SUPPLEMENTARY INFORMATION: The U.S. Nuclear Regulatory Commission (NRC
or the Commission) is considering renewing Virginia Electric and Power
Company's (Dominion's) (the applicant's) License No. SNM-2501 under the
requirements of Title 10 of the Code of Federal Regulations, Part 72
(10 CFR Part 72) authorizing the continued operation of the Surry
Independent Spent Fuel Storage Installation (ISFSI) located at the
Surry Power Station in Surry County, Virginia. The Commission's Office
of Nuclear Material Safety and Safeguards has completed its review of
the environmental report submitted by the applicant on April 29, 2002,
in support of its application for a renewed materials license. The
staff's ``Environmental Assessment related to the renewal of the Surry
Independent Spent Fuel Storage Installation'' has been issued in
accordance with 10 CFR Part 51.
I. Summary of Environmental Assessment (EA)
Description of the Proposed Action: The proposed licensing action
would authorize the applicant to continue operating a dry storage ISFSI
at the Surry site. The purpose of the ISFSI is to allow for interim
spent fuel storage and, indirectly, power generation capability, beyond
the term of the current ISFSI license to meet future power generation
needs. The current license will expire July 31, 2006. The renewed ISFSI
license would permit 40 additional years of storage beyond the current
license period. The current ISFSI employs five different cask systems
licensed for the Surry ISFSI. These cask systems include the General
Nuclear Systems, Inc., (GNSI) CASTOR V/21 and CASTOR X/33, the
Westinghouse MC-10, the NAC INTACT 28 S/T, and the Transnuclear, Inc.,
TN-32. Currently, the facility is licensed to store spent fuel storage
casks on three reinforced concrete pads that are 230 feet long, 32 feet
wide, and 3 feet thick. Two of the three storage pads have been built.
Each pad is designed to accommodate 28 casks.
Need for the Proposed Action: The Surry ISFSI is needed to provide
continued spent fuel storage capacity so that the Surry Power Station
can continue to generate electricity. This renewal is needed to provide
an option that allows for interim spent fuel storage and, indirectly,
power generation capability, beyond the term of the current ISFSI
license to meet future system generating needs. The renewed ISFSI
license would permit 20 additional years of storage beyond the current
license period. An exemption would allow 20 years of storage beyond the
renewal period.
Environmental Impacts of the Proposed Action: The NRC staff has
concluded that the license renewal of the Surry ISFSI will not result
in a significant impact to the environment. The Surry ISFSI will
require one additional storage pad during the license renewal term. The
pad would be built on previously disturbed ground adjacent to the
existing pads. Construction impacts of the third storage pad of the
ISFSI will be minor, and limited to the approximately 800 feet by 800
feet ISFSI site. No areas designated by the U.S. Fish and Wildlife
Service as ``critical habitat'' for endangered species exist at the
site. The only terrestrial community at the site consist of remnants of
mixed pine-hardwood forest that were used for timber production prior
to the site's acquisition by Dominion. Thus, the staff does not expect
the ISFSI to impact any threatened or endangered species. The
Environmental Assessment for the ISFSI construction acknowledged that
although the station was located in a historic region, no historical
resources were identified within the boundaries of the site. During the
Surry Power Station license renewal process, Dominion commissioned a
cultural resource survey of the property. The survey identified one
previously recorded archaeological site on the west side of the
property and classified the remainder of the property into one of three
categories, based on the potential for archaeological resources. The
ISFSI, because it rests on previously disturbed land, was classified as
having no potential for cultural resources.
There will be no significant radiological or non-radiological
environmental impacts from routine operation of the ISFSI. The staff
evaluated radiological impacts from operations to ensure that the
radiation dose to both workers and the public is as low as reasonably
achievable (ALARA). The Surry Power Station ALARA program, including
ISFSI operations, complies with 10 CFR Part 20, Radiation Protection
Programs, and is consistent with Regulatory Guide 8.8, ``Information
Relevant to Ensuring That Occupational Radiation Exposures at Nuclear
Power Stations Will Be As Low As Reasonably Achievable.''
There are several parks and preserves in Surry County, primarily
along the south bank of the James River. Immediately adjacent to the
Surry Power Station is the Hog Island tract of Hog Island Wildlife
Management Area (HIWMA) (zoned A-R), at the north end of the peninsula
on which the Surry Power Station is located. In addition, south of the
Surry Power Station are the Carlisle and Stewart tracts of HIWMA. West
of the Surry Power Station, bordering the James River, is Chippokes
Plantation State Park, and further west are Swanns Point and Pipsico
Reservations.
The ISFSI licensing basis for the annual dose to the nearest
permanent resident, located 1.53 miles from the ISFSI, was based on 84
GNSI CASTOR V/21 casks. The annual dose calculated for that case was
6.0x10-5 mrem, which is well below the 10 CFR 72.104 and 10
CFR 20.1101 limits. The revised calculations based on 84 TN-32 casks
results in a dose of 5.6x10-5 mrem per year, which is less
than the original licensing basis. The staff reviewed the calculations
and assumptions provided by Dominion. Based on these results, normal
ISFSI operations will not have a significant offsite radiological
impact and will remain well within the 10 CFR 20.1101 and 72.104
limits. The staff also evaluated radiological consequences of a release
of the entire gaseous inventory of a cask and found that Dominion's
calculated dose to an individual at the nearest site boundary is 84
mrem, which is well within the 5 rem criteria of 10 CFR 72.106.
The annual collective dose from 84 TN-32 casks to 48 residents
within a two-mile radius of the ISFSI is calculated to be
2.7x10-6 person-rem, which is several orders of magnitude
less than the collective dose from natural background radiation.
Radiological decommissioning of the ISFSI would be complete when
the last cask is removed from the site. Small occupational exposures to
workers
[[Page 9115]]
could occur during decontamination activities, but these exposures
would be much less than those associated with cask loading and transfer
operations. Due to the design of the sealed surface storage casks, no
residual contamination is expected to be left behind on the concrete
base pad. The base pad, fence, and peripheral utility structures are
defacto decommissioned when the last cask is removed.
Alternatives to the Proposed Action: The applicant's Environmental
Report and the staff's EA discuss several alternatives to the proposed
ISFSI license renewal. These alternatives include shipment of spent
fuel off-site, and other methods to increase on-site spent fuel storage
capacity, as well as the no action alternative. In the first category,
the alternatives of shipping spent fuel from Surry to a permanent
Federal Repository, to a reprocessing facility, or to a privately owned
spent fuel storage facility were determined to be non-viable
alternatives, as no such facilities are currently available in the
United States, and shipping the spent fuel to other power stations is
impractical because the receiving utility would have to be licensed to
store the Surry spent fuel, and it is unlikely that another utility
would be willing to accept it, in light of their own limitations on
spent fuel storage capacity. Another off-site alternative is to
construct an ISFSI at a site away from the Surry Power Station.
However, it was concluded that this alternative does not offer net
environmental benefits
Other on-site storage alternatives considered by the applicant
included increasing the capacity of the existing spent fuel pools by
re-racking or spent fuel rod consolidation, or construction of a new
spent fuel storage pool. Dominion has already increased the original
capacity of the existing pool and cannot increase it further. Although
the applicant could construct an additional spent fuel pool, the high
cost associated with constructing and maintaining such a facility and
all of the necessary support equipment, coupled with the significant
occupational exposures resulting from the extensive fuel handling
operations, make this alternative impractical. Modifying operations of
the plants was also considered such as extending fuel burnup or
operating at reduced power. However, such operational changes may alter
the amount of fuel to be stored, but they do not eliminate the need for
storage. Also, consideration of researching other technologies for
interim disposal was determined non-viable because of additional doses
associated with repackaging.
The no action alternative could result in the extended or permanent
shutdown of the Surry Power Station. The fuel currently stored would
have to be removed. The electrical generation capacity lost would
likely negatively impact the local economy and infrastructure of the
area. For these reasons, the ``no action'' alternative is not
considered a practical alternative.
As discussed in the EA, the Commission has concluded that there are
no significant environmental impacts associated with renewing the
license of the Surry ISFSI, and other alternatives were not pursued
because of significantly higher costs, additional occupational
exposures, and the unavailability of offsite storage options.
Agencies and Persons Contacted: Officials from the Virginia
Department of Emergency Services, the Virginia Department of Historic
Resources, the U.S. Fish and Wildlife Service, and the Virginia
Department of Environmental Quality, were contacted in preparing the
staff's environmental assessment. The conclusions by all agencies
consulted were consistent with the staff's conclusions.
II. Finding of No Significant Impact
The staff has reviewed the environmental impacts of renewing the
Surry ISFSI license relative to the requirements set forth in 10 CFR
Part 51, and has prepared an EA. Based on the EA, the staff concludes
that there are no significant radiological or non-radiological impacts
associated with the proposed action and that issuance of renewal of the
license for the interim storage of spent nuclear fuel at the Surry
ISFSI will have no significant impact on the quality of the human
environment. Therefore, pursuant to 10 CFR 51.31 and 51.32, a finding
of no significant impact is appropriate and an environmental impact
statement need not be prepared for the renewal of the materials license
for the Surry ISFSI.
