entation. V. RISK-INFORMED IST PROGRAM DOCUMENTATION The reviewer should examine the licensee's submittal to assure that it contained the documentation necessary to conduct the review described herein (i.e., the documentation described in Regulatory Position 4 of Regulatory Guide 1.175). The detailed RI-IST program and its updates should be maintained on site and should be available for NRC inspection consistent with the requirements of 10 CFR Part 50, Appendix B. The reviewer should also ensure that the cover letter that transmits to the licensee the staff's safety evaluation approving the proposed RI-IST program (i.e., alternate IST program to that prescribed by the ASME Code) contains a statement to the effect that "Failure to comply with the RW-IST program as reviewed and approved by the NRC staff and authorized pursuant to 10 CFR 50.55a(a)(3) (e.g., including scope, test strategy, documentation, and other programmatic requirements) constitutes noncompliance with 10 CFR 50.55a and is enforceable." VI. IMPLEMENTATION The preceding material is intended to provide guidance to licensees regarding the NRC staffs plans for using SRP Section 3.9.7. Except in those cases in which the applicant proposes an acceptable alternate method for complying with specified portions of Regulatory Guide 1.175, the method described herein will be used by the staff in its evaluation of risk-informed, performance-based changes to the design, operation, and other activities of the licensee's plant. 3.9.7-32 Rev. 0-August 1998 VII.
