Dear Mr. Stello:

In response to your request to provide you with a detailed schedule for our evaluation of asymmetric LOCA loads (Reference (b)) on Crystal River Unit 3, we have attached a report entitled, "B&W 177FA Owner's Group Asymmetric LOCA Loads Evaluation Program." The schedule presented is consistent with your intentions to resolve this issue within two years.

As can be determined from the report, we plan to evaluate the asymmetric loads issue in three distinct phases, with the execution of phases 2 and 3 being dependent upon the results of phase 1.

Only the details of the phase 1 evaluation have been included in the attached report.

Should we find'it necessary to proceed to phases 2 and 3, we will transmit detailed schedules and implementation plans to you in advance of executing these phases.

Please i;ote that we are engaged in the requested evaluation as a participant of the B&W 177 Fuel Assembly Owner's Group and, where permissible, plan to take advantage of generic analyses. When do mg so, we will provide justification for the generic jrouping.

If you have any further questions regarding this matter, please feel free to contact this office.

Very truly yours, FLORIDA POWER CORPORATION
