SUBJECT:

REVIEW SCHEDULE AND PROCESS FOR THE AP600 DESIGN CERT APPLICATION

Dear Mr. Lipirulo:

The Nuclear Regulatory Commission (NRC) staff has reviewed your July 26, 1996, letter which provided revised submittal dates for some of the necessary information for the review of the AP600 design certification application.

However, this is not a complete schedule of the key items needed to complete the staff's review. We request that Westinghouse submit a current and comprehensive activity schedule. The schedule should identify all key activities, including submittals, design reviews, and issue resolution. This will enable the staff to develop a firm schedule for the completion of its review.  ;

I In response to your statement in the July 26, 1996, letter that certain SSAR information was removed because you believe the information to be "extrane-ous," the staff does not agree with Westinghouse that all of this information is extraneous. Part 52.47(a)(2) of Title 10 of the Code of Federal Regula-tions requires the application to contain a level of design information sufficient to enable the Commission to reach a final conclusion on all safety questions associated with the design. In your letter you stated that Westing-house would resubmit information to the SSAR required to reach a safety conclusion and correctly identified that one branch of the staff agreed to work with Westinghouse (after Revision 6) to return the necessary information.

However, we did not expect this exercise to be a continual process of removal in Revisions 6 through 9 and later resubmission. This has increased the review time in several areas. Through subsequent discussions with Vesting-house, the staff has Lt;n told that you do not expect to change more informa-tion after the current revision However, if this should change, w(Revision e request that 9) you unless requested do not by the staff.

remove SSAR information without first discussing your intent to do so with the appropriate staff members. Prior communication with the staff will greatly improve review ld efficiency and will avoid a possible delay in the completion of the review.

M' One of the issues discussed at the July 17, 1996, Senior Management Me6 ting was the procedure for closure of open items. Westinghouse indicated the staff could be writing its final safety evaluatfon report sections for those chapters where final SSAR sections had beer, provided. However, considerable discussion occurred as to whether the SSAR sections Westinghouse characterized 330103 {[h 9609300258 960926 PDR ADOCK 05200003 A PDR

Mr. Nicholas J. Liparulo September 26, 1996 as final were indeed final. It was agreed that the open items, not SSAR chapters, were important indicators of the progress toward closure. A measure of progress toward closure could be obtained from the open items tracking system (OITS). Westinghouse indicated that they would provide an update of

OITS to the~ staff. The staff would then review OITS and update its status.

! Westinghouse provided a partial update on July 19, 1996, and provided a full i update on August 29, 1996.

i

! The staff _has noticed that Westinghouse is now emphasizing the closure of open items, as evidenced by several facsimiles received that indicate the "done-

ness" of SSAR chapters ~or sections and a statement of Westinghouse's closure i of associated open items. These " doneness" statements are useful in that they l

provide a clear understanding what Westinghouse believes the status to be.

i However, in some cases Westinghouse's closure status appears based on the submittal. of a document and does not reflect on-going discussions or reviews that will require further action by Westinghouse. We request that Westing-house confirm its,"donaness" claims by following these Westinghouse staff l facsio(les. with a' formal transmittal to the staff.

j Sinc'e the requests for additional information (RAIs) constitute a large portion of the remaining open items, and the information Westinghouse will

. provide.in the responses to these open items will include necessary informa-tion to complete NRC's review, the staff requests that you include an RAI  ;

response schedule in your comprehensive activity schedule. Also, to be  !

! included, but not limited to, should be the final computer code benchmarking

and validation reports', thermal hydraulic uncertainty results and documenta-

! tion, shutdown evaluation report, Level 2/3 probablistic risk assessment, i i human. factors WCAPs, revisions to the SSAR (specifically the change to the design control document format and the incorporation of RAI information), and inspections, tests, analyses and acceptance criteria. '

The submittal of a comprehensive activity schedule from Westinghouse would

^ greatly assist the staff in developing a review schedule for the final safety evaluation report. While preparing this schedule, we are willing to hold project telephone conferences or meetings to discuss resource limitations or other items that have impacted the schedule or provide information that could assist your effort.
