Gentlemen:

Subject: NRC Region I Inspection No. 50-336/90-18 l

This letter transmits the results of the routine safety inspection conducted by

Mr. P. Habighorst of this office on August 22 - October 1, 1990, at Millstone

Nuclear Power Station, Unit 2, Waterford, Connecticut, of activities authorized

by HRC License No. DPR-65. Our findings were discussed by Mr. Habighorst with

Mr. J. Keenan and others of your staff at the conclusion of the inspection.

Areas examined during the inspection are described in the NRC Region I

inspection report which'is enclosed with this letter. Within these areas, the

inspection consisted of observation of activities, interviews with personnel,

and document reviews.

Based on the results of this inspection, it appears that certain of your

'

activities were not conducted in full compliance with NRC requirements, as set

forth in the Notice of Violation and in the Notice of Deviation enclosed here-

with as Appendices A.and B. The violation involves the-unavailability of the

reactor vessel level monitoring system during reduced inventory operation, and'

the deviation involves a failure to implement a commitment for the spent fuel

pool'boraflex coupon surveillance program. You are required to respond to this

letter, and in preparing your response, you should follow the instructions in

-Appendices A and B.

With regard to operational events that occurred during and shortly after this

inspection,;we are concerned by the number of problems noted with. personnel

performance, as identified in tagging errors, procedural non-adherence, and

inadequate configuration controls. The examples are highlighted in report

details _ 2.3.1, 2.3.2, 2.5, and 7.1. Another example of poor personnel per-

formance'that occurred after the inspection period involved the dropping of the

incore instrumentation plate. We request that you respond to this matter

within 30 days of your receipt of this letter.- In your response,.you should

address these personnel performance _ problems and describe the actions taken [

individually and collectively to prevent recurrence. 1
