DEC 0 21987 MEMORANDUM FOR: R. D. Lanksbury, Team Leader, Perry Augmented Inspection Team (AIT)

FROM: Hubert J. Miller, Director, Division of Reactor Safety

SUBJECT:

AIT CHARTER Enclosed for your implementation is the Charter developed for the inspection of the events associated with the Perry MSIV failure which occured on November 29, 1987. This Charter was prepared in accordance with the NRC Incident Investigation Manual and the draft AIT implementing procedure issued for use on October 2,1987, and is based on the discussions you had with Region III personnel on November 30, 1987. As stated, the objectives of the AIT are to communicate the facts surrounding this event to regional and headquarters management, to identify and communicate any generic safety concerns related to this event to regional and headquarters management, and to document the findings and conclusions of the onsite inspection.

If you have any questions regarding these objectives or the enclosed Charter, please do not hesitate to contact either myself or Monte Phillips of my staff.

DEC a1937 Dodet No. 50-440 Docket No. 50-441 The Cleveland Electric Illuminating .

Company ATTN: Mr. Murray R. Edelman Vice President Nuclear Group l Post Office Box 5000 l Cleveland, OH 44101 Gentlemen:

SUBJECT:

CONFIRMATORY ACTION LETTER NO. CAL-RIII-87-24 On November 29, 1987, a Main Steam Isolation Valve (MSIV) failed to close. This is the same type of event which occurred on October 29 and November 3, 1987, for which Confirmatory Action Letter No. CAL-RIII-87-19 was issued. As a result of the most recent event, an Augmented Inspection Team (AIT) was dispatched to the l site and a Confirmatory Action Letter (CAL-RIII-87-24) was issued on November 30, ,

1987, to document our understanding that you would perform the following actions pursuant to the review of the MSIV failure: '

i l 1. Take those actions necessary to ensure that complete documentary evidence of the "as found" condition of equipment being inspected is maintained.

2. Provide a step by step troubleshooting program to establish the root cause of the MSIV failure.

l l 3. Not disturb any components that offer a potential for being the root l cause including power sources, switches, solenoids, and the air system

! directly feeding the MSIVs until that action is approved by the leader of l the NRC AIT which has responsibility for examining this matter. We l

recognize that, per our authorization of November 29, 1987, the air pack was removed from MSIY IB21-F022B and the associated ASCO dual solenoid 3-way pilot valve was disassembled with the NRC AIT Team Leader present.

4. Except as dictated by plant safety, advise the NRC AIT Team Leader prior to conducting any troubleshooting activities. Such notification should be provided soon enough to allow time for the Team Leader to assign an I

inspector to observe activities.

5. Submit to NRC Region III a fomal report of your findings and conclusions I within 30 days of receipt of the November 30, 1987, Confirmatory Action I Letter. You may extend the submittal date of the fomal report requesteo in the NRC Confimatory Action Letter dated November 4,1987, to within l 30 days of the receipt of the November 30, 1987, Confimatory Action l Letter. I l

Q

DEC e 3987 The Cleveland Electric Illuminating 2 Company  ;

The November 30, 1987, Confinnatory Action Letter also specified that the -

plant would not be restarted without the concurrence of the Regional Administrator or his designee.

With respect to Items 1 through 4, you have completed all of the specified actions and these have been evaluated by the AIT. Their report will be issued shortly. With regard to Item 5, we understand you will submit to Region III a formal report as specified.

Based on a review of your corrective actions and commitments as specified in '

your letters dated December 4,1987 (PY-CEI/01E-0296L), and November 13, 1987 (PY-CEI/0!E-0289L), and based on the results of our AIT inspection, we believe you have established adequate plans for continued safe operation of the plant and for final resolution of this matter. Based on these reviews and conclusions, NRC concurrence was given in a telephone conversation between H. Miller and A. Kaplan on December 4, 1987 to restart the Perry Plant. This letter confirms that conversation.

Sincerely, I he w A. Bert Davis Regional Administrator See Attached Distribution n
