ctual 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 ) systems to see that the systems 76 are physically separated and can function independently. 5. The reviewer examines the system design in SAR Section 5.4.6 to verify that the capability for automatic switchover of suction from the condensate storage tank to the suppression pool has been provided per the requirements of item II.K.3.22 of NUREGs-0737 and 0718 (Ref. 1 and 11) . The reviewer also judges whether adequate 77 control and monitoring information is available to allow the operator to actuate the system manually or to realign the RCIC system manually within the time allowed (i.e., change the RCIC system suction from the condensate storage tank to the suppression pool, or to the steam condensing mode of the residual heat removal system). 6. The reviewer contacts ICSB HICB to confirm that automatic actuation and 78 remote-manual valve controls are capable of performing the functions required and that sensor and monitoring provisions are adequate. The instrumentation and controls of the RCIC system, in conjunction with the HPCS, (or HPCI, or HPCF ) system are to have 79 sufficient redundancy to satisfy the single failure criterion. 7. The reviewer contacts PSB EELB to ascertain that the RCIC system operation is not 80 dependent on a-c power sources, and that there is sufficient battery capability to permit operation of the RCIC for a period of two hours without the availability of a-c power, and the RCIC pump room coolers meet the power supply requirements of Task Action Plan item II.K.3.24 of NUREG-0737.81 8. The reviewer checks with MEB EMEB to verify that essential RCIC system 82 components are designated seismic Category I. 9. The reviewer contacts PSRB HQMB to verify that the applicant's proposed 83 preoperational and initial startup test programs are in
