SUBJECT:

Technical Specification Change to Circulator Overspeed Trip Setting

REFERENCES:

(1) P-84112 (Warembourg to Wagner, Dated April 16, 1984)

Dear Mr. Collins:

This letter is to propose a change to the Circulator Speed-High Steam trip setting listed in Table 4.4-3 of the Fort St. Vrain Technical Specification (Attachment 1). The proposed increase in trip setting would increase circulator availability while still providing for initiation of the necessary protective actions prior to the maximum credible overspeed condition or the actions prior to the maximum credible overspeed condition or the blade shedding safety limit.

This new setting would avoid unnecessary actuations of the circulator protective circuitry due to normal system transients at or near 100%

power operation.

As evaluated in Attachment 2, the proposed change is deemed to involve no significant hazards considerations. Therefore, in accordance with 10 CFR 170, these changes are believed to be Fee Class III, and a check in the amount of $4,000.00 is enclosed.

If you have any questions, please contact Mr. Don Warembourg at (303) 785-2224.

Very truly yours, 7
