Gentlemen:

Subject: NOTICE OF VIOLATION

(Inspection No. 50-423/86-39)

This refers to the NRC resident safety inspection conducted between December

29, 1986 and January 7, 1987 at the Millstone Nuclear Power Station, Unit 3,

Waterford, Connecticut. The inspection report was sent to you on January 21,

1987. During the inspection, NRC inspectors reviewed the circumstances

associated with a violation of a technical specification limiting condition for

operating (LCO) which was identified by a member of your staff and reported to

the NRC. The violation, which is described in the enclosed Notice, involved

the inoperability of one of the two safety injection systems. On February 27,

1987, an enforcement conference was conducted with you and members of your

staff to discuss the violations, their causes, and your corrective act'ons.

The one safety injection system (SI) was inoperable in that a service water

outlet vahe to the SI pump cooler was closed, thereby preventing the flow of

service cooling water to the pump cooler which in turn provides cooling for the

pump lubricating oil. As a result, the pump could have failed during opera-

tion. The valve was closed by a shift supervisor staff assistant (SSSA) during

a weekly test to determine fouling of the service water side of the heat

exchanger. However, the SSSA encountered difficulty in obtaining a needed

power supply, and he did not complete the test or reopen the valve.

The NRC is concerned that this SSSA, a recent college graduate with no prior

operating experience, was allowed to perform this test without adequate

training and supervision. Further, the test procedure was deficient in that it

did not: (1) specify that the valve would be manipulated; (2) require a valve

lineup verification; (3) require shift supervisor approval prior to

implementing; and (4) indicate that an LCO would be affected. As a result, the

individual manipulated plant equipment which affected a safety system, and the

shift supervisor was unaware of this activity. Manipulation of plant equipment

without the knowledge of the shift supervisor is a significant concern to the

NRC.

The NRC is also concerned that the SSSA had documented a record indicating

that the test was completed, even though the test had not been performed.

These events demonstrate the need for, and importance of, better review and

evaluation of procedures prior to approval, and enhanced training and super-

vision of employees, particularly those employees without any prior operating

experience, to ensure that performance of activities by these individuals does

not adversely affect operation of the facility. Therefore, although the vio-

lation nas been classified at Severity Level IV in accordance with the " General

Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2,

Appendix C (Enforcement Policy) (1986), we emphasize that any similar viola-

tions in the future may result in additional enforcement action.

You are required to respond to the enclosed Notice and, in preparing your res-

ponse, you should follow the instruction specified in the Notice. In your res-

ponse, you should document the actions taken or planned to prevent recurrence.

After reviewing your response to the Notice, including your proposed corrective

actions and the results of future inspections, the NRC will determine whether

further enforcement action is necessary to ensure compliance with NRC

regulatory requirements.

In accordance with 10 CFR 2.790, a copy of this letter and its enclosure will

be placed in the NRC Public Document Room.

The responses directed by this letter and the enclosed Notice are not subject

to the clearance procedures of the Office of Management and Budget, otherwise

required by the Paperwork Reduction Act of 1980, PL 96-511.

Sincerely,

William F. Kane, Director

Division of Reactor Projects
