, FUNCTION: Maintains minimum flow for Auxiliary Feedwater Pumps.

TEST REQUIREMENT: Full stroke exercise and stroke time quarterly BASIS FOR RELIEF: This valve automatically regulates to maintain the minimum flow through the pump by monitoring the flow on the suction of the pump. There are not sufficient manual controls on this valve to permit the desired testing.

I These valves will operate during testing of the pump and '

] their operability will be verified then.

TEST REQUIREMElfr: Full stroke exercise quarterly '

BASIS FOR RELIZF: Flow cannot be put through these valves because this would contaminate the aux. feed system with raw water.

ALTERNATE TESTING: At least one of these two valves will be disassembled and full stroked during each refueling outage, and both valves will have been disassembled and full stroked after 4 two consecutive refueling outages. Failure of one valve to properly full stroke during a refueling outage will result in the remaining valve being disassembled and full stroked during that outage.

TEST REQUIREMENT: Cycle and time every three months.

BASIS FOR RELIEF: Closure of one of these valves during unit operation would inhibit normal seal water flow across the reactor coolant pump number 1 seal. This action could result in damage to the reactor coolant pump seals or the pumps themselves.

Opens on flow from the Centrifugal Charging Pump (s).

TEST REQUIREMENT: Verify proper valve movement every three months.

BASIS FOR RELIEF: Valve cannot be full or partial stroke exercised during power operation or cold shutdown because this would result in an increase in the RCS boron inventory and could result in a plant shutdown.

Full stroke exercising during cold shutdown could result in a low temp. overpressurization of the RCS.

ALTERNATE TESTING: Valve will be full stroked during refueling.

O MC-2554-3.1 VALVE: 2NV-223 CATEGORY. C CLASS: B FUNCTION: Opens on flow alignment from FWST.

TEST REQUIREMENT: Verify proper valve movement every three months.

BASIS FOR RELIEF: Testing of this valve requires opening 2NV-221A or 2NV-2228. Failure of one of these valves in the open position aligns the FWST to the suction of the charging pumps with no mea,s of isolating the flow path. This would result in at increase in boron inventory in the RCS and could result in a plant shutdown. Full stroke 5l exercising or partial stroke exercising at cold shutdown l could result in a low temperature overpressurization.

5 ALTERNATE TESTING: Valve will be full stroked during refueling.

, The rest of the VP valves may not be opened at all during power operation.

ALTERNATE TESTING

Valves will be timed whenever the system is operated or l

whenever the valves are cycled, and the elapsed time since -l j

the previous test'has been.three months or greater. If the valves are operating in a mode where the containment timing spec (T.S. 3.6.l.9) does not apply and are returned to the i 5 closed position prior to a mode where the containment timing spec applies, then timing-the valves after operation will-j not be required.

TEST REQUIREMENT: Full stroke exercise quarterly.

BASIS FOR RELIEF: 2FW-28 cannot be full stroked during power operation since the only full flow path is into the'RCS by the Residual Heat Removal Pumps (ND). The ND Pumps cannot overcome RCS pressure.

' ALTERNATE TESTING: Valve will be full stroke exercised at refueling and partial stroked quarterly.

TEST REQUIREMENT: Verify proper valve movement every three months.

BASIS FOR RELIEF: These valves have been provided with an interlock which prevents their opening when the Reactor Coolant System pressure is greater than 385 psig.

ALTERNATE TESTING: Valve will be cycled during cold shutdowns.

BASIS FOR RELIEF: 2ND-70 cannot be full stroked during power operation or cold shutdown since the only full flow path is into

TEST REQUIkEMENT: Cycle valve every three months.

BASIS FOR RELIEF: Due to interlocks in the Safety Injection System and the actual Residual Heat Removal System design, it is impossible to test these valves without rendering both trains of Residual Heat Removal and both trains of Safety Injection inoperable during operation.

VALVE: 2ND-71 CATEGORY: C CLASS: B FUNCTION: RHR to SI Suction Check.

TEST REQUIREMENT: Full stroke exercise quarterly.

BASIS FOR RELIEF: Valve cannot be full stroked at power since the only full flow path is into the RCS and this can only be done with the reactor head removed at refueling.

2ND-71 cannot be partial stroked during power since the required valve lineup would render both trains of safety injection inoperable. During cold shutdown, both SI pumps are tagged out to prevent a low tempera-ture overpressurization.

VALVE: 2NI-180, 2NI-181, 2NI-175, 2NI-176 CATEGORY: A, C CLASS: A FUNCTION: Opens on flow from the ND or NI to NC System.

1 TEST REQUIREMENT: Verify valve opens on flow from NI or ND System to the NC System once per three months.

BASIS FOR RELIEF: The discharge pressure of the NI and ND Pumps is not l sufficient for opening the valve to the Reactor Coolant 1 System during power operation. '

ALTERNATE TESTING: Valve will be tested for proper movement during cold shutdowns, but not more often than once per nine months.

O MC-2563-3.1 5l VALVE: 2NI-1848, 2NI-185A l CATEGORY: B CLASS: B FUNCTION: Isolate the containment sump (2NI-184 isolates train B, 2NI-185 isolates train A). These valves also provide an alternate source for suction to the Residual Heat Removal Pumps.

BASIS FOR RELIEF: Due to interlocks in the Safety Injection System and the actual Residual Heat Removal design, it is impossible to test these valves without rendering both trains of Residual Heat Removal and both trains of Safety Injection inoperable. During cold shutdowns, the RHR pumps are required for decay heat removal.

ALTERNATE TESTING: Full stroke exercise during refueling.
