UNITED STATES NUCLEAR REGULATORY COMMISSION COMMONWEALTH EDISON COMPANY DOCKET N05. 50-454 AND 50-455 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Comission (the Comission) is considering issuance of amendments to the licenses for the Comonwealth Edison Company (Ceco, the licensee) for Byron Station, Units 1 and 2, located in Ogle County, Illinois.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:
The proposed amendments would allow the use of Vantage 5 fuel.
These revisions to the licenses of Byron Station, Units 1 and 2, would be made in response to the licensee's application for amendment dated July 31, 1989.
l The Need For The Proposed Action:
l Pursuant to 10 CFR 50.90, the licensee has proposed amendments to Facility.
L Operating Licenses NPF-37 and NPF-66' for Byron Station, Units 1 and 2, L
respectively. The amendments would allow the use of Vantage 5 fuel.
l
.The Vantage 5 fuel design has already been approved by the NRC, with certain conditions and has several differences from the fuel currently being
~
used. These include:. integral burnable absorbers, intermediate flow mixer I
grids, reconstitutable top nozzle, extended burnup capability, exial blankets and debris filter bottom nozzle.
Environmental Impacts of the Proposed Action:
l-L
. The Comission has completed its evaluation of the proposed revision to the l
Technical Specifications. The loss-of-coolant accident was reanalyzed and the l

s.:
j results meet the criteria of 10 CFR 50.46. The proposed changes do not increase the probability or consequences of accidents, no changes are being made in the types of any effluents that may be released offsite, and there is no significant increase in the allowable. individual or cumulative occupational radiation exposure.
Accordingly, the Comission concludes that this proposed action would result in no significant radiological environmental impact.
With regard to nonradiological impacts, the proposed amendment involves systems located entirely within the restricted area as defined in 10 CFR Part
- 20. They do not affect nonradiological plant effluents and have no other environmental impact. Therefore, the Commission also concludes that there are no significant nonradiological environmental impacts associated with the proposed amendments.
Alternative to the proposed Actions:
Since the Comission concluded that there are no significant environmental effects that would result from the proposed action, any alternatives with equal or greater environmental impacts need not be evaluated.
The principal alternative would be to deny the requested amendment. This would not reduce environmental impacts of plant operation and would result in reduced operation flexibility.
Alternative Use of Resources:
This action does not involve the use of resources not previously considered in connection with the Nuclear Regulatory Comission's Final Environmental Statements for the Byron Station, Units 1 and 2 dated April 1982.

' Agencies and Persons Consulted:
~
The NRC staff reviewed the licensee's submittal of July 31, 1989 and did not
. consult other agencies or persons.
Finding of No Significant Impact:
i
' The Commission'has determined not to prepare an environmental impact statement-for the proposed license amendment, Based upon this environmental assessment, the Commission concludes that the' proposed action will not have a significant adverse effect'on the quality of the human environment.
~
The Notice of Consideration of Issuance of Amendment and Opportunity for-Hearing in connection with this action was published in the Federal Register on September 11,1989(54FR37518). No request for hearing or petition for leave to intervene was filed-following this notice.
