August 2006 A. Comparison of Proposed EPU Test Program to the Initial Plant Test Program 1. General Discussion The licensee should compare the proposed EPU testing program to the original test program carried out during initial plant licensing. The scope of this comparison should include (1) all initial power ascension tests performed at a power level of equal to or greater than 80 percent of the original licensed thermal power level; and (2) initial power ascension tests that were performed at lower power levels if the EPU would invalidate the test results. The licensee should either repeat the initial power ascension tests within the scope of this comparison or provide justification for deviations that are proposed. 2. Specific Acceptance Criteria The primary reviewer, with assistance as necessary from the secondary review branches, will determine if the licensee has adequately identified the following in the EPU LAR: • all initial power ascension tests performed at a power level of equal to or greater than 80 percent of the original licensed thermal power level; • all initial test program tests performed at power levels lower than 80 percent of the original licensed thermal power level that would be invalidated by the EPU; and, • differences between the proposed EPU test program and the portions of the initial test program identified by the previous criteria. The reviewer should refer to the plant-specific testing identified in FSAR Chapter 14.2, “Initial Plant Test Program” (or the equivalent FSAR section for nonstandard format plants), and startup test reports, if available, to verify that the licensee has adequately identified the scope of the initial plant test program. Additionally, Table 1, “Typical Steady-State Power Ascension Testing Applicable to Extended Power Uprates,” and Table 2, “Typical Transient Testing Applicable to Extended Power Uprates,” to this SRP section provide a generic summary of power ascension tests typically
