and that testing activities are conducted in a manner which minimizes operational reliance on untested safety functions. Regulatory Guide (RG) 1.68, “Initial Test Programs for Water-Cooled Nuclear Power Plants,” Revision 2, describes the general scope and depth of initial test programs that the NRC staff found acceptable during the review of original operating license applications. The SSCs subject to initial testing performed safety functions that included fission product containment; reactivity monitoring and control reactor safe shutdown (including maintaining safe shutdown) core cooling accident prevention and consequence mitigation as specified in the design and credited in safety analyses. C. 10 CFR 50.34(b)(6)(iii) requires that each application for a license to operate a facility include in the FSAR plans for preoperational testing and initial operations. The initial test program (which includes preoperational testing and testing during initial operation) verifies that SSCs are capable of performing their safety functions as specified in the design and credited in safety analyses. Application of 10 CFR 50.34(b)(6)(iii) to the EPU test program ensures that the licensee submits adequate information, commitments, and plans demonstrating that the proposed EPU does not invalidate the testing provisions for the original design basis. The preoperational testing and the initial startup testing invalidated by the requested increase in power level are evaluated and repeated as necessary to demonstrate that SSCs are capable of performing their safety functions. This provides assurance that operation at the requested higher power level will be within the bounds of the design and safety analyses and that EPU testing activities will be conducted in a sequence and manner 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
