itutes an acceptable basis for meeting, in part, the inservice inspection requirements of General Design Criterion 32. Specific acceptance criteria for meeting the inservice inspection requirements of General Design Criterion 32 and 10 CFR 50.55a are listed below: 14 5.4.2.2-3 DRAFT Rev. 2 - April 1996 1. 10 CFR 50.55a(b)(2)(iii) specifically addresses steam generator tubes and states that if the plant Technical Specifications include inspection requirements different than those in Article IWB-2000 in Section XI of the ASME Code, the Technical Specifications govern.15 2. The guidelines for periodic inspection and testing of the steam generator tube portion of 16 the reactor coolant pressure boundary are specified in Regulatory Guide 1.83 and the 17 applicable Standard Technical Specifications, NUREG-0103, 0212, or 0452 (References 5 through 7 and 9 through 11). For applicants referencing a certified design, the 18 Standard Technical Specifications associated with the referenced design will specify the guidelines for periodic inspection and testing of the steam generator tube portion of the reactor coolant pressure boundary. The design of the steam generators to provide 19 access for an inservice inspection (ISI) program, and the proposed ISI program should 20 follow the recommendations given in Regulatory Guide 1.83. The steam generators should be designed to permit inspection of every tube. The tube examination equipment and procedures should be capable of detecting and locating defects with a penetration of 20% or more of the wall thickness. A permanent record of test data should be 21 provided. A baseline tube inspection should be scheduled prior to startup. The sample selection and testing of tubes, the inspection intervals, the actions to be taken if defects are identified, and reporting requirements should follow the recommendations in the applicable Standard Technical Specifications. 3. Regulatory Guide RG 1.121 provides guidance on minimum acceptable tube
