This letter transmits a revision to the In-service Testing Program for the Donald C.

Cook Nuclear Plant.

This revision results from our response to Inspection Report 50-315/90201 and 50-316/90201 Open Item 90-201-09, "Lack of Inclusion of Certain ESW Check Valves Into IST Program."

(Reference 1)

The program has revised the requirements for the following essential service water system valves:

1-ESW-111 1-ESW-112 1-ESW-113 1-ESW-114 1-ESW-101E 1-ESW-101W 2-ESW-141 2-ESW-142 2-ESW-143 2-ESW-144 2-ESW-102E 2-ESW-102W 9i04i70ii0 9i0409 PDR ADOCK 05000315 9

Dr. T. E. Murley AEP: NRC: 0969S The revised pages of the IST program are included in Attachment l.

These changes will be implemented by July 10, 1991.

This will allow time to revise the applicable test procedures.

As part of our response to the open item, we committed to review the IST program for those check valves not currently assigned a

backflow checking safety function, and to make any changes deemed necessary.

This review, which is currently in progress, has been expanded beyond the scope identified in our February 16, 1990 (Reference

2) submittal, and it is estimated that the review will be completed with necessary program changes submitted by October 30, 1991.

Additionally, during the review for this submittal, we discovered two changes to our IST program which were not specifically identified in Attachment 4, Item 3 of our February 16, 1990 submittal.

These changes are the deletion of the full flow test for valves RH-133 and -134 (these are passive valves which have no open safety function) and a revised relief request for valves SI-158, Ll thru L4 and SI-161, Ll thru L4.

The relief was requested because of radiation exposure to plant personnel taking the required flow measurements rather than low temperature overpressure concerns noted in the Safety Evaluation Report (Reference 3).

The previously submitted pages of the IST program are included as Attachment 2 for your information, This letter has been reviewed by the Plant Nuclear Safety Review Committee, This document has been prepared following Corporate procedures that incorporate a reasonable set of controls to ensure its accuracy and completeness prior to signature by the undersigned.

Sincerely,p~

ESW-111

-112

-113

-114 Code Relief These check valves open to provide cooling water flow to various Emergency Diesel Generator loads.

In addition, these valves close to prevent back flow into the opposite ESW train header.

The open safety function will be tested in accordance with IWV-3520.

The closed safety function cannot be tested in accordance with IWV-3520 for the following reasons:

There are no external position indicators associated with the valves, and no instrumentation or taps available at the valve to determine positive closure.

In order to determine valve

closure, an entire ESW header and safety train, including both Emergency Diesel Generators, must be removed from service.

These valves cannot be tested at cold shutdown frecpxency since, with fuel

loaded, the ESW is at its highest load demand (RHR operating) at this time and cannot be removed from service.

The closed safety function of these valves shall be verified by disassembly at refueling frequency.

NOTE 2:

ESW-109

-115

-243 Cold Shutdown Justification These valves are normally closed and are required to be open when the condensate storage tank is exhausted.

Exercising the valves could cause lake water contamination of the steam generators.

Lake water chemistry can potentially impact steam generator tube integrity.

Therefore, the valves will be full stroke tested at a cold shutdown frequency.

Since the valves are manual, stroke timing is not required.

WRV-721

-723

-725

-727 Code Relief These valves are located in the essential service water supply lines to the emergency diesel generators air after coolers.

These three-way valves regulate water flow to maintain the temperature at which the after cooler air discharge thermostatic controller has been set.

Water flow is regulated by passing a portion of the flow through the air coolers and bypassing the excess flow around the air after coolers.

Code relief is being requested from the testing requirements since (1),

these valves function only as regulating valves and not open/closed valves (2), these valves are demonstrated operable during diesel generator testing (diesel generators are tested per Technical Specification 4.8.1.1.2);

and (3), these valves are demonstrated operable during diesel generator 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> runs performed each refueling outage.

The valves will be "fail-safe" tested using their control scheme that will remove air from the valve operators causing them to direct all ESW flow to the air after coolers.

This proposed test for each valve will be performed at refueling frequency.

The valves cannot be stroke timed because they are thermostatic valves whose position is controlled by process fluid temperature.

There is no external control available.

NOTE 4:

ESW-101E

-101W Comment Testing of the backflow checking function cannot be performed if the opposite unit's ESW System is not available.

Should the opposite unit's ESW System not be available when testing of this valve's backflow checking function is required, the testing will be deferred until-the opposite unit's ESW System is returned to service, and will be performed as soon as practical thereafter.

SI-166-1 throu h 4

Code Relief These check valves function to prevent backflow from the RCS into the accumulators during normal operation.

These valves function to supply flow from the accumulators to the RCS during an accident condition.

These valves cannot be exercised during power operation because the accumulators do not have sufficient head to overcome RCS pressure.

These valve's cannot be exercised during cold shutdown because this would result in a possible low temperature overpressurization of the RCS; Full stroke testing during refueling outages is not possible because of the resulting water surge into the reactor and the potential for high airborne radiation contamination.

These valves will be part stroke exercised at refueling frequency.

The valves will be disassembled, manually full stroke exercised and visually examined on a sampling basis (one of four) per GL-89-04, Attachment 1, Item g2, at re'fueling frequency.

NOTE 6:

SI-161 Ll L2 L3 L4 Code Relief These check valves are located in the supply lines from the Residual Heat Removal and Safety Injection Pumps to.the RCS cold legs (loop 1 through 4).

These valves cannot be exercised during power operation because the RHR pumps and SI pumps do not develop sufficient head to overcome RCS pressure.

Full stroke of these valves (individually) cannot be verified at cold shutdown frequency because flow instrumentation is not available downstream of the flow split.

These valves will be part stroke exercised at cold shutdown frequency and full stroke will be locally verified using portable instrumentation at refueling frequency.

S Code Relief These check valves function to provide Safety-Injection pump discharge to either the hot or cold legs.

These valves cannot be exercised during power. operation because the SI pumps do not develop sufficient pressure to overcome RCS pressure.

These valves cannot be exercised during cold shutdown because the safety injection pumps are required to be inoperable by Technical Specification Section 3.5.3, to protect against low temperature overpressurization of the reactor vessel.

Also, during cold shutdown, there may not be sufficient volume in the RCS to accommodate the amount of water needed to full stroke.

These valves will be full stroke exercised at refueling frequency.

SI-158 Ll L2 L3 L4 Code Relief Check valves SI-158 are located in the supply lines from the Residual Heat Removal and Safety Injection Pumps to the RCS hot legs (loop 1 through 4).

These valves cannot be exercised during power operation because the RHR and SI pumps do not develop sufficient head to overcome RCS pressure.

Full stroke of these valves (individually) cannot be verified at cold shutdown frequency because flow instrumentation is not available downstream of the flow split.

These valves will be part stroke exercised at cold shutdown frequency.

Full stroke will be verified using portable instrumentation at refueling frequency.
