it 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 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) systems to see that the systems 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 conden- sate 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 control and monitoring infor- 5.4.6-5 Rev. 3 - April 1984 mation 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 to confirm that automatic actuation and 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) system are to have sufficient redundancy to satisfy the single failure criterion. 7. The reviewer contacts PSB to ascertain that the RCIC system operation is not 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. 8. The reviewer checks with MEB to verify that essential RCIC system components are designated seismic
