tifications for proposed differences. B. Post Modification Testing Requirements for Functions Important to Safety Impacted by EPU-Related Plant Modifications 1. General Discussion EPUs usually require significant modifications to major balance-of-plant equipment, in addition to setpoint and operating parameter changes. Therefore, within its respective technical area, each secondary review branch will assess if the licensee adequately evaluated the aggregate impact of EPU plant modifications, setpoint adjustments, and parameter changes that could adversely impact the dynamic response of the plant to anticipated initiating events. The objective of this review is to verify that the licensee has proposed a testing program which demonstrates that EPU-related modifications to the facility have been adequately implemented. The reviewer is not expected to evaluate the specific component- and system-level testing requirements for each plant modification, parameter change, or setpoint adjustment. Based on previous experience, testing required by Technical Specifications and existing 10 CFR Part 50, Appendix B, quality assurance programs have been adequate to demonstrate individual system or component performance characteristics. Therefore, this review is intended to ensure that functions important to safety that rely on the integrated operation of multiple SSCs following an anticipated operational occurrence are adequately demonstrated prior to extended operation at the requested EPU power level. 2. Specific Acceptance Criteria Based on review of the licensee's EPU license amendment request, the reviewer will determine if the licensee has adequately identified the following: DRAFT Rev. 0 - December 2002 I 14.2.1-6 plant modifications and setpoint adjustments necessary to support 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
