SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION NRC INSPECTION REPORT 99900404/97-02
)
Dear Mr. Liparulo.
Thank you for your letter dated April 17,1998, which responds to our letter dated April 3,1998, which requested additionalinformation relative to closure of the Notice of Nonconformance and Unresolved item identified in NRC Inspection Report 99900404/97-02. We also acknowledge receipt of your letter dated April 2,1998, which presented the results of Westinghouse's Design Assurance Review and your presentation to the staff on April 13,1998, of the results of such review. The staff requested Westinghouse to assess the adequacy of the AP600 QA design t
review process and the integrity of the design in our letter to you dated January 28,1998.
The staff has completed its review of 'hese documents and has concluded, with the exceptions identified in the Enclosure to this letter, that Westinghouse has adequately addressed the staff's concerns relative to the potential generic implications of our findings. In responding to the staff's concerns, your response should clearly address the specifics of each concern and be submitted consistent with a schedule that will allow the staff sufficient time for review prior to the staff's May 15,1998 scheduled briefing of the ACRS on Chapter 17 of the advanced FSER.
With respect to Nonconformance 99900404/97-02-01, item 1, the staff agrees that the AP600 Technical Specifications (TS) self-assessment conducted by Westinghouse to address the NRC's concerns (regarding compliance of the AP600 design with 50.36 requirements) was thorough and comprehensive and, therefore, responsive to the staff's finding. Since the staff is continuing to interact with Westinghouse on the acceptability of the AP600 TS, the compliance
/
of the AP600 design with 650.36 will be established and documented by the staff in Chapter 16,
" Technical Specifications," of the FSER.

l Enclosure DISPOSITION OF REMAINING INSPECTION REPORT ISSUES AND REQUEST FOR ADDITIONAL INFORMATION WESTINGHOUSE LETTER DATED APRIL 17,1998 UPDATED CORRECTIVE ACTION PLAN
- 1. Unresolveditem 99900404/!?7-02-03 With respect to Attachment 1," Updated Corrective Action Plan," to Westinghouse letter DCP/NRC-1345, dated April 17,1998 (specifically, but not limited to item 8), the staff concludes that there are sufficient concerns that question the validity of the AP600 WGOTHIC model and analysis to support design certification, identified by the DAR, which have not been addressed.
As discussed during a conference call with members of the staff and Westinghouse on April 17, 1998, the staff requests that Westinghouse explicitly document the bases for closure of issues identified by the DAR team that required further discussions with 'he calculation note authors and user (s) before Westinghouse could reach a conclusion on their acceptability (i.e., those for which Westinghouse could not review or understand the analyses and verify their adequacy without recourse to the originator).
- 2. Westinahouse crocosed chances to SSAR Chacter 3 I
With respect to Westinghouse proposed changes to SSAR Chapter 3, as discussed during the DAR presentation and subsequent discussions with Westinghouse on April 17,1998, Westinghouse needs to confirm that the criteria used for the final design of the nuclear island structures are consistent with those committed to in the latest version of the SSAR.
