3.1.42 Test Requirement IWV-3520(2) requires that confirmation that the disk moves away from the seat shall be by visual observation, by electrical signal, by appropriate pressure indications, or by other positive means.
3.1.42.1 Basis for Relief Due to plant design, the operability of this normally closed check valve cannot be determined by any of the specific methods allowed in IWV-3520(2).
3.1.42.2 Alternate Testing The only positive means of demonstrating operability is by verification of flow such that the valve is full-stroke exercised. A flow greater than or equal to the manufacturer's minimum full-open value (Flow > 70 GPM) will be verified quarterly provided the associated charging pump is operable.
3.1.43 Test Requirement IWV-3520(2) requires that confirmation that the disk moves away from the seat shall be by visual cbservation, by electrical signal, by appropriate pressure indications, or by other positive means.
3.1.43.1 Basis for Relief Due to plant design, the operability of this normally closed check valve i
cannot be determined by any of the specific methods allowed in IWV-3520(2).
3.1.43.2 Alternate Testing The only positive means of demonstrating operability is by verification of flow such that the valve moves to perform its function.
A partial-stroke test will be accomplished during the quarterly testing of the TDA;W pump.
Acceptance of the pump test will provide assurance that the valve has par-tially opened.
A full-stroke test will be accomplished by providing AFW sys-2 tem design flow into the Steam Generators during a mode of operation approach-ing or leaving cold shutdown in which steam is available.
Verification of this flow in conjunction with verification that the control valve position i s a same for each test will provide assurance that the valve has opened iciently to perform its function.
4.1.44 Test Requirement Sub-Article IWV-3520(2) requires that the differential pressure for equivalent flow be no greater than that observed during preoperational testing when flow is used to test a swing or tilting disk valve.
3.1.44.1 Basis for Relief No instrumentation is provided for the determination of differential pressure across the valve.

j 3.1.44.2 Alternr.ce Testing A partial-st;-oke test will be accomplished during the quarterly testing of the MDAFW pumps.
Acceptance of the pump test will provide assurance that the 1
i valve has partially opened. A full-stroke test will be accomplished by pro-viding LDAFW pump design flow to the Steam Generators during cold shutdown.
l Verificaton that design flow is reached provides assurance that the valve has opened in order to perform its function.
