Dear Dr. Murley:
Millstone Nuclear Power Station, Unit No. 3 Reporting of Potential Significant Deficiencies in Design and Construction:
Main Control Board Lugs (SD-48)
In a November 10,1983 telephone conversation between your Mr. T. Elsasser and our Mr. J. Festa, Northeast Nuclear Energy Company (NNECO) reported a potential significant deficiency in the construction of Millstone Unit No. 3 as required by 10CFR50.55(e).
The potential significant deficiency involves inadequate terminations of #14 AWG Tefzel and ITT Exane wire to AMP PIDG 53983-1 16-14 HD lugs in the main control board, supplied by Reliance Electric Company.
On January 9,1984, Reliance Electric Company, with the assistance of Stone &
Webster Engineering Corporation and Northeast Utilities, will initiate a 100%
inspection and repair program for all control boards supplied by Reliant e Electric.
This program will determine the corrective actions necessary to resolve this significant deficiency, as well as the completion date for its resolution.
As such, we are not able to provide you with a final report at this time.
However, we will provide you with an update on this matter on or before March 1,1983.
Very truly yours, W.S. &
