7590-01-P UNITED STATES NUCLEAR REGULATORY COMMISSION TEXAS UTILITIES ELECTRIC COMPANY DOCKET NOS. 50-445 AND 50-448 COMANCHE PEAK STEAM ELECTRIC STATION. UNITS 1 AND 2 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Commission (the Commission) is considering issuance of an exemption to Facility Operating License No. NPF-87 and NPF-89, issued to Texas Utilities Electric Company, (TU Electric, the licensee), for operation of the Comanche Peak Electric Station Steam Electric Station (CPSES), Units 1 and 2, located in Somervell County, Texas.
ENVIRONMENTAL ASSESSMENT Identification of the Proposed Action:
The proposed action would reduce the power level margin assumed for the emergency core cooling system analysis required by Title 10 of the Code of Federal Regulations. Part 50, Appendix K, based on the proposed use of a new feedwater flow measurement system (the Leading Edge Flowmeter system manufactured by Caldon, Inc.) to allow more accurate measurementof thermalpower.
The proposed action is in accordance with the licensee's application for exemption dated August 13,1998, as supplemented by letter dated December 17,1998.

2 The Need for the Proposed Action:
The proposed action will improve accuracy of thermal power measurement and support the licensee's separate request to increase licensed power level (which will be reviewed separately by the Commission).
Environmentallmoacts of the Proposed Action:
The Commission has completed its mNation of the proposed action and concludes that the proposad action w!!! not increase the probability or consequences of accidents, no changes are being made in the types of any effluents that may be released off site,'and there is no significant increase in occupational or public radiation exposure. Therefore, there are no significant radiological environmental impacts associated with the proposed action.
With regard to potential nonradiological impacts, the proposed action does not involve any
' historic sites. It does not affect nonradiological plant effluents and has no other environmental
.intpact. Therefore, there are no significant nonradiological environmental impacts associated with the proposed action.
Accordingly, the Commission concludes that there are no significant environmental impacts associated with the proposed action.
Altematives to the Proposed Action:
As an altamative to the proposed action, the staff considered dental of the proposed action (i.e., the "no-action" altomative). Denial of the application would result in no change in current environmentalimpacts. The environmentalimpacts of the proposed action and the altomative action are similar.
Altemative Use of Resources:
This action does not involve the use of any resources not previously considered in the Final Envitonmental Statement for the CPSES, dated October 1989.
