lar case.24 1. HeThe reviewer determines that the design of the steam generators, as described in the 25 PSAR, will permit access for the specified inspection techniques, as required by General Design Criterion 32. HeThe reviewer also evaluates the design of the steam generator 26 27 as described in the FSAR and the Technical Specification inservice inspection program to determine the degree to which the recommendations of Regulatory Guide 1.83 have been followed. 2. HeThe reviewer determines that the inspection techniques for the tubes, the selected 28 number of tube samples, the inspection intervals, and the actions to be taken in the event defects are observed are in accordance with the positions stated in the regulatory guideRegulatory Guide 1.83 and applicable NUREGStandard Technical Specifications. 29 The reviewer determines the extent to which NRC staff recommendations as described in Generic Letter 85-02 (Reference 12, see also Reference 8) have been incorporated in the applicant's (licensee's) steam generator tube inspection program. HeThe reviewer also 30 31 determines that a baseline inspection will be made prior to startup of the plant. 3. The reviewer should determine that the applicable tube plugging guidance as established in Regulatory Guide RG 1.121 has been appropriately incorporated into the steam 5.4.2.2-5 DRAFT Rev. 2 - April 1996 generator tube ISI program, particularly as it applies to determining the acceptable length of run time between steam generator tube inspections.32 4. For review of those ISI programs that accommodate a 24 month fuel cycle, the reviewer should consider the applicable staff positions provided in Generic Letter 91-04 (Reference 13).33 5. The staff has accepted alternative repair criteria applicable to outside diameter stress corrosion cracking (ODSCC) at the tube-to-tube support (TSP) plate intersections in Westinghouse-designed steam generators having drilled-hole tube support plates and alloy 600 steam generator
