Content:
August 2006 changes in plant operating parameters. In particular, the licensee should have considered the impact of first-of-a-kind plant modifications, the introduction of new system dependencies or interactions, and changes the effects of the steady-state and transient plant response have on the capability of SSCs important to safety to perform their specified functions. To assist in this review, Table 2 lists general acceptance criteria for transient testing for typical anticipated operational occurrences. The reviewer should verify that the proposed EPU test program adequately demonstrates the performance of SSCs important to safety that meet any of the following criteria: (1) the performance of the SSC is impacted by EPU-related modifications, (2) the SSC is used to mitigate an anticipated operational occurrence described in the plant-specific design basis, and (3) performance of the SSC can be affected by integrated plant operation or transient conditions. Important to safety SSCs that meet any of these criteria should be subject to appropriate testing requirements in the EPU test program to confirm that the SSCs will continue to function in accordance with their design criteria during steady-state and transient operating conditions, adequately tested by overlapping individual component-or system-level tests, or adequately justified as an exception to testing in accordance with the provisions discussed in Section III.C. C. Justification for Eliminating EPU Power ascension Tests 1. General Discussion The licensee may establish a test program that does not include some or all of the tests referred to above in Sections III.A and III.B that would normally be performed, provided that proposed exceptions are adequately justified in accordance with the criteria provided in Section III.C.2. Each secondary review branch will verify and document the adequacy of the licensee’s justification for test exceptions that are within the branch’s technical area of review. 2.
