port operation at power uprate conditions, and changes in plant operating parameters (such as reactor coolant temperature, pressure, T,,,, reactor pressure, flow, etc.) resulting from operation at EPU conditions. The reviewer should assess if the licensee adequately identified functions important to safety that are affected by EPU-related modifications, setpoint adjustments, and changes in plant operating parameters. In particular, the licensee should have considered the safety impact of first of-a-kind plant modifications, the introduction of new system dependencies or interactions, and changes in system response to initiating events. The review scope can be limited to those functions important to safety associated with the anticipated operational occurrences described in Attachment 2 to this SRP, "Transient Testing Applicable to Extended Power Uprates." To assist in this review, Attachment 2 also includes typical transient testing acceptance criteria and functions important to-safety associated with these anticipated events. The reviewer should verify that the proposed EPU test program adequately demonstrates each function important to safety that meets all of the following criteria: (1) is impacted by EPU-related modifications, (2) is required to mitigate a plant transient listed in Attachment 2, and (3) involves the integrated response of multiple SSCs. If a function important to safety cannot be adequately tested by overlapping individual component- or system-level tests, the licensee should propose suitable system functional testing. C. Use of Evaluation To Justify Elimination of Power-Ascension Tests 1. General Discussion In certain cases, the licensee may propose an EPU test program that does not include all of the power-ascension testing that would normally be required by the review criteria of Sections III.A and lII.B above. The licensee shall provide an adequate justification for each of these normally required power-ascension tests that are not included
