king process categorized as being highly safety significant (HSSC). The method used by the licensee to categorize components should be described. There should also be a detailed description of how the proposed RI-IST program affects the design, operation, and other activities at the plant and why these proposed changes are acceptable. If exemptions from specific regulations, technical specification amendments, or relief requests are required to implement the licensee's proposed RI-IST program, the appropriate requests should accompany the licensee's submittal. Revisions to testing schedules and methods should be described. The implementation and monitoring approach should be included. Details of the RI- IST implementation plans and schedules should be available onsite for inspection. The licensee should also have described the proposed IST program change in terms of how it conforms to the objectives of the Commission's PRA Policy Statement, concerning enhanced decisionmaking, more efficient use of resources, and reduction of unnecessary burden. The description may consider such benefits from the change as reduced fiscal and personnel resources and reduced radiation exposure, as well as increased reactor safety. 3.9.7-2 Rev. 0-August 1998 The reviewer should become familiar with the licensee's entire submittal before beginning the detailed review described in the sections that follow. In short, the reviewer should develop an understanding of the proposed change in terms of: * the particular components that would be affected by proposed changes to the IST program * the plant systems involved with the proposed changes * the change in testing strategy (i.e., test frequency and methods) proposed for each component or group of components * the affect of proposed changes on plant design, operation, and other activities * the affect of proposed changes on the defense in depth philosophy and safety margins * the effect of the changed testing strategy on overall plant risk *
