~ UNITED STATES NUCLEAR REGULATORY COPMISSION NORTHEAST NUCLEAR ENERGY COMPANY, ET AL.

MILLSTONE NUCLEAR POWER STATION, UNIT NO. 2 DOCKET NO. 50-336

-NOTICE OF ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT L

l The U. S. Nuclear Regulatory Connission (the Consnission) is considering

~

issuance of an amendment to Operating License No. DPR-65 to Northeast Nuclear -

i Energy Company, et al., (the licensee) for Millstone Unit No. 2 located in Waterford, Connecticut.

Identification of Proposed Action: The amendment would consist of changes

~

to the operating license and Technical Specifications (TS) and would i

authorize an increase of the storage capacity of the spent fuel pool (SFP)

I from 667 fuel assemblies to 1112 fuel assemblies with enrichments no greater j

f than 4.5 weight percent U-235.

The amendment to the TS is responsive to the licensee's application dated July 24, 1985. The NRC staff has prepared an Environmental Assessment l

of the proposed action, " Environmental Assessment By the Office of Nuclear i

Reactor Regulation Relating to the Modification of the Spent Fuel Storage i

Pool, Operating License No. DPR-65, Northeast Nuclear Energy Company, et al.,

Millstone Unit No. 2 Docket No. 50-336" dated Summary of Environmental Assessment: The Final Generic Environmental Impact 4

l Statement (FGEIS) on Handling and Storage of Spent Light Water Power Reactor Fuel (NUREG-0575) concluded that the environmental impact of interim storage i

of spent fuel was negligible and the cost of the various alternatives reflects P

~

2 the advantage of continued generation of nuclear power with the accompanying spent fuel storage. Because of the differences in SFP designs, the FGEIS i

recommended licensing SFP expansion on a case-by-case basis.

j For Millstone Unit 2, the expansion of the storage capacity of the SFP will not create any significant additional radiological effects or measurable non-radiological environmental impacts. The additional total body dose that might be received by an individual at the site boundary is less than 0.1 millrem per year; the estimated dose to the population within an 80 kilometer radius of the plant is estimated to be less than 0.1 person-rem per year.

These doses are small compared to the fluctuations in the annual dose this population receives from exposure to the background radiation. The total occupational exposure for the reracking and the additional occupational exposure for the subsequent operation of the modified SFP is less than 2% of the average annual occupational dose of 500 person-rems for all plant operations at Millstone Unit 2.

Therefore, the staff concludes that the exposure to workers is as low as is reasonably achievable (ALARA) and is

(

acceptable.

i Findino Of No Significant Impact: The staff has reviewed this proposed I

facility modification relative to the requirements set forth in 10 CFR Part 51.

Based upon the environmental assessment, the staff concluded that there are no significant radiological or non-radiological impacts associated with the proposed action and that the proposed license amendment will not have a significant effect on the quality of the human environment. Therefore, the Commission has determined, pursuant to 10 CFR 51.31, not to prepare an environmental impact statement for the proposed amendment.
