!

Mr. John Executive Vice President-Nuclear Northeast Nuclear Energy Company P.O. Box 270 Hartford, Connecticut 06141-0270

Dear Mr. Opeka:

SUBJECT: NRC SPECIAL INSPECTION 50-423/93-24 This refers to the special inspection conducted by Mr. P. Swetland and others of this office on August 28,1993, through November 8,1993, at Millstone Unit 3 in Waterford, ,

,

Connecticut. The inspection was conducted to review the circumstances surrounding your l identification of auxiliary building filter (ABF) system design deficiencies, which compromised the plant capability to establish a negative pressure inside the secondary containment following an accident. The preliminary findings were discussed with Mr. F.

l Dacimo and others of your staff at the conclusion of the inspection. Areas examined during the inspection are described in the enclosed report.

! During this inspection, we identified that your administrative process for assuring appropriate use of employee overtime was not strictly adhered to for individuals involved with the ABF system event review task force. A violation of NRC requirements concerning this problem is cited in the enclosed Notice of Violation.

Based on the results of this inspection, two apparent violations were identified and are being considered for escalated enforcement action in accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions" (Enforcement Policy),10 CFR Part ~2, Appendix C (1993). The apparent violations involved the inability of the ABF system to :

provide the necessary contribution to secondary containment draw down following a postulated accident, and your failure to identify and resolve these problems earlier, as a result of previous similar violations identified in September 1992. No Notice of Violation is presently being issued for these inspection findings. Please be advised that the number or i

characterization of apparent violations described in the enclosed inspection report may change

'

as a result of further NRC review.
