Docket No. 50-309

ATTN: Mr. John B. Randazza.

Augusta, Maine 04336
Gentlemen:
Subject:
Inspection 50-309/82-05
This letter refers to routine safety inspection conducted by Messrs. P. Swetland
and H. Gray of this office on March 23 - May 3, 1982 at the Maine Yankee
Nuclear Power Station, Wiscasset, Maine of activities authorized by NRC License
No. DPR-36 and to the discussions of our findings held by Mr. P. Swetland with
Mr. E. Wood of your staff at the conclusion of the inspection.
Apparent violations of NRC requirements.are discussed in the inspection report
enclosed with this letter. This report includes significant violations and we
are considering these items for appropriate enforcement action. We will be
addressing these mattcrs unde'r separate correspondence at a later time.
We .are concerned-with the apparent lack of management and procedural controls
in the areas'of design changes and modifications.
In one instance, a terminal
lug anchor nut, which is required to insure the operability of a safety injec-
tion system relay, was not installed during a system modification. This same
modification package had been the subject of Enforcement Action in our Inspec-
tion Report 82-04 forwarded to you by letter dated April 21, 1982. The current
finding and those identified in Report 82-04 regarding your control of safety-
related modifications are of concern.
We are further concerned with plant operations. The lack of management and
procedural controls in the area of plant operations has resulted in two recent
events involving written procedures which were inadequate. The first event
involved the failure to specify step-by-step adherence to the plant heatup
procedure and resulted in the draining of 5,000 gallons of radioactive
reactor coolant to a tank which was vented to atmosphere and which was
outside the area normally designated for control of contaminated water.
The excess capacity of the tank and prompt operator recognition and
corrective action prevented a release to the environment. This event was
aggravated, however, by the operators' failure to report the occurrence to
the NRC in a timely manner.
A second event resulted in a loss of containment integrity when two locked
closed, manual containment isolation valves for the steam generator blowdown
penetration were left open. We determined that procedural controls do not

address valve position status during the startup period. This event is
similar to that addressed in our inspection report 81-20, for which a civil
penalty was issued.
We consider the recurrent nature of events associated with design control,
modifications, and procedural compliance to be serious and believe that
improved management and procedural controls in these areas are necessary.
We have also concluded that a management conference is necessary. You will
be contacted subsequently regarding a mutually acceptable date and time for
the conference. At the conference, you should be prepared to discuss the
circumstances surrounding these' events, and your immediate corrective
actions.
In addition, you should also be prepared to discuss the controls
that are currently in place and those that are contemplated in order to
prevent future occurrences.
In accordance with 10 CFR 2.790(a), a copy of this letter and the enclosure
will be placed in the NRC Public Document Room unless you notify this
office, by telephone within 10 days of the date of this letter and submit
written application to withold information contained therein within thirty
days of the date of this letter. Such application must be consistent with
the requirements of 10 CFR 2.790(b)(1).
Your cooperation with us in this matter is appreciated.
Sincerely,
-
