SUMMARY

OF HAY 2,

1994, CONFERENCE CALL TO DISCUSS THE IMPLEMENTATION OF GENERIC LETTER (GL) 89-10, "SAFETY-RELATED HOTOR-OPERATED VALVE (HOV) TESTING AND SURVEILLANCE," AT NINE MILE POINT NUCLEAR STATION UNIT NO.

1 (NHP-1)

By letter dated February 22, 1994, the NRC staff had expressed its concern regarding Niagara Mohawk Power Corporation (NHPC's) apparent lack of progress in resolving the HOV issues of GL 89-10 at NHP-l.

This apparent lack of progress had been noted in Combined Inspection Report No. 50-220/93-22 and 50-410/93-21 and in the NRC staff's review of NHPC's September 27,

1993, response to Supplement 5 of GL 89-10.

The February 22, 1994, letter also proposed holding a meeting to discuss NHPC's progress to date for implementing the provisions of GL 89-10 at NHP-l.

In response to the NRC staff's request for a me'eting, NHPC proposed to conduct a conference call rather than to hold a meeting.

The NRC staff agreed to the proposed conference call which was held on Hay 2, 1994.

In preparation for the conference call, NHPC provided a copy of its current schedule for completing GL 89-10 at NHP-1 to the NRC project manager for NHP-l.

Enclosure 1 is a copy of the information provided to the NRC project manager.

Enclosure 2 is a list of participants in the Hay 2,

1994, conference call.

During the May 2,

1994, conference call, NHPC representatives stated that 51 NHP-1 valves are within the scope of GL 89-10.

Approximately one-half of these 51 valves can be tested with the plant in operation, the remainder require the plant to be in a refueling outage during testing.

NHPC considers it practicable to dynamically test 28 of the 51 valves; the balance will be considered for grouping in accordance with the provision of Supplement 6 to GL 89-10.

NHPC also stated that of the 28 valves to be dynamically tested, 8 can be tested during plant operation while 20 require the plant to be in a refueling outage to perform dynamic testing.

NHPC stated that in accordance with its current plans and schedules, all of the GL 89-10 design-basis capability testing of NHP-1 valves will be completed by the end of the next refueling outage (currently scheduled to begin in February 1995).

The NRC staff considered the proposed schedule acceptable 9405i30i33 94050b'T PDR ADOCK-,05D00220 F D~R g jogga

STATUS OF IMPLEMENTATIONOF GENERIC LETTER 89-10 AT NINE MILE POINT UNIT 1

+

Diagnostic. equipment vendor manuals and maintenance procedures to support static testing have been issued.

Test equipment has been received on site.

Electricians and Engineering personnel have been trained in VOTES and Advanced VOTES.

+

An on-line, and outage schedule has been developed that accomplishes all

. testing by the end of the 1995 refuel outage.

(Schedules are attached)

As of the week of April 11, 1994 static testing has been completed on two valves.

Lessons learned from the first valve test are being incorporated into site and engineering procedures.

+

System Engineering, Operations and Design Engineering have started reviewing requirements, test methods and system configurations for development of test procedures for dynamically testable valves.

Final design reviews for 2 out of 51 valves is complete with final design reviews of the remaining 49 including operability reviews to be complete by the end of June 1994.

Pressure Locking/Thermo Binding review of gate valves is in progress with an expected completion of the end of May 1994.

Results of this review are being incorporated in the final design reviews.

N The PRA group has completed a review of valves in the Generic Letter 89-10 program and,has prioritized the list of valves based upon risk importance.

Engineering is reviewing plant valves and industry experiences to determine where grouping may be feasible.

This may result in fewer dynamic tests than currently scheduled.
