k ATTACRMENT 1 SUPPLEMENTAL RESPONSE TO VIOLATION NO. 8912-02 INCIDENT NO.-2 Ac :tated in the original violation response, LP&L does acknowledge that a procedure / drawing discrepancy did exist at the time the splices for MS-416 were made. The specifics of this discrepancy were discussed in detail. It pas alto stated that. when the discrepancy was identified, Quality Notice QN No. QA-89-124 was femediately written.
In paragraph 5 of the original violation response, LP&L stated that procedure ME-4-809, Low Voltage (600 Volts and Less) Power and Control Cable / Conductor Terminations and Splices, Revision 4 would be revised to eliminate the noted conflict with drawing LOU-1564-B-288, sheet 40.
This was the proposed response to the QN as well as the planned corrective action to prevent recurrence.
From the time this discrepancy was diPcovered and until ME-4-809 could be revised, interim measures were implemented for splicing low voltage cables.
Maintenance planners were instructed by LP&L management to discontinue the use of, or reference to ME-4-809, Section 8.5 in work instructions for insulating splices. Work instructions were now to specify that all low voltage splices were to be made in accordance with the B-288 drawings.
An immediate revision to ME-4-809 was therefore not necessary because it would no longer be used to provide instructions for insulating low voltage splices.
On August 16, 1989, Revision 5 to ME-4-809 was issued. Section 8.5, which had been the insulating procedure, was deleted in its entirety. No further possibility now exists for a discrepancy between the instructions of procedure ME-4-809 and drawing LOU-1564-B-288, sheet 40.
All-future low voltage splices will be made solely in accordance vith the B-288 dcawings. Work instructions in all future Work Authorizations (WAs) will direct technicians to use only the current revisions of the B-288 drawings to' perform low voltage splices.
In Revision 4 of ME-4-809, Section 8.5.2 contained a note which stated,
" Filler shall not be required if totally impractical, such as with small-sized wire splices." At the time the splices for MS-416 were made.
Revision 4 of ME-4-809 was approved for use.
Based on this note, insulating tape (as a filler) was not used on the MS-416 splices. When Section 8.5 was deleted from ME-4-809 in Revision 5, the above note was also deleted.
Based on the above information, the low voltage splicing procedure / drawing discrepancies have been resolved and no further action is required.
