NUCLEAR REGULATORY COMMISSION
[Docket No. 50-443]
FPL Energy Seabrook, LLC, Seabrook Station Unit No. 1;
Environmental Assessment and Finding of No Significant Impact
The Nuclear Regulatory Commission (NRC or the Commission) is
considering issuance of an amendment pursuant to Title 10 of the Code
of Federal Regulations (10 CFR) part 50, for Facility Operating License
No. NPF-86 issued to FPL Energy Seabrook, LLC (the licensee), for
operation of Seabrook Station, Unit No. 1 (Seabrook), located in
Rockingham County, New Hampshire. Therefore, as required by 10 CFR
51.21, the NRC is issuing this environmental assessment and finding of
no significant impact.
Environmental Assessment
Identification of the Proposed Action
The proposed action would extend the expiration date of the
operating license for Seabrook from October 17, 2026, to March 15,
2030.
The proposed action is in accordance with the licensee's
application for amendment dated March 28, 2005, as supplemented
September 23, 2005.
The Need for the Proposed Action
The current operating licensed term for Seabrook ends on October
17, 2026. This is 40 years from the date of the zero-power operating
license, which was issued on October 17, 1986. The amendment would
extend the expiration date of the operating license from October 17,
2026, to March 15, 2030. The extended date for termination of the
operating license would be 40 years after issuance of the full-power
operating license which was issued on March 15, 1990. This would allow
the licensee to recapture approximately 41 months of additional plant
operation for the unit. This proposed amendment is not a request for
license renewal pursuant to 10 CFR Part 54.
Environmental Impacts of the Proposed Action
The NRC has completed its evaluation of the proposed action and
concludes that there are no significant environmental considerations
involved with the proposed action. The extension of the operating
licenses does not affect the design or operation of the plant, does not
involve any modifications to the plant or any increase in the licensed
power for the plant, and will not create any new or unreviewed
environmental impacts that were not considered in the Final
Environmental Statement (FES) related to the operation of Seabrook,
NUREG-0895, dated December 1982. The evaluations presented in the FES
were of the environmental impacts of generating power at Seabrook and
the basis for granting a 40-year operating license for Seabrook. The
environmental impacts of the proposed action are based on the
evaluations in the FES. It should be noted that the Seabrook license
was amended on February 28, 2005, to allow an increase in maximum core
power by 5.2% (from 3411 megawatts thermal (MWt) to 3587 MWt). The
environmental assessment of the power uprate was published in the
Federal Register on February 14, 2005 (70 FR 7525).
The FES which, in general, assesses various impacts associated with
operation of the facility in terms of annual impacts, and balances
these against the anticipated annual energy production benefits.
The offsite exposure from releases during postulated accidents has
been previously evaluated in the Updated Final Safety Analysis Report
(UFSAR) for Seabrook. The results are acceptable when compared with the
criteria defined in 10 CFR Part 100, as
[[Page 75488]]
documented in the Commission's Safety Evaluation Report, NUREG-0896,
dated March 1983, and its nine supplements. As a result of this action
there is no change in the types, frequency, or consequences of design-
basis accidents.
The NRC staff has concluded that the impacts associated with the
addition of approximately 41 months to the license expiration date are
not significantly different from the operating license duration
assessed in the Seabrook FES. Therefore, the staff concluded that the
FES sufficiently addresses the environmental impacts associated with a
full 40-year operating period for Seabrook.
The annual occupational exposure of workers at the plant, station
employees and contractors, is reported in the Annual Operating Report
submitted by the licensee. The lowest exposure value is for a year
without a refueling outage, and the highest value is for a year with a
refueling outage. In Section 5.9.3.1.1 of the FES, the average
occupational exposure for a pressurized water reactor was reported as
440 person-rems. Therefore, the expected annual occupational exposure
for the proposed extended period of operation does not change previous
conclusions presented in the FES on occupational exposure.
The offsite exposure from releases during routine operations has
been previously evaluated in Section 5.9.3 of the FES. During the low-
power license, the plant was restricted to no more than five percent of
rated power for no longer than 0.75 effective full power hours, and the
generation of radioactivity at the plant was significantly smaller than
would have occurred if the plant were at full-power operation.
Therefore, the addition of approximately 41 months of operation that
the licensee has requested does not change previous conclusions
presented in the FES on annual public doses.
The proposed action will not significantly increase the probability
or consequences of accidents, no changes are being made in the types of
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 have a potential to affect any historic sites. It does
not affect nonradiological plant effluents and has no other
environmental impact. Therefore, there are no significant
nonradiological environmental impacts associated with the proposed
action.
Accordingly, the NRC concluded that there are no significant
environmental impacts associated with the proposed action.
Environmental Impacts of the Alternatives to the Proposed Action
As an alternative to the proposed action, the staff considered
denial of the proposed action (i.e., the ``no-action'' alternative).
Denial of the application would result in no change in current
environmental impacts. The environmental impacts of the proposed action
and the alternative action are similar.
Alternative Use of Resources
The action does not involve the use of any different resource than
those previously considered in the FES for Seabrook.
Agencies and Persons Consulted
On December 8, 2005, the staff consulted with the New Hampshire
State official, Mr. Mike Nawoj, and the Massachusetts State official,
Mr. James Muckerheid, regarding the environmental impact of the
proposed action. The State officials had no comments.
Finding of No Significant Impact
On the basis of the environmental assessment, the NRC concluded
that the proposed action will not have a significant effect on the
quality of the human environment. Accordingly, the NRC has determined
not to prepare an environmental impact statement for the proposed
action.
For further details with respect to the proposed action, see the
licensee's letter dated March 28, 2005 as supplemented September 23,
2005. Documents may be examined, and/or copied for a fee, at the NRC's
Public Document Room (PDR), located at One White Flint North, Public
File Area O1 F21, 11555 Rockville Pike (first floor), Rockville,
Maryland. Publicly available records will be accessible electronically
from the Agencywide Documents Access and Management System (ADAMS)
Public Electronic Reading Room on the Internet at the NRC Web site,

access to ADAMS or who encounter problems in accessing the documents
located in ADAMS, should contact the NRC PDR reference staff by
