s review of future applications for final design approval and design certification.
Additional Criteria Governinq the Review of the Reauirements Document for Passive Plant Desiqns
The licensing design-basis analysis of the Requirements Document for passive plant designs relies solely on the passive safety systems to demonstrate compliance with the acceptance criteria for various design-basis transients and accidents. Consequently, uncertainties remain concerning the performance of the unique passive features and overall performance of core and containment heat removal because of lack o f a proven operational performance history. For example, uncertainties exist about the performance of check valves in the passive safety systems, which operate at low differential pressures provided by natural circulation or gravity injection. These low pressures may not provide sufficient force to fully open sticking check valves (i.e., pumped emergency core cooling systems are more likely to overcome stuck valves). a result, these uncertainties enhance the importance of the active non-safety- related systems in providing the defense-in-depth protection to prevent and mitigate accidents and core damage. Therefore, the review of the passive designs requires a review of not only the passive safety systems, but also the functional capability and availability of the active non-safety-related systems to provide significant defense-in-depth protection and the capability to prevent accidents and core damage.
As
8 For those active systems that perform defense-in-depth functions, the Require- ments Document for passive plant designs specifies systems and equipment design and performance requirements. These include radiation shielding to permit access following an accident, the availability and redundancy of non- safety-related electric power, and protection against internal hazards, as well as safety analysis and testing required to demonstrate system capability for defense-in-depth considerations. However, the Requirements Document does not provide specific requirements pertaining to the reliability of these systems. EPRI has indicated that it is evaluating the specific reliability targets and other measures to ensure that the passive plants will meet performance requirements and that it will address these safety concerns for both passive safety and active non-safety-related systems.
In addition, technical specification development is a subset of the overall regulatory treatment of the passive designs. to establish re1 iabil ity-based technical specifications (TS) for the passive plant designs to determine which systems and components (including certain non-safety-related systems) will require the imposition of TS, and the

2 POLICY ISSUES
In the staff requirements memorandum (SRM) dated August 24, 1989, the Commis- sion instructed the staff to provide an analysis detailing where the staff proposes departure from current regulations or where the staff is substanti- ally supplementing or revising interpretive guidance applied to currently licensed light water reactors. Appendix 6 to Chapter 1 of Volume 2 of this report gives the staff's regula- tory analysis of those issues identified for the evolutionary plant designs. Appendix 6 to the DSER on Chapter 1 of Volume 3 of the Requirements Document gives the regulatory analysis o f those issues identified for the passive plant designs. These issues have been addressed in Commi ssion papers SECY-90-016, "Evolutionary Light Water Reactor Certification Issues and Their Relationship to Current Regulatory Requirements," and SECY-91-078, "Chapter 1 1 of the Electric Power Research Institute's Requirements Document and Additional Evolutionary Light Water Reactor Certification Issues," and in draft Commis- sion papers, "Issues Pertaining to Evolutionary and Passive Light Water Reactors and Their Relationship to Current Regulatory Requirements," and "Design Certification and Licensing Policy Issues Pertaining to Passive and Evol utionary Advance Light Water Reactor Designs," that were issued on February 27 and July 6, 1992, respectively.
The staff considers these to be policy issues.
In its SRMs dated June 26, 1990, and August 15, 1991, the Commission provided its decisions on SECY-90-016 and SECY-91-078 as they apply to evolutionary desilps.
The -ebruary 27 and July 6, 1992, draft Commission papers have been forwarded to tlie Advisory Committee on Reactor Safeguards. views in the final paper and document its final positions before seeking Commission approval. reviewed by the Commission, and, therefore, do not represent agency positions.
These policy issues are considered fundamental to agency decisions on the acceptability of the ALWR designs. To aid in identifying its positions, the stafF underlined those for which it requested Commission approval in the Commission papers discussed above. Table 2.1 contains a list of these policy i s s u m and their applicability to the evolutionary and passive plant designs. Table 46.1 o f Appendix 6 to Chapter 1 of Volume 2 of this report lists the i s s w s that are applicable to the Requirements Document for evolutionary plant designs with the cross-reference to the chapters and sections in which they are discussed. Table 56.1 of Appendix 6 to Chapter 1 of the April 1992 draft of Volume 3 of this report lists those issues that are applicable to the Requirements Document for passive plant designs at the time of issuance along with the appropriate cross-references.
In addition, Appendix E lists the papers that the staff has forwarded to the Comm.tssion regarding policy issues that the staff has identified to date for both evolutionary and passive ALWRs. resuit of its review of the EPRI's ALWR Utility Requirements Document, the finai design approval and design certification applications for the evolution- ary plants, and the conceptual design information on the passive plants.

4 OUTSTANDING ISSUES
During its review of EPRI's ALWR Utility Requirements Document, the staff ideritified several items for which additional information is required before the staff can reach a final conclusion. The staff considers these issues to be cutstanding. These outstanding issues fall into one of three categories: (1) open policy issues on which the staff has taken a position, but for which the Commission has not provided guidance; (2) open issues that must be sati- sfactorily resolved before the staff can complete its review of the Require- ments Document; or (3) confirmatory issues for which the staff will ensure that EPRI meets it commitments to revise the Requirements Documerlt. outstanding issues for the entire Requirements Document, provided by chapter or appendix with references to appropriate sections of the SER chapter or appendix given in parentheses, are listed below.

5 VENDOR- OR UTILITY-SPECIFIC ITEMS
During its review of EPRI's ALWR Utility Requirements Document, the staff identified items that were inadequately addressed in the document or were i s s u s that could not be addressed generically. These items will have to be satisfactorily resolved during the staff's review o f a vendor- or utility- specific application (i .e., an appl ication for final design approval and desilgn certification or a combined construction permit and operating 1 icense).
As discussed in Section 1 . 2 of this report, the Requirements Document has no legal or regulatory status and is not intended to demonstrate complete compliance with the Commission's regulations, regulatory guidance, or poli- cies. It is not intended to be used as a basis for supporting final design apprsval and design certification for a specific design, nor is it to be used to substitute for any portion of the staff's review of future applications for final design approval and design certification. Specifically, satisfactory resolution of the items identified in this section for a vendor- or utility- specific application will not, by itself, support a finding that the applica- tion complies with the Commission's regulatory requirements. The staff will p e r f m n a complete licensing review of these applications using the Standard Revi2w Plan (NUREG-0800) and other appropriate Commission guidance. tory resolution of the vendor- or utility-specific items constitutes only one portion of the staff's review.
The iendor- or utility-specific items for the entire Requirements Document, provided by chapter or appendix with references to appropriate sections of the SER :hapter or appendix given in parentheses, are listed below. The designat- ors in front of each issue provide a unique identifier for each issue. The lettlw "E" or "P" indicates that the issue applies to evolutionary or passive plant designs, respectively. The first number designates the chapter in which it i s identified. The letter that follows designates the appendix, if applicable. The letter V designates that i t is a vendor- or utility-specific item. Section 1 . 5 of each chapter or appendix.

In addition to
Subject to the resolution of the identified outstanding issues and vendor- and utility-specific items listed in Sections 1.4 and 1.5 of each DSER chapter or appendix issued on April 24, 1992, the staff concludes that the requirements established in the Requirements Document for passive plant designs (Volume 111) do not conflict with current regulatory guidelines and are acceptable. However, b,y themselves they do not provide sufficient information for the staff to determine if the plant design will be adequate. Therefore, appli- cants referencing the Requirements Document will be required to demonstrate compliance with the additional guidance provided in the Standard Review Plan (NUREG-0800), or provide justification for alternative means of implementing the associated regulatory requirements.
In its August 24, 1989, SRM, the Commission instructed the staff to provide an analysis detailing where the staff proposes departure from current regulations or where the staff is substantially supplementing or revising interpretive guidance applied to currently licensed LWRs. policy issues. Appendix B to the DSER on Chapter 1 of the Requirements Document for passive plant designs gives that analysis. these issues to the Commission in draft Commission papers dated February 27 and July 6, 1992. When the staff finalizes these Commission papers, the Commission will complete its review of the basis for the approach that the staff is proposing for those issues and, accordingly, may at some future point in the review determine that such issues involve policy questions that the Commission may wish to consider. The approaches to resolving these issues have not been reviewed by the Commission, and, therefore, do not represent agency positions.
The s t a f f considers these to be
The staff forwarded
In addition, certain technical issues still have to be resolved before the staff can complete its review.
The following conclusions are based on the staff’s review as documented in the April 1992 draft SER (Volume 3 of this report). The final SER, scheduled to be issued in September 1993, will give the final results of the staff’s review of EPRI’s ALWR Utility Requirements Document for passive ALWR designs.
Therefore, on the basis of its review to date, the staff concludes that EPRI’s ALWR Uti1 ity Requirements Document for passive plant designs (Volume 111) specifies requirements that, subject to the resolution of the identified outstanding issues and vendor- and uti1 ity-specific items, if properly translated into a design and constructed and operated in accordance with the NRC regulations in force at the time the design is submitted, should result in a nuclear power plant that will have all the attributes required to ensure that there is no undue risk to the health and safety of the public or to the environment. In addition to complying with existing regulations, such a facility would also be consistent with the Commission’s policies on severe- accident protection.

REPORT BY THE ADVISORY COMMITTEE ON REACTOR SAFEGUARDS
P r o g r a m Summary
UNITED STATES NUCLEAR REGULATORY COMMISSION
ADVISORY COMMITTEE ON REACTOR SAFEGUARDS WASHINGTON, D. C. 20555
August 18, 1992
The Honorable Ivan Selin Chis irman U. ::. Nuclear Regulatory Comniission Washington, D.C. 20555
I Dedr Chairman Selin:
SU3JECT: ELECTRIC POWER RESEARCH INSTITUTE ADVANCED LIGHT WATER REACTOR UTILITY REQUIREMENTS DOCUMENT -- VOLUME 11, EVOLUTIONARY PLANTS
During the 387th and 388th meetings of the Advisory Committee on Re3ctor Safeguards, July 9-11 and August 6-8, 1992, we reviewed the NR3 staff's Final Safety Evaluation Report (FSER) for Volume I1 of th2 Electric Power Research Institute's (EPRI) Advanced Light Water Resctor (ALWR) Utility Requirements Document (URD) for Evolutionary Plants. Our Subcommittee on Improved Light Water Reactors held meetings on June 17-18 and July 27, 1992, to review this subject. During these meetings, we had the benefit of discussions with representatives of the NRC staff and EPRI. We also had the benefit of the documents referenced.
In the early 1980s, EPRI established the ALWR program to-support the United States utility industry efforts to ensure a viable nuclear power generation option for the 1990s and beyond. The objective of the program was to ensure that future nuclear power plants would be safer, simpler, more robust with greater margins, more easily operated and maintained, and more certain of being constructed and licensed without delays. This was accomplished using utility experience, by establishing design philosophy, producing design criteria and guidance to achieve the objective, and addressing the policies and regulations of the NRC.
The EPRI ALWR URD is a compendium of technical requirements for design, construction, and performance of ALWR nuclear power plants for the 1990s and beyond.
0 Volume I, "ALWR Policy and Summary of Top-Tier Requirements,Il is a management-level synopsis of the URD, including the design objectives and philosophy, the overall physical configuration and features of a future nuclear plant design, and the steps necessary to take the proposed ALWR design criteria beyond the conceptual design state to a completed, functioning power plant.
The URD consists of three volumes:
Prog,*am Summary F- 1
The Honorable Ivan Selin 2 August 18, 1992
0 Volume 11, llALWR Evolutionary Plant, It consists of 13 chapters and contains utility design requirements for an evolutionary nuclear power plant (approximately 1350 Mwe).
0 Volume 111, 'IALWR Passive Plant," contains utility design requirements for passive nuclear power plants (approximately 600 Mwe).
We have followed the development of the EPRI ALWR program from its inception and offered suggestions regarding safety improvements on several occasions. We also held numerous subcommittee and Committee meetings to consider and discuss the development of the EPRI URD program and the NRC staff's reviews.
The staff's review of the URD was conducted as described in "REG- 1197. As noted therein, the staff used NUREG-0800, "Standard Review Plan (SRP) for the Review of Safety Analysis Reports for Nuclear Power Plants,tt for review guidance. In addition, the staff's review reflects the requirements of 10 CFR 52, the Commission's policy statements on severe accidents, and the safety goals.
Although the SRP was used by the staff as guidance, the level of detail in the EPRI submittal did not permit a review of its completeness. (The SRP was written to support the review of safety analysis reports on specific plant designs for which a significant amount of design and construction information was available.) The staff conducted its review with the understanding that EPRI design criteria would meet all current regulations, except where deviations were identified. The staff's review of the URD focused primarily on determining whether the EPRI criteria did or did not conflict with current regulatory requirements.
In its review of Volume I1 of the URD, the staff identified a number of issues that will require additional information before the staff can reach a final conclusion. Initially, the staff divided the outstanding issues into three categories: (1) open policy issues on which the staff has proposed a position, but for which the Commission has not yet provided guidance, (2) open issues that must be satisfactorily resolved before the staff can complete its review of the URD, or (3) confirmatory issues for which the staff will ensure follow up of commitments in the URD.
At this date the staff has identified 21 open policy issues that are included in a draft Commission paper, ItIssues Pertaining to Evolutionary and Passive Light Water Reactors and Their Relationship to Current Regulatory Requirementstt that was issued on February 27, 1992. We provided our recommendations on the open policy issues pertaining to evolutionary plants in our letters which addressed SECY-90-016, SECY-91-078, and the draft SECY paper of February 7, 1992.
Program Summary F-2
The Honorable Ivan Selin 3 August 18, 1992
The staff has handled the remaining 410 open issues which were identified in the FSER for Volume I1 by classifying them as Vendor or Utility Specific Itemst1 which must be satisfactorily addressed during the staff's review of a vendor- or utility-specific arplication. The staff plans to issue a supplement to the FSER after all evolutionary policy issues have reached final resolution. The staff indicated that they plan to interact with EPRI in an attempt to resolve significant open issues which may be resolved generically, and to include in a supplement any which are resolved.
We recommend generic resolution of as many of these issues as pcssible.
We commend EPRI for developing a comprehensive set of requirements. These will aid in the design of nuclear plants which will be safer, simpler, more robust, and more easily operated and maintained.
We commend the NRC staff for a very thorough review of the EPRI AIlWR Evolutionary URD, and its work with EPRI to identify and r€solve many issues relevant to licensing future LWRs. We recognize the NRC staff's position that its review necessarily is ir complete.
Sincerely,
David A. Ward Chairman
