Department of the Navy
Record of Decision for a Dry Storage Container System for the
Management of Naval Spent Nuclear Fuel
SUMMARY: Pursuant to section 102(2) of the National Environmental
Policy Act (NEPA) of 1969; the Council on Environmental Quality
regulations implementing NEPA procedures, 40 CFR Parts 1500-1508; and
Chief of Naval Operations Environmental and Natural Resources Program
Manual, OPNAV Instruction 5090.1B; the Department of the Navy announces
its decision to implement the preferred alternative (dual-purpose
canisters) identified in the final Environmental Impact Statement for a
Container System for the Management of Naval Spent Nuclear Fuel (EIS)
dated November 1996. The Department of Energy (DOE), which participated
as a cooperating agency, formally adopted the final EIS on October 9,
1996 (designated as DOE/EIS-0251) (61 FR 59435) and has concurred in
this Record of Decision. The DOE was a cooperating agency because the
DOE, under the Nuclear Waste Policy Act, is responsible for the
ultimate disposition of all spent nuclear fuel, including civilian and
military. The DOE is also responsible for the facilities at the Idaho
National Engineering Laboratory (INEL) where naval spent nuclear fuel
is currently stored. The Navy will utilize a dual-purpose canister
system for the management of naval spent nuclear fuel and the
management of naval special case low-level radioactive waste. A dual-
purpose canister system will be used for the loading, dry storage,
transport, and possible disposal of naval spent nuclear fuel following
examination at the INEL. This Record of Decision neither decides nor
presumes that naval special case waste will be shipped to a geologic
repository or a centralized interim storage site as naval spent nuclear
fuel.

Introduction
More than 40% of the Navy's principal combatants are nuclear
powered. Since 1955, U.S. nuclear powered warships have steamed safely
more than one hundred million miles and accumulated over 4,700 reactor
years of safe operation. Continued operation of the Navy's nuclear
powered warships remains a vital element of the Navy's ability to
fulfill its national security mission in support of our nation's
defense.
The Navy creates spent nuclear fuel through the operation of its
nuclear powered warships and training reactors. When a warship is
refueled for continued service or is defueled because it is being
inactivated, its spent nuclear fuel is removed at a shipyard.
Similarly, naval spent nuclear fuel is removed from afloat and land-
based training reactors when they are refueled or deactivated. In all
cases, the naval spent nuclear fuel is transported to the INEL in
southeastern Idaho where it is examined at the Expended Core Facility
(ECF) located at the Naval Reactors Facility (NRF). This examination is
essential to verify the performance of current naval nuclear fuel and
to support the design of naval fuel with longer lifetimes. After
examination, the naval spent nuclear fuel is transferred to the Idaho
Chemical Processing Plant (ICPP) for storage in water pools pending
final disposition. Currently, there are approximately 13 metric tons of
heavy metal of naval spent nuclear fuel at the INEL. A total of
approximately 65 metric tons of naval spent nuclear fuel will exist by
the year 2035.
The Navy is committed to ensuring that post-examination naval spent
nuclear fuel is managed in a fashion which (1) facilitates ultimate
safe shipment to a permanent geologic repository or centralized interim
storage site outside the State of Idaho;
(2) protects the Idaho environment while being temporarily stored
at the INEL;
(3) is consistent with the DOE Programmatic Spent Nuclear Fuel
Management and INEL Environmental Restoration and Waste Management
Programs Final Environmental Impact Statement (April 1995); and
(4) complies with the court ordered agreement among the State of
Idaho, the DOE, and the Navy, which is discussed in this Record of
Decision under Legal and Regulatory Considerations.
Until a geologic repository or centralized interim storage site
outside the State of Idaho (discussed in Section 2.8.2 of the final
EIS) is available, the Navy is committed to a number of actions to
ensure uninterrupted operation of the Navy's nuclear powered fleet.
These include transfer of all naval spent nuclear fuel at the INEL out
of wet storage facilities into dry storage, completion of a Dry Cell
expansion project at the ECF, completion of Hot Cell facility upgrades
at the ECF, construction of an ECF dry storage container loading
station, and performance of certain environmental restoration work at
the NRF. The high integrity and rugged nature of naval spent nuclear
fuel make it exceptionally well suited for safe transport, storage, and
ultimate disposal after service. The Navy must make a decision on the
type of dry storage container system now in order to support planning
required to meet its commitment as discussed in this Record of Decision
under Legal and Regulatory Considerations for dry storing naval spent
nuclear fuel and ultimately shipping it out of the State of Idaho.
Alternatives Considered
The Navy considered six alternative dry storage container systems
for the loading, storage, transport, and possible disposal of post-
examination naval spent nuclear fuel and the management of special case
waste. The alternatives may use either of the existing dry storage
containers or of dry storage containers that could be produced by
manufacturers of such equipment. Because of differences in
configurations of naval spent nuclear fuel assemblies, all of the
alternatives require containers to have internal baskets designed for
specific naval spent nuclear fuel types.
Two time frames were used for analyses. For complete system
operations, 1996-2035, a time period of 40 years is used. For analyses
concerning transportation to a spent nuclear fuel repository and
handling of post-examination naval spent nuclear fuel at the INEL, the
period 2010 to 2035 (25 years) was used because a repository would be
expected to begin accepting spent nuclear fuel before 2010. The actual
date that a repository would begin accepting spent nuclear fuel would
have minimal impact on the results presented in the final EIS and would
not change the number of shipments to be made.
There is also the possibility that a centralized storage site may
be designated for interim storage of civilian
[[Page 1096]]
spent nuclear fuel until a repository is available. If such a
centralized interim storage site were opened and if naval spent nuclear
fuel were allowed by law to be stored there, transportation of naval
spent nuclear fuel might begin before 2010. A range of transportation
routes was analyzed in the EIS. As such, the transportation analyses
are suitable for comparison of the impacts associated with
transportation to a centralized interim storage site among
alternatives.
A brief description of the six alternatives follows:
(1) No-Action Alterative--Use of existing technology to handle,
store, and subsequently transport naval spent nuclear fuel to a
geologic repository or a centralized interim storage site using the
Navy M-140 transportation cask. Prior to shipment to a repository or
centralized interim storage site, naval spent nuclear fuel would be
managed at the INEL in water pools or commercially available dry
storage containers, then loaded into M-140 transportation casks. At a
repository, the naval spent nuclear fuel would be unloaded from the M-
140 transportation casks and placed in a geologic repository's surface
facilities for loading into disposal containers. Following unloading,
the M-140 transportation casks would be returned to the INEL for reuse.
Because existing M-140 transportation casks are needed to maintain
scheduled fleet refuelings and defuelings, approximately 24 additional
M-140 transportation casks would have to be manufactured to handle the
shipment of about 425 cask loads of naval spent nuclear fuel to a
repository between 2010 and 2035. Two hundred and twenty-five dry
storage containers would be required for use at the INEL, and 300
disposal containers would be required under this alternative. For the
management of special case waste, up to 30 additional dry storage
containers, four additional M-140 transportation casks, and 60
additional disposal containers would be needed.
(2) Current Technology/Supplemented by High Capacity Rail
Alternative--This alternative uses the same storage methods and M-140
transportation casks described in the no-action alternative, but with
redesigned internal structures for the M-140 cask to accommodate a
larger amount of naval spent nuclear fuel per cask, thus reducing the
total number of shipments required. For the purpose of analysis, the
EIS assumes that approximately 24 additional M-140 transportation casks
would be needed in order to expedite shipment of approximately 325
containers of naval spent nuclear fuel by rail to a repository or
centralized interim storage site. One hundred and fifty dry storage
containers would be required for use at the INEL, and 300 disposal
containers would be required under this alternative. For the management
of special case waste, up to 26 additional dry storage containers, four
additional M-140 transportation casks, and 60 additional disposal
containers would be needed.
(3) Transportable Storage Cask Alternative--This alternative uses
an existing, commercially available transportable storage cask for
storage at the INEL as well as for transportation to a repository or
centralized interim storage site. At a repository, individual
assemblies of naval spent nuclear fuel would be unloaded from the casks
and placed in surface facilities for loading into disposal containers.
The unloaded transportable storage casks would be returned to the INEL
for further storage and transport. Approximately 325 shipments of the
reusable transportable storage cask (150 casks required) would be
necessary for the shipment of all naval spent nuclear fuel and 300
containers would be required for disposal. For the management of
special case waste, up to 21 additional storage casks and 60 additional
disposal containers would be needed.
(4) Dual-Purpose Canister Alternative--This alternative uses an
existing, commercially available canister and overpack system for
storage at the INEL and shipment of naval spent nuclear fuel to a
geologic repository or centralized interim storage site. At a
repository, the naval spent nuclear fuel would be unloaded from the
canisters and placed in surface facilities for loading into disposal
containers. Approximately 300 canisters would be required for dry
storage and shipment of naval spent nuclear fuel by rail to a
repository or centralized interim storage site. In addition, 150 dry
storage overpacks for use at the INEL, 15 transportation overpacks, and
300 disposal containers would be required. For the management of
special case waste, up to 45 additional canisters, 23 additional
storage overpacks, three additional transportation overpacks, and 60
additional disposal containers would be needed.
(5) Multi-Purpose Canister Alternative--This alternative uses about
300 large (125-ton) multi-purpose canisters for storage,
transportation, and disposal of naval spent nuclear fuel, without
repackaging or further handling of individual spent nuclear fuel
assemblies. In addition to the sealed metal canisters, specialized
casks or overpacks would be required for different stages of the
process, including 150 dry storage overpacks for use at the INEL, 15
transportation overpacks for transporting naval spent nuclear fuel to a
geologic repository or centralized interim storage site, and 300
disposal overpacks for disposal in a repository. For the management of
special case waste, up to 60 additional canisters, 30 additional
storage overpacks, three additional transportation overpacks, and 60
additional disposal overpacks would be needed.
(6) Small Multi-Purpose Canister Alternative--This alternative uses
about 500 smaller (75 ton) multi-purpose canisters, rather than large
multi-purpose canisters. The small multi-purpose canisters would be
similar in design, operations, and function to the large multi-purpose
canisters, but would offer a lower weight and size alternative for
transportation and handling at a geologic repository or centralized
interim storage site. Two hundred and twenty-five dry storage overpacks
for use at the INEL, 25 transportation overpacks for transporting naval
spent nuclear fuel to a geologic repository or centralized interim
storage site, and 500 disposal overpacks for disposal in a repository
would be required. For the management of special case waste, up to 85
additional canisters, 39 additional storage overpacks, five additional
transportation overpacks, and 85 additional disposal overpacks would be
needed.
Decisions
The Navy announces its decision to use a dual-purpose canister
system for the management of post-examination naval spent nuclear fuel
and special case low-level radioactive waste. The primary benefits of a
dual-purpose canister system are efficiencies in container
manufacturing and fuel reloading operations and potential further
reduction in radiation exposure. A dual-purpose canister system will
allow the safe storage and shipment of naval spent nuclear fuel for
ultimate disposition. The system might also be found to be acceptable
for disposal purposes once the disposal requirements for a geologic
repository have been formulated and finalized, making it functionally
equivalent to a multi-purpose canister system.
The Navy evaluated each of the alternatives to a set of criteria in
order to select a preferred alternative. The results of that evaluation
are summarized briefly below.
There was no obvious preference for any dry storage container
system based on public comments. Further, all of the alternative dry
storage container
[[Page 1097]]
systems technically support the storage, shipment, and disposal of
naval spent nuclear fuel.
The Department of the Navy's analysis of the environmental and
public health impacts from the following would be small and would
differ little among alternatives: the manufacture of any of the dry
storage container systems; the operations of handling, storage,
transportation and unloading at a repository; and the construction of
facilities. All alternatives are considered comparable and
indistinguishable under this criterion, thus, there is no
environmentally preferred alternative.
Cost comparisons were based on procurement costs for equipment, as
well as handling, storage, transportation and container disposal costs.
Under this criterion, the dual-purpose canister system has a medium
comparative cost. The multi-purpose canister has the lowest comparative
cost, in part because the fuel assemblies would only be handled one
time, but since no multi-purpose canisters currently exist the cost
comparison is somewhat conjectural. If the dual-purpose canister
alternative meets the repository design criteria for disposal packages
when those criteria are established, fuel assemblies would be handled
once instead of twice, and the cost would decrease such that it would
be comparable with the multi-purpose canister. There is a high
probability that a dual-purpose canister system for naval spent nuclear
fuel can be produced successfully and economically because it is
similar to currently available systems for civilian spent fuel.
To evaluate operational efficiency, the Navy evaluated the
processes which must be performed for any of the alternatives,
including: loading fuel into dry storage containers, unloading fuel
from dry storage containers for shipment, off-site transport, and
loading or reloading fuel at a geologic repository surface facility for
ultimate disposal. Each of these general operations may be performed
once, multiple times, or not at all, depending on the system
implemented. Each of the alternatives can be categorized as either a
cask or a canister system based on whether the naval spent nuclear fuel
would be transferred from storage for shipment as collections of
individual fuel assemblies (cask) or as a unit inside a sealed package
(canister).
It was concluded from the process evaluation that multi-purpose
canister systems would be the most efficient systems when considering
the handling of fuel. Individual fuel assemblies would not have to be
unloaded from the canisters once they had been loaded for the multi-
purpose canister alternatives. The individual fuel assemblies would be
handled only one time: during the initial loading of the canister. The
most inefficient systems from this standpoint are the No-Action and the
Current Technology/Rail Alternatives because individual fuel assemblies
must be handled three times, once for each packaging operation.
For the dual-purpose canister system, the individual fuel
assemblies would be loaded into a canister prior to storage. The
canister would not need to be reopened prior to packaging the canister
for transportation. It is possible that at a geologic repository the
individual fuel assemblies may need to be handled in the process of
packing disposal containers. However, if the canisters meet repository
disposal criteria when these criteria are established, the dual-purpose
canister system would be functionally equivalent to a multi-purpose
canister system in that the individual fuel assemblies would be handled
only once. Although handling fuel is routinely accomplished safely
without impact on human health or the environment, doing it multiple
times is inefficient, and incurs additional occupational radiation
exposure and some risk.
With respect to regulatory and disposal criteria impacts, the only
anticipated changes that may affect the selected alternative are in the
area of repository disposal regulations. The Environmental Protection
Agency (EPA) is expected to issue revised draft standards (40 CFR part
197) for a geologic repository in 1997. The Nuclear Regulatory
Commission (NRC) plans to issue changes to its repository disposal
regulations (10 CFR part 60) to establish design criteria within one
year of the issue of the EPA standards.
Based on the uncertainties and far term nature of the disposal
regulations, there are no discernible advantages or disadvantages
associated with any of the alternatives based on potential impact of
disposal regulations. No changes affecting this evaluation in the
storage and transportation regulations are anticipated and all of the
alternatives would meet the current regulations.
The Navy anticipates that final waste acceptance criteria for a
geologic repository will not be established for at least five years. As
a result there is some uncertainty in implementing a multi-purpose
canister system at this time. The Navy cannot wait five years for the
establishment of waste criteria plus any additional time required to
develop a multi-purpose canister based on such criteria in order to
meet its commitment as discussed in this Record of Decision under Legal
and Regulatory Considerations. If a multi-purpose canister is not
compatible with geologic repository criteria, the fuel canisters may
need to be opened and the individual fuel assemblies handled and placed
into acceptable disposal containers. In this event the multi-purpose
canister system would essentially become a dual-purpose canister
system.
The Navy also considered the direction of industry and
standardization in selecting an alternative. In implementing a dry
storage container system for the management of naval spent nuclear
fuel, there is an advantage in utilizing a system compatible with the
systems in use or planned for use by operators of reactors which
commercially generate electricity. All spent nuclear fuel, commercial
and naval, is destined for the same geologic repository or could be
destined for the same centralized interim storage site if such a site
were opened and naval spent nuclear fuel were allowed by law to be
stored there. Naval spent nuclear fuel containers will represent only
about one to four percent of the total number of containers that would
be shipped to a repository or centralized interim storage facility.
Therefore, to the extent that the most widely used systems for
commercial spent nuclear fuel drive any repository design or acceptance
criteria, it is considered prudent to utilize a system which is similar
to the systems being used or planned for use by commercial electric
utilities. Other advantages to using the same system or one similar to
that which the commercial utilities have recently licensed through the
NRC include prior completion of extensive technical reviews, prior
completion of peer and public review, and some proven applications
which may be in operation.
The majority of the new spent nuclear fuel storage systems being
designed or in review by the NRC are dual-purpose systems with
different overpacks for storage and transport. The 125-ton multi-
purpose canister, the 75-ton multi-purpose canister, the transportable
storage cask and the dual-purpose canister system were all found to
reflect current industry direction. The No-Action and the Current
Technology/Rail Alternatives do not.
Finally, the Navy looked at technical uncertainties and risks.
There are no substantial technical uncertainties associated with the
loading of naval nuclear spent fuel into dry storage containers, the
storage of the containers at the INEL, or the transportation off-site
[[Page 1098]]
to a geologic repository. All of the alternatives assume the use of dry
storage containers which will meet the storage requirements of 10 CFR
part 72 and the transportation requirements of 10 CFR part 71. Several
licensed systems are currently in use and other new systems are in the
review cycle for NRC approval for use.
As discussed in this Record of Decision under Legal and Regulatory
Considerations, the Navy must select a dry storage container system now
to support completion of its commitments for dry storing naval spent
nuclear fuel. Thus, the Navy cannot wait a minimum of five years
anticipated for the establishment of waste criteria plus any additional
time required to develop a multi-purpose canister based on such
criteria. Dual-purpose canisters represent the best system given the
need to make a decision now and their favorable comparison to the other
alternatives considering cost, operational efficiency, industry trends,
regulatory acceptance, and the other criteria discussed above.
Mitigation
The strictly controlled conduct of operations associated with the
DOE and Naval Nuclear Propulsion Program spent fuel management
activities are mitigation measures integral to the selected
alternative. The DOE and the Naval Nuclear Propulsion Program have
directives and regulations for conduct of spent nuclear fuel management
operations. All government spent fuel shipments must comply with the
DOE and Department of Transportation regulations. The DOE and the Navy
have adopted stringent controls for minimizing occupational and public
radiation exposure. The policy of these programs is to reduce radiation
exposures to as low as reasonably achievable (ALARA). Singly and
collectively, these measures avoid, reduce, or eliminate any
potentially adverse environmental impacts from spent nuclear fuel
management activities, including those associated with
containerization. The Navy and the DOE have not identified a need for
additional mitigation measures.
Legal and Regulatory Considerations
The Record of Decision for the DOE Programmatic Spent Nuclear Fuel
Management and Idaho National Engineering Laboratory Environmental
Restoration and Waste Management Programs Final Environmental Impact
Statement was issued on June 1, 1995 (60 FR 28680). On October 17,
1995, the federal District Court entered a Consent Order that resolved
all issues related to the EIS raised by the State of Idaho and the
Governor of Idaho. The Consent Order incorporated as requirements all
of the terms and conditions of the parties' Settlement Agreement,
including a reduction in the number of spent nuclear fuel shipments
coming to the State of Idaho.
All proposed actions by the Navy will be in full compliance with
the requirements of the Consent Order/settlement agreement among the
State of Idaho, the U.S. Navy, and the DOE. The settlement agreement
included an obligation of the Naval Nuclear Propulsion Program to fund
a dry storage container loading station at ECF, expending no less than
$20 million on that project by October 2000. This Record of Decision is
consistent with that obligation. The settlement agreement also
obligates the DOE to commence moving spent nuclear fuel currently in
water pool storage into dry storage by July 1, 2003.
In addition to the Consent Order, Chapter 8 of the final EIS
identifies the major applicable laws and regulations which the
Department of the Navy is mandated to comply with in the fabrication
and utilization of a dry storage container system for the management of
naval spent nuclear fuel.
Public Involvement
On October 24, 1994, the DOE published a Notice of Intent in the
Federal Register (59 FR 53442) to prepare an EIS for a multi-purpose
canister system for the management of civilian spent nuclear fuel. As
part of the public scoping process, the scope of the EIS for the multi-
purpose canister system was broadened to include naval spent nuclear
fuel. This determination was included in the Implementation Plan whose
availability was announced in the Federal Register on August 30, 1995
(60 FR 45147). However, the DOE halted its proposal to fabricate and
deploy a multi-purpose canister based system and ceased preparation of
that EIS.
On December 7, 1995 the Department of the Navy published a notice
in the Federal Register (60 FR 62828) assuming the lead responsibility
for an Environmental Impact Statement evaluating dry storage container
systems for the management of naval spent nuclear fuel. The Department
of the Navy assumed the lead responsibility from the DOE and narrowed
the focus of the EIS to include only naval spent nuclear fuel. Despite
the narrowing of the focus to only naval spent nuclear fuel and the
change in lead agency, the range of dry storage container alternatives
being considered did not change. Thus the EIS did not require another
scoping process. The DOE became a cooperating agency rather than the
lead agency in the preparation of that EIS.
On May 1, 1996, the Navy distributed the Draft EIS. The Notice of
Availability of the Draft EIS was announced in the Federal Register on
May 14, 1996 along with the locations and dates of public hearings (61
FR 24293). The Draft EIS was widely distributed to public officials,
tribal officials, and state agencies in the areas of potential
interest, as well as to individuals requesting the document. The public
comment period for the EIS was originally scheduled to be 45 days, but
a 15-day extension was granted based on a request from the State of
Nevada. During the public comment period, six public hearings were held
and both written and oral comments were received. Oral and written
comments were received from 51 parties, representing: federal, state,
and local agencies and officials; special interest groups; and
individuals.
Although no substantive changes to the Draft EIS were needed as a
result of public comments, several clarifications and editorial changes
were made in response to comments. For example, the Final EIS was
modified to clearly state that the effect of a terrorist attack or an
act of sabotage is expected to be conservatively bounded by the
limiting accidents already discussed. The discussion of transportation
routes used in the analysis was expanded to explain their application.
In addition, the EIS was modified to enhance the reader's ability to
use the results of analyses to evaluate the possibility that any of the
alternatives might have a disproportionately high and adverse impact on
minority or low-income populations.
A new Chapter 11 was added to the Final Environmental Impact
Statement in which each comment was reprinted in its entirety, followed
immediately by individual responses to each of the major points. The
EPA formally announced the availability of the final EIS on November
22, 1996 (61 FR 59435). The Navy also announced the availability of the
final EIS on November 22, 1996 (61 FR 59423).
Approval
This Record of Decision constitutes the Department of the Navy's
final action with regard to selection of a dry storage container system
for the management of post-examination naval spent nuclear fuel and
naval special case low-level radioactive waste. This Record of Decision
does not constitute
[[Page 1099]]
final action for location(s) for dry loading naval spent nuclear fuel
which is currently stored at the ICPP or which will be stored at ICPP
prior to establishment of a dry storage facility, or for location(s)
for temporary dry storage of naval spent nuclear fuel at the INEL.
Those actions will be the subject of an upcoming Record of Decision.
Issued in Washington, D.C., this 26th day of December 1996.
