Gentlemen:
Subject: Millstone 3 Routine Inspection 50-423/87-24 (11/3/87-12/07/87)
This refers to the routine resident safety inspection conducted on November 3
- December 7, 1987, at the Millstone Nuclear Power Station, Unit 3.
The
results of the inspection are described in the NRC Region I Inspection Report
enclosed with this letter and were discussed with Mr. C. H. Clement of your
staff at the conclusion of the inspection.
No violations were identified during this inspection and no reply to this
letter is required. However, we are concerned about your follow-up and root
cause identification of events which led to abnormal sodium concentration in
the refueling water storage tank and the reactor coolant system (Detail 9) and
your lack of boundary valve control during cavity draining (Detail 10). We
will follow your corrective actions for these.
Your cooperation with us is appreciated.
Sincerely,
6:.
