(c) Letter Florida Power Corp., to Victor Stello May 4, 1978, Asymmetric LOCA Loads, Phase 1.

Dear Mr. Stello:

Phase 1 of our asymmetric LOCA loads program that was outlined in our previous letter to you (Reference (c)) has been completed on Crystal River Unit 3.

That phase of our work has identified the need to proceed with less conservative approaches and, therefore, this letter submits our plan for proceeding with Phase 2.

The attached report entitled B&W 177 FA Owners Group Asymmt ' ric LOCA Loads Evaluation Program, Phase 2" identifies the content and schedule.

Please note that we are still engaged in the requested evaluation as a participant of the B&W 177 Fuel Assembly Owners Group and, where permissi-ble, plan to take advantage of generic analyses. When doing so, we will provide justification for the generic grouping.

At this time, the attached prograu addresses LOCA loads only.

How-ever, based on direction received from your Mr. Steve Hosford in a Decem-ber 12, 1978 meeting, we are now evaluating inclusion of seismic into the program. Until we have had time to evaluate the available seismic loads and develop a satisf actory seismic-LOCA load combination approach, we can-not define the seismic portion of the program.

These investigations.should be completed by mid-1979 and when a program is determined, additional information will be submitted.

If you have any fur *her questions regardi'g this matter, please con-tact this office.

Very truly yours, O
