preoperational and initial startup tests. “Preoperational testing,” as used in this regulatory guide, consists of those tests conducted following completion of construction inspections and tests, but before fuel loading, to demonstrate, to the extent practical, the capability of SSCs to meet the performance requirements to satisfy the design criteria. Initial startup testing, as used in this regulatory guide, consists of equipment performance tests completed before, during, and after fuel loading. These performance tests are normally completed during pre-operational, fuel loading, pre-critical, initial criticality, low power, and power ascension test phases to confirm the design bases and demonstrate, to the extent practical, that the plant will operate in accordance with design and that it is capable of responding to anticipated transients and postulated accidents as specified in the FSAR. Section C.1.13.4 “Operational Program Implementation,” of RG 1.206 provides guidance on completion of ITP license conditions after the COL is issued. The OL and COL FSAR include this information to enable the NRC staff to perform inspections of ITP license conditions. After fuel load, licensees should implement operations, testing, maintenance, and monitoring of SSCs consistent with technical specifications (TS) and the requirements and guidance in 10 CFR 50.65, “Requirements for Monitoring the effectiveness of Maintenance at Nuclear Power Plants,” RG 1.160, “Monitoring the Effectiveness of Maintenance at Nuclear Power Plants,” (Ref. 6), and American Society of Mechanical Engineers (ASME) “Code for Operation and Maintenance of Nuclear Power Plants, (OM Code), Division 1, Section IST – Light Water Reactor Nuclear Power Plants,” (Ref. 7). The power ascension test phase of the ITP should be completed in an orderly and expeditious manner. Failure to complete the power ascension test phase within a reasonable time period may indicate inadequacies in the
