to permit operation of the RCIC for a period of two hours without the availability of a-c power. 8. The reviewer checks with MEB to verify that essential RCIC system components are designated seismic Category I. 9. The reviewer contacts PSRB to verify that the applicant's proposed preoperational and initial startup test programs are in compliance with Regulatory Guide 1.68 (Ref. 10). At the OL stage, the reviewer confirms with PSRB that sufficient information is provided by the applicant to identify the test objectives, methods of testing, and test acceptance criteria (see par. C.2.b of Regulatory Guide 1.68). PSRB also verifies that the proposed test programs will provide reasonable assurance that the RCIC system will perform its safety function. As an alternative to this detailed evaluation, the reviewer may compare the RCIC system design to that of previously reviewed plants. If the design is essentially identical and if the proposed test programs are essentially the-same, the reviewer may conclude that the proposed test programs are adequate for the RCIC system. If the RCIC system differs significantly from that of previously reviewed designs, the impact of the proposed changes on the required preoperational and initial startup testing programs are reviewed at the CP stage. This effort should particularly evaluate the need for any special design features required to perform acceptable test programs. 10. The SSPB is contacted in regard to the proposed plant technical specifications to: a. Confirm the suitability of the limiting conditions of operation, including the proposed time limits and reactor operating restrictions for periods when system equipment is inoperable due to repairs and maintenance. b. Verify that the frequency and scope of periodic surveillance testing is adequate. 11. The reviewer confirms that the RCIC is housed in a structure whose design and design criteria have been reviewed by other branches (i.e., ASB, SGEB, MEB) to assure that it
