riate for this application. 2. Repeat the above discussion for each GDC listed. In addition, SRP Section 6.2 discusses conformance with GDC 55, 56, and 57 regarding containment isolation. Sections 3.3 through 3.6 of this report discuss conformance with GDC 2 and 4 for protection against natural phenomena, environmental hazards, and potential missiles. The RCIC system and HPCS (or HPCI) system, in conjunction with the SRVs and the suppression pool cooling mode of the RHR system, have removed core decay heat following feedwater system isolation and reactor shutdown so that sufficient coolant inventory is maintained in the reactor vessel to keep the core covered and ensure cladding integrity. This capability was available even with a loss of offsite power and with a single active failure. The capability and capacity of the RCIC system are sufficient with respect to the plant’s ability to cope with, and recover from, an SBO of a specified duration by complying with the guidance set forth in Positions C.3.2, C.3.3, and C.3.5 of Regulatory Guide 1.155, as they relate to the design of the RCIC system. SRP Section 8.4 discusses conformance with 10 CFR 50.63 for SBOs. For DC and COL reviews, the findings will also summarize the staff’s evaluation of requirements and restrictions (e.g., interface requirements and site parameters) and COL action items relevant to this SRP section. In addition, to the extent that the review is not discussed in other SER sections, the findings will summarize the staff's evaluation of the ITAAC, including design acceptance criteria, as applicable. V. IMPLEMENTATION The staff will use this SRP section in performing safety evaluations of DC applications and license applications submitted by applicants pursuant to 10 CFR Part 50 or 10 CFR Part 52. Except when the applicant proposes an acceptable alternative method for complying with specified portions of the Commission’s regulations, the staff will use the method described herein to evaluate
