NUCLEAR REGULATORY COMMISSION
[Docket No. 50-322]
Environmental Assessment and Finding of No Significant Impact
Regarding Termination of the Shoreham Nuclear Power Station, Nuclear
Power Facility License No. NPF-82
The U.S. Nuclear Regulatory Commission is considering the issuance
of an Order modifying the June 11, 1992, Order (the decommissioning
Order) that authorized the Long Island Power Authority (LIPA or the
licensee) to decommission the Shoreham Nuclear Power Station (SNPS),
Unit 1, at Wading River, New York. The SNPS is located in the town of
Brookhaven, Suffolk County, New York, about 50 miles east of New York
City, on the north shore of Long Island. The modifying Order would
terminate License No. NPF-82 and release the site for unrestricted use
based on the successful completion of decommissioning.
Environmental Assessment
Identification of Proposed Action
By letter dated June 27, 1991, the former licensee, Long Island
Lighting Company (LILCO), and supplemented by letter dated August 4,
1994, the current licensee, LIPA, requested termination of the SNPS,
Nuclear Power Facility (NPF) License No. NPF-82 (Docket No. 50-322).
NRC approved, by Order dated June 11, 1992, the decommissioning of the
SNPS. The June 11, 1992, Order contained the staff's Environmental
Assessment and Finding of No Significant Impact related to the
decommissioning of SNPS.
The licensee has completed the decommissioning and Final
Termination Surveys of the SNPS. Representatives of the Oak Ridge
Institute for Science and Education (ORISE), under contract to NRC,
conducted a series of independent confirmatory surveys, during four
site visits from February 1993 through November 1994. The proposed
action would be to terminate the SNPS License No. NPF-82 and release
the facility and site for unrestricted use.
The Need for the Proposed Action
To release the SNPS for unrestricted access and use, License No.
NPF-82 must be terminated.
Environmental Impact of License Termination
In June 1992, NRC approved, by Order, the decommissioning of the
SNPS. The June 11, 1992, Order contained the staff's Environmental
Assessment and Finding of No Significant Impact related to the
decommissioning of SNPS.
Based on an agreement between the Philadelphia Electric Company
(PECo) and LIPA, the slightly irradiated fuel stored in the SNPS spent
fuel pool was transferred to the Limerick Generating Station for use.
The dismantlement and decontamination of the SNPS began in June 1992
and was completed in accordance with an approved decommissioning plan
(DP), as supplemented, in August 1994. All [[Page 18155]] contaminated
waste generated during the SNPS decommissioning has been removed from
the site.
The approved DP, as supplemented, contained the SNPS Final
Termination Survey Plan (Plan). The Plan described the methods used by
the licensee to demonstrate compliance with existing NRC unrestricted
release criteria. The guidelines used by the licensee for residual
radioactivity at the SNPS are consistent with the values provided in
Table 1, of Regulatory Guide 1.86, which establishes acceptable
residual surface contamination levels. NRC authorized alternative
contamination limits for iron-55 and tritium above those specified in
Regulatory Guide 1.86. These alternative criteria were presented to the
Commission in SECY 94-145 and increased the allowable residual average
and maximum total residual beta activity levels for iron-55 and tritium
from 5000 average total and 15,000 maximum total (fixed plus removable)
disintegrations per minute (dpm)/100 square centimeters to 200,000
average total and 600,000 maximum total dpm/100 square centimeters,
respectively. This permitted the licensee to safely retain on site
major portions of the reactor bioshield wall that did not exceed the
gamma dose rate criterion or the surface contamination limits for other
isotopes, but which would have required offsite disposal under the
original iron-55 and tritium surface contamination limits of Regulatory
Guide 1.86. A concentration limit for cobalt-60 in soil and other bulk
materials of 8 picocuries per gram was also established. An average
gamma dose rate criterion of 5 uR per hour above background, at a
distance of 1 meter from indoor accessible surfaces, was used. For
outdoor surfaces, individual gamma exposure rates are not to exceed 10
uR per hour above background at 1 meter.
The licensee implemented a phased approach to its Final Termination
Surveys and completed final radiological surveys in August 1994. These
survey measurements were verified by the NRC contractor, ORISE. The
ORISE confirmatory surveys confirmed that the licensee's measurements
meet the existing criteria for unrestricted release. Since the existing
unrestricted release criteria have been met, there is no significant
radiological impact on the environment from the release of the site.
With regard to potential non-radiological impacts, the proposed
action does not affect non-radiological plant effluents and has no
other environmental impact. Therefore, the NRC staff concludes no
significant non-radiological impacts are associated with the proposed
action.
In accordance with 10 CFR part 51, the Commission has determined
that the issuance of this termination Order is procedural in nature and
will have no significant impact on the quality of the human
environment. The proposed Order terminates the SNPS, Unit 1, Facility
License No. NPF-82.
Alternative to the Proposed Action
Since the NRC staff has concluded that there are no environmental
impacts associated with the proposed action, any alternative with equal
or greater environmental impacts need not be evaluated.
Agencies and Persons Consulted
The licensee initiated the request for termination of the SNPS
License No. NPF-82. The NRC staff reviewed the request and
representatives from ORISE performed confirmatory surveys. The staff
consulted with the State of New York regarding environmental impacts of
the proposed action, and the State did not provide any comments.
Finding of No Significant Impact
NRC has determined not to prepare an environmental impact statement
for the proposed action. Based on the foregoing environmental
assessment, NRC has concluded that the issuance of an Order will not
have a significant effect on the quality of the human environment.
