Introduction As part of their review of the ABWR Design Certification application, NRC staff have requested that GE provide a cross reference between the following:

4 a) The plant safety analyses and other safety-related issues described in the Safety Analysis Report (SAR) and b) The inspections, tests, analyses and acceptance criteria (ITAAC) included in the Certified Design Material (CDM) being prepared by GE for the ABWR.

This cross reference is intended to be a review aid which will assist the NRC staff in concluding that plant characteristics of particular importance to safety will be adequately confirmed by the CDM ITAAC process; i.e...the as-built facility has the characteristics which are consistent with the plant safety analyses assumptions and the resolutions of the plant safety-related issues described :n the SAR.

The folowing Tables 1 through 10 provide cross references for ten safety-related areas described in the SAR. GE believes the material in this memorandum is aimed at assisting the staff review process; consequently, it is informal in that it is not intended to be part of the SSAR or Design Control Document. These cross references are consistent with ABWR SSAR Tables 14.3-1 through 14.3-10.
