a and design bases for the ICS, analysis of the adequacy of the criteria and bases, and the conformance of the design to these criteria and bases. 5.4.13-15 March 2007 The staff concludes that the ICS is acceptable and meets the requirements of GDC 2, 4, 5, 17, 33, 34, 35, 36, 37, 54, 10 CFR 50.46, 10 CFR 50.63, 10 CFR 52.47(a)(1)(vi), and 10 CFR 52.97(b)(1). This conclusion is based on the following: 1. The applicant has met the requirements of (cite Reg.) with respect to (state limits of review) in the following manner: (as an example, use one or more of the following as applicable) A. Meeting the regulatory position in Regulatory Guide ________. B. Providing and meeting an alternative method to the regulatory position in Regulatory Guide ________ that the staff has reviewed and found to be acceptable. C. Meeting the regulatory position in BTP ________. D. The calculational method used by the applicant for (state) has been previously reviewed by the staff and found acceptable; the staff has reviewed the key parameters in this case and found them to be acceptable. E. The applicant has met the requirements of (industry standard—number and title) that has been reviewed by the staff and determined to be appropriate for this application. Repeat the above discussion for each requirement listed in Subsection II.1 - II.12. 2. The staff concludes that the ICS and redundant or backup systems (RWCU/SDC, ADS, PCCS, and GDCS) are found capable of removing core decay heat following reactor shutdown and isolation so that sufficient coolant inventory is maintained in the reactor vessel to keep the core covered and ensure cladding integrity. The staff concludes that this capability is available even with a LOOP and with a single active failure. The capability and capacity of the ICS are sufficient with respect to the plant’s ability to cope with, and recover from, an SBO of a specified duration by determining adherence with Regulatory Guide 1.155, Positions C.3.2, C.3.3, and
