ENCLOSURE RE0 VEST FOR ADDITIONAL INFORMATION SNUPPS FSAR 490.0 Reactor Fuels Section, Core Performance Branch 490.1 Since the issuance of Construction Permits for SNUPPS plants, several significant changes have taken place that will affect our review of Section 4.2, " Fuel System Design." The most fundamental change deals with the format and content of Section 4.2 as they relate to the Standard Resiew Plan; the other changes deal with technical issues that have arisen recently. All of these changes are discussed below.
Standard Review Plan The basic fuels sections of the Standard Format (Rev. 3), the Standard Review Plan (Rev.1,1978), and the SNUPPS FSAR are all the same:
4.2.1 Design Bases, 4.2.2 Description and Design Drawings, and 4.2.3 Design Evaluation. Unfortunately, 4.2.1 of the Standard Format (and, hence, of the SNUPPS FSAR) does not of all the design bases as does (usually numerical) statement clearly call for a quantitative the Standard Review Plan.
Similarly, the other sections of the Standard Format and the SNUPPS FSAR mix up design bases, design descriptions, and design evaluations, but that information is sorted out clearly in the Standard Review Plan.
Because of improvements in clarity and completeness in this 1978 version of the Standard Review Plan, we will conduct our review and prepare the SER according to the SRP.
Our questions, then, will not be open-end, but they will simply ask for the residual. information called for in the SRP but not present in the SNUPPS FSAR. There are, thus, two options at this stage of the review.
Option 1 - You could revise Section 4.2 of the SNUPPS FSAR to follow the details of the SRP (remember, the basic organization structure would be unchanged)..This would automatically bring out all of the information that is needed.
Option 2 - A cross reference could be provided to link each item in the SRP with a paragraph in the SNUPPS FSAR. This method
-would leave Section 4.2 of the SNUPPS FSAR in its present format, but'might lead to additional questions since all of the information is not present.
S
+..,,
, We recommend Option 1.
Revision 1 of the SRP, to which we refer, was formally issued more than two years ago. Therefore, we do not view this change as either precipitous or disruptive.
Furthermore, it is likely that you will have to identify and justify all deviations from the SRP under the provisions of a proposed rule (Federal Recister 45, p 67099, October 9,1980) since your SER will be issued af ter January 1,1982.
We urge you to provide the information that would be needed to demonstrate compliance with the SRP at your earliest convenience.
To help you anticipate an inninent revision to SRP-4.2, the following comments are provided.
Revision 1 - This revision was issued in October 1978 and contains all of the basic requirements that you need to address.
It will not be changed significantly by the planned revision.
Revision 2 - This revision is planned for April 1981 and is the revision alluded to in the notice of proposed rulemaking on SRP compliance.
In SRP-4.2 this revision will (a) add acceptance cri'eria for mechanical response to seismic and LOCA loads, and (b) make editorial changes largely confined to adding and correcting citations to regulations and regulatory guides that are already addressed in Rev.1. The acceptance criteria for mechanical response were recently implemented as part of the resolution of Unresolved Safety Issue, Task A-2 and are given in Appendix E of NUREG-0609. Therefore, you can base the SNUPPS.FSAR revisions o1 SRP-4.2 Rev.1 (current version) plus Appendix E of NUREG-0609, :qd last-minute changes in referencing can be made in Aprit prior to your submittal of the additional fuel-related information.
Recent Technical Issues The following is a list of current technical issues that have frequently been noted as outstanding issues in recent SERs and that -should be given special attention in the SNUPPS FSAR.
l '. Supplemental ECCS analysis with NUREG-0630, 2.
Combined sef snic and LOCA loads analysis.
3.
Enhanced fission gas release analysis at high burnups.
- 4.'

5.
