Applies to the operating status of the Reactor Applies to periodic testing requirements for

Depressurization System (RDS) and the attached the RDS and the attached mechanical snubbers.

Objective: Objective:

To assure the operability of the RDS and when To verify operability of the RDS.

working in conjunction with the emergency core cooling system to allow cooling of the reactor Specification:

fuel in the event of a Loss of Coolant Accident. ,

i A. The isolation valves shall be test-operated Specification: at least once every three months.

i A. The RDS shall be operable at all power B. The depressurizing valves shall be test-levels and when the reactor is critical operated during each cold shutdown; however, with the head on or when in hot shutdown in the case of frequent cold shutdowns, conditions. these valves need not be exercised more often than once every three months per B. The limiting conditiotis for operation of Section IWV-3410 Summer 19 the instrumentation and actuating circuitry ASMEB&PVCodeSectionXI.gAddendaofthe l, which initiates and controls the RDS are given in Table 3.5.2.h.- C. The instrumentation shall be functionally tested, calibrated and checked as-indicated Action: in Table 4.5.2.h.

1. Should one depressurizing valve or isolation valve become inoperable in the closed position, the reactor may remain in operation for a period not to exceed seven (7) days. The remaining valves and (1)For the duration of Cycle 23 operation, quarterly test operation (during cold shutdcvn) of the depressurizing valves is not required. In lieu of this surveillance testing requirement, full stroke exercise one depressurizing valve and partial stroku exercise the other three depressurizing valves during the refueling cutages prior to and following Cycle 23 operation. If no shutdowns occur during Cycle 23 operation, or if all four depressurizing valves are required to be partial stroke exercised for other reasons during Cycle 23 operation, continue this surveillance testing , variance throughout Cycle 24 operation.
