ncy to satisfy the single failure criterion. 5.4.6-10 Revision 2 - March 2007 7. The reviewer contacts the Instrumentation and Electrical Control Systems organization to ascertain that the RCIC system operation is not dependent on ac power sources, that battery capability is sufficient to permit operation of the RCIC system for a period of 2 hours without the availability of ac power, and that the RCIC pump room coolers meet the power supply guidance of task action plan item II.K.3.24 of NUREG-0737. 8. The reviewer checks with the Mechanical Engineering organization to verify that essential RCIC system components are designated as seismic Category I. 9. The reviewer contacts the Quality Assurance organization to verify that the applicant’s proposed preoperational and initial startup test programs comply with Regulatory Guide 1.68. At the COL stage, the reviewer confirms with Quality Assurance that the applicant provided sufficient information to identify the test objectives, methods of testing, and test acceptance criteria (see Positions C.2, C.3, and C.4 of Regulatory Guide 1.68). Quality Assurance 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 designs are 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 design differs significantly from previously reviewed designs, the review of the impact of the proposed changes on the required preoperational and initial startup testing programs occurs at the construction permit stage. This effort should particularly evaluate the need for any special design features required to perform acceptable test programs. 10. The Technical Specifications organization is
