also includes the 73 proposed technical specifications, to assure that they are adequate in regard to limiting conditions of operation and periodic surveillance testing. Upon request from the primary reviewer, other branches will provide input for the areas of review stated in subsection I. The primary reviewer obtains and uses such input as required to assure that this review procedure is complete. 74 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 assure cladding integrity. This determination is based on engineering judgment and independent calculations (where deemed necessary), using information as specified in steps 2 and 3 below. The reviewer consults with the CPB to assure verifies that the decay heat loads used in the RCIC analyses are applicable, consistent with SRP Section 4.2, and suitably conservative. 75 2. Using the description given in Section 5.4.6 of the SAR, including component lists and performance specifications, the reviewer determines that the RCIC system piping and instrumentation are such as to allow the system to operate as intended. This is accomplished by reviewing the piping and instrumentation diagrams to confirm that piping arrangements permit the required flow paths to be achieved and that sufficient process sensors are available to measure and transmit required information. 3. Using the comparison tables of SAR Section 1.3, the RCIC system is compared to designs and capacities of such systems in similar plants to see that there are no DRAFT Rev. 4 - April 1996 5.4.6-10 unexplained departures from previously reviewed plants. Where possible, comparisons should be made with actual performance data from similar systems in operating plants. 4. The reviewer checks the piping and instrumentation diagrams and equipment layout drawings for the RCIC and HPCS, (or HPCI, or HPCF )
