ither reperform initial power-ascension tests within the scope of this comparison or adequately justify proposed deviations. 2. Specific Acceptance Criteria Within its associated technical discipline, each secondary branch reviewer will determine if the licensee has adequately identified the following in the EPU license amendment request: * All power-ascension tests initially performed at a power level of equal to or greater than 80 percent of the original licensed thermal power level. All initial power-ascension tests performed at power levels lower than 80 percent of the original licensed thermal power level that would be invalidated by the EPU. Differences between the proposed EPU power-ascension test program and the portions of the initial power-ascension program included within the scope of this comparison. DRAFT Rev. 0 - December 2002 14.2.1-5 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 non standard 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, Attachment 1, "Steady-State Power Ascension Testing Applicable to Extended Power Uprates," and Attachment 2, "Transient Testing Applicable to Extended Power Uprates," to this SRP section provide a generic summary of power-ascension tests performed at or near full power. If the licensee's proposed EPU test program does not include performance of testing originally performed during the initial plant test program, the reviewer shall ensure that the licensee adequately justifies all differences. The reviewer should refer to Section Ill.C, below, for guidance on assessing the adequacy of justifications for proposed differences. B.
