SUBJECT:

BYRON STATION, UNITS 1 AND 2 WITHDRAWAL OF AN AMENDMENT REQUEST (TAC NO. M99535 AND M99536) .

Dear Mr. Kingsley:

By letter dated January 31,1997, Commonwealth Edison Company (Comed) applied for amendments to Byron Station, Units 1 and 2, Facility Operating License Nos. NPF 37 and NPF-66. The proposed change would have modified the facility to reduce the Byror, Station, Unit 1, lim't!ng TS value for the primary coolant dose equivalent lodine 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 being 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.

Sincerely, ORIGINAL SIGNED BY:
