Subject:

Commonwealth Edison Company Commercial Service Date Forecast LaSalle County Station Units 1 and 2, Byron Station Units 1 and 2, Braidwood Station Units 1 and 2 NRC Docket Mos. 50-373/374, 50-454/455/456/457

Dear Mr. Denton:

Commonwealth Edison Company submits for your information the following update of scheduled commercial service dates for the subject units. In addition, the purpose of this letter is to clearly define our present expectations relative to the licensing review schedule for these units and to document our scheduled operating license (fuel load) dates.

The schedule commercial service dates set forth below reflect delays recently announced by the Company due to con-struction difficulties and to spread financing requirements more evenly through the five-year construction program in order to keep annual financing requirements within the Company's financial capabilities. They also reflect delays announced last year as a result of changes in the Nuclear Regulatory Commission's licensing schedules recommended by the Office of Nuclear Reactor Regulation of the MRC as a result of transfers of staff resources from licensing to the investigation of the Three Mile Island incident. The scheduled service dates set forth for the LaSalle County units also reflect delays announced last year resulting from construction changes, including re-visions in the design of the containments.

Mr. Harold R. Denton, Director June 20, 1980 Page 2 In addition, delineated below are the licensing re-view schedules for LaSalle County Unit 1 and Byron Unit 1 which are judged by Commonwealth Edison to be required to support the current fuel load schedule for those units. In this regard, the LaSalle County Unit 1 schedule is also applicable to LaSalle County Unit 2, and the Byron Unit 1 schedule is also applicable to Byron Unit 2 and Braidwood Units 1 and 2 LaSalle County Ul Byron Ul Current Revised Current Revised START Round One Questions --

l It is acknowledged that in the case of LaSalle County Unit 1 the scheduled fuel load date identified by the NRC Staff is two months later than that indicated by the applicant.

However, it is judged that these dates are so close that the difference is inconsequential for the purpose of scheduling both your resources as well as our own. In addition, from the standpoint of efficient utilization of engineers at both Commonwealth Edison and the NRC it is important that the licensing process'for both Byron and Braidwood proceed concurrently, as it has.

You may expect our. full cooperation and presentation of documents which should help you conduct the necessary reviews at LaSalle County, Byron and Braidwood Stations.

Should you have any questions please call or write this office.

Sincerely, ,
