CFR Title: 

Content:
valves and the suppression pool cooling mode of the residual heat removal system, have been found capable of removing 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 has been found to be available even with a loss of offsite power and with a single active failure. The capability and capacity of the RCIC system is sufficient with respect to the plant's ability to cope with, and recover from, an SBO of a specified duration by determining compliance with Regulatory Guide 1.155 positions C.3.2, C.3.3, and C.3.5 as related to the design of the RCIC system. Conformance with 10 CFR 50.63 for station blackout is discussed in Section 8.4 of this report.114 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, analysis, and acceptance criteria (ITAAC), including design acceptance criteria (DAC), site interface requirements, and combined license action items that are relevant to this SRP Section.115 V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP Section. This SRP section will be used by the staff when performing safety evaluations of license applications submitted by applicants pursuant to 10 CFR 50 or 10 CFR 52. Except in 116 those cases in which the applicant proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described herein will be used by the staff in its evaluation of conformance with Commission regulations. The provisions of this SRP section apply to reviews of applications docketed six months or more after the date of issuance of this SRP section.117 5.4.6-15 DRAFT Rev. 4 - April 1996
