- Washington, D.C. T15$5 Attention: Charles L hiiller, Director Standardization and Non Power Reactor Project Directorate

Subject:

Pilot inspections, Tests, Analyses and Acceptance Criteria (ITAAC)

Package for the AllWR Certification Enclosed are thirty four (34) copies of nine pilot examples of proposed Tier i design certification material for the OE ABWR. This material includes a proposed Tier i design description (Rule content) as well as the ITAAC entries which derive from this description. This submittal fulfills the commitment made by GE at the August 21,1991 Commission review of issues associated with the ITAAC required by 10CFR Part 52.

The attached set of nine pilot examples is intended to cover representative AllWR systems and

includes nuclear island mechanical systems, a turbine island mechanical system, a seismic Category structure, a control system and an electrical power distribution system. The purpose of a pilot approach is to present examples for NRC rev,ew i with the intent that GE, NRC and Industry will rapidly reach a consensus on definition of Tier 1 scope and content. This definition can then be used by OE to prepare a full set of ITAAC material to support the AllWR Design Certification application.

The attached material has been . reviewed by industry representatives on the NUh1 ARC-Predictable Licensing and Stable Regulation Subcommittee. As a result of this NUh1 ARC review,

,. OE believes the scope and content of the pilot material is consistent with the industry approach L .

outlined in the report " Report of the Task Force on inspections, Tests, Analyses and Acceptance

j. Criteria," NUhi ARC 90-l ', December 1990.

September 20,1991 lil?N 9167 Page 2 Gl! and the industry believe there should be early meetings with the staff in order to rapidly reach apeement on ITAAC scope. 011 personnel are available to support such meetings, and we are discussir:g eaily October dates for a kick off meetin,; with you and your staff. We would envision part of the meeting being a 013 presentation on t ie principles used to select ITAAC scope and content as well as detailed technical discussions on individual pilots. To support this review process, Gil is currently preparing a memorandum which will set out the assumptions which pided the pilot ITAAC submittal. We intend to submit this memorandum to the staf f as soon as possible, but certainly in advance of the suggested meeting.

The attached material does not include any of the generic ITAAC diwussed in both NUMAl(C i 9015 and Sf!CY 91 178. The industry approach to this type of ITA AC is still under development, and a final direction has not been determined. Ilowever, it is clear that ITAAC will most likely have to be developed for selected generic subjects such as seismic design, seismic qualification and environmental qualification. We suggest a discussion of generie ITAAC isst"s be on the agenda for the kick off meeting.

We look forward to receiving your comments on these pilot ITAAC examples as well as an early and positive response to our suggested kick of f meeting. If you have any questions on these issues, please do not hesitate to contact Mr. Joseph Quirk on (403) 925 6219 Sincerely, hAo P. W.
