Regulators' views are not exactly conclusive regarding this question:
- On Jan. 18, 2005, the U.S. Nuclear Regulatory Commission decided that depleted uranium is a low level waste - and the DU therefore may be transfered to DOE for disposition, as requested by the license applicant.
(view details)
- On Sept. 26, 2001, the Texas Department of Health approved the disposal of DU counterweights at a land burial facility not even licensed for disposal of radioactive waste, as requested by the license applicant.
(view details)
- On Nov. 5, 1998, a French appeals court, revoking a lower tribunal's decision, ruled that depleted uranium is no waste, but a "directly usable raw material that is effectively used for multiple uses" - and the DU therefore may be stored indefinitely in the form of U3O8 in purpose-built storage buildings, as requested by the license applicant.
(view details)
- On Oct. 22, 1997, the German government stated that re-enrichment of Urenco's tails in Russia is not connected to a management of residues violating international rules, standards, or obligations, though the secondary tails remain in Russia and their avoided disposal cost appears to be Urenco's main purpose for the re-enrichment deal.

DOE presents re-enrichment options for its higher assay depleted uranium tails
"DOE will consider the sale of DUF6 or re-enrichment to natural uranium or LEU to realize the best value for the Government. The DOE inventory of 75,300 MTU of DU having an assay from 0.35 percent 235U to 0.711 percent 235U is currently scheduled for conversion to a more stable form, followed by its re-use or disposal. However, as the price of NU has increased the value of the relatively higher assay DU makes it potentially attractive for reenrichment.
Enriched to 0.711 percent 235U, the DU could produce about 25,950 MTU of NU as UF6. DOE has estimated that the gross value of this uranium would be approximately $5.6 billion based on the April 2008 market price for uranium. The net value is estimated to be about $3.4 billion after re-enrichment, depending on the actual SWU price. 1" (Excess Uranium Inventory Management Plan, Dec. 16, 2008)
1 Uranium Exchange (Ux) Corporation's month end spot price of $78.00 per pound of U3O8, conversion price of $9.00 kgU, NU UF6 price of $215 kgU and SWU price of $143.
For the NU contained, DOE assumes an average DU assay of 0.366% 235U and a secondary tails assay of 0.20% 235U.

GAO urges DOE to hurry up with assessment of re-enrichment options for its depleted uranium tails
The U.S. Government Accountability Office (GAO) released a report urging the Department of Energy (DOE) to complete an analysis of the management options for its stocks of depleted uranium tails. GAO wants the DOE to consider the options for re-enrichment and/or sale of the unprocessed tails, to take advantage of the currently high market price for uranium.
Since DOE's legal authority to sell the unprocessed tails is doubtful, GAO moreover asks Congress to grant such legal authority.

DOE has agreed to transfer up to 8.5-million kilograms of depleted uranium to
the Bonneville Power Administration (BPA) for re-enrichment by USEC Inc. and use in Energy Northwest's (EN) Columbia BWR over the period 2009 to 2017. DOE
has some 700,000 metric tons of depleted uranium but only a small percentage
are at assays above 0.4% U-235 and therefore clearly economical in today's
market to re-enrich, according to a source familiar with what he described as
this "pilot" program. He said that if all 8.5-million kg were re-enriched, it
might generate about 1.9-million kg of natural UF6, and could save EN millions
of dollars in fuel costs if today's UF6 prices remain at current market levels
(about $87.25/kgU as UF6). But the actual feasibility of recycling DOE's
depleted UF6 for use in a commercial reactor has not been tested, he said,
given questions over how much of the depleted uranium is contaminated with
unwanted radioactive isotopes. This pilot project will provide DOE with the
information to support a decision regarding any subsequent action to reuse any
of the remaining DUF6 inventory, he said.

Rosatom confirms termination of re-enrichment of imported depleted uranium tails in 2011
Rosatom confirmed that the re-enrichment of foreign depleted uranium tails will be terminated in 2011. The current contracts expire in 2009 and 2010, and they won't be renewed, nor will any new contracts be concluded, a Rosatom expert confirmed.

Russia to terminate re-enrichment of imported depleted uranium tails, once current contracts expire
Over a year ago, Rosatom, the Russian Federal Atomic Energy Agency, decided not to sign new contracts for imports of depleted uranium from Europe for enrichment and plans only to implement contracts signed in the 1990s, Atomic Energy Agency Director Sergei Kirienko told journalists in Angarsk.
"We decided over a year ago that we would not sign new contracts or
extend old ones, but we cannot tear up agreements that we already have -
they expire in 2009-2010," he said.
"We consider it incorrect to import hexafluoride until the issue of its potential chemical danger is resolved," Kirienko said.
Kirienko said that contracts to import depleted uranium from Europe were signed in the 1990s "at a good price."

Protest in Moscow against import of depleted uranium tails from Germany to Russia
On Oct. 12, 2006, environmentalists staged a brief protest in front of Germany's embassy in Moscow against long-standing shipments of German nuclear waste to Russia.
Brandishing a banner scrawled with "Stop the entry of nuclear waste", a dozen Germans and Russians demonstrated for about 10 minutes before the
Russian protesters were seized, handcuffed and hauled away by police.
"German authorities must stop burying radioactive waste in Russia which
threatens the health of future generations of Russians," Vladimir Sliviak of
the Russian environmental group Ecodefense, said in a statement.
"German authorities must not take advantage of the fact that the Russian atomic industry can violate laws and ignore public opinion," he added.
According the Ecodefense, some 100,000 tons of nuclear waste have been imported
to Russia over the past decade. Up to 90 percent of the waste is stored by
Russian companies, awaiting final disposal, the group said.
The radioactive material arrives in Saint Petersburg's port in the northern part
of the country, Ecodefense said, where it is carried by train toward the Ural
mountains, and western and eastern Siberia.

Russia could expand re-enrichment of foreign depleted uranium tails
Russia could increase its share of the global market for the treatment of depleted uranium to 45% by 2010, from 40% at present, Vladimir Korotkevich, director of the state-owned Siberian Chemical Combine at Tomsk, told reporters. He also said that Techsnabexport, the Russian government's authorized exporter of nuclear materials and nuclear power plant fuel, had contracts worth more than $3 billion annually to process depleted uranium hexafluoride from abroad. This does not include contracts signed under the Megatons to Megawatts deal with the United States.

At Cherbourg, activisits block train carrying depleted uranium hexafluoride destined for Russia
On Jan. 24, 2010, members of Greenpeace and other anti-nuclear organizations chained themselves to a railway track to halt a transport of nuclear material destined for export to Russia. According to Areva, the transport comprises 480 tonnes of depleted uranium and 170 tonnes of natural uranium originiating from Areva's Pierrelatte plant. Areva maintains that the depleted uranium is no waste, since it is to be re-enrichred in Russia.

Protest in St Petersburg against arrival of depleted uranium shipment from France
On Dec. 11, 2008, ecologists from the local branch of Bellona, an international environmental pressure group Bellona protested outside the French Consulate General in St. Petersburg as cargo containing toxic uranium derivatives arrived in the city's port.
The hazardous cargo arrived in St. Petersburg on board the Zamoskvorechiye, a ship belonging to French company Eurodif which is carrying containers holding a total of 2,000 tons of depleted uranium hexafluoride from the Tricastin Nuclear Power Center in Pierrelatte, France. The ship left the French port of Havre on Dec. 4.
For about two hours, six protestors picketed the French consulate one at a time to avoid laws against unplanned free association of people in public places.

Greenpeace blocks depleted uranium export to Russia at Le Havre (France)
On Dec. 1, 2005, Greenpeace France blocked a transport of 450 t of uranium wastes at Le Havre. The material was to be exported to Russia. It consisted mainly of depleted uranium, to be re-enriched in Russia, and possibly some reprocessed uranium (RepU) (view details), to be swapped to natural uranium. It had arrived by train from the enrichment plant at Pierrelatte, and was to be loaded on the container ship "Kapitan Kuroptev" for sea transport to St Petersburg. (Greenpeace France, Dec. 1, 2005)

Vladimir Korotkevich, director of the state-owned Siberian Chemical Combine at Tomsk, where some of the re-enrichment takes place, alleges this blockade was initiated and paid for by competitors of the Russian enrichment facilities(!) (Interfax Dec. 28, 2005). This allegation shows, what serious blow the dragging of the re-enrichment business into the limelight presents to the Russian enrichers...
Cogema ships about 7,000 MTU [metric tonnes U] of tails (at an assay
of about 0.35%) to Russia each year, according to an RWE
Nukem analysis. In addition to 1,100 MTU of natural
uranium, Cogema also receives back about 130 MT of low-enriched
uranium at an assay of about 3.5% U-235. (Nuclear Fuel May 12, 2003)
> For details on this issue, view the report "Re-enrichment of West European Depleted Uranium Tails in Russia".
Cogéma sends "a very small percentage" of the enrichment tails of its Eurodif plant to Russia for re-enrichment. (Nuclear Fuel Dec. 28, 1998)
"Minatom/Tenex has an estimated 9-million SWU/year of enrichment production capacity in excess of Russia's needs. If Russia uses the 9-million
SWU to strip tails from Urenco and other Western enrichers with 0.30%
uranium-235 to 0.20% U-235, it would produce 29 million lb of uranium
oxide (U3O8) (11,180 tonnes U) per year. It is likely, according to George
White, a consultant with Uranium Exchange Co., the Russians have contracted
with Urenco to strip tails from 0.3% to 0.25% U-235. But then the Russians
probably stripped the tails further, to 0.12 U-235, to produce uranium
for their own account and selling it, White suggested. Stripping of
uranium tails in this way would reduce the need for natural uranium
by about 30%." (WISE NEWS COMMUNIQUE 502, November 13, 1998)
If Russia used its excess 9 million SWU/year to strip Urenco's tails in the described way from 0.3% to 0.12% U-235, 7290 tonnes/year of uranium of natural isotope composition would be recovered, 4680 tonnes of which on Russia's own account.

From a press release of Edlow of June 16, 1998:
" Using a chartered ocean vessel, Edlow International Company delivered
140 cylinders of depleted uranium to Russia on May 29, 1998. Shipped in
48 inch cylinders, the shipment consisted of 461,871 kilograms uranium
hexafluoride (UF6). Originating in South Africa, the shipment is
significant as it represents half of South Africa's depleted UF6
inventory. The remainder of the country's depleted UF6 will be shipped
to Russia at a later date.
This shipment was performed by Edlow International under contract to
Edlow Resources Ltd. (an Edlow family company) in connection with Edlow
Resource's purchase of 2,000 tonnes of depleted UF6 from the Atomic
Energy Corporation of South Africa (AEC). The AEC has no remaining use
for the material, as it closed its enrichment facility - the Z plant -
in March 1995.
The depleted UF6 will be re-enriched in Russia and the resulting
enriched product will be sold to electricity utilities for use in
commercial nuclear power generation. As such, the transaction represents
a positive use of what is often regarded as a waste product."

The centrifuge enrichment plant of
Minatom's Ural Electrochemical Integrated Plant (UEChK, formerly Sverdlovsk-44) at Novouralsk near Ekaterinburg is now
enriching tails for Urenco. The tails
are enriched to a natural uranium equivalent level of 0.71% U-
235. In 1996, more than 6000 metric tonnes of tails were upgraded.
[Nuclear Fuel, October 6, 1997]
In 1998, 2,228 metric tonnes of tails were exported to Russia from Urenco's Gronau (Germany) plant alone [Nuclear Fuel, Feb. 21, 2000].
According to Euratom Supply Agency's Annual Report 1998 (p.10),
"Re-enrichment of western origin tails in Russia [...] provides a supply in the order of 1 000 to 2 000 tU (natural uranium equivalent) per year."
If Scenario 1 is assumed for the mass balance, this means that 13,600 to 27,200 t depleted UF6 would be shipped to Russia per year - two to four times the amount reported for 1996. As a by-product from the re-enrichment of this amount of material, 12,100 to 24,200 t of secondary tails would be produced per year.
For the production of the above amount of depleted UF6, Urenco would have to expend a separative work of 5.9 to 11.8 million SWU - much more than its present capacity of 3.4 million SWU. It can, therefore, be concluded that Urenco is currently in the process of drawing down its depleted UF6 inventory at high pressure.
According to Euratom Supply Agency's Annual Report 1999 (p.10), "In 1999, deliveries of re-enriched tails to EU utilities represented some 800 tU."
According to Euratom Supply Agency's Annual Report 2000 (p.9), "Re-enrichment in Russia for EU enrichers of western origin tails continued in 2000. Deliveries of re-enriched tails to EU utilities represented some 400 tU under purchasing contracts plus 700 tU acquired through exchanges. The Agency concluded 4 new supply contracts for the delivery of about 600 tU as re-enriched tails over the period 2001-2005."
According to Euratom Supply Agency's Annual Report 2001 (p.17), "some 1050 [tU] were delivered to EU utilities following the re-enrichment in Russia of tails on behalf of European enrichers", and "3 new supply contracts for the delivery of 760 tU as re-enriched tails in 2002-2004 have been concluded".
"A report presented earlier this year [2003] at a World Nuclear Association working group meeting by an RWE Nukem analyst, suggested that Urenco ships about 7,000 metric tons (MT) U of tails (average assay 0.30% U-235) to Russia for re-enrichment every year and receives back about 1,100 MTU of natural uranium."

According to the answer of the German government (BT-Drs.
13/8810 ) to a parliamentary question of the Greens, the new
tails produced during this upgrading process remain in
Russia.
Since the upgrading process results only in a minor reduction of
the amount of tails, Urenco's main purpose of the deal seems to
be to get rid of its waste management problem.
The Federal Government, however, stresses the results of an
investigation it has conducted together with the governments of
the United Kingdom and the Netherlands. The study has approved
that the re-enrichment in Russia is not connected to a
management of residues violating international rules, standards,
or obligations.
But, this view must be questioned, since the tails upgrading
does not make an economic sense, if the recovery of the uranium
were its only purpose: under current market conditions, the
recovered uranium would be 68% more expensive than fresh
uranium, and Urenco would incur a loss of $1700 per t UF6 sent to Minatom. *)
The re-enrichment does, however, make sense, if the avoided
disposal cost for the tails in the proposed Gorleben HLW deposit
are taken into consideration (the German LLW deposits don't
allow for storage of such amounts of uranium). The excess
upgrading cost over the market value of the uranium recovered
would be about 10% only of the storage cost at Gorleben, and Urenco would make a profit of $17300 per t UF6 sent to Minatom. *)
*) These figures are calculated on current market prices,
a product assay of 3.6% (PWR grade) and a tails assay of 0.3% at
Urenco [IAEA 1996 Red Book], and an assumed tails assay of 0.25%
at Minatom. The upgrading process would reduce the amount of
tails by 10% only under these conditions. The storage cost for a
200-liter barrel at the Gorleben HLW deposit is estimated at
15,000 DM; the volume needed for disposal of the tails as UO2
after cementation in barrels is estimated at 550 litre/t
UO2.

The plant, located in the St. Leon Business Park north of Idaho Falls, Idaho, is now nearly complete.
The NRC operating license is required before the Company may store and process sufficient quantities of depleted uranium tetrafluoride (UF4) to support commercial scale fluoride gas production and is the last license or permit required before the company can begin commercial fluoride gas production.

International Isotopes Inc. applies for operating license for Fluorine Extraction Process (FEP) production plant project, Idaho, USA
On April 21, 2005, International Isotopes Inc. submitted an application to possess and utilize depleted uranium (DU), solid form as uranium tetrafluoride (UF4) or uranium oxide (UO2 or U3O8). The company requests to receive and to store up to 5000 kilograms of DU per year with an additional 1000 kilograms of DU in process equipment. The proposed licensed activity will be to produce high purity fluorine gas compounds, such as germanium tetrafluoride (GeF4) or boron trifluoride (BF3). This robust chemical reaction converts UF4 into U3O8/UO2 during the fluorine gas production process.

Hydrofluoric acid enters Tricastin site cooling water system
On Sep. 13, 2007, a significant amount of hydrofluoric acid entered the cooling water circuit at the deconversion plant for depleted uranium "Usine W". The cooling water system is serving the whole Tricastin site. Due to the cooling water becoming corrosive, several small leakages of the cooling water system were observed. After assuring the security of the plant and the employees, the cooling water system was emptied. The acidic water recovered was treated and released, leading to an exceedance of permitted short term release limits. Preliminary assessments suggest that the environmental impact of the event was not significant.

Depleted uranium hexafluoride leak from corroded legacy cylinder demonstrates urgency for tails disposition at Sellafield Ltd's Capenhurst site
"On 24th July [2009], the licensee promptly notified NII of a seepage of a few litres of radioactive liquor from a corroded stored uranium hexafluoride legacy "Hex Tails" cylinder, held inside a storage building. The Site Emergency Control Centre was appropriately manned for several hours, whilst the leak was promptly brought under control and sealed by the 'on site' Fire & Rescue team. There was no escape of radioactivity from the building and no personnel were contaminated. The volume (about three litres) and specific radioactivity of the acidic liquor, which had leaked from the ageing "Hex Tails" cylinder in a small localised area, breached the level defined within the Ionising Radiations Regulations 1999. [...]
This event has clearly significantly enhanced the need for timely "Hex Tails" disposition and NII will continue to press for the development and timely implementation of detailed plans for elimination of the "Hex Tails" hazard from the Sellafield Limited site at Capenhurst."

COVRA opens new uranium oxide storage halls for depleted uranium from Urenco's Almelo enrichment plant
"On the 2 July 2008, COVRA (the national storage facility for radioactive
materials in the Netherlands) opened two additional storage halls for storing
Urenco's depleted uranium at its facility in Vlissingen in the Netherlands.
Since the COVRA opened the depleted uranium building in 2004, its first
hall is now almost at full capacity. With the opening of these new halls,
availability of safe, long-term, retrievable storage of depleted uranium will
be ensured for years to come.
As part of Urenco's commitment to safety, it uses COVRA's facilities to store
depleted uranium from the enrichment process. Depleted UF6 is sent to
a facility in France, where it is converted to U3O8, a more stable form of
uranium and therefore suitable for long term storage. COVRA takes over this
material from Urenco, which is then shipped to Vlissingen in steel containers
each of which holds 10 metric tonnes of U3O8.
Each hall holds a maximum of 650 containers, which will provide safe,
reliable storage of the oxide for a further 100 to 150 years. Many years in
the future, a decision will be made by COVRA as to whether the material
can be reused or needs to be put into final storage."

Together with the application to increase the enrichment capacity of its Gronau, Germany, enrichment plant to 4000 tonnes SWU/year (details here), Urenco has filed an application for the construction of two storage buildings for its depleted uranium waste. The depleted uranium is currently being stored as uranium hexafluoride in cylinder yards next to the plant with a licensed capacity of 38,000 tonnes of UF6. For storage, the depleted uranium is to be converted to the more stable form of U3O8 at the Pierrelatte facility in France. The buildings are to be designed for a capacity of 50,000 tonnes of uranium oxide. (Gronauer Nachrichten, April 30, 1999; Westfälische Nachrichten July 31, 1999)

The long history of disposal of any kinds of wastes on former
uranium mine and mill sites is being enriched by a new project:
France's nuclear fuel company COGEMA
is going to store 199,900 tonnes of depleted uranium (DU) at the
site of the former uranium mill of Bessines-sur-Gartempe (Haute
Vienne) near Limoges. The project was licensed on 20 December
1995.
This license was revoked by the Administrative Tribunal of Limoges on July 9, 1998. The license was revoked mainly for the reason that the DU has to be regarded as a waste under current conditions, though an extraction of the residual uranium-235 might be viable in the future.
On Nov. 5, 1998, a Bordeaux appeals court ruled that the material is no waste, but a "directly usable raw material that is effectively used for multiple uses". Following this court decision, COGEMA sent the first DU shipment to Bessines on Nov. 12, 1998.
On May 23, 2001, the Conseil d'Etat finally turned down the appeal of the environmental organization ADEPAL against the Bordeaux appeals court ruling. The Conseil d'Etat followed the appeals court's ruling that the material is not a waste. ADEPAL was sentenced to pay 20,000 Francs (US$ 2,600) in damages to COGEMA.
At the time of this ruling, five of eleven storage buildings have been completed and 32,600 tonnes of depleted uranium have already been stored. (Info Nucléaire May 31, 2001 )
Originally, COGEMA had applied for the storage of 265,000
tonnes, but during the hearings held on the project, it became
obvious that COGEMA had "forgotten" to consider some
radionuclides in its calculation of the total activity
inventory: The specific activity of the depleted uranium is
21,100 Bq/g instead of 15,902 Bq/g. The project would therefore
have exceeded the 100,000 Curie limit, requiring a different
type of license (Installation Nucléaire de Base)
involving wider public participation.
During a public enquiry, conducted between 18 Nov 1994 and 2 Jan
1995, 10,182 citizens and organizations had voted against the DU
disposal project at the Bessines site.
A review panel (commission d'enquête) that was installed
to conduct a public enquiry on the project and to produce a
recommendation on it, followed the main views of the opponents
and issued a recommendation against the proposed
project on 23 March 1995. The reasons for this vote were the
neglected existence of artificial uranium-236 in the enrichment
wastes and the thus too high total inventory of the deposit that
would have exceeded the 100,000 Curie limit, among others.
COGEMA was not able to provide a reasonable explanation for the
presence of the uranium-236.
The depleted uranium is a residue of the Eurodif Tricastin
gazeous diffusion enrichment plant in the Rhône valley.
Its residual contents of uranium-235 is 0.2 to 0.3 % and it has
the chemical form of uranium
hexafluoride (UF6). But, COGEMA doesn't declare
it a waste, but wants to store it for possible future use.
COGEMA hopes that the stored DU can be useful, if future
enrichment techniques would allow for economic extraction of the
residual uranium-235, or if uranium prices would rise
significantly.
For storage, the UF6 is to be converted to the
chemically more stable form of U3O8 at
COGEMA's Pierrelatte facility. Then it is to be transported by
rail to the Bessines site and to be stored as a powder in iron
containers. The containers (8.5 or 11 tonnes each) are to be
stored in 11 special storage buildings of 3000 m2
each, according to the original plan. Each building can store
2500 containers. The maximum dose that an individual would be
exposed to at the fence of the facility, is calculated at 0.7
mSv (70 mrem) per year, far below the (extremely high) French
limit of 5 mSv (500 mrem) for the public.
The Bessines uranium mill has ceased operation in july 1993,
since the associated uranium deposits are worked out or cannot
be mined any more under the current uranium market conditions.
So the area now faces high unemployment of former miners, and
any kind of new business is welcome. Knowing this, COGEMA now
offers to build that DU disposal facility. The total investment
is planned at 60 million French Francs (approx. US$ 10 million)
over a period of 15 years.
The storage of DU at the Bessines site is only the first of a
series of proposals made by COGEMA: others are for the
treatment and storage of thorium-wastes from the Cadarache
facility, treatment of mercury-containing wastes, and storage of
natural uranium (yellow cake).

Savannah River Site completes depleted uranium metal shipments to Utah disposal site
The Savannah River Site has completed the final shipments of depleted uranium metals from an old manufacturing area at the complex, clearing the way for demolition of six buildings.
The M area buildings were the facilities where "target" materials for the site's five reactors were manufactured (The reactors produced plutonium for nuclear weapons).
Between March and June 2003, more than 2,600 metric tons of depleted uranium metal were shipped from the Savannah River Site to the Envirocare of Utah disposal site.
Officials also plan to ship 3,270 drums of depleted uranium oxide to EnviroCare in summer 2003 as part of a pilot program. The remaining 33,000 drums would be shipped during the next few years.

SRS uranium storage raises concern
A federal review board has questioned whether uranium is being stored safely at Savannah River Site.
The Defense Nuclear Facilities Safety Board found that depleted uranium is being stored in corroded drums and in deteriorating buildings at the federal nuclear-weapons site.
In some cases, wooden pallets supporting stacked drums of uranium had rotted, and "significant numbers" of the drums had tilted, the board wrote.
The board also raised concerns that uranium was stored in wooden crates and cardboard boxes, increasing the risk of a fire that could affect public health beyond the boundaries of the 310-square-mile (803 km2) site.
The U.S. Department of Energy stores about 24,200 tons (21,954 tonnes) of depleted uranium at SRS.
According to the board, little progress has been made in addressing the potential safety issues which were first identified in October 1998.

The stored material had been processed from depleted UF6 to U3O8 by Usine W to obtain a material suitable for safer long-term storage. The strong rise of the market price of uranium now obviously makes the re-enrichment of this depleted uranium economically feasible (see also Depleted Uranium Value Calculator). For re-enrichment, the depleted uranium first has to be converted back from the oxide form to the hexafluoride form. It is unclear, where the re-enrichment of the re-fluorinated DU is performed.

U.S. NRC leaves low-level waste classification of depleted uranium unchanged, initiates rulemaking for near-surface disposal
In a Staff Requirements Memorandum issued March 18, 2009, the Nuclear Regulatory Commission accepted the staff's recommendation that the agency continue to consider depleted uranium as Class A low-level waste (that is the least hazardous category), but amend regulations in 10 CFR Part 61 to require a site-specific analysis for the disposal of large quantities of depleted uranium and the technical requirements for such an analysis. The Commission also directed the staff to develop a guidance document for public comment that outlines the parameters and assumptions to be used in conducting the site-specific analyses.
In a dissenting vote, Commissioner Jaczko rather called for a (re)classification of depleted uranium (so far, depleted uranium is not listed and therefore by default considered Class A): "The disposal of large quantities of depleted uranium (DU) is a unique challenge because, unlike typical low-level waste, the doses increase over time rather than decrease."

Radiation expert blasts EnergySolutions for misleading public on hazards of DU disposal at Clive
The former chairman of the Radiation Control Board says EnergySolutions is misleading the public. Geochemist Stephen Nelson says the company falsely portrays its critics as anti-nuclear activists who don't know science.
"Well, I am, in fact, not opposed to nuclear power," Nelson says.
He's also an expert on radioactive isotopes.
"What I am for is the proper disposal of the byproducts of nuclear power," Nelson says.
He says the proper place for depleted uranium is a deep geologic formation, like a New Mexico salt deposit that will entomb the waste for millions of years. The wrong place, he says, is EnergySolutions' shallow landfill.
"I just don't think that squares with good science or with common sense," Nelson says.
He says the company falsely portrays the waste as benign, like natural uranium. In 50,000 years, he says it will be 13 times more radioactive.
Geochemist Stephen Nelson says the wrong place, he says, is EnergySolutions' shallow landfill in Tooele County.
Nelson's nightmare scenario is a dramatic rise in the Great Salt Lake. If Lake Bonneville returns, just enough to flood the north end of the Salt Lake Valley, it will also flood the landfill 60 miles to the west.
Nelson says that scenario is likely sometime in the next 100,000 years.
"There's a virtually 100 percent probability," he says.
An aerial photo shows Lake Bonneville once cut a bench 100 feet wide into solid bedrock. The landfill cover of concrete and rock, Nelson says, wouldn't stand a chance of holding radioactive waste in place.
"There's a very good chance that those piles would be very rapidly obliterated," Nelson says.

Depleted uranium to be disposed in Clive might contain reactor waste concentrations in excess of state limit
A Utah environmental group has scheduled a meeting with Gov. Gary Herbert to press its case that more testing is needed to make sure depleted uranium coming to Utah is not too hot.
HEAL says it reviewed shipping papers for some Savannah River, S.C., cleanup waste already in Utah and discovered that the DU, as depleted uranium is often called, contains reactor waste in concentrations that might top the radiological hazard limit set in state law.
But, according to the group, it's hard to say for sure because the U.S. Energy Department has sampled too few of the DU drums from its Savannah River cleanup in South Carolina -- just 33 of 33,000.

Protest held against depleted uranium shipment to Clive disposal site
Two dozen protesters braved the cold Saturday (Dec. 19) morning to protest plans to ship more than 3,000 tons of depleted uranium through the state to Utah's western desert.
The protest was organized by the Healthy Environment Alliance of Utah as a train carrying the first of three planned shipments of depleted uranium nears the state.
"We cannot allow this waste to be buried here, and we are asking Gov. Herbert to help us turn these trains around," said Christopher Thomas, policy director for HEAL Utah.
Thomas said a compromise worked out between Gov. Gary Herbert and the U.S. Department of Energy Thursday is inadequate.

DOE agrees to suspend depleted uranium disposal at Clive
The Department of Energy said Thursday (Dec. 17) that it has struck a deal with Utah Gov. Gary Herbert that would prohibit radioactive waste from South Carolina from being permanently buried in Utah until stricter state guidelines are put in place.
The first train, carrying 5,408 55-gallon drums of waste, won't be stopped or turned around, DOE spokeswoman Jen Stutsman said. But the DOE agreed to place its waste in temporary storage once it arrives in Utah, rather than permanently disposing of it.
The waste is expected to arrive in Utah in the next two weeks.
Stutsman said Utah regulators will have two months to develop new guidelines for disposing of the material. During that time, the empty train will make its way back to South Carolina to load up more waste. In all, nearly 10,000 metric tons of depleted uranium will be disposed of in Utah. The final two rail shipments are expected to be completed by late spring, but they won't leave for Utah until the new disposal guidelines are set.

Utah asks U.S. DOE to halt depleted uranium shipment to Clive disposal site; DOE goes on unimpressed
Utah Gov. Gary Herbert is sending Energy Secretary Steven Chu a letter asking him to halt the shipment of nearly 15,000 drums of low-level radioactive waste from South Carolina for disposal in Utah.
Herbert says the Department of Energy is circumventing state regulators' efforts to ensure a private disposal facility in Utah's west desert can safely dispose of the depleted uranium.
(AP Dec. 15, 2009)
Despite Gov. Gary Herbert's eleventh-hour plea to stop it, the first shipment of depleted uranium is expected to arrive in Utah before the end of December. The first of three planned rail shipments has left the site and will reach Utah in the next two weeks. The second and third shipments are slated for 2010, according Energy Department spokesman James R. Giusti.

DOE ready to start shipments of depleted uranium for disposal in Utah, inspite of ongoing rulemaking process
A Department of Energy official on Thursday (Dec. 10) informed U.S. Rep. Jim Matheson, D-Utah, that 11,000 tons of the low-level radioactive waste -- packed in 14,800 drums -- is ready to be shipped from the Savannah River cleanup in South Carolina.
Rubbish from bomb-making and enrichment, the Savannah River waste will be buried at EnergySolutions Inc.'s specialized landfill in Tooele County. Both state and federal regulators are looking at what measures are needed to make sure shallow disposal sites like EnergySolutions' can safely contain large amounts of DU, as depleted uranium is often called.
In its decision Thursday, DOE cited a Dec. 1 letter by Utah Director of Environmental Quality Amanda Smith, who noted that EnergySolutions is licensed to accept DU even as the state updates its site-safety requirements for DU over the next few months. Smith said she had not seen the letter informing Matheson about the imminent shipments.

Utah's Radiation Control Board is moving forward with efforts to require a company that wants to dispose of depleted uranium in the state to first submit a report confirming that additional safeguards will work.
The board voted Tuesday (Nov. 10) to develop new rules requiring EnergySolutions Inc. to complete a "site performance assessment" before additional depleted uranium comes to Utah.
The rule-making process is expected to take up to 120 days.
Nearly 15,000 drums of the low-level radioactive waste were slated to start arriving in December at the company's facility about 70 miles west of Salt Lake City.
But the company doesn't expect the updated assessment to be done until December 2010.

Shallow landfill disposal of depleted uranium at Clive "absurd", geologists say
Three scientists say federal nuclear regulators owe Utahns an apology -- and a policy change -- for allowing shallow burial of depleted uranium, including the 49,000 tons already at EnergySolutions Inc.'s landfill in Tooele County.
Geologist Stephen T. Nelson and climatologist Summer B. Rupper, both of Brigham Young University, and Kansas State University geologist Charles G. Oviatt, say it is "absurd" for the U.S. Nuclear Regulatory Commission to deem depleted uranium safe for surface disposal.
The uranium enrichment waste gets increasingly hazardous for a million years, and that's too long to reasonably ensure the safety of any shallow landfills, especially one like the Tooele County site that is underwater a few hundred of every several thousand years. Those wet cycles could spread long-lived radioactive material throughout the Great Salt Lake basin, the scientists say.
All three scientists, none of them speaking for their universities, are experts in the geological history of Lake Bonneville -- the massive water body that has periodically covered parts of three states in the past 30,000 years but now has receded to the present-day Great Salt Lake.

Public comment invited on Utah's proposal to impose additional conditions on depleted uranium disposal at Clive, until NRC's rulemaking process on DU disposal is completed - cancelled
"The Nuclear Regulatory Commission (NRC) has acknowledged
some inadequacies in its past analyses and possibly its current regulatory structure
with respect to disposal of substantial quantities of depleted uranium (DU). As a
result, it has started a rulemaking process (view details) to determine the conditions under which
DU and other unique wastes may be safely disposed of in near surface facilities. NRC has stated that new regulatory standards and guidance will be the likely
result from that rulemaking process, and that new performance assessments will
likely also be required. Rulemaking by the Division of Radiation Control (DRC)
would also likely be follow.
EnergySolutions has indicated to the Division that it
would prefer not to wait until the completion of the NRC's and DRC's
rulemaking processes or until completion of the resulting performance analysis
that will likely be required before it begins to dispose of depleted uranium at the
Clive facility. The additional license conditions in this Condition 35 are therefore
required."
Written comments will be accepted until the close of business on November 25, 2009.
On Nov. 12, 2009, the Division of Radiation Control announced that the public comment period has been cancelled due to actions taken by the Radiation Control Board at its November 10, 2009 meeting (see above).

Utah rejects moratorium on disposal of depleted uranium
State officials Tuesday (Sep. 22) rejected a plea to place a moratorium on any more depleted-uranium shipments to an EnergySolutions site in Tooele County, possibly clearing the way for shipments next month of the radioactive waste.
But the state still could require the company to remove the waste in the future.
In an 8-3 vote, the Utah Radiation Control Board rebuffed a request from the anti-nuclear-waste group HEAL Utah to halt such shipments until the federal Nuclear Regulatory Commission finishes a three-year examination of whether depleted uranium should be reclassified on the nation's radiation danger scale.

Rep. Matheson asks Energy Department to halt depleted uranium shipments to Utah disposal site
With the likelihood that nearly 15,000 barrels of depleted uranium may be headed to Utah, Rep. Jim Matheson on Wednesday (Sep. 16) asked the Energy Department to suspend disposal of the radioactive material until scientists can further study the effects of its long-term storage.
The Energy Department plans to ship about 14,800 barrels of depleted uranium -- which becomes more hazardous over time -- to Utah's EnergySolutions facility in Clive as part of the cleanup of the department's Savannah River Site in South Carolina.
"Depleted uranium -- as it decays -- actually becomes 'hotter,' remaining dangerous for tens of thousands of years," Matheson said in a statement. "That raises concerns for me, when the facility here in Utah is engineered to store Class A waste with a radioactive life span of 100 years."

More depleted uranium to be disposed in Utah, while state still ponders moratorium
Even as state regulators consider a moratorium on new shipments of the radioactive material -- which becomes more hazardous over time -- the U.S. Department of Energy plans to ship another 14,800 barrels of it to the EnergySolutions Inc. disposal site in Tooele County.
Part of the $1.6 billion in federal stimulus money for the Savannah River cleanup site in South Carolina will pay for rail cars filled with depleted uranium to be buried in Utah during the next 13 months.

Utah Radiation Control Board ponders moratorium for depleted uranium disposal at Clive LLRW disposal site
A half dozen Utahns urged regulators to demand that the long-term safety of residents is assured before allowing any more depleted uranium to be buried in the state.
The message, part of an organized effort by the Healthy Environment Alliance of Utah (HEAL), landed before the Utah Radiation Control Board on Tuesday (May 12, 2009). And the panel asked its lawyers to begin looking at the legal implications of imposing a moratorium on the low-level radioactive waste (LLRW) disposal until that assurance can be made confidently.
EnergySolutions Inc.'s low-level radioactive waste-disposal site in Tooele County has accepted about 49,000 tons of depleted uranium over about two decades.

According to DOE spokesman John Shewairy, the depleted uranium coming to Oak Ridge will be used for downblending the stockpile of fissionable U-233 currently housed at ORNL's 3019 facility. The special nuclear material is being downblended to eliminate its weapons potential and prepare it for disposal as waste.
(Knoxnews Aug. 7, 2009)
"EM is responsible for surplus uranium-233 at various sites; the largest quantities are currently at Oak Ridge National Laboratory (ORNL) and until recently at the Idaho National Laboratory (INL). At the beginning of Fiscal Year 2006, EM became responsible for disposition of over 1000 containers (~ 450 kg) of surplus uranium-233 stored in Building 3019 at the ORNL. This material will be downblended with depleted uranium to remove safeguards and criticality concerns and the downblended material will be disposed. The Uranium-233 Stabilization and Building 3019 Complex Shutdown project will modify Building 3019 to downblend the material. An Environmental Assessment for the project was issued in March 2007."

CNSC discloses Canadian inventories and use of depleted uranium
Historical Canadian DU Inventory:
About 1,500 metric tons of DU in different forms, such as oxides (DUO2 and DU3O8) and metal blended with other waste products, are stored at Cameco's Port Hope Conversion Facility.
Currently, Cameco imports DU powder (DU3O8) from various countries to produce depleted nuclear fuel for pressurized heavy water reactors at its Port Hope facilities.
Cameco's Port Hope conversion facility processes DU powder, which is then sent to its fuel fabrication plant, also in Port Hope, where the powder is manufactured into bundles.
Depleted nuclear fuel is used to help control reactivity when the reactor is started.
The waste produced from this process is currently stored on site.
DU metal is not currently produced in Canada. Existing DU metal inventories were mostly produced before the 1990's by Cameco Corporation.
DU metal is also found in manufactured equipment and waste. About 400 metric tons of DU metal are currently stored in Canada.
The total amount of DU - in its powder or metal form - imported into Canada between January 1, 2004, and December 31, 2008, was 161,318 kg. Almost all of that (97%) was received by Cameco Corporation as DU powder.
The remaining 3% was DU metal. Most of it came from the international customers of MDS Nordion, who returned shielding medical equipment containing DU metal.
