Content:
- April 1996 5.4.2.2-4 methodology, the method of inspection, the acceptance criteria for various types and sizes of flaws identified during the inspection, and various other related technical details required for properly performing the required inservice inspection activity. The steam generator tubes are accessible for eddy-current testing (ECT). The technical specifications and ASME Code, Section XI, provide requirements for steam generator tube inspection and repair. Steam generator tube inspection has been considered as a subissue of a number of generic safety issues, including Unresolved Safety Issues A-3, A-4 and A-5, and Generic Issues 67 and 135. Staff recommendations have been developed as part of an integrated program for the resolution of steam generator tube integrity issues. These recommendations, which include recommendations related to steam generator tube inspection programs, are described in Generic Letter 85-02 and in NUREG-0844, "NRC Integrated Program for the Resolution of Unresolved Safety Issues A-3, A-4 and A-5 Regarding Steam Generator Tube Integrity." Regulatory Guide 1.83 describes methods acceptable to the NRC staff for compliance with 10 CFR 50.55a. This Guide and the Standard Technical Specifications provide a comprehensive outline of ISI guidelines. Regulatory Guide 1.121 provides guidance for plugging of degraded tubes. Following the guidance of Regulatory Guides 1.83 and 1.121, and compliance with the requirements set forth in the technical specifications and 10 CFR 50.55a provide assurance that degradation of steam generator tubes will be detected and the integrity of the RCPB maintained. III. REVIEW PROCEDURES The reviewer will select and emphasize material from the procedures described below, as may be appropriate for a particular 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
