REPLY TO NOTICE OF VIOLATION Inspection No. 50-334/88-21 Letter dated August 3, 1988 VIOLATION (Severity Level IV, Supplement I)

Description of Violation (88-21-01)

10 CFR 50.49(f) requires that qualification of each component be based on testing or experience with identical equipment or with similar equipment with a supporting analysis to show that the equipment to be qualified is acceptabl .

Beaver Valley site administrative procedure Chapter 31, Revision 2 Section 2a requires that equipment have sufficient documentation to establish that the equipment is environmentally qualifie Contrary to the above on May 12, 1988, the equipment qualification file 0044 Revision 3 for motor operated valve MOV-SI-885B did not have sufficient documentation to estcblish the qualification of Ideal Model wirenuts utilized in the motor stator wiring circui .

Admission or Denial of Alleged Violation The violation is correct as stated.

,

Reason for Violation During the performance of a routine Equipment Qualification (EQ)

inspection in April, 1987 for motor operated valve MOV-SI-885B, a motor lead wire was found damaged and had to be repaire The maintenance instructions / procedures used for the EQ inspection did not specifically addreas the repair of the particular Limitorque l wiring found to be damaged since this wa; not part of the preplanned inspectio Consequently, Maintenance obtained a wirenut which was stocked for use in safety related systems, but which was not approved for use in Electrical Equipment Qualification Master List (EEQML)

equipmen Approved methods for reconnecting / splicing wiring in EEQML equipment were in existence at that time and should have been use DLC believes the major contributing factor to the occurrence of this violation was a weakness on the part of the Maintenance and Quality Control personnel involved in understanding a certain aspect of the EQ progra Namely, the introduction of any new or different materials into equipment on the EEQML requires specific prior l approval by the Equipment Qualification Grou I

!

Corrective Steps Which Have Been Taken And Results Achieved j The wire nut for valve MOV-SI-885B was replaced with a qualified

'

compression crimp connector on May 12, 1988 via Maintenance Work Request 88302 ,

AEPLY.TO NOTICE OF VIOLATION

- Pags 2 m

To. a'scertain if the possibility existed of wirenuts being used in other EQ MOVs, a search of Maintenance Work Requests that may have involved wiring changes to MOVs was performed. We also inspected an additional 43 operators including 21 equipped with dual voltage motors for the presence of splice connectors other than T&B compression crimp connectors. As a result of these efforts one other wirenut installation was found in MOV-SI-864A. This wirenut was also replaced with a qualified crimp connector on May 13, 1988 via Maintenance Work Request 88301 Station procurement has removed wire nuts from stock for applications

, in safety related systems to preclude future misapplication of them in equipment on the Electrical Equipment Qualification Manter Lis Maintenance supervisors have been instructed to perform a timely post "

maintenance revicw of EQ maintenance work requests prior to turning the equipment over to operations to assure the equipment aas been properly repaired and restore A repeat training review of EQ maintenance requirements was conducted for Electrical Maintenance personnel on August 16 and September 1, 1988, emphasizing that to preserve environmental qualification, particular attention must be made not to introduce unqualified materials into the equipment or its interfaces which have been qualifie An 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> EQ seminar.for Quality Control inspectors and supervisors and Electrical Maintenance and Construction supervisors was given on August 17 and 18, 198 This additional training has resulted in a better understanding and heightened awareness of the combined effort required by Maintenance, Quality Control and Engineering to preserve the environmental qualificatica of the equipmen Corrective Steps Which Will Be Taken to Avoid Further Violations A review of Maintenance procedures is being conducted to identify any special requirements for qualified spare parts to preserve the qualification of the Limitorque Operator This review will be complated by September 30, 198 .

Additional EQ retraining classes will be held for those F,lectrical l Maintenance personnel who have been unable to attend ther. classes to '

dat We anticipate this will be completed by September 20, 198 l The Date When Full Compliance will be Achieved Full compliance has been achieve As noted above, the review of maintenance procedures and retraining should be completed by i september 30, 198 . - - , --. -.
