Subject:

Byron Station Units 1 and 2 Application for Amendment to Facility Operating License, NPF-37, Appendix A, Technical Specifications NRC Docket Nos. 50-454/455 and 50-456/457

Dear Mr. Denton:

Pursuant to 10 CFR 50.90, Commonwealth Edison proposes to amend Appendix A, Technical Specifications to Facility Operating License NPF-37, to make several changes. Tnis change substitutes the requirement to measure source range neutron flux instrumentation high voltage plateau with discrimi-nator bias curves. These proposed changes are listed in Attachment 1, and further described in Attachment 2.

The proposed changes have been reviewed and approved by both On-site and Off-site review in accordance with Commonwealth Edison Company procedures. We have reviewed these proposed amendments in accordance with 10CFR 50.92(c) and determined that no significant hazards considerations exist. Our evaluation is documented in Attachment 3.

These changes are applicable to Byron Unit 2 and Braidwood Units 1 and 2 and should be incorporated into the initial Braidwood Technical Specifications, if they are found to be acceptable.

Commonwealth Edison is notifying the State of Illinois of our application for this amendment by transmitting a copy of this letter and its attachment to the designated state official.

In accordance with 10 CFR 170, a fee remittence in the amount of

$150.00 is also enclosed.
