r ITAAC, see RG 1.215, “Guidance for ITAAC Closure under 10 CFR Part 52," (Ref. 5). As part of the regulations in 10 CFR 50.34(b)(6)(iii) and 52.79(a)(28) for the ITP, the OL or COL applicant should describe in the FSAR the major phases of the ITP and the specific objectives to be achieved for each major phase. The descriptions and objectives of these test phases should be demonstrated to be consistent with the general guidelines and applicable regulatory positions contained in this regulatory guide, or justifications should be provided for any exceptions. Some safety-significant design requirements cannot be verified by ITAAC because the testing can only be done after fuel load. For example; testing of the main steam isolation valves at high flow conditions, testing involving 100 percent load rejection from the turbine, or verification of fuel and control rod performance cannot be verified by ITAAC. These requirements and supporting analyses for these tests should be identified in the applicable sections of the design certification documents or Section 14.2 of the COL FSAR. DG-1259, Page 3 While regulations require all SSCs important to safety be tested, all of them need not be tested to the same stringent requirements. Specifically, GDC 1, “Quality Standards and Records,” of Appendix A to 10 CFR Part 50 requires, in part, that SSCs important to safety shall be tested to quality standards commensurate with the importance of the safety functions to be performed. Criterion II of Appendix B to 10 CFR Part 50 also includes a graded approach to providing controls over activities affecting the quality of SSCs consistent with their importance to safety. Accordingly, the administrative requirements that govern the conduct of the test program (e.g., test program objectives, organizational elements, personnel qualifications, evaluation and approval of test results, and test records retention) contain provisions for the application of such administrative controls in a
