Reference:

P.W. Marriott to R. C. Pierson, "GE Reaponse to inservice inspection (ISI) Issue of GE/NRC Meeting October 910,1991; January ti,1992, MFN No. 008 92 As a follow up to the referenced letter, a GE/NRC conference call was held on February 19,1992 to discuss the ISI sections of the ABWR SSAR. The following summarizes the staffs positions:

1. Design access for preservice and inservice examinations is an ASME Section XI Code requirement. Since ABWR is a new plant, the SSAR must commit unconditionally to design for such access,

2. The section on relief requests should be deleted in its entirety. This is a new plant and should be dedgned to meet applicable Codes and regulations without relief.

3. Specific code editions should not be referenced. The code editions used for PSI and ISI (and construction as well) are based on the date of issuance of the construction permit or the operating license, respectively, per 10CFR50 Section 50.55a. These items are considered interface requirements for utility applicanis as described in the DSER.

4. The Augmented inspection section of the SSAR must address erosion corrosion examination because it is expected to be incorporated into the Code in the near future. Also the SSAR must address pilor augmented inspection requirements of IE/NRC Bulletins and GE SILs as applied to the ABWR, 1100,.0 9203120371 920309 PDR ADOCK 05000605

5. A crisp distinction must be made in the text between exclusions, which lettain to the chssification boundary, and exemptions, which pertain to AShili Code PSI /is requirements, due to pag problems NitC has experienced with utility implementation of these requirements.

It should be noted that these pos!tiom are substantially different than those expressed by the staff at the October 010,1991 meeting and, as a consequence, Gli is withdrawing the SSAll changes in the referenced letter. The SSAll changes corresponding to the above pc.4itions will be addressed in Oli's response to SEC%91355.
