TEXAS UTILITIES ELECTRIC COMPANY ET AL*
DOCKET NO. 50-445 NOTICE OF ENVIRONMENTAL ASSESSMENT AND FINDING OF n
NO SIGNIFICANT IMPACT
~
4 The U. S. Nuclear Regulatory Commission (the Censnission) is considering 3
the issuance of an exemption from the requ'irements of 10 CFR 70.24 to Texas l
UtilitiesLiectricCompany,etal(theapplicant). The exemption would apply L
to the facility operating license for the Comanche Peak Steam Electric Station.
l Unit 1 (the facility) located on the applicant's site in Somervell county, Texas.-
ENVIRONMENTAL ASSESSMENT Identification of' Proposed Action: The proposed action would allow an exemption from the requirements of 10 CFR 70.24 for the operation of Comanche Peak, Unit 1 in response to the applicant's request dated June 30, 1989.
L l
l The current owners of the Comanche Peak Steam Electric Station are: Texas UtilitiesElectricComoany(TVElectric), Tex-LaElectricCoo Texas, Inc. (Tex-La), and Texas Municipal Power Agency (TMPA) perative of Transfer of ownership from TMPA to TV Electric was previously authorized by Amendment No. 9 to Construction Permit CPPR-126 for Comanche Peak, Unit 1 on August 25, 1988 to take place in 10 installments as set forth in the agreement attached to the application for amendment dated March 4,1988.
At the completion thereof, TMPA will no longer retain any ownership i
interest in Comanche Peak, Unit 1.
Transfer of ownership from Tex-La to TU Electric was previously authorized by Amendment No.11 to Construction Permit CPPR-126 for Comanche Peak, Unit 1 on August 29, 1989 as set forth in the agrt.ement attached to the application for Amendment dated May 4, 1989.
t At the completion thereof, Tex-La will no longer retain any ownership interest in Comanche Peak, Unit 1.

. The Need for the Proposed Action:
The exemption from 10 CFR 70.24 would L
allow irradiated or unirradiated fuel assemblies to be handled and stored in the Comanche Peak fuel handling building without having a monitoring system which will energize clearly audible alarms if accidental criticality occurs. This exemption will be deemed acceptable provided that no more than i
two fuel assemblies are outside.an approved shipping container, storage rack, or fuel transfer tube at any time and a minimum 12-inch, edge-to-edge t
distance is maintained between such assemblies. The proposed exemption is needed to permit fueling'and refueling operations at Comanche Peak without the criticality monitoring systems specified by 10 CFR 70.24(a).
Environmental Impacts of the Proposed Action: There are no environmental impacts of the proposed action.
Criticality will be precluded by the restriction that no more than two fuel assemblies shall be authorized to be outside of an approved shipping container, storage rack, or the fuel transfer tube at any one time and a minimum 12-inch, edge-to-edge distance is maintained between such assemblies. Because these measures provide assurance that criticality will not occur during receipt, inspection, or storage of fuel, this is an acceptable alternative to a monitoring system.
Since the proposed exemption does not otherwise affect radiological plant effluents nor cause any significant occupational exposures, the Commission concludes that there are no radiological environmental impacts associated with this proposed exemption.
With regard to potential non-radiological impacts, the proposed exemption involves systems located entirely within the restricted area as defined in 10 CFR Part 20. The proposed exemption does not affect non-radiological plant

L E effluente and has no'other environmental impact. Therefore, the Commission concludes that there are no significant non-radiological environmental impacts associated with the proposed exemption.
p Alternative to the Proposed Action: The Commission has concluded that there' are no measurable environmental impacts associated with the proposed exemption.
The principal alternative would be for the Comission to deny the requested exemption. This would not reduce the environmental impacts of the plant operation.
Alternative Use of Resources: This action ooes not involve the use of resources not previous 1,' considered in the Final Environmental Statement related to the r
operation of Comanche Peak Steam Electric Station, Units 1 and 2 (NUREG-0775),
dated September 1981.
Agencies and Persons Consulted: The NRC staff reviewed the applicant's request and applicable documents referenced therein that support this exetiption for Comanche Peak, Unit 1.
The NRC did not consult other agencies or persons in preparing this assessment.
FINDING 0F N0 SIGNIFICANT IMPACT l
The Commission has determined not to prepare an environmental impact statement for the proposed exemption.
Based upon the foregoing environmental assessment, the Commission concludes that the proposed action will not have significant effect on the quality of the human environment.
