Subject:
Crystal River - Unit 3 Docket No. 50-302 Operating License No. DPR-72 IE Bulletin 79-02, Rev.1
Dear Mr. O'Reilly:
Enclosed is a supplement to our response of July 6,1979 to IE Bulletin 79-02, Rev. 1, dated June 21, 1979, which includes IE Bulletin 79-02.
We understand that for a system to be generally considered oper-able, all hangers must have a safety factor of 2:1 or greater.
Prior to entering MODE 2, Florida Power Corporation will upgrade all hangers with a safety factor of less than 2:1 to a safety factor of 4:1 or 5:1, as applicable, or will provide an analysis demonstrating the integrity, during the design basis earthquake (DBE) of each system that has a hanger with a safety factor of less than 2:1.
Furthormore, all accessible hangers with a safety factor of less than 4: 1 or 5:1, as applicable, will be upgraded to the appropriate safety factor as soon as possible.
The attached Table I identifies which hangers are inaccessible.
Table II identifies hanger changes required by design.
A mile-stone schedule for this repair will be submitted on or about July 20,1979.
All inaccessible hangers with a safety factor of less than 4:1 or 5:1, as applicable, will be upgraded to the appropriate safety factor i.aior to the startup after the next refueling outage.

Mr. J. P. O'Reilly Page 2 July 13,19M Florida Power Corporation has made a review of all hangers with a safety factor between 2 and 4 and established if any other such hangers are near. The basis of the review was that three hangers with a safety factor greater than four should be both upstream and downstream frm a hanger with a safety factor between 2 and 4.
All hangers with a safety factor less than 2 are assumed fixed.
(Previous Florida Power commitment.)
Florida Power further commits to make any repairs necessary to have 3 hangers with a safety factor greater than 4 both upstream and downstream of any hanger with a safety factor between 2 and 4.
These modifications will be complete prior to reaching Mode 2 operation.
Finally, the six (6) questions that were asked of FPC by the NRC during the telecon of July 6,1979, will be responded to on or about July 20, 1979.
If you have any further questions on this subject, please do not hesitate to contact me.
Sincerely, FLORIDA POWER CORPORATION l
