DESCRIPTION Relief is requested from stroke timing the High Pressure Coolant Injection (HPCI) drain pot solenoid valves.

SIZE CAT CLASS CORD 1"
B 2
51/C7 l"
B 2
374/C7 CODE REOUIREMENT(Sl FUNCTION HPCI Drain Pot Solenoid HPCI Drain Pot Solenoid IWV-3410 Valve exercising Test: Category A and B valves shall be exercised at least once every three months.
BASIS FOR RELIEF These solenoid valves are totally enclosed with no evidence of position indication available.
Therefore, no direct method of timing these valves exists.
These valves can be opened by a handswitch, and also periodically operate automatically during HPCI Surveillance tests. Although monitoring for degradation is not practicable, the valves can be determined to have stroked by functional testing.
ALTERNATE TEST Since there are no indicating lights or other evidence of position indication, these valves will be stroked quarterly without timing. On a refuel outage basis, the HPCI Drain Pot will be filled until the limits are reached and then observed to verify that the 2(3)-2301-32 valves adequately open to drain the water. In addition, as part of a preventive maintenance program, these valve assemblies will be replaced every third refuel outage.
