Mr. Harold R. Denton, Director Office of Nuclear Reactor Regulation U. S. Nuclear Regulatory Commission Washington, DC 20555

Subject:

Byron Station Units 1 and 2 Application for Amendment to Facility Operating Licenses NPF-37 and NPF-66, Appendix A, Technical Specifications NRC Docket Nos. 50-454 and 50-455 f

Dear Mr. Denton:

Pursuant to 10 CPR 50.90, Commonwealth Edison proposes to amend Appendix A, Technical Specifications, of Facility Operating Licenses NPF-37 and NPF-66. The proposed changes incorporate the addition of two radioactive liquid effluent monitoring instruments and the associated surveillance and sampling requirements into the Technical Specifications.

These instruments will provide monitoring and control of potentially radioactive liquid effluent releases to avoid exceeding the limits of 10 CPR Part 20. The proposed changes are contained in Attachment 1.

t 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 this proposed amendment in accordance with 10 CFR 50.92(c) and determined that no significant hazards considerations i exist. Our evaluation is documented in Attachment 2.

Commonwealth Edison is notifying the State of Illinois of our application for this amendment by transmitting a copy of this letter and its

~

attachments to the designated State Official.

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

$150.00 is enclosed.

CHANGE DESCRIPTIONS

1. Condensate Cleanup System Sump The Condensate Cleanup (CP) System was originally intended for use only during startup for system flushing, and therefore was not designed with provisions for monitoring radioactivity. Operating experience has indicated the need to run the system during normal plant operation. The potential therefore exists for low level radioactivity in the CP sump from regeneration effluent and system leakage. Because activity levels are anticipated normally to be negligible and water quality is expected to be acceptable for environmental discharge, sump discharge will be routed to the flume after being monitored. On detection of an unacceptable activity level, the added monitor will alarm, stop sump discharge, and terminate CP operation.

2. Fire and Oil Sump The original plant design for turbine building equipment and floor drains was to collect drain effluent into the oil separator, then route the separated water directly to the radwaste treatment system for processing and release via the release tank. The activity levels in the separated water are normally extremely low. Operating experience has indicated that the water volume is higher than originally anticipated, generating a heavy load for the radwaste treatment system for a negligible reduction in activity release. Therefore, it is intended that the separated water will be drained to the fire and oil sump, monitored for potential radioactivity, sent to the treated run-off system to ensure environmental standards are met, and then released to the flume. On detection of unacceptable activity levels, the monitor will alarm and automatically halt sump discharge.
