414 Nicollet Mall

Minneapolis, MN 55401

Gentlemen:

This refers to an Enforcement Conference conducted by Mr. C. E. Norelius and

other members of the Region III Staff with Mr. L. R. Eliason and your staff on

May 12, 1989.- The conference concerned operation of your facility with the

R2 actor Core Isolatien Cooling (RCIC) system inoperable by steam line flooding

while the High Pressure Coolant Injection (HPCI) system was declared inoperable.

We have concluded that the RCIC steam line flooding issue has resulted in a

Severity Level IV violation for failure to have adequate test controls. This

resulted in your failure to immediately begin a plant shutdown as required by

your Technical Specifications when RCIC and HPCI systems are inoperable. The

replacement of the limit switch assembly is viewed as untimely as evidenced by

previous unreliable operation. More prudent repair or replacement of this

switch was appropriate in this area. The prompt actions by your Shift Supervisor

to identify and correct the RCIC problem prevented the plant from exceeding the

twenty-four hour action statement requirement in your limiting condition for

operation (LC0).

A written response is required.

In your response, please include your actions;

to ensure operators are sensitive to the impact of test activities on equipment

operability, and to ensure prudent actions to fix unreliable equipment are

implemented promptly.

In accordance with 10 CFR 2.790 of the Commission's regulations, a. copy of

this letter, the enclosures, and your response to this letter will be placed

in the NRC Public Document Room.

The responses directed by this letter and the accompanying Notice are not

subject to the clearance procedures of the Office of Management and Budget as

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