NUCLEAR REGULATORY COMMISSION
[Docket No. 50-333]
Power Authority of the State of New York; James A. Fitzpatrick
Nuclear Power Plant; Environmental Assessment and Finding of No
Significant Impact
The U.S. Nuclear Regulatory Commission (the Commission) is
considering issuance of an amendment to Facility Operating License No.
DPR-59, issued to the Power Authority of the State of New York (PASNY)
(the licensee, also known as the New York Power Authority), for
operation of the James A. FitzPatrick Nuclear Power Plant, located in
Oswego County, New York.
Environmental Assessment
Identification of the Proposed Action
The proposed action would modify the spent fuel pool (SFP) by
installation of an additional 7 new high density storage rack modules
for fuel storage in the SFP. The additional rack modules will increase
the FitzPatrick SFP capacity from 2797 to 3239 fuel assemblies.
The proposed action is in accordance with the licensee's
application for amendment dated October 14, 1997, as supplemented on
July 23, 1998, December 3, 1998, February 25, 1999, and September 29,
1999.
The Need for the Proposed Action
The proposed action is needed to provide for storage of spent fuel
until the licensee installs and obtains a license for an interim spent
fuel storage installation (IFSFI). The underlying purpose of the
expansion is to provide interim additional storage capacity for spent
fuel to allow for continued operation until additional methods of
storing spent fuel have been established.
Environmental Impacts of the Proposed Action
The factors considered in this determination are discussed below.
Radioactive Waste Treatment
FitzPatrick uses waste treatment systems designed to collect and
process gaseous, liquid, and solid waste that might contain radioactive
material. These radioactive waste treatment systems are evaluated in
the Final Environmental Statement (FES) dated March 1973. The proposed
SFP expansion will not involve any change in the waste treatment
systems described in the FES.
Radioactive Material Released to the Atmosphere
The storage of additional spent fuel assemblies in the SFP is not
expected to affect the releases of radioactive gases from the SFP.
Gaseous fission products such as Krypton-85 and Iodine-131 are produced
by the fuel in the core during reactor operation. A small percentage of
these fission gases may be released to the reactor coolant from fuel
assemblies which may develop leaks during reactor operation. During
refueling operations, some of these fission products may enter the SFP
and subsequently be released into the air. However, as the frequency of
refuelings will not be increased by the proposed action, there will be
no increase in the amount of radioactive material released to the
atmosphere during these operations.
Experience has demonstrated that during the period between
refueling outages there is no longer a significant release of fission
products from stored fuel. The storage of additional fuel assemblies in
the SFP will not increase the SFP bulk water temperature beyond the
existing design temperature. Therefore, radioactive material airborne
release rates due to evaporation from the SFP are not expected to
increase.
Solid Radioactive Wastes
Spent resins are generated by the processing of SFP water through
the SFP purification system. These spent resins are disposed of as
solid radioactive waste. The frequency of resin changeout may increase
slightly during the installation of the new racks due to the
possibility of resuspension of particulate matter in the SFP (due to
turbulence caused by the SFP rack installations). The licensee will use
a Tri-Nuke underwater filtration unit to
[[Page 61168]]
clean the floor of the SFP during SFP rack installation. Vacuuming of
the SFP floor will remove any extraneous debris and crud and ensure
visual clarity in the SFP (to facilitate diving operations, if needed,
and installation of the SFP racks). Debris and crud will be filtered
and collected in the Tri-Nuke filters and stored underwater. Depending
on the waste characterization of these filters, the licensee will
dispose of them utilizing shielded canisters and high integrity
containers which will then be stored onsite or shipped for burial
accordingly. The staff does not expect that the additional fuel storage
made possible by the increased SFP storage capacity will result in a
significant change in the generation of solid radwaste.
Liquid Radioactive Wastes
The release of radioactive liquids will not be affected directly as
a result of the modifications. The SFP ion exchanger resins remove
soluble radioactive materials from the SFP water. When the resins are
changed out, the small amount of resin sluice water which is released
is processed by the radwaste system. As stated above, the frequency of
resin changeout may increase slightly during the installation of the
new racks. However, the amount of radioactive liquid released to the
environment as a result of the proposed SFP expansion is expected to be
negligible.
Radiological Impact Assessment
Radiation Protection personnel will constantly monitor the doses to
the workers during the SFP expansion operation. The total occupational
dose to plant workers as a result of the SFP expansion operation is
estimated to be between 3 and 4 person-rem. Since the proposed action
does not involve the removal of any spent fuel racks, the licensee does
not plan on using divers for this project. However, if it becomes
necessary to utilize divers to remove any interferences which may
impede the installation of the new spent fuel racks, the licensee will
equip each diver with radiation detectors with remote, above surface,
readouts which will be continuously monitored by Radiation Protection
personnel. This dose estimate is comparable to doses for similar SFP
modifications performed at other plants. The proposed SFP rack
installation will follow detailed procedures prepared with full
consideration of as low as is reasonably achievable (ALARA) principles.
On the basis of our review of the FitzPatrick proposal, the staff
concludes that the FitzPatrick SFP rack installation can be performed
in a manner that will ensure that doses to workers will be maintained
ALARA. The estimated dose of 3 to 4 person-rem to perform the proposed
SFP rack installation is a small fraction of the annual collective dose
accrued at FitzPatrick.
Accident Considerations
In its application, the licensee evaluated the possible
consequences of a fuel handling accident to determine the thyroid and
whole-body doses at the Exclusion Area Boundary (EAB), Low Population
Zone (LPZ), and Control Room.
The proposed SFP rack installation at the FitzPatrick Nuclear Power
Plant will not affect any of the assumptions or inputs used in
evaluating the dose consequences of a fuel handling accident and
therefore will not result in an increase in the doses from a postulated
fuel handling accident.
The proposed action will not increase the probability or
consequences of accidents, no changes are being made in the types of
any effluents that may be released offsite, 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 involve 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 Commission concludes that there are no significant
environmental impacts associated with the proposed action.
Alternatives to the Proposed Action
Shipping Fuel to a Permanent Federal Fuel Storage/Disposal Facility
Shipment of spent fuel to the permanent repository or a centralized
high-level radioactive waste storage facility is an alternative to
increasing onsite spent fuel storage capacity. However, the U.S.
Department of Energy (DOE) is not expected to open the permanent
repository until 2010 and is currently prohibited from selecting a site
for centralized storage until after a determination is made on
permanent repository site suitability. Congress, with the urging of
some affected utilities and States, has recently taken up proposed
changes to the Federal program that would integrate storage and
disposal at one site and require DOE to construct an interim storage
facility. No decision has yet been made on centralized federal storage
that would provide a basis for evaluating it as a viable alternative to
the Power Authority's proposed action.
Shipping Fuel to a Reprocessing Facility
Reprocessing of spent fuel from the FitzPatrick plant is not a
viable alternative since there are no operating commercial reprocessing
facilities in the United States. Spent fuel would have to be shipped to
an overseas facility for reprocessing. This approach has never been
used and it would require approval by the U.S. Department of State as
well as other entities. Additionally, the cost of spent fuel
reprocessing is not offset by the salvage value of the residual uranium
and reprocessing represents an added cost. Therefore, this alternative
is considered unacceptable.
Shipping Fuel to Another Utility or Site or to Indian Point 3 (IP3) for
Storage
Shipment of irradiated fuel from FitzPatrick for storage at the IP3
fuel pool would provide short-term relief from the storage problem at
FitzPatrick. However, this transfer of fuel between units would create
no additional storage locations for irradiated fuel, nor would it
eliminate the need to develop additional spent fuel storage capability
at FitzPatrick in the future. As a result, any fuel transfer would
accelerate the loss of fuel pool storage at the IP3 and give no benefit
to either facility.
Currently, the IP3 site has installed fuel pool storage capacity
sufficient to handle site requirements for irradiated fuel storage,
while maintaining full core discharge capability until approximately
the year 2009. The design of the IP3 fuel pool storage racks has been
optimized for storage of pressurized-water reactor fuel with a
different physical and nuclear design than the boiling-water reactor
fuel used at FitzPatrick. Thus, storage of FitzPatrick fuel at IP3
would both limit storage of future discharged IP3 fuel and represent a
less then optimal use of the existing IP3 storage capability.
PASNY knows of no other utility that is prepared to accept
shipments of irradiated fuel from FitzPatrick for long-term storage at
its site.
For these reasons, and considering the increased fuel handling and
additional occupational radiation exposure incurred during the shipment
of irradiated fuel, the alternative of shipping FitzPatrick fuel to IP3
or other site for storage is not an acceptable alternative to the
proposed action.
[[Page 61169]]
Alternatives Creating Additional Storage Capacity
A variety of alternatives to increase the storage capacity of the
FitzPatrick SFP were considered. Fuel rod consolidation was considered
as a potential alternative and was eliminated because of the limited
industry experience in disassembling irradiated fuel and because of the
potential for fission product release due to rod breakage during
disassembly. Additionally, because DOE considers consolidated fuel to
be a non-standard waste form, the licensee could be concerned that the
presence of fuel in this form would cause DOE to delay its acceptance
of waste from FitzPatrick.
The early implementation of dry cask storage for irradiated fuel at
FitzPatrick was also considered. Dry cask storage involves transferring
irradiated fuel, after several years of storage in the FitzPatrick SFP,
to high capacity casks with passive heat dissipation features. After
loading, these casks would be placed on a concrete pad at an outdoor
location on the FitzPatrick site. Although dry cask storage is planned
by the licensee as a long-term storage option for FitzPatrick, the
early implementation of this alternative was rejected by the licensee
because the 442 storage locations provide needed irradiated fuel
storage with less environmental impact and at lower cost.
As a result, the licensee concluded that none of the alternative
technologies that could create additional spent fuel storage capacity
at FitzPatrick could do so with less environmental impact than the
impacts associated with the chosen option.
Reduction of Spent Fuel Generation
To minimize the quantities of irradiated fuel generated during full
power operation at FitzPatrick, the licensee has developed efficient
fuel loading patterns that seek to maximize the utilization of each
assembly consistent with limits on the integrated fuel rod exposure.
Batch discharge burnups for FitzPatrick fuel currently exceed 40 GWD/MT
with peak assembly burnups reaching 46 GWD/MT by the time of discharge.
The licensee expects batch average discharge exposure to exceed 43 GWD/
MT after the current cycle and to increase to 45 GWD/MT thereafter.
FitzPatrick depletes fuel assemblies to these burnups with minimal
cladding perforations so that the fission product inventory present in
the SFP water remains low. The high values of batch average and peak
assembly discharge burnup ensure that the electricity generated by
FitzPatrick yields the minimum possible amount of spent fuel.
The fuel assembly design used at FitzPatrick is not compatible with
the IP3 core. As a result, partially irradiated fuel from other PASNY
nuclear units cannot be used at FitzPatrick (or vice versa) to reduce
the rate of spent fuel discharge.
Operation of FitzPatrick at a reduced power level for long periods
of time would extend the existing SFP storage capacity. However, to
compensate for the reduced generation by FitzPatrick another power
generation facility would be required to increase its power output,
possibly resulting in an increase in airborne pollution and greenhouse
gas emissions. The adverse environmental impact of increased airborne
pollution and greenhouse gas omissions resulting from a long-term
derate of FitzPatrick generating capacity is significantly greater than
the environmental impact associated with increasing the storage
capacity of the existing FitzPatrick SPF.
The No-Action Alternative
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 significant change in
current environmental impacts. The environmental impacts of the
proposed action and the alternative action are similar.
Alternative Use of Resources
This action does not involve the use of any resources not
previously considered in the Final Environmental Statement for
FitzPatrick.
Agencies and Persons Consulted
In accordance with its stated policy, on May 24, 1999, the NRC
staff consulted with the New York State official, Mr. Jack Spath, of
the New York State Research and Development Authority, 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 Commission
concludes that the proposed action will not have a significant effect
on the quality of the human environment. Accordingly, the Commission
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 October 14, 1997, as supplemented by letters
