DUKE po T.R COMPANT HCGUIRE WUCI. EAR STATION FUMp INSERVICE TESTING PROGRAM AsME SECTION KI, SUBSECTION IW
- The inservice testing of ASME Code Class 1, 2, and 3 pumps provided with as energency power source will be testad as required by Section XI, subsection IW, of the ASME. Boiler and prsssure Vessel Code 1930 Edities, except where specific written relief has been granted by the Commission. A descripties of the proposed inservice testing program, as well as specific requests for relief free code requirements determined to be impractical, is described by' the following.
NOTE: The initials and date of the person or persons responsible for l 10 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 i meet the intent of IWP-6240 (f).
4 1. The following are specific requesta for relief from certata code l requirements. (
A) IW-4120 requires the full seale range of each instrument to be three times the reference value er less. This was changed from four times the reference value in the edities of Secties 11 that was in effect prior to unit licensias. 10CFR, Secties 50.5Sa(s)(4) states that design previsions are escluded from the requiremmat te upgrade to subsequest edittens of Secties II. Since any casee ishere the three-times reference value criteries is met met would require design changes is instrumentation, we will contians to apply the four-times reference value criteries, as interpreted is 3) below, O for instrument accuracy evaluaties.
- 8) In several cases, instrumentaties does set meet the four times reference value criterios. These cases predestaastly Lavelve sucties pressure gauges where a larger range is required to acceerndate varying conditione at the sucties of the pump. In all cases where the four-times reference value criteries casset be met, an instrument errer evaluaties is performed to demonstrate that the overall accuracy of the differential pressure messaremsat is withis the limits established by IW, These cases are RER discharge, nuclear service water sucties, and control reen chilled water suction sages.
c) Tsble IVp-3100-1 establishes the parameters that are to be
- measured. The previous edition of Section 11 specified that in a fixed resistance system, either AP er Q was to be measured, not 4l both. The centrifugal charging pumps are tested using fixed resistance i l
flow paths, with no flow indication provided. The Safety Injection Pumps are in a fixed resistance system that does 8 have a flow gauge available. but unnecessary radiation exponure and manpower is required to measure the flow. Based on the design change esclusies provided by 1MTR50.55a(s)(4), we will contiane to l r 5l apply the criteries that it is set required to measure flow is a fixed resistance system. The Residual Heat Removal pumps are in a fixed resistance system that does have a flow gauge available. There y\ is no way to adjust flow in the system and the gauge is not suffi-l 5 ciently accurate at low flows to provide a precise indication of I flow. For these pumps, a flow will be recorded but vill not be !
' used f or comparison to any ref erence values. l McGUIRE-UNIT 1 ion 10
O D) Table TVP-4110-1 states tr.at vibration measurement should have an accuracy of i St. McGuire has no permanently installed vibration tas trumentation. The portable instrvosats used to seasure vibration have as uncertainty of g 112.
E) IWP-3100. Table IWP-3100-1 and IWP-3300 reqaires 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 failuro by temperature measurement does not justify the additional pump operating time required to obtain the measurement. Consequently, McGuire does not require annual bearing temperature measurements per the ASME Section XI code.

DEFINITIONS OF TESTING REQUIREMENTS AND Al ERNATIVES Cold Shutdown (CS) Testing vill be performed when the unit is in a i cold shutdown (Mode 5) whose planned length is 4 of sufficient duration to establish necessary , ,
test conditions and to perform the test.' In the f case of frequent shutdowns, the testiuy will not .
10 [ be performed more than once per three (3) months. l l Testing will commence as soon as the cold shut- '
4 down condition is achieved but not later than !
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 complete or the plant is ready to return to powe r. Completion of all valve testing is not a prerequisite to return to power. Any testing not completed at one cold shutdown will be per-formed during any subsequent cold shutdowns that may occur before refueling to meet the code- ,
specified testing frequency. Any valve speci-fied to be tested during/at (CS) may be tested during Refueling Outage (RF) conditions.
10 Cold Shutdown (CS*) Same as (CS) except testing may be performed prior to and/or after Cold Shutdown (Mode 5) +
as specified in alternate testing.
Cycle and Time (CT) Valve will be tested to verify that its stroke time is less than the maximum allowable stroke time specified by McGuire Nuclear Station.
- Leak Test (LT) Valve will be tested to verify that the seat leakage is limited to a specific maximum aucunt.
6 Movement Test (MT) Valve will be tested to verify that the valve is operable and/or the valve noves to the position
- required to fulfill its purpose. No timing is ;
- involved. ,
j Quarterly (Q) Testing will be performed at least once per l three (3) months. ;
Refueling Outage (RF) Testing will be performed when the unit is shut down for refueling (Mode 6). Safety valves will be tested periodically per the testing
] schedule defined in ASME Subsection IW-3510.
t Testing may be done while in No Mode as well 10 j as Mode 6. ;
Refueling Outage (RT*) Valve will normally be tested during refueling outages, however, testing is not required more i often than once per 24 months per Appendix J to i 10CTR50.
McGUIRE-UNIT 1 11.3-1 Revision 10 l
l 1
Refueling Outage (RFf) Valve will normally be tested on a rotating basis via a sample valve diassembly program (1 valve f
from a group of identical valves 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.
1 Setpoint (SP) Valve vill be tested to verify that it will relieve pressure at its specified setpoint.

TEST REQUIREMENT: Cycle and time valve once per three months.
BASIS FOR RELIEF: Cycling valve during power operation could induce unwanted transients in steam generators. This would 4
result in an increase in flow to the main feedwater nozzles causing vibrations in the preheater section i of the steam generators. 1 ALTERNATE TESTING: Valve will be cycled and timed during cold shutdowns. '

MC-1591-1.1 VALVE: 1CF-152, ICF-154, ICF-156, ICF-158 CATEGORY: C CLASS: B TbNCTION: Provides tempering flow to the steam generator auxiliary feedwater nozzles.
TEST RE7UIREMENT: Exercise valve to prove valve closes to prevent reversal of flow quarterly.
BASIS FOR RfLIEF: During normal operation, there is constant flow through these check v'alves to keep the auxiliary feedwater nozzles tempered. Testing these check valves would require supply-ing the steam generators with cold auxiliary feedwater and thus thermally shocking the nozzles.
ALTERNATE TESTING: Luring cold shutdown, each valve will be e.xercised te each valve closes to prevent gross diversion of flow.

VALVE: 1WL-466 r CATEGORY: C t CLASS: F i
FUNCTION: Prevents steam flow from lower containment to upper containment bypassing the ice condenser in an accident. l TEST REQUIREMENT: Full stroke exercise quarterly.
BASIS FOR RELIEF: The check valve is on a drain line from the VX Fan Pit to lower containment. The valve is located at the end -
of a six inch pipe in lower containment and cannot be i accessed without radiation exposure and safety related risks. The check valve is normally closed and has no j fluid on the valve. :
ALTERNATE TESTING: The valve will be visually inspected during refueling outages to ensure free movement. (No disassembly will -
be required).

CATEGORY: B CLASS: B FUNCTION: Isolate the containment sump (lNI-184 isolates train B, 1NI-185 isolates train A). These valves also provide sn alternate source for suction to the Residual Heat Remival Pumps.
SASIS Fd RELIEF: Due to interlocks in the Safety Injection System and the actual Residual Heat Removal design, it is impossible to test tSese valves without rendering both trains of Residual Heat Removal and both trains of Safety Injection 4 inoperable. During cold shutdowns, the RHR pumps are required for decay heat removal.

BASIS FOR RELIET: The valve is normally aligned for safety injection with !
power removed, as required by McGuire Technical Specification !
4.5.2. Cycling the valve with the plant in operation requires that the power be restored to the valve and moved from the. f event-initiation position. The valve is required for align- i ment for hot-les recirculation following an accident. It is not
! required to automatically actuate on initiation of a safety event.t The past test history of the valve is very good.
