SUMMARY

OF MEETING HELD ON SEPTEMBER 24, 1987, BETWEEN NRC 1 STAFF AND APCo REPRESENTATIVES TO DISCUSS RECENT PROBLEMS j RELATED TO QUALIFICATION OF V-TYPE ELECTRICAL SPLICES AT j FARLEY FITE.

]

Introduction ]

TheNRCProjectManager(E. Reeves)reviewedtheourposeofthemeetingand i asked all personnel in attendance to state their name and affiliation. A list l of attendees is enclosed.

}

NRC (S. Varga) noted that the NRC staff has serious concerns about the quali- .l tication of V-type electrical cable splices at Farley site. Region II  !

Administrator (N. Grace) reviewed briefly the recent history of V-splice l problems and actions taken by Alabama Power Company (APCo, the licensee) at l Farley site. He reiterated the NRC staff concerns. '

APCo (P. Mcdonald) spoke to the challenge being offered to discuss this matter.

He stated he would speak to the safety of the plant in which he maintains a l strong confidence of the continued safety. APCo (J. Woodard) discussed the j ,

basis of actions taken to date, the actions already taken, actions now underway, and actions planned. The history of the EQ V-splice Program at Farley site was reviewed. In June 1987, APCo set up a review program of 6000 work request packages completed at Farley.- This action resulted from the-Yendor/ Procurement team audit conducted by NRC for three-weeks concluding on '

June 5, 1987. APCo is reviewing each category of equipment considered of safety significance. They subsequently inspected and repaired those .V-splices found not to be in accordante with design. APCo stated that the V-splices which were found were not considered as inoperable. They-had replaced the i splices with RAYCHEM type splices known' to be qual _ified in a steam environment. Other splices were destroyed during the inspection process and  ;

RAYCHEM type splices were used as replacements; He noted that the Unit 2 l refueling shutdown is scheduled to start on October 3, 1987. ' Unit I refueling l shutdown is scheduled March 17, 1988. APCo plans walkdown inspections, including inside containment, to be performed and corrective actions'taken, where necessary. In sunmary, Mr. Woodard stated that APCo never declared a splice to.be inoperable, always acted with safety as the overriding criterion, and alwayG acted rapidly and conservatively.

APCo (G. Hairston) stated.that the hydrogen recombiner splices are to be left "as is" 'pending further study. A justification for continued operation was P

l

( _

provided to Region II on September 23, 1987, by APCo. Test results at Wyle Laboratory are underway now for fourteen configurations of "as found" splices at Farley, Results are expected in October 1987, with preliminary results in about a week.

APCo (R. Mcdonald) stated the following comitments to NRC:

1. APCo will not start up Unit 2 from its projected 52-day refueling outage starting on October 3, 1987, without assurance that APCo has resolved all operating issues on EQ matters (i.e., EQ issues which affect operability) for Unit 2 with the NRC.
2. APCo will keep the NRC advised of any emerging operating EQ issues found in either Unit 1 or 2 not addressed in the September 24, 1987 meeting.
3. APCo will not start up Unit 1 from the Spring 1988 refueling outage without reaffirming assurance that APCo has resolved all operating EQ  ;

issues involving Unit 1.

4. APCo will take appropriate action if an operating issue emerges at any time on Unit 1 or Unit 2. -

AFCo (W. Shipman) noted that the splice problem had occurred because of a field installation error in reading the design documents for " terminations" vice for " splices". Also, each splice had not been specifically identified on the EQ list of safety related components.

The NRC staff questioned various reasons why APCo took the actions to date.

The APCo staff responded to each question which was asked with specific l

emphasis on the logic involved in each action taken. APCo (J. Woodard) l sumarized that the Farley plants are considered to be safe to continue to

! operate as follows:

, 1. Pigtail splices are considered qualified.

2. Instruments inside containment are not expected to have pigtail splices.
3. No known pigtail splices exist inside containment.

)

i 4. Have not found a safety problem yet.

APCo (G. Hairston) stated that preliminary test results just received from 3 Wyle Laboratory indicate that the V-type, pigtail splices being tested appear to be acceptable. This preliminary report gives AFCo additional confidence.

NRC (Reeves) asked if APCo would expedite the walkdown inspections on Unit 2.

APCo responded that the walkdowns were scheduled for the entire outage period. This was of concern to the NRC staff since Unit I would continue operating for that length of time without knowing if other splice problems may exist there. APCo noted that they would take imediate action on Unit i for similar problems found on Unit 2 during the Unit 2 walkdowns.
