Dear Mr. Case:
This letter is in response to Mr. Don K. Davis'etter. of November 28, 1977 concerning the limiting heatup rate of the pressurizer.
We have conducted a review of our operating records at the Donald C.
Cook Nuclear Plant Unit No.
1 subsequent, to the receipt, of Mr. Davis'etter.
This review indicates that, the re-quired pressurizer heatup rate of 100 F/hour has never been ex-ceeded during the course of any plant startup.
The maximum heat-up rate, with all heaters in service, was 67.5 F/hour.
Plant operating procedures were revised to require a limit-ing pressurizer heatup rate of 100 F/hour, subsequent to noti-fication from Westinghouse.
Amendment No.
23 to the Unit, No.
1 Technical Specifications includes a revision to require the limit-ing pressurizer heatup rate of 100 F/hour.
Ver truly yours, JT em
