NUCLEAR REGULATORY COMMISSION

[Docket Nos. STN 50-454 AND STN 50-456]


Commonwealth Edison Company; Notice of Withdrawal of Application 
for Amendment to Facility Operating Licenses

    The U.S. Nuclear Regulatory Commission (the Commission) has granted 
the request of Commonwealth Edison Company (the licensee) to withdraw 
its January 31, 1997, application for proposed amendments to Facility 
Operating License Nos. NPF-37 and NPF-66, for Byron Station, Units 1 
and 2, located in Ogle County, Illinois.
    The proposed amendment would have modified the facility technical 
specifications (TS) to reduce the Byron, Unit 1, limiting TS value for 
the primary coolant dose equivalent iodine-131 (DEI) concentration from 
0.35 to 0.20 microcuries per gram. The intent of this proposed TS 
revision was to limit the offsite dose at the exclusion area boundary 
to a small fraction of the radiation exposure guidelines in 10 CFR Part 
100. In the interim, ComEd performed an operability assessment and 
administratively reduced the Byron, Unit 1, DEI to 0.20 microcuries per 
gram. On November 7, 1997, ComEd started its Byron, Unit 1, fall 1997 
refueling outage during which the steam generators (SG) are being 
replaced. The replacement SG begin installed at Byron, Unit 1, will not 
have the relatively large end of cycle SG tube leakage attributed to 
the original SG. Accordingly, the license amendment requests submitted 
on January 31, 1997, was no longer needed.
    The Commission had previously issued a Notice of Consideration of 
Issuance of Amendment published in the Federal Register on March 12, 
1997, (62 FR 11489). However, by letter dated November 11, 1997, the 
licensee withdrew the proposed change.
    For further details with respect to this action, see the 
application for amendment dated January 31, 1997, and the licensee's 
letter dated November 11, 1997, which withdrew the application for the 
license amendments. The above documents are available for public 
inspection at the Commission's Public Document Room, the Gelman 
Building, 2120 L Street, NW., Washington, DC, and at the local public 
document room located at the Byron Public Library District, 109 N. 
Franklin, P.O. Box 434, Byron, Illinois 60481.

    Dated at Rockville, Maryland, this 8th day of January, 1998.

    For the Nuclear Regulatory Commission.

Senior Project Manager, Project Directorate III-2, Division of Reactor 
Projects--III/IV, Office of Nuclear Reactor Regulation
