- McGUIRE NUCLEAR STATION PUMP INSERVICE TESTING PROGRAM ASME SECTION XI, SUBSECTION IEP The inservice testing of ASME Code Class 1, 2, and 3 pumps provided with an emergency power source will be tested as required by Section XI, Subsection IWP, of the ASME Boiler and Pressure Vcssel Code 1977 Edition and Addenda through summer 1978, except where specific written relief has been grcnted by the Commission. A description of the proposed inservice testing program, as well as specific requests for relief from code requirements determined to be impractical, is described by the following.

I. The following specific requests for relief from certain code requirements are to be appli:able for all pumps.

A) IWP-4120 requires the full scale range of each instrument to be three times the reference value or less. This was changed from four times the reference value in the edition of Section XI that was in effect prior to unit licensing. 10CFR, Section 50.55a(g)(4) states that design provisions are excluded from the requirement to upgrade to subsequent editions of Section XI. Since any cases where the three-times reference value criterion is not met would require design changes in instru-mentation, we will continue to apply the four-times reference value criterion, as interpreted in B) below, for instrument accuracy evaluation.

B) In several cases, instrumentation does not meet the four times reference value criterion. These cases predominantly involve suction pressure gauges where a larger range is required to accommodate varying conditions at the succion of the pump.

In all cases where the four-times reference value criterion cannotbemet,aninstrumenterrorevalu/ationisperformed to demonstrate that the overall accuracy of the differential pressure measurement is within the limits established by IWP.

C) Table IWP-3100-1 9atablishes the parameters that are to be measured. The r,revious edition of Section 11 specified that in a fixed zesistance system, either AP or Q was to be measured, not both. There are two systems that are tested using fixed resistance flow paths, with no flow indication provided. Based on the design change exclusion provided by 10CRF50.55a(g)(4), we will continue to apply the criterion that it is not required ta measure flow in a fixed resistance system.

D) IWP 4320 provides that the temperature of the pumped liquid be recorded. Since this value is not used in determining the acceptability of the pump, and has in fact been deleted from later revisions of the code, we do not plan to record this parameter.

REV. 2 8106160621

_3 II. The following Safety Class 1, 2, and 3 pumps (See Attachze*.c #1 for specific safety class and available instrumentation) will be tested in accordance with the intent of Subsection IWP of the ASME code:

NUCLEAR SERVICE WATER PUMPS (1A,1B)

CONTAINMENT SPRAY PUMPS (lA, IB)'

SAFETY INJE(; TION PUMPS (lA, IB)

MOTOR-DRIVEN AUX. FEEDWATER PUMPS (lA, IB)

TURBINE-DRIVEN AUX. FEEDWATER PLHP (NO.1)

CENTRIFUGAL CHARGING PUMPS (lA, IB)

COMPONENT COOLING PUMPS (lAl, lA2, 1B1, 1B2)

FUEL POOL COOLING PUMPS (lA, IB)

III. The following Safety Class 1, 2, and 3 pumps (See Attachment #1 for specific safety class and available instrumentation) will be tested in accordance with the intent of Subsection IWP, except for the request for relief for the specific requirements determined to be impractical as described below.

A) PUMP: BORIC ACID TRANSFER PUMPS (lA, 1B)

SAFETY CLASS: 3 FUNCTION: Boric Acid Tank recirculation, boric acid makeup and boric acid delivery to Centrifugal Charging pump suction TEST REQUIREMENT: 1. Measure pump bearing temperature during inservice testing.

i 2. Annually, run pump until bearing temperatures stabilize.

3. Observe proper lubricant level or pressure during inservice testing.

BASIS FOR RELIEF: There is no instrumentation installed to measure puip bearing temoerature. The subject pump / motor is of the completely enclosed " canned" type and therefore no meaningful temperature data can be obtained from pump surface temperature.

There is no lubricant level or pressure indication associated with the subject pumps as they are lubricated by the boric acid solution which they pump.

ALTERNATE TESTING: The inservice testing of the Boric Acid Transfer pumps will be in accordance with the intent of subsection IWP except for the following exceptions:

Bearing temperature will not be monitored and subsequently the pumps will not annually be run until temperature stabilization. The mechanical condition of the pumps will be determined from vibration data.

REV. 2

o .

I Lubricant level or pressure will not be j observed as they are not applicable to this pump design.

B) PUMP: CONTROL AREA CHILLED WATER PUMPS (CRA-P-1, CRA-P-2)

SAFETY CLASS: 3 FUNCTION: To provide chilled water to air handling .aits supplying control area air conditioning.

TEST REQUIREMENT: 1. Measure pump bearing temperature during inservice testing.

2. Annually run pumps until bearing temperatures stabilize.

BASIS FOR RELIEF: There is no instr.amentation installed to measure bearing temperature, and no meaningful data can be obtained from bearing housing surface tempera-ture measurements.

ALTERNATE TESTING: The inservice testing of the Control Area Chilled Water Pumps will be in accordance with the intent of Subsection IWP excapt that bearing temperature will not be monitored and subsequently the pumps will not be run annually until bearing temperatures stabilize. The mechanical condition of the subject pumps t:ill be determined from vibration data.

C) PUMP: BORON INJECTION RECIRCULATION PUMPS (1A,1B)

BASIS FOR RELIEF: Technical Specification 4.6.3.4 requires a lealc rate test on these valves whenever they are cycled. In addition, Technical Specification 4.6.1.9 places severe restrictions on the operational time and alignment permitted for this system during normal operation. Because of these re-strictions, it is not practical to cycle and time these valves quarterly.

ALTERNATE TESTING: Valves will be timed whenever the system is operated or whenever the valves are cycled, and the elapsed time

since the previous test has been 3 months or greater.
