Subject:
Crystal River Unit 3 Docket No. 50-302 Operating License No. DPR-72 Rupture Matrix Signals
Dear Mr. Stolz:
Enclosed are forty (40) copies of the report " Evaluation of Reactivity Response For a Steam Line Break Event With Unterminated Emergency Feedwater Flow." This report provides an analysis which d' monstrates that a return to criticality will not occur.
No changes to the Technical Specifications or the FSAR are required.
This report satisfies the final concerns with respect to our June 2,1980, submittal, " Evaluation of Steam Line Break Con-sequences Associated With Renoval of Eupture Matrix Signals From Emergency Feedwater Valves," and Conmitment Item 51 in Enclosure B of our May 2,1980 submittal.
This report also satilifies the final concern of not isolating emergency feedwater via the rupture matrix stated in Florida Power Corpora-tion s response to Question 1 of I.E.Bulletin 80-04.
Florida Power Corpo-ration requests concurrence by October 15, 1981, as stated in our response to 1.E.Bulletin 80-04, to remove valves FWV-161 and FWV-162 from the rup-ture matrix actuation logic. A substantial improvement in secondary cooling relicbility can be achieved by removing the automatic actuation of these valves.
In letters dated June 18, 1980, and July 30, 1980, the NRC informed Florida Power Corporation that the evaluation of our June 2, 1980, submittal was subject to the requirements of 10 CFR 170.22, and requested a Class III fee 1

Then in a telephone conversation on July 31, 1980, between Mr. P. Erickson of-the NRC, and Mr. R. Bright of Florida Power Corporation, the payment of $4,000 was agreed to be provided when Florida Power Corporation submitted the final analysis. Enclosed is a check for $4,000.
