NUCLEAR REGULATORY COMMISSION
[Docket No. 72-25]
Foster Wheeler Environmental Corporation; Issuance of
Environmental Assessment and Finding of No Significant Impact Regarding
a Proposed Exemption
The U.S. Nuclear Regulatory Commission (NRC or the Commission) is
considering issuance of an exemption, pursuant to 10 CFR 72.7, from the
provisions of 10 CFR 72.102(f)(1) to Foster Wheeler Environmental
Corporation (FWENC or applicant). The requested exemption would allow
FWENC to use a probabilistic approach along with considerations of risk
to establish the design earthquake (DE) ground motion levels at the
Idaho Spent Fuel (ISF) Facility, instead of the deterministic
methodology of 10 CFR 100, Appendix A. FWENC submitted the exemption
request as part of its November 19, 2001, license application for the
ISF Facility, an independent spent fuel storage installation (ISFSI) to
be located at the Idaho National Engineering and Environmental
Laboratory (INEEL).
Environmental Assessment (EA)
Identification of Proposed Action: The applicant requested an
exemption from the requirement in 10 CFR 72.102(f)(1) which states
that, ``The design earthquake (DE) for use in the design of structures
must be determined as follows: (1) For sites that have been evaluated
under the criteria of Appendix A of 10 CFR Part 100, the DE must be
equivalent to the safe shutdown earthquake (SSE) for a nuclear power
plant.'' The regulation at 10 CFR 72.102(b) requires that, for sites
west of the Rocky Mountains, such as the ISF Facility site, seismicity
must be evaluated using the techniques of 10 CFR Part 100, Appendix A.
The requested exemption would allow the applicant to calculate the DE
for the proposed facility using an alternate method.
The proposed action before the Commission is whether to grant this
exemption pursuant to 10 CFR 72.7.
Need for the Proposed Action: The applicant has requested a license
to construct and operate the ISF Facility, as described in its license
application, dated November 19, 2001, on behalf of the Department of
Energy (DOE). FWENC will be the license holder for the ISF Facility,
which would be the second NRC-licensed ISFSI at the INEEL. The proposed
facility will be adjacent to the existing ISFSI for the TMI-2 fuel
debris, and close to the DOE facilities currently storing the spent
fuel to be moved to the ISF Facility. The ISF Facility represents an
additional milestone in the 1995 settlement agreement among DOE, the
U.S. Navy, and the State of Idaho regarding the disposition of spent
nuclear fuel at INEEL.
The exemption would allow the applicant to use risk-informed
methods including a probabilistic seismic hazards analysis (PSHA) to
define the design earthquake for the ISF Facility. This DE is a
critical assumption for the design of the facility structures, systems,
and components (SSCs) important to safety. These SSCs must be designed
to withstand the effects of natural phenomena, including earthquakes,
without impairing their capability to perform their safety functions.
For sites west of the Rocky Mountains, including the ISF Facility site,
10 CFR 72.102(b) requires that seismicity be evaluated using techniques
set forth in Appendix A of 10 CFR Part 100 for nuclear power plants. In
applying that appendix, the applicant would be required to define the
DE as the most significant earthquake postulated to occur at that site,
irrespective of its frequency, or the estimated time the facility would
be operational. This would result in unwarranted conservatism in the
design and construction of the facility, placing an unnecessary burden
on the applicant, increasing overall project costs and delaying
implementation of this phase of the settlement agreement between DOE
and the State of Idaho.
The NRC staff has evaluated the proposed exemption in its
preliminary safety evaluation report (SER) for the ISF Facility, dated
July 29, 2004. In the SER, the staff concludes that there are
sufficient technical and regulatory bases to grant an exemption to 10
CFR 72.102(f) at the time a license is issued for the ISF Facility.
These bases are that: (i) The probability and risk-informed analyses
performed by the applicant demonstrate that the SSCs important to
safety will maintain their capability to protect public health and
safety, even considering earthquake ground motions more severe than the
proposed DE; (ii) the applicant's exemption request is similar to
previous exemption requests found acceptable by the NRC staff for the
TMI-2 ISFSI and the Private Fuel Storage Facility; and (iii) the
applicant's methods and analyses are consistent with the probabilistic
approach and corresponding design earthquake values allowed under the
recently added regulations in 10 CFR 72.103, as described in the
associated regulatory guidance in NRC Regulatory Guide 3.73.
Environmental Impacts of the Proposed Action: The NRC staff
previously evaluated the environmental impacts resulting from the
construction, operation and decommissioning of the ISF Facility, and
determined that such impacts would be acceptably small. The staff's
conclusions are documented in the ``Environmental Impact Statement for
the Proposed Idaho Spent Fuel Facility at the Idaho National
Engineering and Environmental Laboratory in Butte County, Idaho (Final
Report), NUREG-1773,'' issued in
[[Page 55199]]
January 2004. In that environmental impact statement (EIS), and in the
preliminary SER, the staff considered the design earthquake for the
site based on the applicant's methods, and concluded that earthquake
events would not result in unacceptable consequences or significant
radiation releases from the proposed ISF Facility. Therefore, the staff
finds that the proposed exemption, involving the use of an acceptable
analytical method, will not have any significant environmental impact.
Alternative to the Proposed Action: As an alternative to the
proposed action, the staff considered denial of the proposed exemption
(i.e., the ``no-action'' alternative). Denial of the exemption request
would require the applicant to perform additional analyses and possibly
revise the design of the ISF Facility, but these changes would not
affect the conclusions of the EIS. Neither the proposed action nor the
alternative to the proposed action will have a significant
environmental impact. Therefore, the environmental impacts of the
proposed action and the alternative action are similar.
Agencies and Persons Consulted: On August 2, 2004, Mr. Doug Walker,
Senior Health Physicist with the State of Idaho INEEL Oversight
Program, was contacted regarding the environmental assessment for the
proposed exemption and had no comments. The NRC staff previously
evaluated the environmental impacts of the ISF Facility in the final
EIS issued in January 2004 and has determined that additional
consultation under Section 7 of the Endangered Species Act is not
required for this specific exemption which involves the use of an
alternative analytical method and will not affect listed species or
critical habitat. The NRC staff has similarly determined that the
proposed exemption is not a type of activity having the potential to
cause effects on historic properties. Therefore, no further
consultation is required under Section 106 of the National Historic
Preservation Act.
Finding of No Significant Impact
The environmental impacts of the proposed action have been reviewed
in accordance with the requirements set forth in 10 CFR Part 51. Based
upon the foregoing EA, the Commission finds that the proposed action of
granting the exemption from 10 CFR 72.102(f), so that FWENC may employ
alternative methods for determining the design earthquake for the ISF
Facility, will not significantly impact the quality of the human
environment. Accordingly, the Commission has determined that a Finding
of No Significant Impact is appropriate, and that an environmental
impact statement for the proposed exemption is not necessary.
For further details with respect to this exemption request, see the
FWENC license application for the ISF Facility, and the accompanying
Safety Analysis Report, dated November 19, 2001. The request for
exemption was docketed under 10 CFR Part 72, Docket No. 72-25. These
