. B. REVIEW OF IMPLEMENTATION, PERFORMANCE MONITORING, AND CORRECTIVE ACTION 1. Program Implementation The reviewer should check the adequacy of the justification for extending the test interval for a sample of low safety significant components to verify that the extension is appropriate. The test intervals for LSSC may be implemented at the discretion of the licensee after the NRC approves the RI-IST program. The reviewer should verify that the licensee is increasing the test interval for low safety significant components in a step-wise manner. Component corrective action procedures should be in place for LSSC being tested on a step-wise basis before any test intervals are extended. 3.9.7-24 Rev. 0-August 1998 HSSC and LSSC that will continue to be tested in accordance with the ASME Code requirements for the licensee's code of record, or ASME Code Cases that have been endorsed by the NRC, require no further review by the reviewer and are subject to site-specific inspections. The reviewer should verify that the licensee has developed plant corrective action and feedback procedures to ensure that testing failures are reevaluated for possible adjustment to the component's grouping and test strategy. 2. Performance Monitoring of IST Component The review procedures consist of the following steps: * The performance monitoring program is identified in the licensees proposal for RI-IST. * The program is reviewed to determine whether it contains a test program that will provide sufficient data to detect component degradation in a timely manner, as described in Section II.B.2. The reviewer should determine whether the licensee's monitoring process for RI-IST is coordinated with existing programs for monitoring components performance and other operating experience on their site and, when appropriate, throughout the industry. In particular, monitoring that is performed as part of the Maintenance Rule (10 CFR Part 50.65) implementation can be used in the RI-IST program when the
