NUCLEAR REGULATORY COMMISSION
[Docket No. 50-219; NRC-2010-0200]
Exelon Generation Company, LLC Oyster Creek Nuclear Generating
Station Environmental Assessment and Finding of No Significant Impact
The U.S. Nuclear Regulatory Commission (NRC) is considering
issuance of exemptions from Title 10 of the Code of Federal Regulations
(10 CFR) Part 50, Appendix R, Section III.G, ``Fire Protection of Safe
Shutdown Capability,'' for Renewed Facility Operating License No. DPR-
16, for the use of operator manual actions in lieu of the requirements
specified in Section III.G.2, as requested by Exelon Generation
Company, LLC (the licensee), for operation of the Oyster Creek Nuclear
Generating Station (Oyster Creek), located in Ocean County, New Jersey.
Therefore, as required by 10 CFR Section 51.21, the NRC performed an
environmental assessment. Based on the results of the environmental
assessment, the NRC is issuing a finding of no significant impact.
Environmental Assessment
Identification of the Proposed Action
The proposed action would grant exemptions to 10 CFR Part 50,
Appendix R, Section III.G.2 based on 6 operator manual actions
contained in the licensee's Fire Protection Program (FPP). The
licensee's FPP requires that the identified operator manual actions be
performed outside of the control room to achieve shutdown following
fires in certain fire areas. The licensee states that each of the
manual actions was subjected to a manual action feasibility review for
Oyster Creek that determined that the manual actions are feasible and
can be reliably performed.
The proposed action is in accordance with the licensee's
application dated March 4, 2009 (available in the Agencywide Documents
Access and Management System (ADAMS) Accession No. ML090640225). By
letter dated April 2, 2010 (ADAMS Accession No. ML100920370), the
licensee submitted a response to an NRC staff request for additional
information. In this letter the licensee identified that, as a result
of clarifications included to Regulatory Guide 1.189, ``Fire Protection
for Nuclear Power Plants,'' some of the operator manual actions
included in the original exemption request no longer required an
exemption.
The Need for the Proposed Action
The proposed exemption from 10 CFR Part 50, Appendix R, was
submitted in response to the need for an exemption as identified by NRC
Regulatory Information Summary (RIS) 2006-10, ``Regulatory Expectations
with Appendix R Paragraph III.G.2 Operator Manual Actions.'' The RIS
noted that NRC inspections identified that some licensees had relied
upon operator manual actions, instead of the options specified in
Paragraph III.G.2 of 10 CFR Part 50, Appendix R, as a permanent
solution to resolve issues related to Thermo-Lag 330-1 fire barriers.
RIS 2006-10, however, identifies that an exemption under 10 CFR Section
50.12 is necessary for use of the manual actions in lieu of the
requirements of 10 CFR Part 50, Appendix R, III.G.2, even if the NRC
previously issued a Safety Evaluation that found the manual actions
acceptable. RIS 2006-10 and Enforcement Guidance Memorandum 07-004
(ADAMS Accession No. ML071830345) provided that exemption requests must
be submitted by March 6, 2009. The licensee's proposed exemption
provides the formal vehicle for NRC approval for the use of the
specified operator manual actions instead of the options specified in
10 CFR Part 50, Appendix R, III.G.2.
Environmental Impacts of the Proposed Action
The NRC has completed its evaluation of the proposed action and
concludes that the operator manual actions are procedural direction to
take actions proscribed for response to a fire-related event at the
plant and, therefore, cannot increase the probability of an event
occurring or introduce a new or different kind of event. The operator
manual actions restore or allow function of mitigative systems
necessary to place the plant in a safe-shutdown condition. Therefore,
the proposed action would not significantly increase the consequences
of accidents. No changes are being made in the types of effluents that
may be released off site. There is no significant increase in the
amount of any effluent released off site. None of the manual actions to
be performed are in areas that have radiation levels that would
preclude entry. Further, the licensee stated that the highest expected
dose during performance of the manual actions is 100 millirem (2
percent of the annual occupational limit), and the majority of manual
actions are not in radiological controlled areas. Based on this
consideration, the NRC staff finds that there is no significant
increase in occupational or public radiation exposure. Therefore, there
are no significant radiological impacts associated with the proposed
action. The NRC staff thus concludes that granting the proposed
exemption would result in no significant radiological environmental
impact.
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 or 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 noticeable effect on socioeconomic conditions in the region.
Therefore, no changes or different types of non-radiological
environmental impacts are expected as a result of the proposed action.
Accordingly, the NRC concludes 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 NRC 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 resources than
those previously considered in the 1974 Final Environmental Statement
for Oyster Creek and NUREG-1437, Vol. 1, Supplement 28, ``Generic
Environmental Impact Statement for License Renewal of Nuclear Plants
Regarding Oyster Creek Nuclear Generating Station, Final Report--Main
Report.''
Agencies and Persons Consulted
In accordance with its stated policy, on June 7, 2010, the NRC
staff consulted with the New Jersey State official for the
[[Page 33657]]
Department of Environmental Protection 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 March 4, 2009 (ADAMS Accession No.
ML090640225), as supplemented on April 2, 2010 (ADAMS Accession No.
ML100920370). Documents may be examined, and/or copied for a fee, at
