APPENDIX A NOTICE OF DEVIATION Boston Edison Company Docket No. 50-293 Pilgrim Nuclear Power Station License No. DPR-35 As a result of the inspection conducted on September 16-20, 1985, and in accordance with the NRC Enforcement Policy (10 CFR 2, Appendix C), the following Deviation was identified:

The licensee's May 18, 1982 letter (BECO Ltr. #82-145) to the NRC provided a description of his High Range Containment Monitoring System. This system is used to monitor Drywell and Torus Radiation levels during a Post-Accident situation. The radiation levels are used to estimate core damage. The attach-ment to the licensee's letter (Page 2, Design and Qualification) states in part that, "The coaxial cable used to carry the signal between the detectors and the Post-Accident Monitoring Panel is located in a harsh environment under accident conditions. ...The cable is installed in conduit ..."

Contrary to the above, a visual inspection of the detector cables by the NRC on September 19, 1985 found that an estimated 20-30 feet of cable for the redun-dant Drywell detectors, at the location where they entered the Drywell pene-trations, were not installed in conduit. The cable was found laying in an unprotected manner on various valves and pipes at that location.

Pursuant to the provisions of 10 CFR 2.201, Boston Edison Company is hereby required to submit to this office within thirty days of the date of the letter which transmitted this Notice, a written statement or explanation in reply, including: (1) the corrective steps which have been taken and the results achieved; (2) corrective steps which will be taken to avoid further violations; and (3) the date when full compliance will be achieved. Where good cause is shown, consideration will be given to extending this response time, f
