ner which minimizes operational reliance on untested SSCs or safety functions. III. REVIEW PROCEDURES The purpose of this review is to obtain reasonable assurance that the proposed EPU testing program adequately controls the initial power ascension to the proposed EPU power level. The EPU test program should include steady-state and transient performance testing sufficient to demonstrate, in conjunction with plant operating experience, computer modeling, and analyses, that SSCs will perform satisfactorily at the requested power level. The proposed EPU test program should be based on a systematic review of the initial plant test program to identify initial licensing power ascension testing that may be invalidated by the requested EPU. Additionally, the EPU test program should include appropriate testing to demonstrate that EPU-related plant modifications have been adequately implemented. Specific guidance1 for assessing licensees’ justifications for not performing certain tests, including large transient tests, is provided in Section III.C below.
