REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. 5.4.6-9 Revision 2 - March 2007 These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. The COL and design certification (DC) reviews also include the proposed technical specifications to ensure that they are adequate in regard to limiting conditions of operation and periodic surveillance testing. Upon request from the primary reviewer, other reviewers will provide input for the areas of review as noted in subsection I. The primary reviewer obtains and uses such input as necessary to ensure that this review is complete, including the following activities: 1. Using the RCIC operating requirements specified in SAR Section 5.4.6 and Chapter 15, the reviewer confirms that the RCIC system can maintain coolant inventory in the reactor vessel to keep the core covered and ensure cladding integrity. This determination is based on engineering judgment and independent calculations (as necessary), using the information specified in items 2 and 3 below. The reviewer verifies that the decay heat loads used in the RCIC analyses are applicable, consistent with SRP Section 4.2, and suitably conservative. 2. Using the description in Section 5.4.6 of the SAR, including component lists and performance specifications, the reviewer determines whether the RCIC system piping and instrumentation will allow the system to operate as intended. This is accomplished by reviewing the piping and instrumentation diagrams to confirm that piping arrangements permit achievement of the required flowpaths and that sufficient process sensors are
