3) U.S. Atomic Energy Commission, "Final Environmental Statement Related to the Operation of the Vermont Yankee Nuclear Power Station, Docket No. 50-271," July 1972 In Reference 1, the NRC staff published the Draft Environmental Assessment and Finding of No Significant Impact (Draft EA) related to Entergy's request for a license amendment (Reference 2, as supplemented) to increase the maximum reactor power level of the Vermont Yankee Nuclear Power Station (VYNPS) from 1593 megawatts thermal (MWt) to 1912 MWt.

Entergy has completed its review of the Draft EA and has comments related to its content.

Those comments are provided as Attachment 1 to this letter.

An assessment of the environmental impacts of the proposed extended power uprate (EPU) was performed by Entergy as part of the license application. The assessment confirmed that the environmental effects of the proposed EPU are consistent with those determined in 1972 and documented in the original Final Environmental Statement (Reference 3). Entergy agrees with the NRC staff's analysis and conclusion documented in the Draft EA. That is, the proposed action will not have a significant effect on the quality of the human environment.

Attachment 1 to BVY 05-108 Docket No. 271 Page 1 of 1 ENTERGY COMMENTS ON THE DRAFT ENVIRONMENTAL ASSESSMENT FOR VERMONT YANKEE NUCLEAR POWER STATION RELATED TO EXTENDED POWER UPRATE No. Location (Federal Register page) I Text Entergy Comment 1 (68108) The "helper-cycle" mode of operation of the circulating "In the helper-cycle mode lof the water system is available; however, because of the circulating water system], only a portion provisions of the National Pollutant Discharge of the cooling water discharge flow is Elimination System (NPDES) Permit, the system is cycled through the cooling towers before operated in a 'hybrid" cycle as described in the being discharged to the Connecticut Vermont Yankee Nuclear Power Station (VYNPS)

River." Updated Final Safety Analysis Report (UFSAR) sections 11.6 and 11.9.

The circulating water system is designed to operate in any one of three modes of operation: open, closed, or hybrid cycle. In the hybrid cycle, all of the circulating water flow is cycled through the cooling towers, but only a portion is discharged to the river while the remainder is recycled.

The mode in which the circulating water system operates is a function of river temperature and flow.

2 (68108) Entergy does not own or maintain the transmission gEntergy's transmission line right-of-way lines. The lines are owned and operated by different maintenance praptices, including the transmission operators who ensure that proper ground i management of vegetation growth, would clearances are met.

I not change.d 3 (68108) It should be noted that Entergy's original environmental In the description of "Cooling Tower assessment for Extended Power Uprate (EPU) was Impacts." based on the use of 125 horsepower cooling tower fan motors. In fact, twenty-one of the twenty-two cooling tower fan motors were increased in size from 125 horsepower to 200 horsepower. This upgrade will improve cooling tower performance, and lessen aesthetic impacts due to plume size associated with increased cooling tower operation at EPU. The conclusions in the'Draft Environmrental Assessment regarding cooling tower operation (including noise) are correctly stated.
