II.
Basis For Not Exercising Valves, In Accordance With IW-3412 (a):
The full stroke cycliry of these valves kulld stcp the flow of hot water (RCS letdown) through the coolers stule the coolirq medium continues to flow.
The cyclity of these valves will themally shock the heat exchangers by readmitting hot water to a cooled down acrponent.
The isolation of the cooling medium (SW systen) prior to the stroke of these valves wculd also themally shock the cxrponents, as cold water sculd be introduced into a hot environnent upon the return of SW flow.
These themal transients have proved in the past that the quarterly stroking of MN-40 and MN-41 is not conducive to the safe operation of the plant when, as a result of such testirn, the unit had to be renoved fren service for the replacenent of MJHE-1A and MJHE-1B.

'Ihe full stroke cyclim of these valves would stcp the flow of service water to aM frm the RG pirification letdown coolers. 'Ihe SW system provides the coolim rodium to these ccupenents. 'Ihe cyclim of these valves will thcIm11y shock the heat exchamers by read:nitting cold water to a heated ccryonent.
'Ihe isolation of RC water to each ocuponent prior to the stroke of these valves wculd also thermlly shock the ccuponents, as hot water would be introduced into a cold environment upon the return of RC flow (into the MJ system).
'Ihese themal transients have proved in the past that the quarterly streking of SW-47, 48, 49 ard 50 is not ccrducive to the safe cperation of the plant. As a result of such testing, the unit had to be rmoved frus servicx! for the replacement of MJHE-1A and MJHE-1B. kiiitionally, a large amount of expccure to personnel was incurred durim the replacmant activities.
III. Testing Currently Beim Perfomod:
'Ibece valves shall be fully strokad aM tired in the clcocd direction durim cold shutdcun.

I. Valves Identified Not 'Ib Be Exercisal During Norml Plant Operation:
a) Name ard identification number (cxxponent tag):
SW-79, SW-80, SW-81, SW-82, SW-83, SW-84, SW-85, SW-86, Reactor coolant punps 3A-2, 3A-1, 3B-2 and 3B-1 inlet isolations and reactor coolant punps 3A-2, 3A-1, 3B-2 and 3B-1 dischanje isolations.
b) Function:
'Ibese valves supply crsling water to the RC punps' I:ctor bearings, air cooler, ani seal area cooler during RC punp operation.
c) ASME Section III Code Class:
2.
d) Valve Category:
B.
II. Basis For Not Exercising Valves, In Accordanoo With IW-3412(a):
'Ihe failure of these valves during full stroke exercisirg would result in less of cooling water to the RC prps' rotor bearings, seals ard coolers.
'Ihis could damage the prps if an operator did ret take action to trip the prps.
III. Testing Currently Being Perfonxd:
'Ihese valves shall 1:e fully stroked and timed in the cloccd direction during cold shutdown.

I.
Valves Identified Not To be Exercised During Normal Plant Operation:
a) Name and identification number (component tag):
SWV-109 and SWV-110 3 Nuclear service water inlet and outlet isolations to Reactor Building.
b) Function: These valves furnish cooling water to the control rod drive mechanism (CRDM) stators.
c) ASME Section III Code Class:
2.
d) Valve Category:
B.
II.
Basis For Not 2xercising Valves, In Accordance With IWV-3412(a):
Exercising these valves would entail loss of cooling water for all CROM stators until exercising is complete.
The loss of cooling water to the CROM's could result in damage to the stators if the Operator did not take action to trip the reactor.
III.
Testing Currently Being Performed:
These valves shall be fully stroked and timed in the closed direction during cold shutdown.
