Fissile Material: As of February
6, 1996, there were 2.0 metric tons of plutonium, 575 kg of plutonium waste,
and approximately 24.4 metric tons of U-235 in the form of metal, irradiated
fuel, encapsulated fresh fuel, oxide, and other forms.
The Savannah River Site (SRS) consists of 198,344 acres (310 square
miles) located approximately 25 miles southeast of Augusta, Georgia, in the
state of South Carolina. The site is within the Atlantic coastal plain,
bordered by the Savannah River. The topography is gently sloping to
moderately steep.
SRS's primary mission since its
inception until the early 1990s was production and separation of plutonium
and tritium for use in national defense programs. The current SRS mission
involves waste management and vitrification, special nuclear material (SNM)
storage, research and development, and technology transfer. SRS also
recycles tritium from the weapons stockpile. Recycling is accomplished at
the tritium facilities (232-H, 233-H, and 234-H). High level waste is being
stabilized through vitrification and disposal of the low activity fraction
of waste as saltstone. Other secondary missions involve disposition of
nuclear materials and facilities, including five production reactors (all of
which are shut down), three chemical separation plants, three tritium
facilities, 51 high level waste underground storage tanks, and a high level
waste processing facility.
Contractor activities at SRS are
managed by the Department of Energy (DOE) Savannah River Operations Office
(SR). SR has approximately 563 personnel as of October 1996. Westinghouse
Savannah River Company--who teamed with Bechtel Savannah River Company,
Inc.; B&W Savannah River Company; and BNFL Savannah River Corporation--was
recently awarded the contract for integrated team management of the site.
There are also a significant number of subcontractors that support this
team. Approximately 13,900 personnel are assigned to this contract as of
September 30, 1996. (See Finance Issues, below.) Other
contractors/interagency agreements at SRS include Wackenhut Services, Inc.,
which is responsible for site security; the U.S. Forest Service, which is
responsible for forest management; the University of Georgia, which manages
the Savannah River Ecology Laboratory; and the U.S. Army Corps of Engineers,
which assists with oversight of design and construction activities.
The Savannah River
Integrated Team Management Contract was awarded to the Westinghouse Savannah
River Company (WSRC) effective October 1, 1996. The five year, $6 billion
contract is a performance-based contract that provides payment of fees to
contractors only if they achieve specific, defined results.
The Savannah River Integrated Team Management Contract provides a
framework to accelerate the implementation of contract reform initiatives,
to increase productivity and cost-effectiveness, and to improve contractor
performance and accountability. The contract includes the following
results-oriented performance objectives:
- Maximizing the conversion of high level liquid waste into solid
(glass) form through the Defense Waste Processing Facility to reduce life
cycle costs, and attain production rates of greater than 150 canisters in
fiscal year 1997 before any incentive fee is paid.
- Reducing costs for maintenance and monitoring of old high level waste
tanks by closing three tanks in fiscal year 1997.
- Completing Defense Nuclear Facilities Safety Board (DNFSB)
Recommendation 94-1 nuclear material stabilization commitments by the end
of fiscal year 2001 on an accelerated schedule. Stabilization of existing
nuclear materials at the site will reduce proliferation risk, reduce
potential for inadvertent nuclear criticality, and substantially reduce
surveillance and maintenance costs.
- Reducing costs of funded environmental restoration (ER) activities and
using these cost savings to accelerate ER activities, which expedite
completion of these efforts, enable unfunded environmental restoration
projects to be initiated, and produce faster and more cost-effective
cleanup of the site.
- Consolidating tritium operations into fewer facilities while meeting
all production requirements to permit earlier cleanup of unneeded
facilities, thereby reducing costs.
Storage of High-Level Radioactive Wastes
SRS tank farms store approximately 35 million gallons of liquid waste,
constituting over one half (533 million curies) of DOE's high level
radioactivity. These wastes present large radiological, environmental, fire,
and other hazards.
The concentrated liquid radioactive waste by-product of the SRS
separations processes consists of a strongly caustic solution of nitrate
salts. An insoluble and highly radioactive metal oxide sludge is present in
some of the streams, which are designated as high heat waste. These waste
streams are pumped from the separations facilities to the liquid radioactive
waste handling facilities (waste tank farms). The low heat waste, which
contains a lower concentration of radionuclides, is sent to a tank farm
evaporator feed tank. Tank farm facilities consist of 51 underground waste
tanks with a nominal capacity of one million gallons each and currently
store 35 million gallons of liquid waste. The tank farms maintain four
evaporators (two are operational) for waste concentration, transfer
pipelines, 14 diversion boxes, 13 pump pits, and associated tanks and pumps
required for waste transfers.
After the liquid radioactive waste is transferred from the separations
facilities to receiver tanks in the tank farms, the insoluble metal oxide
sludge settles out, leaving a supernatant radioactive salt solution layer
above the sludge. When radioactivity in the waste has decayed sufficiently,
the liquid salt solution is decanted from the insoluble sludge fraction. The
decanted salt solution is then concentrated by evaporation to form a
concentrated slurry that is returned to storage tanks, where it is
solidified into a salt cake that contains aluminum, iron, manganese, mercury
lead, silver, barium, cesium, strontium, uranium, and plutonium.
The long-term plan for the management of the liquid radioactive waste
calls for dissolution of the aged salt cake, followed by decontamination of
the resulting salt solution. The decontamination process will consist of a
precipitation reaction followed by a filtration of the precipitated
radioactive isotopes. This is the in-tank precipitation (ITP) process, which
produces a liquid low level waste stream and a highly concentrated
precipitate. The low level waste will be treated for benzene removal and
transferred to a storage tank to await transfer to Saltstone. At the
Saltstone facility, the low-level waste stream will be combined with fly
ash, slag, and a limestone source to form a grout mixture. It will then be
poured into disposal vaults and allowed to harden into a waste form called
saltstone.
For the insoluble sludge fraction, the sludge is slurried and transferred
from the tank farms to the extended sludge processing (ESP) facility within
H-Tank Farm. This sludge slurry undergoes washing/settling cycles to wash
out soluble salts. The resulting wash water eventually goes into the H-Tank
Farm evaporator system and then through the ITP process. The highly
concentrated radioactive component of the waste, including both the metal
oxide sludge fraction and the precipitated radioactive isotopes from the
salt decontamination process, is transferred to the DWPF for vitrification.
This glass is then poured into large stainless steel canisters to produce a
high integrity waste form designed for permanent disposal.
FACILITIES
Defense Waste Processing Facility (DWPF)
DWPF is a 42,000 square foot facility that receives, treats, and
immobilizes alkaline slurries of aqueous high level waste from F and H Area
tank farms in a durable, borosilicate glass form for eventual disposal in a
geological repository. DWPF construction was completed in 1995; the facility
is in radioactive operations with sludge only. Based on current operating
plans and funding, high level waste processing would be completed in 25
years. Sixty-four canisters of vitrified high level waste were poured
between April 1 and September 30, 1996.
Saltstone
Saltstone consists of facilities 210-Z, the operations building, and
concrete disposal vaults of two sizes (60,000 and 120,000 square feet) that
are used to immobilize and dispose of decontaminated salt solutions from F
and H tank farms. These solutions contain low level radioactivity and heavy
metal ions. Immobilization is accomplished by mixing the solution with
flyash, cement, and slag and pouring it into large concrete vaults to
harden. The Saltstone vaults provide permanent disposal of the neutralized
waste material. Radioactive operation began in 1990. Over 300,000 gallons of
waste were processed between April 1 and September 30, 1996.
Tritium Facilities (232-H, 233-H, and 234-H)
The tritium facilities provide the United States with tritium processing
capabilities necessary for nuclear weapons production and non-weapon uses.
Three tritium facilities are used for tritium handling and storage. Building
232-H is 55,000 square feet and performs extraction and purification.
Building 233-H is 35,000 square feet and is used for loading and unloading.
Building 234-H is 46,000 square feet and provides shipping and receiving
functions. As part of the non-nuclear reconfiguration program, the tritium
mission from the Mound Plant is being moved to SRS, with mission startup
planned for 1995 through 1998.
Reactors (K, L, P, C & R)
The five production reactors are all heavy water moderated designs
ranging in power levels from 2,400 MWth to 3,000 MWth that were used for
production of plutonium, tritium, and miscellaneous isotopes.
The K Reactor facilities are currently shut down, with some of the
support facilities in operation. The mission for the K Reactor changed from
demonstrating and maintaining tritium production capability to placing it in
cold standby with no planned provision for restart. Six major functions of
the K Reactor will be maintained operable during cold standby, and the
equipment and components of K Reactor necessary to support the six functions
will be maintained operable. The six functions are to (1) provide property
protection of government-owned equipment and facilities, (2) maintain
facility habitability, (3) prevent the facility from becoming immediately
unrecoverable, (4) store and process contaminated moderator, (5) handle and
temporarily store irradiated fissile and hazardous material in the
disassembly basin, and (6) store unirradiated reactor fuel and other highly
enriched uranium (HEU) in the assembly area. Additionally, the equipment and
systems of K Reactor required to ensure environmental compliance will be
maintained operable, as well as the equipment and systems required by the K
Reactor technical specifications.
Although the K Reactor has been placed in cold standby, the assembly area
will continue to store unirradiated fuel assemblies, the disassembly basin
will continue to store and handle irradiated components prior to shipment to
the separations facilities or the burial grounds, the moderator storage
areas will continue to store contaminated moderator, and the purification
area will continue to treat contaminated moderator until the site inventory
has been processed. Unirradiated fuel assemblies will continue to be
handled, transported, and stored in the assembly area in the same manner and
locations as before.
The site inventory of contaminated moderator (except for moderator stored
in the C, L, and P Reactor storage tanks) will be consolidated in Phase I of
the moderator consolidation program in the K Reactor moderator storage
areas. Contaminated moderators will continue to be stored in the storage
tanks and stainless steel drums; however, in some cases, the moderator will
be stored in new locations. The contaminated moderator will continue to be
processed in the same manner as before. The next phase of moderator
consolidation will move the moderator presently stored in the C, L, and P
Reactor storage tanks to the K Reactor moderator storage areas.
Miscellaneous irradiated and unirradiated components (e.g., boron carbide
safety rods, instrument rods, sparjets, and other stainless steel and
aluminum reactor components) may continue to be stored in the process room
(i.e., inside the reactor tank), though none of these components are
susceptible to release of radioactive contamination.
L Reactor facilities are currently in limited operation. The mission for
L Reactor changed from demonstrating and maintaining tritium production
capability to placing the L Reactor in cold shutdown, with no capability for
restart. Although L Reactor was placed in cold shutdown, the disassembly
basin will continue to store and handle irradiated components prior to
shipment to the separations facilities or the burial grounds, the moderator
storage tanks will continue to store the contaminated moderator, the L-Area
low level waste compactor facility will continue to compact waste into
cardboard boxes for shipment to the burial grounds, and miscellaneous
irradiated and unirradiated components (e.g., boron carbide safety rods,
instrument rods, sparjets, other stainless steel and aluminum reactor
components) will continue to be stored in the reactor tank.
P, C, and R Reactor facilities are currently in limited operation. The
mission for P, C, and R Reactors changed from demonstrating and maintaining
tritium production capability to placing them in cold shutdown with no
capability for restart.
The P Reactor is in cold shutdown and irradiated fuel has been shipped to
other site facilities. The moderator storage tanks will store contaminated
moderator and miscellaneous irradiated components will be stored in the
reactor tank.
Although the C Reactor is in cold shutdown, the disassembly basin will
continue to store and handle irradiated components prior to shipment to the
burial grounds, the moderator storage tanks will continue to store
contaminated moderator, and miscellaneous irradiated components will
continue to be stored in the reactor tank.
The contaminated moderator is stored in drums in the R Reactor drum
storage building.
M Area Fabrication Facilities
The current mission for M Area facilities is to shut down reactor
materials production in a safe, environmentally sound manner; to treat
previously-generated mixed low level waste; and to prepare for the
transition of facilities to EM for decontamination and decommissioning. M
Area facilities are currently in limited operation. The status of M Area
facilities is:
- The Fuel Fabrication Facility (Building 321-M) is in operation,
although new fuel assemblies are not being fabricated. Activity in this
building consists of casting uranium aluminum alloy scrap and excess fuel
tubes into ingots which are more suitable for transport and storage.
Designation of 321-M to below hazard category 3 was completed at the end
of fiscal year 1996.
- A vendor-operated vitrification facility has been installed to treat
the mixed low level waste sludge previously generated by production
activities.
- Buildings 330-M and 331-M are warehouses used to store depleted
uranium cores and slugs. Deinventory options and costs are being evaluated
currently for these buildings.
Receiving Basin for Offsite Fuel
The RBOF, a spent fuel storage pool for research reactor fuels, is
operational. The mission of the RBOF is to:
- Receive, handle, and store irradiated nuclear fuel elements from
offsite power and research reactors, from foreign country reactors, and
from onsite reactors.
- Repackage nuclear fuel elements into containers and bundles for
extended storage and/or shipment to onsite or offsite reprocessing
facilities.
- Handle, separate, and transfer wastes generated from nuclear fuel
element storage.
The RBOF supports the SRS mission through the safe interim storage of
irradiated nuclear fuel elements from offsite and foreign reactors in
support of nonproliferation policy.
F Canyon
F Canyon is a 128,000 square foot plutonium and uranium separations
facility used to process plutonium and other materials for national defense
purposes. It has done so safely for over 30 years. With recent changes in
the world power structure, the United States no longer requires a
significant nuclear stockpile. Therefore, F Canyon is phasing out its
operation. F Canyon is currently operating a second plutonium cycle to
purify and concentrate Pu-239 for transfer to the FB Line; processing TRR
spent fuel and Mark-31 targets; storing other plutonium, uranium, and
americium/curium solutions awaiting restart authorization; and operating
nondiscretionary waste evaporation cycles to process canyon, analytical
laboratory, reactor, and related waste streams. The F-Canyon Outside Area
Facilities, including the FA Line, are a 37,500 are a square foot complex
providing support operations.
FB Line
The FB Line is a 55,000 square foot plutonium separations facility
constructed between 1951 and 1953 and expanded in 1958. FB Line is located
in Canyon Building 221-F. The FB Line currently stores plutonium and other
SNM in a safe configuration awaiting disposition. FB Line completed
implementation of a DNFSB 94-1 requirement by finishing stabilization of all
plutonium solutions. In addition, the stabilization of plutonium residues
commenced three months in advance of the DNFSB 94-1 implementation plan
milestone.
Naval Fuels
Naval Fuels is a 110,000 square foot enriched uranium fuel manufacturing
facility that was constructed in 1987. This facility is in a surveillance
and maintenance mode. The new mission of the facility has not been
identified. Process facilities are inactive and contain residual nuclear
material resulting from previous operations. Alternatives to facility
shutdown are being evaluated. Future modifications have not been proposed.
PUFF
PUFF is a 55,000 square foot facility containing Pu-238 hot cells that
are currently in cold standby. The current PUFF mission is to provide safe
storage of nuclear material resulting from nuclear weapons production and
other non-weapon uses. These facilities were originally designed and
operated to manufacture plutonium fuel pellets for the space program and
neptunium billets. These processes are currently deactivated. Future
modifications have been proposed for the facility (e.g. addition of a
californium shuffler and new vaults).
Building 235-F was constructed as part of the original Savannah River
Plant project in the mid-1950s. Subsequent expansions and modifications
included construction of PUFF. PUFF was used from the late 1970s to the
early 1980s to manufacture encapsulated Pu-238 oxide fuel forms.
In December 1983, DOE completed Pu-238 fuel clad production for NASA's
Galileo and Ulysses space missions at PUFF. PUFF was then placed in standby,
and failed equipment was left in place awaiting resumption of production.
The decision to place PUFF in standby was based on the belief that new fuel
clad requirements would soon be forthcoming, and production would begin in
fiscal year 1986. It was expected that once new fuel clad requirements were
identified, fuel clad production could be restarted quickly and at minimal
cost. For this reason, and because the hot cell design made cleanup
difficult without dismantling the facility, only a limited effort was
undertaken to decontaminate the process cells, and an indeterminate amount
of highly corrosive Pu-238 oxide powder was left in the cells.
Projected new fuel clad requirements did not materialize, and the
facility was left in standby. As staffing and budgetary limitations became
acute, cell equipment and the maintenance program deteriorated. After 1985,
with facility conditions continuing to deteriorate, neither the program
office, SR, nor the contractor revisited their original decision for limited
cell decontamination.
H Canyon and H Canyon Outside Facility
H Canyon is a 403,000 square foot facility used for plutonium
separations. Processing of depleted uranium fuel using the PUREX process
began in 1955. H Canyon remaining missions include, but are not limited to,
the processing of existing SRS reactor and RBOF fuels, the purification of
Pu-238, and the processing of stored Np-237 and Pu-239 solutions. The H-Area
Outside Facility provides support operations.
Old HB Line
The Old HB Line is a Pu-238 processing facility that was shut down in
1984. It produced Pu-238 oxide primarily for the space program as a heat
source to be used in generating electricity for spacecraft going into deep
space. It was upgraded throughout its existence, but in 1984 was replaced by
the new HB Line.
D&D of the Old HB Line facility began in 1984. The D&D efforts were
interrupted in 1986 because of a lack of funds. At that time, the scrap
recovery process and the shielding for the neptunium oxide process had been
removed. When the effort was resumed in 1988, the contamination in these two
areas ranged from 40 to 100 million d/m/.1 square meter alpha. On July 26,
1990, D&D work in Room 306 of the Old HB Line was curtailed when concerns
involving radiological control practices were raised. The concerns resulted
when four radiation workers in plastic suits with breathing air became
contaminated, during an emergency exiting of a highly contaminated area of
Old HB Line, due to the failure of the 221H breathing air compressor.
Further reviews of this incident resulted in stopping work in Room 306.
HB Line
HB Line is a 28,000 square foot plutonium processing facility constructed
in three phases during the 1980s. The HB Line plutonium processing
facilities are located on top of the H-Area Canyon Building 221-H and
include the Scrap Recovery Facility (Phase I) and the Plutonium Oxide
Facility (Phase III). The Frame Waste Recovery process is located within the
221-H building. The HB Line facility also houses a vault for the storage of
Pu-238 oxide product and scrap material.
Phase I provides a scrap recovery facility, where materials are dissolved
in nitric acid and transferred to H Canyon. There are two glove box lines
(North and South), of which only the North is operating.
Phase II provides the neptunium oxide facility, where Pu-239 and Np-237
nitrate solutions are received from H-Canyon and converted to oxide. Phase
II is not operating.
Phase III provides the plutonium oxide facility, where Pu-242 is received
from H Canyon and converted to oxide. Phase III is operating. The Old HB
Line is an abandoned plutonium processing facility currently undergoing D&D.
Old HB Line is contained within H Canyon and was operated between 1963 and
1984.
The HB Line was built on top of the canyon in the early 1980s, replacing
an existing facility (Old HB Line) located on the third and fourth levels of
the H Canyon. The HB Line facility operated between 1985 and 1987. These
operations were assessed in a 1991 environmental assessment, resulting in a
finding of "No Significant Impact" issued in July 1991. The HB Line resumed
operations, and, seven days after restart, operations in the HB Line were
suspended due to radiological contamination of five workers resulting from
conduct of operations inadequacies involving Pu-238 scrap stored in the HB
Line vault. Operations resumed in October 1991. One month later, operations
were again suspended due to an inadvertent transfer of zirconium within the
HB Line. Operations then resumed in December 1991. In March 1992, operations
in HB Line and H Canyon were suspended because of a safety question
concerning the air exhaust stack liner. Operations resumed in January 1993
and have continued to the present.
Savannah River Technology Center (SRTC)
SRTC is a complex of buildings primarily located in the 700 Area, with a
smaller limnology lab located on Par Pond. It is an applied research and
development organization that provides technical support for the mission of
SRS, working in partnership with site operations, and interfacing with other
government and private research organizations. The focus of SRTC is to
develop, test, and demonstrate equipment and techniques for nuclear material
processing, environmental remediation, environmental protection, was
processing, decontamination and decommissioning, and industrial uses of SRS
technologies.
Multipurpose Pilot Plant Campuses (MPPC)
For 45 years, the facility has been known as the TNX demonstration
facility. The facility, located in D-Area, consists of a wide range of
buildings and support structures totaling 135,000 square feet. No
radiological operations are conducted in this facility. The name of the
facility has been changed to MPPC, and efforts are under way to open the
campus to formal partners of WSRC for applied research and development
efforts. The MPPC was selected as a pilot project for the Necessary and
Sufficient process, and WSRC and SR are currently finalizing the Work Smart
standards for the facility.
Savannah River Ecology Laboratory (SREL)
SREL is a 50,000 square foot ecology laboratory constructed in 1977. Its
mission is to perform ecological studies.
Analytical Laboratories
The analytical laboratories provide radiochemical analytical process
control support for nuclear material stabilization (F and H Areas) and waste
management. Analytical support is also provided to site waste
characterization and environmental remediation programs. Radioactive
materials analyzed include plutonium/uranium isotopes and fission products.
Building 772-F is the main production support laboratory. Building 772-lF is
a support building. Building 772-4F is fully operational and provides a high
efficiency particle air filtered exhaust system for Building 772-F. Building
772-4F was constructed in the early 1990s when the 772-1F ventilation
exhaust system became contaminated by a leak in the high level laboratory
drains. 772-D is a 12,000 square foot analytical laboratory constructed in
1951. It is fully operational, providing radioanalytical process control
support for D-Area moderator rework facilities. It houses the capability to
analyze tritiated moderator for concentrations of heavy water, tritium, and
impurities.
Liquid Waste Handling Facilities (H-Area and F-Area Tank Farms)
These facilities are part of the High Level Waste Management Division,
whose mission is to safely receive and store liquid radioactive waste,
prepare the waste for processing, and to feed the prepared waste to DWPF and
Saltstone for processing into stable, inert solids, so that radioactive
materials will be effectively isolated from the environment. In addition,
these facilities treat the waste water effluent which is released. The
facilities are operational, with the exception of the replacement high-level
waste evaporator, which is under construction.
The H Area tank farm consists of an evaporator (241-16H), 23 waste tanks,
and transfer systems that are used for storage of high level nuclear waste.
The ITP and ESP facilities (6 waste tanks, filter/stripper building, cold
chemical feeds area, and transfer systems) are within the H Area tank farm,
and are used for nuclear waste processing.
The F Area tank farm consists of an evaporator (241-2F), 22 waste tanks,
and transfer systems that are used for storage of high level nuclear waste.
Solid Waste Management Facility (SWMF)
The SWMF provides storage of transuranic wastes, mixed wastes, and
nonradioactive hazardous waste materials and disposes of low level solid
radioactive wastes generated from production of nuclear materials for the
Office of Defense Programs. These facilities consist of a series of burial
grounds, vaults, and storage pads.
Burial Grounds
The 643-E Old Burial Grounds, operated between 1952 and 1972, are
currently undergoing Comprehensive Environmental Response and Compensation
Liability Act (CERCLA) review prior to final closure. The 643-7E Burial
Grounds operated from 1972 to March 1995. Various maintenance activities
(e.g., mixed waste storage and solvent tank closure) continue. The burial
grounds occupy 200 acres.
E-Area Vaults
These vaults are used for disposal of solid low level waste. They became
operational in 1994 and occupy 100 acres, including a 110,000 square foot
disposal area.
Transuranic Waste Storage Pads
Transuranic waste has been stored in containers on concrete pads since
1974. There are 19 storage pads occupying 114,000 square feet. The
containers on some pads are covered with soil, while others have weather
proof enclosures. The transuranic waste will eventually be retrieved and
characterized to determine if it can be disposed directly or if treatment is
necessary prior to disposal.
In-Tank Processing Facility (ITP)
The ITP is a 5,000 square foot nuclear waste processing facility that was
completed in 1995. In-tank processing operations have been delayed pending
the resolution of issues concerning the generation of benzene in the
processing tank. When the ITP is operational, wastes accumulated in the F-
and H-Area waste tanks are processed to produce a decontaminated salt
solution (primarily a chemical waste with trace radioactivity) for feed to
the Z-Area Saltstone facility and two different slurries that contain
concentrated radioactive materials (i.e., washed sludge and precipitate) for
feed to the S-Area vitrification plant. As the neutralized high-level waste
ages, gravity causes it to settle into a salt solution (supernate) over a
layer containing solids (sludge). In some waste tanks, some of the salt has
crystallized from the solution. Salt crystallization and, thus, volume
reduction is enhanced by concentrating the supernate in the waste
evaporators. The salt solution is decontaminated by the ITP using a batch
process.
Consolidated Incinerator Facility (CIF) 261-H
This facility is a 40,000 square foot incinerator constructed in 1995.
The CIF will provide a facility for the safe treatment by incineration of
combustible wastes (solids and liquids) that are defined as low-level
radioactive, hazardous, and mixed (containing both hazardous and radioactive
components) under the South Carolina hazardous waste management regulations.
The facility is currently undergoing preoperational testing.
Tritium-Producing Accelerator
Tritium is an essential component of nuclear weapons. This man-made gas
naturally decays to a form of helium and, therefore, must be replenished.
Currently, this is accomplished with tritium recycled from dismantled
weapons. However, fresh supplies will be needed by about the year 2007. To
meet this need for tritium, the Department of Energy (DOE) is studying two
separate technologies: the use of an existing commercial reactor and the
construction and use of a new linear accelerator. The Secretary of Energy
recently announced DOE's formal "Record of Decision" for the Tritium Supply
and Recycling Programmatic Environmental Impact Statement. In this
announcement, SRS was named the preferred site if an accelerator technology
is selected. The technology decision is to be made in 1998. DOE has selected
a linear proton accelerator for the production of tritium. This type of
accelerator is called a linac, short for linear accelerator. The tritium
production linac would be about a mile long, mostly underground.
Construction of the multi-billion dollar APT facility would create about
4200 construction jobs, on and off site. Operation of the facility would
require about 650 jobs. In addition, if existing utilities could not provide
the substantial electrical energy needed to operate the accelerator, a new
power plant would be built.
