Docket No. 50-423
Northeast Nuclear Energy Company
ATTN: Mr. J. F. Opeka
Senior Vice President - Nuclear
Engineering and Operations Group
P. O. Box 270
Hartford, Connecticut 06101
Gentlemen:
Subject: Inspection Report No. 50-423/85-54
This refers to the As-Built Team inspection conducted by Mr. J. T. Wiggins of
this office on September 9-20, 1985, at the Millstone Nuclear Power Station,
Unit 3, Waterford, Connecticut, of activities authorized by NRC License No.
CPPR-113 and to the discussions of our findings held by Mr. J. Wiggins with
Messrs. J. Crockett, L. Nadeau, and V. Papadopoli at the conclusion of the
inspection.
Areas examined during this inspection are described in the NRC Region !
Inspection Report which is enclosed with this letter. Within these areas, the
inspection consisted of selective examinations of procedures and representative
records, interviews with personnel, measurements and calculations made by the
inspectors, and observations by the inspectors.
Within the scope of this inspection, no violations were observed.
In fact,
the-inspection demonstrated that the systems examined were constructed
substantially in accordance with the descriptions provided in the Final Safety
Analysis Report.
Independent calculations performed by the NRC staff indicate that the air
storage bottle capacity, required for control room pressurization and habit-
ability, is marginal and may not be able to adequately compensate for the
assumed control room leak rate specified in Section 6.4 of NUREG-1031, Safety
Evaluation Report (SER) for Millstone 3.
You should address this concern and
assure that the system design envelope is consistent with the SER and plant
Technical Specifications.
