Content:
10 CFR 50.62 with respect to seismic design, reactivity control system redundancy, and 44 reactivity control system capability. This conclusion is based on the following: 1. The applicant has met the requirements of General Design Criterion 2 with respect to seismic design by meeting regulatory position C-1 of Regulatory Guide 1.29. 2. The applicant has met the requirements of General Design Criterion 26 with respect to the redundancy of reactivity control systems by providing two independent reactivity control systems of different design principles and with respect to the capability of holding the reactor core subcritical under cold conditions. 3. The applicant has met the requirements of General Design Criterion 27 with respect to the combined capabilities of the reactivity control systems to reliably control reactivity changes under postulated accident conditions since the SLCS has the capability to shut down the reactor with all control rods withdrawn, assuming a single failure. 4. The applicant has met the requirements of 10 CFR Part 50, §50.62(c)(4) by providing a reliable SLCS having the capability of injecting a borated water solution into the reactor pressure vessel that meets, or exceeds, the reactivity control requirements specified in the rule. Where applicable, also include the following: The applicant has also provided a system with acceptable provisions for automatic initiation.45 Where applicable, for designs incorporating motor-operated SLCS storage tank discharge valves, the following conclusion should also be included: 5. The applicant has acceptably incorporated the SLCS storage tank discharge valves into a Reliability Assurance Program.46 9.3.5-11 DRAFT Rev. 3 - April 1996 For design certification reviews, the findings will also summarize, to the extent that the review is not discussed in other safety evaluation report sections, the staff's evaluation of inspections, tests, analyses, and acceptance criteria (ITAAC), including design acceptance
