Docket No. 50 '/53
Northern States Power Company
ATTN: Mr. C. E. Larson
Vice President, Nuclear
Generation
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.
