005-1 005.0 CODES Afl0 STA?!DARDS 005.3 Your response to Request flo. 005.1 is unacceptable.
Footnote 6 of the Codes and Standards Rule, Section 50.55a of 10 CFR Part 50, states that the use of specific Code Cases may be authorized by the Commission upon request. Therefore, each Quality Group A com-ponent within the reactor coolant pressure boundary to which a Code Case has been applied should be identified by Code Case number, revi-sion, and title. This includes those ASME Code Cases which are iden-tified as acceptable to the Commission in Regulatory Guides 1.84 and 1.85.
Revise the FSAR to provide the information requested.
005.4 Your response to Request No. 005.2 states that in some cases portions (RSP) of the reactor coolant pressure boundary that meet the exclusion require-ments of footnote 2 of the Codes and Standards Rule, Section 50.55a of 10 CFR Part 50, and with the interface criteria as defined in the ANS Nuclear Power Plant Standard Committee Policy 2.3 (Draf t 6), are classified less than Safety Class 2.
This is an incorrect interpre-tation of the regulation and is unacceptable.
Under no circumstances, regardless of interface criteria, may a com-ponent within the reactor coolant pressure boundary, as defined in 10 CFR 50.2(V) of the Code of Federal Regulations and which meets the exclusion requirements of footnote 2, be classified less than E f' 2
) () b
C05-2 005.4 Quality Group B, Safety Class 2, (i.e., must be constructed to ASME (RSP)
(Cont'd)
Section III, Class 2, in conformance with Regulatory Position C.1 of Regulatory Guide 1.26), and, in addition, must be designed to seismic Category I requirements in conformance with Ragulatory Position C.l.a of Regulatory Guide 1.29 and the pertinent qu.litty 3ssurance requirements of Appendix B to 10 CFR Part 50.
The ANS Nuclear Power Plant Standard Committee Policy 2.3 (Draft 6) document is unacceptable for use in the licensing procc3s as the document is in conflict with Federal Regulations.
Revise the FSAR as appropriate to comply with the above requirements.
