de Containment." It has been demonstrated by testing that the reactor coolant pumps will withstand a complete loss of cooling water for 20 minutes, and instrumentation in accordance with IEEE 279 that alarms in the control room is provided to detect a loss of cooling water to ensure a period of 20 minutes is available so that the operator would have sufficient time to initiate manual protection of the plant. Alternatively, if it is not demonstrated by the necessary pump 9.2.2-4 Rev. 3 - June 1986 testing that the reactor coolant pumps will operate for 20 minutes without operator corrective action. 1. Instrumentation in accordance with IEEE 279 is provided consist- ent with the criteria for the protection system to initiate automatic protection of the plant upon loss of cooling water to a pump. For this case, the component cooling water supply to the seal and bearing of the pump may be designed to nonseismic Category I requirements and Quality Group D, or 2. The component cooling water supply to each pump is designed to be capable of withstanding a single active failure or a moderate- energy line crack as defined in Branch Technical Position ASB 3-1 and to seismic Category I, Quality Group C, and ASME Section III Class 3 requirements. 5. General Design Criterion 45, as related to the design provisions to permit inservice inspection of safety-related components and equipment. 6. General Design Criterion 46, as related to the design provisions to permit operational functional testing of safety-related systems or components to ensure. a. Structural integrity and system leak tightness. b. Operability and adequate performance of active system components. c. Capability of the integrated system to perform required functions during normal, shutdown, and accident situations. III. REVIEW PROCEDURES The procedures set forth below are used during the construction permit (CP) application review to determine that the design criteria and bases and the pre- liminary design as set
