2. Areas Discussed

Mr. Forney stated that the purpose of the reeting was for the licensee to

discuss the corrective actions implerented for the violation identified

in Inspection Report 265/88015(DRf).

Mr. Morrcngiello presented a brief description of the issue which was

docurented in Inspection Report 88015. Attachment 1 is a copy of the

overhcads which were used to take the presentation.

The licensee presented a detailed description of the event, imediate

corrective actions, and Ceco's view of the event's safety significance.

The handouts used for this presentation are included as Attachtrent 2 to

this report. The licensee stated that it was their intention to review

other situations where other devices have two power supplies and an auto

transfer feature, and equiprent with more than one electrical path for

start, stop or control functions, to determine if adcquate testing has

been done. Surveillances will be added or codified where a need to do so

is identified.

.

The abeve plan was to be accomplished in three phases. The first phase

consisted of reviewing all safety related schenatic drawings with similar

potential wiring errors, determine which were tested, and for those not

tested include them in the surveillance program. The second phase would

assure that all safety related equipment is being tested adequately under

the present surveillance program. The third phase will be to transfer

Quad Cities lessons learned to Dresden.

The rxeting was concluded with NRC stating that the program described

during the meeting by the licensee appeared to adequately address the

identified concerns. The hRC requested that the lessons learned be

applied to all Corrronwealth Edisen plants and that the resident

inspectors be kept appraised of the program's progress and results.

EVENT DESCRIPTION

FOUND UNLANDED LEAD IN RHR SWING MOTOR CONTROL CENTER (MCC)

DURING A MODIFICATION TEST.

- DISCOVERED 06/22/88 AT 5:00 PM.

- IMMEDIATE INVESTIGATION STARTED.

- REPORTED VIA RED PHONE CALL AT 7:50 PM.

- REPAIRED AND COMPLETED MOD TEST PRIOR TO 9:00 PM.

- ESTABLISHED TASK FORCE.

.

POWER To LPCI INJECTION VALVES FOR BOTH DIVISIONS AFFECTED.

,

DISCOVERED BECAUSE NEW MODIFICATION PROGRAM REQUIRES

DETAILED TESTING AND ACCEPTANCE CRITERIA. '

- WALKDOWN WAS PERFORMED IN PLANNED WORK LOCATION.

MOD ACCEPTANCE TEST INCLUDED VERIFICATION OF AUTOMATIC

r

TRANSFER OF tie RHR SWING MCC.

RHR SWING MCC FAILED TO TRANSFER DURING INITIAL MOD TEST.

STATION PERSONNEL INVESTIGATED, FOUND UNLANDED WIRE.

l

ENGINEERINC REVIEW SHOWED THAT THE MISSING WIRE WOULD

l INHIBIT AUTOMATIC TRANSFER. MANUAL ACTION BY THE OPERATOR

WOULD STILL BE EFFECTIVE.

BASES FOR "ACTION PLAN"

TASK FORCE ESTABLISHED WITHIN ONE WEEK OF DISCOVERY OF

CONDITION.

EVALUATED REASON WIRING ERROR NOT DETECTED.

CONCLUDED THAT ACTION PLAN SHOULD FOCUS ON THREE AREAS:

- DEVICES WITH TWO POWER SUPPLIES AND AUTO TRANSFERS.

- EQUIPMENT WITH MORE THAN ONE ELECTRICAL PATH FOR START,

,

STOP OR CONTROL FUNCTIONS.

- QUAD CITIES LESSONS LEARNED TRANSFERRED To DRESDEN.

THESE WERE CHOSEN BECAUSE:

- AUTO TRANSFER DEVICES

-- ROUTINE AYAILABILITY TO NORMAL POWER MASKS INABILITY

TO AUT0-TRANSFER.

-- NOT OFTEN CALLED UPON TO OPERATE.

- PARALLEL START /STOP/ CONTROL FEATURES

-- ROUTINE SURVEILLANCES VERIFY ONE PATH, BUT DO NOT

ADDRESS OTHERS, COULD MASK A WIRING PROBLEM.

- QUAD CITIES LESSONS LEARNED TRANSFERRED TO DRESDEN.

-- DRESDEN SAME VINTAGE AS QUAD CITIES STATION.

EVALUATION OF SAFETY SIGNIFICANCE

WIRING ERROR COULD PREVENT AUTOMATIC RHR INJECTION UNDER

GIVEN SIMULTANEOUS LOCA, LOOP, LOSS OF UNIT 2 DIESEL.

SITE SPECIFIC AND GENER4LLY APPLICABLE CALCULATIONS SHOW

PROBABILITY OF THESE SlHULTANEOUS OCCURRENCES LESS THAN

3 X 10-7 EVENTS PER YEAR.

SINGLE CORE SPRAY PUMP OPERATION ORIGINAL LICENSE BASIS FOR

PLANT. HOWEVER, TODAY'S APPENDIX X ANALYSIS DOES NOT

ADDRESS THIS CONFIGURATION.

EMERGENCY OPERATING PROCEDURES WOULD DIRECT OPERATOR TOWARD

RESTORING POWER TO THE RHR SWING MCC.

THEREFORE, ALTHOUGH EVENT CONSEQUENCES POTENTIALLY

SIGNIFICANT, PROBABILITY OF OCCURRENCE EXTREMELY LOW, AND

OPERATOR WOULD LIKELY RESPOND PROPERLY.
