Due to the similar function of these valves, the conditions observed during Alternate Testing of one valve will be representative of the others. Performing the Alternata Testing on as valves is a hardship which is not compensated for by an incnaamd level of quality or safay, l4 i

[ ALTERNATE TESTING: Verify operability of the valves by partially disassembling, manually esercising and visually inspecting the internals of one of the valves at each refueling outage on an alternating schedule. If this valve is found to be inoperable then the other valvas will be disassembled and inspected before any valve will be declared operable.

During cold shutdown, full or partal stroke exercising these valves could result in a low temperature overpreuuritation of the reactor coolant system which would exceed the design limitation of the system and adversely affect plant safety.

diseasombled and inspected before any of the four can be declared operable. Upon completion of the disassembly cycle for these four check valves, k will be evaluated if a modified inspection cycle is appropriate based on inspection resulte and WOO experience. This le considered appropriate due to the location of these valves in a high radiation area.

Check valve operabdity,in this case, is demonstrued by ,trification of the required minimum now delivered to the stearn generator, it is recogniud that these check valves perform their closed safety function in series with other system check balves (ie. pump discharge check valves). Thus, aduional testiny is performed during cold shutdowns to demonstras closure individually, The check valves are isolated uparsam and downstream and a reverse differential pressure is impressed across the valve through a tan connection. Subsequendy, an upstrearn vent is_ opened and a leakage observation is a ede to em valve closure. Further, i l when the plant is at power, the closure of the check valves is monitored continuously.
