d be followed for the review of ITAAC. The review of ITAAC cannot be completed until after the completion of this section. IV. EVALUATION FINDINGS The reviewer verifies that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the following type to be included in the staff’s safety evaluation report. The reviewer also states the bases for those conclusions. 1. The SLCS includes storage tanks, accumulators, pumps, valves, and piping to the point where the system connects to the reactor coolant boundary. The SLCS, which is provided in BWRs only, provides reactivity control in the event the control rods cannot be inserted. The staff review will find the SLCS acceptable if the applicant’s design and design criteria conform to the Commission’s regulations, as set forth in the GDC and the applicable sections of 10 CFR 50.62, and to the positions of applicable regulatory guides, staff technical positions, and industry standards. 2. The staff reviewers conclude that the design of the SLCS is acceptable and conforms to the requirements of GDC 2, 4, 5, 26, and 27 and the applicable sections of 10 CFR 50.62 with respect to seismic design, reactivity control system redundancy, and reactivity control system capability. This conclusion is based on the following: 9.3.5-11 Revision 3 - March 2007 A. The applicant has met the requirements of GDC 2 with respect to seismic design by meeting Position C-1 of Regulatory Guide 1.29. B. The applicant has met the requirement of GDC 4 with respect to the dynamic effects associated with flow instabilities and loads. C. The applicant has met the requirements of GDC 5 with respect to structures, systems, and components important to safety not being shared among nuclear power units unless it can be demonstrated that sharing will not impair their ability to perform their safety function. D. The applicant has met the requirements of GDC 26 with respect to the redundancy
