ements permit the required flowpaths to be achieved and that sufficient process sensors are available to measure and transmit necessary information. 5.4.13-12 March 2007 3. Using the comparison tables in the applicant’s DCD, where applicable, the reviewer compares the ICS to the designs and capacities of such systems in similar plants to determine 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 examines the P&IDs and equipment layout drawings for the ICS and redundant or backup systems (RWCU/SDC, ADS, PCCS, and GDCS) to ensure that the systems are physically separated and can function independently. 5. The review determines whether adequate control and monitoring information is available to allow the operator to actuate the system manually within allowable time. 6. The reviewer shall 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 ICS and redundant or backup systems (RWCU/SDC, ADS, PCCS, and GDCS) have sufficient redundancy to satisfy the single failure criterion. 7. The reviewer ascertains that ICS operation is not dependent on ac power sources, and that sufficient battery capacity exists to permit operation of the ICS for the period needed without the availability of ac power. 8. The reviewer verifies that essential ICS components are designated seismic Category I. 9. The reviewer verifies that the applicant's proposed preoperational and initial startup test programs are in accordance with the guidance of Regulatory Guide 1.68. At the COL stage, the reviewer confirms that the applicant has 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
