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