O The inservice testing of ASME Code Claes 1, 2, asd 3 pumps provided with an emergesey power seurce will be teeted as required by Section XI, Subsection IVP, of the ASE leiler and Pressure Vessel Code 1930 Edities, except where specific writtes relief has been granted by the Ceemissies. A description of the proposed inservice testing program, as well as specific requesta for relief free code requirements determined to be impractical, is described by the,fellowing.
I NOTE: The initials and date of the person or persons responsible 6
for conducting and analyzing the test may be used in place of a signature in the record of tests. Initials shall be construed as signatures to meet the intent of IWP-6240 (f) . {
!. The following are specific requests for relief from certata code requirements.
A) IVF-4120 requires the full scale range of uch instrument to be three times the reference value er less. This was changed from isur times the reference value in the edities of Secties 11 that was in effect prior to unit licensias. 10CFR, secties 50.35e(s)(4) states that design previsions are escluded from the requirement te upgrade to subsequent editions of Secties II. Since say cases where the three-times refereace value criteries is set met would require design changes in instrumentaties, we will continue to apply the O four-times reference value criteries, as interpreted is 3) bel,ew, for instrument accuracy evaluaties.
- 3) In seve
- a1 cases, instavesentation dess set meet the four times reference value criteries. These casas predestaastiv intelve aucties pressure gauges where a larger range is requated to acceGedats varying conditions at the suction of the pump. In all cases where the four-times reference value criterios caanet be met, as instrum st errer evaluaties is performed to deseastrate that the everall accuracy of the differential pressure esasurement is withia
- the limits established by IVP. These cases are RER discharge, I auelear service water sucties, and control reos chilled water sucties gages.
l C) Table IVP-3100-1 establishes the parameters that are to be measured. The previous edities of Secties 11 specified that in a fixed resistance system, either AF or Q was to be assaured, act both. The centrifugal charging pumps are tested using fixed resistance j flow paths. with no flow indication provided. The Safety
, Injection Pumps are in a fixed resistance system that does
! ' have a flow gauge available, but unnecessary radiation exposure i and manpower is required to measure the flow. Based on the design change esclusies provided by 10CTR50.55a(s)(4), we vill continue to i
tl apply the criteries that it is not required to measure flew in a l
1 fixed resistance system. The Residual Seat Removal Pumps are in a fixed resistance system that does have a flow gauge available. There
]
i O 1 is no way to adjust flow in the system and the gauge is not auffi-ciently accurate at low flows to provide a precise indication of i flow. For these pumps, a flow will be recorded but will not be used for comparison to any reference values.
McGUTRE - UNIT 2 !.1-1
{ Revision 6 J
D) Table IVF-4110-1 states that vibration esasurement should have an accuracy of g 5%. McCuire has no permanently installed vibration instrumentation. The pertable instruments used to measure vibration have sa uncertainty of i 11%.
E) IVP-3100. Table IkT-3100-1 and IkT-3300 requires the measurement of bearing temperature annually. It has been demonstrated by experience that a bearing temperature rise occurs only minutes prior to bearing failure. Therefore, the detection of possible bearing failure by a yearly temperature measurement is unlikely.
Obtaining these measurements requires a. minimum of one-half hour of pump operation to achieve stable bearing temperatures. The small probability of detecting bearing failure by temperature measurement does not justify the additional pump operating time required to obtain the measurement. Consequently, McGuire does not require cnnual bearing temperature measurements per the ASME Section XI code. ,

McGUIRE - UNIT 2 11,2-1
DEFINITIONS OF TESTINC. REQUIREMENTS AND ALTERNATIVES i
Cold Shutdown (CS) Testing vill be performed when the unit is in a i
cold shutdown (Mode 5) whose planned length is :
of sufficient duration to establish necessary i i
test conditions and to perfore the test. In the ,
1 case of frequent shutdowns, the testing will not #
I be performed more than once per three .(3) months. l l 6
l Testing vill commence as soon as the cold shut-4 down condition is achieved but not later than !
i 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> after shutdown, and continue until e complete or the plant is ready to return to ;
power. Completion of all valve testing is not I a prerequisite to return to power. Any testing not completed at one cold shutdown will be per- 1 l formed during any subsequent cold shutdowns that I i may occur before refueling to meet the code-
- specified testing frequency. Any valve specified to be tested during/at (CS) may be tested during i j Refueling Outage (RF) conditions.
5 6 Cold Shutdown (CS*) Same as (CS) except testing may be performed !
I prior to and/or after cold shutdown (Mode 5) as specified in alternate testing.
t i f Cycle and Time (CT) Valve will be tested to verify that its stroke
! time is less than the maximum allowable stroke -
1 time specified by McGuire Nuclear Station. l Leak Test (LT) Valve vill be tested to verify that the seat !
leakage is limited to a specific naximum amount. j
- i
- Movement Test (MI) Valve will be tested to verify that the valve is ,
j operable and/or the valve moves to the position )
required to fulfill its purpose. No timing is !
1 involved.
Quarterly (Q) Testing will be performed at least once per i three (3) months.
}
l Refueling Outage (RF) Testing will be performed when the unit is i shut down for refueling (Mode 6). Safety valves j will be tested periodically per the testing schedule defined in ASME Subsection IWV-3510.
I 6 Testing may'be done while in No Mode as well as Mode 6.
) Refueling Outage (RF*) Valve will normally be tested during refueling
' outages, however, testing is not required more
' of ten than once per 24 months per Appendix J to
' 10CTR50. j 1
McG1]IRI - UNIT 2 11.3-1 Revision 6
_ . - ~ .__ _ . _ . . _ .
O Refueling Outage (RFf) Valve will normally be tested on a routine basis via a samplw valve disassembly program (1 valve from a group of identical "tives under similar system conditions). Failure of one valve of the group during a refueling outage vill result in all remaining valves of the group being tested during that outage.
Setpoint (SP) Valve vill be tested to verify that it Will relieve pressure at its specified setpoint.

11.3-2 NCUIRE-UNIT 2 Revision 6 New Page
,f CINERAL RELIIT 1 l 1. TEST REQUIRDENT:
Perform trend analyses on category A and 3 valves
. as described in IW-3417(a) .
BASIS FOR RELIIFs Trend analyses performed on rapid acting valves'does not give reliable indication of valve stroka time deterioration.
TESTING ALTERNATIVE: Trend analyses vill not be performed on valves that normally operate with cycle times of less th.an 5 seconds. Maintenance will be initiated if valve time exceeds max. limit.
6 (CENERAL RELIEF II DELETED)
O .
III. TEST REQUI1 DENT: Laak rate test Category A valves in accordance with '
IW-3420.
BASIS TOR RILIIFt McGuire Tech Specs require leak rate testing in accordance with 10CTR50 Appendix J. The Tech Specs establish the required acceptance criteria, which is 1 more restrictive than that required by IW. In order to eliminate redundant paperwork, all valve leak rate testing vill be conducted as per Appendix J.
TESTING ALTIRNATIVI: Category A valves will be leak tested in accordance with 10C7150 Appendix J.

BASIS FOR RELIEF: Full stroke exercising of these check valves is not practical since there is no external indication of disk movement. Full stroke exercising would require for the pumps and spray nozzles to be activated which would 3 ft9uire a 18r88 8C818 Clean up effort. Provisions for disassembly of these 8 inch valves are not installed, thus subjecting personnel to an extreme hazard due to the valves location up near the containment dome.
ALTERNATE TESTING: These valves vill be tested during rifueling outages by partial stroke exercising the valves using air.

TEST REQUIREMENT: Exercise valve to prove valve closes to prevent reversal of flow quarterly.
BASIS FOR RELIEF: During normal operation there is constant flow through these check valves to keep the auxiliary feedwater nozzles tempered. Testing these check valves would require supplying the steam generators with cold auxiliary feedwater and thus thermally shocking the nozzles. ,
ALTERNATE TESTING: During cold shutdown, each valve vill be exercised to prove each valve closes to prevent gross diversion of flow.

P MC-2593-1.2 VALVE: 2SA-5, 2SA-6 ,
i CATECORY: C ,
i CLASS: B ;
i i TUNCTION: 1) Passes steam to supply the turbine driven ,
auxiliary feedwater pump. !
- 2) Prevents cross connecting steam generators 28 and 2C.
l TEST REQUIREMENT: 1) Full stroke exercise quarterly.
- 2) Verify valve prevents reversal of flow quarterly. [
t BASIS FOR RELIEF: 1) None required.
- 2) System configuration and design do not provide a suitable means to prove the valve prevents reversal ,
of flow. To check this valve on line would risk
- personnel safety since high energy steam would be :
involved.
t ALTERNATE TESTING 1) None required. '
i
- 2) At least one of the two valves will be disassembled '
j and inspected (verified to close) during each !
j refueling. Both valves vill have been disassembled and inspected after.two consecutive refueling outages.
] Failure of one valve to function properly during a 1 refueling outage will result in the remaining valve j being disassembled and inspected during that outage. :

BASIS FOR RELIEF: One of the ECCS safety analysis assumptions is that each train of ND can supply flow to all four cold legs.
If either of these valves fails closed during testing, then only two cold legs could be supplied by each train of ND. This would make both trains of ND inoperable.
ALTERNATE TESTING: Cycle and time at cold shutdown. ~!

i MC-2562-3.1 VALVE: 2NI-165, 2NI-167, 2NI-169, 2NI-171 CATEGORY: A, C CLASS: A i l
~
FUNCTION: SI discharge check valves. l l
TEST REQUIREMENT: Full stroke exercise quarterly. '
i BASIS FOR RELIEF: Valves cannot be cycled during power operation since the SI pu=ps cannot overcone RCS pressure to pemit i flow through the valves. During cold shutdowns I exercising these valves could result in low tempera-ture overpressurization.
6 ALTERNATE TESTING: Full stroke exercise at refueling. Valves will be leak !
tested in accordance with Technical Specifications.

MC-2562-3.1 VALVE: 2NI-180, 2NI-181, 2NI-175, 2NI-176 CATEGORY: A, C CLASS: A FUNCTION: Openr, on flow from the ND or NI to NC System. ,
TEST REQUIRE.ENT: 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 sufficient for opening the valve to the Reactor Coolant 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.
6 Valves will be leak tested in accordance with Technical Specifications.

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, i 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. 1 l

CATEGORv: B !
i CLASS: B l
FUNCTION: Isolates ND flow to the hot legs. '
t TEST RIQUIRIMENT: Cycle and time valve quarterly. !
BASIS FOR RELIEF: The valve is normally aligned for safety injection with i power removed, as required by McGuire Technical Specificatic: !
4.5.2. Cycling the valve with the plant in operation requires that the power be restored to the valve and moved from the event-initiation position. The valve is required for align- i O ment for hot-leg recirculation following an accident. It is requiredtoautematicallyactuateoninitiationofasafetyeven{

The past test history of the valve is very goed.
ALTERNATE TESTING: Cycle and time the valve at cold shutdown.
