Supplemental Response to NRC Inspection Report 50-341/80-20 Page 2 of 4

'Ihis supplemental repcrt describes the additional action that has been taken on item 80-20-01 to address the additional concerns expressed by Mr. P.A. Barrett of NRC Region III. 'lhe actions described below are in addition to those previously reported in our report of January 23, 1981.

Statement of Violation 80-20, Appendix A, Item #1 (80-20-01)

Contrary to 10CFR50, Appendix B, Criterion II and the Enrico Fermi Unit 2-Quality Assurance Manual Section 1.0.1, quality control personnel of a contractor to Detroit Edison permitted instrunent cable installation activi-ties to continue before correcting a known deficiency in the pulling activi-ties. One cable had already been broken by these deficient activities. 'Ihis item is a severity Ievel IV violation.

Additional Corrective Action Taken and Results Achieved Item 2.a.

(Page 3 of Report)

(1) Determine how many other cables have been installed in this deficient manner and t uen ca m surate corrective action.

As stried in our previcus response, all Fermi 2 electrical cables pulled prior to the date of the NRC inspection were pulled using L.K. Cmstock' pulling instruction # 000-03-008 which was in use at the time of the inspecticm. Pulling records do not indicate those cables on which hand pulling was used. In addition to the cable testing described in our original response' Detroit Edison is taking the following additional action on this item.

Five cable samples have been selected and sent.to the Detroit Edison Research Laboratory for testing for cable darrage. 'Ihese sanples were taken frm the forward end (where maxinum tension would have occurred) of cables where pull links had broken and DDR's had been written. Should the test results indicate that cable damage occurred then additional action will be determined and taken at that time. If no prob 1ms are found the cables will be considered typical of those cables where pos-sible ver-tensioning has occurred.

(2) Document the stop work order issued on Novcurber 13, 1980 concerning these installation activities.

l The stop work order verbally issued on November 13, 1980 on hand pulling of cables was formerly issued on Ncv m ber 17, 1980. A copy of this document is on file and is available for review at the Fermi 2 Construc-tion Site.

l Corrective Action Taken to Avoid FtL@r Nonempliances Covered in the original response and no additional action was taken in this area.
