NUCLEAR REGULATORY COMMISSION
[Docket No. 50-400; NRC-2010-0020]
Carolina Power & Light Company Shearon Harris Nuclear Power
Plant, Unit 1; Environmental Assessment and Finding of No Significant
Impact
The U.S. Nuclear Regulatory Commission (NRC, the Commission) is
considering issuance of an exemption, pursuant to title 10 of the Code
of Federal Regulations (10 CFR) section 73.5, ``Specific exemptions,''
from the implementation date for certain requirements of 10 CFR part
73, ``Physical protection of plants and materials,'' for Renewed
Facility Operating License No. NPF-63, issued to Carolina Power & Light
Company (the licensee), now doing business as Progress Energy
Carolinas, Inc., for operation of the Shearon Harris Nuclear Power
Plant (HNP), Unit 1, located in New Hill, North Carolina. In accordance
with 10 CFR 51.21, the NRC staff prepared an environmental assessment
documenting its finding. The NRC staff concluded that the proposed
actions will have no significant environmental impact.
Environmental Assessment
Identification of the Proposed Action
The proposed action would exempt the licensee from the required
implementation date of March 31, 2010, for one specific requirement of
10 CFR part 73. Specifically, HNP, Unit 1 would be granted a second
exemption, further extending the date for compliance with one remaining
item of the requirements contained in 10 CFR 73.55, from December 15,
2010, (the date specified in a prior exemption granted by NRC on
February 24, 2010), until November 30, 2011. The proposed action, an
extension of the schedule for completion of certain actions required by
the revised 10 CFR part 73, does not result in any additional physical
changes to the reactor, fuel, plant structures, support structures,
water, or land at the HNP, Unit 1 site.
The proposed action is in accordance with the licensee's
application dated September 20, 2010.
The Need for the Proposed Action
The proposed exemption is needed to provide the licensee with
additional time, beyond the date granted by the NRC letter dated
February 24, 2010, to implement one remaining item of the three
requirements in the previous exemption that involves important physical
modifications to the HNP, Unit 1 security system. There are several
issues which have delayed the work to this point, and/or impacted the
projected schedule, such as the existence of safety-related conduit and
dedicated safe shut down (SSD) equipment of HNP, Unit 1 within the room
in which some important security modifications are planned. A direct
outside access route to the physical construction area has not been
available due to design basis tornado and missile considerations for
the safety related conduits and SSD equipment. These issues were
revealed as the design evolved from the conceptual state to a detailed
design state. Presently, the licensee is pursuing a design solution
that will allow both temporary and ultimately permanent direct outside
access to the area. Additional time, beyond that previously approved,
is needed due the extensive redesign and review effort that was
unforeseen at the conceptual design stage.
Environmental Impacts of the Proposed Action
The NRC staff has completed its environmental assessment of the
proposed exemption. The NRC staff has concluded that the proposed
action to further extend the implementation deadline for one item would
not significantly affect plant safety and would not have a significant
adverse effect on the probability of an accident occurring.
The proposed action would not result in an increased radiological
hazard beyond those hazards previously analyzed in the environmental
assessment and final finding of no significant impact made by the
Commission in promulgating its revisions to 10 CFR part 73 as discussed
in a Federal Register notice dated March 27, 2009 (74 FR 13926). There
will be no change to radioactive effluents that affect radiation
exposures to plant workers and members of the public. Therefore, no
changes or different types of radiological impacts are expected as a
result of the proposed exemption.
The proposed action does not result in changes to land use or water
use, or result in changes to the quality or quantity of non-
radiological effluents. No changes to the National Pollution Discharge
Elimination System permit are needed. No effects on the aquatic or
terrestrial habitat in the vicinity of the plant, or to threatened,
endangered, or protected species under the Endangered Species Act, or
impacts to essential fish habitat covered by the Magnuson-Stevens Act
are expected. There are no impacts to the air or ambient air quality.
There are no impacts to historical and cultural resources. There
would be no impact to socioeconomic resources. Therefore, no changes to
or different types of non-radiological environmental impacts are
expected as a result of the proposed exemption.
Accordingly, the NRC concludes that there are no significant
environmental impacts associated with the proposed action.
With its request to extend the implementation deadline, the
licensee currently maintains a security system acceptable to the NRC
and that will continue to provide acceptable physical protection of
HNP, Unit 1 in lieu of the new requirements in 10 CFR part 73.
Therefore, the extension of the implementation date for one element of
the new requirements of 10 CFR part 73 to November 30, 2011, would not
have any significant environmental impacts.
The NRC staff's safety evaluation will be provided in the exemption
that will
[[Page 77920]]
be issued as part of the letter to the licensee approving the exemption
to the regulation, if granted.
Environmental Impacts of the Alternatives to the Proposed Action
As an alternative to the proposed actions, the NRC staff considered
denial of the proposed action (i.e., the ``no-action'' alternative).
Denial of the exemption request would result in no change in current
environmental impacts. If the proposed action was denied, the licensee
would have to comply with the existing implementation deadline of
December 15, 2010, for one remaining item of the three requirements, as
granted on February 24, 2010. The environmental impacts of the proposed
exemption and the ``no-action'' alternative are similar.
Alternative Use of Resources
The action does not involve the use of any different resources than
those considered in the Final Environmental Statement for HNP, Unit 1,
NUREG-0972, dated October 31, 1983, as supplemented through the
``Generic Environmental Impact Statement for License Renewal of Nuclear
Plants: Regarding Shearon Harris Nuclear Power Plant, Unit 1--Final
Report (NUREG-1437, Supplement 33).''
Agencies and Persons Consulted
In accordance with its stated policy, on December 2, 2010, the NRC
staff consulted with the North Carolina State official,
[email protected] of the North Carolina Department of Environment and
Natural Resources, regarding the environmental impact of the proposed
action. The State official had no comments.
Finding of No Significant Impact
On the basis of the environmental assessment, the NRC concludes
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 September 20, 2010. Portions of the September
20, 2010, submittal contain security-related information and,
accordingly, a redacted version of this letter is available for public
review in the Agencywide Documents Access and Management System
