The German paper Süddeutsche Zeitung says prosecutors are probing Germany's third biggest power utility, EnBW, for allegedly transferring funds to Switzerland, possibly to obtain nuclear fuel rods and gas from Russia.
The German power utility Energie Baden-Württemberg (EnBW) had secretly channeled about 280 million euros ($386 million) to "slush fund" accounts in Switzerland and then to a Russian lobbyist and his Swiss firms, the German daily newspaper Süddeutsche Zeitung (SZ) claimed on Monday (Oct. 28).
But, after getting "cold feet," EnBW later applied to retrospectively revise its tax returns for the period 2000-2007 and paid some 60 million euros to Germany's revenue collection service, said the daily, which is widely read in Germany.

Russia and Ukraine are discussing the creating of a joint venture for the conversion and enrichment of uranium on Russian soil, the head of Russia's state nuclear power corporation Rosatom, Sergei Kirienko, has told the press.
The two countries already have a JV in Ukraine for the fabrication of nuclear fuel, in which Ukraine holds the controlling stake. If the enrichment JV in Russia is set up, Russia will have control, Kirienko said.
Ukrainian Energy and Coal Industry Minister Yuriy Boiko has confirmed that the countries are interested in integration in the field of converting and enriching uranium, as Ukraine has undertaken not to perform such operations at home.

Decommissioning of Seversk conversion plant used for HEU downblending now completed
At the sublimation plant of the Siberian Chemical Combine (SCHK JSC is part of the TVEL Fuel Company of Rosatom), decommissioning of a nuclear and radiation hazardous facility, a highly enriched uranium oxide processing plant (M2079), was completed.
The M2079 installation was created at the SCHK JSC sublimation plant in 1996 as part of the Russian-American agreement on nuclear disarmament, which involves the conversion of highly enriched uranium (HEU) into low-enriched energy uranium (LEU). Uranium hexafluoride was obtained at the facility by fluorination of highly enriched uranium oxides. On October 1, 2013, the M2079 installation was stopped. Nuclear materials were removed from the plant's technological equipment, and the equipment was transferred to a nuclear-safe state.
During 2018 - 2019, decommissioning was carried out: decontamination of premises, building structures and engineering systems was carried out, technological equipment, pipelines and engineering systems formed by radioactive waste were dismantled, the eligibility criteria were transferred, and transferred to the burial place of FSUE NO RAO.
A commission audit carried out by the State Atomic Energy Corporation Rosatom and TVEL JSC in March 2020 confirmed that the decommissioning of the M2079 installation at the SCHK JSC sublimation plant was completed in full and in accordance with the project.

Transport company TLI pays US$ 2 million to settle charges over bribes in connection with former shipments of downblended HEU from Russia to the U.S.
A Maryland-based company has agreed to pay $2 million to settle charges that it bribed a Russian official to win contracts to ship uranium to the United States, U.S. authorities said on Tuesday (Mar. 13).
Transport Logistics International admitted to bribing the Russian official with more than $1.7 million over the course of a decade, through a maze of shell companies and accounts in Latvia, Cyprus and Switzerland, according to Maryland federal court papers made public on Tuesday.
For decades, Washington and Moscow had an agreement that converted uranium from Russia's nuclear stockpiles to civilian grade fuel, which was shipped to the United States for use in civilian power plants.
To win contracts to ship the Russian uranium, from 2004 to 2014, TLI executives bribed Vadim Mikerin, a former director of Russia's state-owned nuclear enterprise Rosatom.

Russia sends last shipment of downblended HEU for use in U.S. reactors
A 20-year-old deal that has powered American homes while reducing the risk of Russian nuclear material falling into the wrong hands approached its end on Thursday (Nov. 14) when the final shipment of uranium left St Petersburg for Baltimore.
Under the 1993 HEU Purchase Agreement, Russia downblended 500 metric tons of highly enriched uranium (HEU) from nuclear weapons into low-enriched uranium and sent it to the United States, where it was made into fuel for nuclear power plants.

Companies Amend Deal for Uranium from Dismantled Russian Nuclear Weapons
Cameco, COGEMA and RWE NUKEM (collectively the western companies) announced they have signed an amendment with Techsnabexport (Tenex) that ensures the continued operation of the UF6 Feed Component Implementing Contract (HEU Contract) to the end of its term in 2013. The amendment provides for, amongst other things, that the western companies will forego a portion of their future options on non-quota HEU-derived uranium (i.e. quantities for consumption outside the US) to ensure there is sufficient material in Russia for blending down the weapons grade HEU to commercially usable low enriched uranium (LEU). This change was needed in light of Russia's rising requirements for uranium to fuel their expanding nuclear plant construction program within Russia and abroad. The amendment to the HEU Contract is subject to approval by the US and Russian governments.

US, Russia, agree on flexible pricing terms for Megatons to Megawatts program
The U.S. and Russian governments have approved implementation of new, flexible market-based pricing terms for the remaining 12 years of the historic Megatons to Megawatts national security program. The new flexible pricing terms will go into effect in January 2003.
The terms of the amendment between USEC and Tenex, the Russian executive agent, include a commitment through 2013 to purchase at least 5.5 million SWU annually, which is derived from approximately 30 metric tons of highly enriched uranium (HEU), resulting in the purchase of a total of 500 metric tons.

TVEL set to ship fuel pellets to India
India's Nuclear Fuel Complex (NFC) has signed a protocol of acceptance with TVEL for the first 30 tonnes of uranium dioxide pellets to fuel Indian nuclear power reactors.
The protocol for the shipment of the first batch of nuclear fuel pellets to be sent to India was signed after a delegation from NFC visited TVEL's Mashinostroitelny Zavod (Elemash) plant in Elektrostal near Moscow, Russia.
TVEL and India's Department of Atomic Energy signed a long-term fuel pellet supply contract worth over $700 million in February. Under the contract, TVEL will supply uranium dioxide pellets to Nuclear Power Corp of India Ltd (NPCIL) for several years to ensure fuel supply to the Tarapur plant in Maharashtra state.
TVEL was the first company to have signed such a contract since the lifting of the Nuclear Suppliers Group 's (NSG's) restrictions on India in September 2008. The first delivery of pellets to India is scheduled for the spring of 2009.

Japan to contract Russia for enrichment of recycled uranium
The Japanese government and Japan's major electric power companies have entered the final stage of negotiations with Russia for consigning the enrichment of uranium to Atomenergoprom, or Atomprom, which is to be established as Russia's state-run monopoly for the nuclear energy industry, according to sources close to the deal.
The Japanese side plans to initially consign the enrichment of uranium that was recovered from spent fuel rods and has been stored in Britain.
Though electric power companies had consigned the recovery of uranium from spent fuel to firms in Britain and France, enrichment of the recovered uranium has not progressed partly because of high costs.
The amount of recovered uranium deposited by Japan with the two countries has ballooned to 6,400 tons.
In the future, the Japanese side plans to consign to Russia the enrichment of natural uranium produced in mines to which Japan has obtained the rights in Russia and Kazakhstan.
The Japanese and Russian governments aim to reach a basic agreement over the deal at a summit level meeting by the summer, and will also negotiate the signing of a bilateral nonproliferation accord to prevent nuclear material from getting into third parties' hands, which is essential to consigning the works, the sources said.

Russian uranium (hexafluoride) production to be concentrated in Seversk (Tomsk region)
All the production of uranium in Russia will be concentrated in the Siberian town of Seversk by 2016, Oleg Bekmemetyev, a deputy director general of the Chepetsk Mechanical Plant (CMZ) told reporters Friday (Jan. 25).
"There are three facilities producing uranium in Russia," he said. "There'll be a single one and it'll be located in Seversk in Siberia. A project has been drafted for concentrating the entire production capability there."
At present, uranium is carried from the Far East to Glazov in Udmurtia, a region located to the West of the Urals, as well as to Angarsk in the Irkutsk region and to Seversk in the Tomsk region in central Siberia, and this pattern is inefficient in terms of logistics.
"It's much easier to bring uranium to Seversk, to dress it there and to supply it to the factories producing nuclear fuel," Bekmemetyev said.

Seversk enrichment plant waste disposal scheme puts drinking water at risk
As the Seversk plant (re-)enriches uranium also for Swiss utilities, Swiss TV investigated the environmental situation at this plant. In addition to environmental contamination (in particular by plutonium) resulting from former military production at the site, the waste disposal scheme of current operations caught the attention of the journalists: the liquid wastes from the plant are disposed of by underground injection at depths between 250 and 400 metres. According to Prof Leonid Richwanov of Tomsk University, this practice endangers the municipal water supply of Seversk, once the disposed liquids reach the groundwater used for potable water abstraction.

Since the mid-1990s, France sends 108 t of recycled uranium per year from the La Hague reprocessing plant to Seversk for (re-)enrichment. The material is sent to St Petersburg by ship and is further transported to Siberia by train. The depleted uranium generated by the (re-)enrichment process becomes the property of Tenex and is stored in containers in open yards near the enrichment plant.
(Libération Oct. 12, 2009)
The recycled uranium is exported for enrichment, since France's only enrichment plant - the gaseous diffusion plan of Tricastin - does not dispose of a special circuit for the enrichment of recycled uranium (which must be kept separate from natural uranium for its contents of unwanted isotopes).
The article mistakenly uses the term depleted uranium in several instances when referring to the recycled uranium, while in fact this still is slightly higher enriched than natural uranium. Further, there is no mention of the conversion process required prior to enrichment of the recycled uranium. Since there is no conversion plant in Western Europe capable of converting recycled uranium to UF6, this process presumably also takes place in Russia.

Presidential Council on Human Rights concerned about storage of depleted uranium hexafluoride in open air at Angarsk
The Presidential Council on Human Rights (HRC) is concerned about radiation safety at the Angarsk Electrolysis Chemical Plant.
"The problem of ensuring safety during long-term container storage in open areas of the Angarsk Electrolysis Chemical Combine of depleted uranium hexafluoride (hereinafter referred to as DUHF), a by-product of uranium enrichment, remains relevant," the council's recommendations based on the results of the visiting meeting in Irkutsk say.
They note that "DUHF is toxic and radioactive, under certain conditions it is volatile, its storage in open areas of the Angarsk electrolysis chemical plant is particularly dangerous due to the significant volumes of stored material (taking into account the total volume of 1 million tonnes of DUHF, stored in four nuclear fuel cycle enterprises, the volume of DUHF at the sites of the Angarsk electrolysis chemical plant can be estimated at hundreds of thousands of tonnes)."
According to the Council, satellite imagery for October 28, 2018 and February 10, 2019 shows that containers continue to be stored in open areas and do not become smaller. Rostekhnadzor believes that the containers with DUHF are stored in open areas under the risk of depressurization - due to corrosion of containers and the risk of aircraft crashes, since the chemical plant site is several tens of kilometers from Irkutsk airport.
The HRC noted that the depressurization of containers with DUHF entails environmental risks, as well as the risk of radiation pollution. So, when exposed to moisture from the air, depleted uranium hexafluoride forms hydrofluoric acid (hazard class II), the vapors of which, when MPC is exceeded, strongly irritate the upper respiratory tract and mucous membranes, can cause acute and chronic poisoning, changes in the digestive and respiratory organs, and cardiovascular system, as well as changes in the composition of the blood.
The capacities available in Russia for converting (reconverting) DUHF into a chemically less active state (oxide form) have not yet solved the problem, since they cannot cope with large volumes of DUHF. [...]
The HRC recommended the EMERCOM of Russia and the Angarsk administration to publish plans for protecting the population in the event of container depressurization, and Rosatome, TVEL JSC to Rostekhnadzor to prepare a report on the storage conditions of DUHF at industrial enterprises, to compile a review of the DUHF conversion technologies, and to develop a roadmap for speedy transfer of DUHF to a less dangerous form.

After the sublimation plant [that changes the physical state of the UF6 feed from solid to gaseous] stopped operation, the enrichment plant was fed with depleted uranium (tails) left from former enrichment work. The tails are re-enriched to natural-uranium equivalent.

Today the plant operates in the so-called "mine operation", being engaged in processing of depleted uranium hexafluoride, of which enough reserves are available for decades of trouble-free operation of the enrichment plant. The secondary waste uranium hexafluoride is sent to the Zelenogorsk Electrochemical Plant (TVEL Fuel Company) for further processing. Thus, the plant is freeing its area of uranium-bearing materials.

Properties and fate of radioactive waste to be removed from storage site at Angarsk uranium enrichment plant unclear - hearing reveals; no explanation for presence of artificial nuclides given
The Russian uranium enrichment enterprise Angarsk Electrolysis Chemical Combine (AECC) admitted at a public hearing in early December that radioactive waste containing uranium, transuranic elements, and uranium fission products are in storage at its "Site 310." But with no detailed plan about what to do next with the waste, the facility and the waste's future remains under debate.
The public hearing was convened in Angarsk, Irkutsk Region in Southwestern Siberia, on December 5 to discuss the Environmental Impact Assessment report for the proposed project of decommissioning the storage facilities of Site 310 – which will require relocating the waste contained inside them, with, so far, no specific address available for where send it.
The Environmental Impact Assessment report was thus sent back for further review.
The AECC's Derzhavin gave the following description of the waste:
"Site 310 holds process waste in the solid physical state. According to record-keeping data, the total mass of the waste is 1,910.97 tons. The total volume is 1,942.5 cubic meters. As regards the chemical composition, the waste is presented as a mix of fluorides, oxides, and carbonates of natural isotopes of uranium. Besides uranium isotopes, the radioactivity of the waste is due to the presence of transuranic and fission elements. The average uranium content in the process waste does not exceed 1 percent."
No clarity was provided to the question of which transuranium elements exactly are present in the waste. As transuranium elements are not found in natural uranium, it stands to reason that the AECC's operations involved reprocessed uranium, possibly of foreign origin. The presence of transuranic elements such as plutonium, neptunium, or americium, would make the waste that much more dangerous and difficult to handle.
Besides, the information presented at the hearing is at odds with the combine's environmental safety report, which states that "radioactive waste is generated as a result of processing raw material of natural origin, composed only of natural uranium radionuclides."

Activist demands deconversion of depleted uranium of European origin stored in Angarsk
Russian journalist and anti-nuclear activist Swetlana Slobina demands the deconversion of the depleted uranium hexafluoride of European origin currently stored outside the Angarsk enrichment plant. The deconversion to an oxide form reduces the chemical hazards of the material. Slobina calls upon the European suppliers of the material to assist with making the deconversion possible.
Last year, the Angarsk enrichment company had announced that the hazards resulting from deteriorating containers had been eleminated by transfering the material to new containers.

Demonstration in Angarsk against uranium enrichment and storage of Urenco's depleted uranium
In the first anti-nuclear demonstration ever held in Angarsk, 150 people protested on July 3, 2011, against environmental and social problems connected to the Angarsk enrichment plant and the storage of Urenco's depleted uranium hexafluoride (tails) in the city. The demonstration was held on the same day as a demonstration at Gronau, Germany, where some of the tails originated.

Angarsk enrichment plant wants its premises excised from city territory to avoid legal conflict over depleted uranium hexafluoride (tails) storage
The uranium enrichment enterprise Angarsk Electrolysis Chemical Combine (AECC), founded in 1954, is located right on the outskirts of Angarsk, a city of 241,000 in Russia's Irkutsk Region in Southeast Siberia. In fact, AECC's production-related sites - including open-air yards housing containers with highly toxic radioactive waste - are within city limits.
That highly toxic waste is depleted uranium hexafluoride, also called uranium tails - a by-product generated when enriching uranium for the production of nuclear reactor fuel. This waste is stored on the premises of AECC - and so, on the territory of the city of Angarsk. Environmentalists say it is toxic enough that a leak occurring through loss of sealing in a container may result in deaths as far as 32 kilometres away.
According to the legislation currently in force, a radioactive materials storage facility must be part of a unified state registry of sites of storage or disposal of hazardous materials, including radioactive waste. But the law also prohibits operation of such sites within city limits - and that is exactly the case with AECC.
The solution suggested by the plant was to change virtually nothing, and spend nothing on any works associated with the storage facility - but simply move AECC's premises out of the city boundaries on paper. The plant would physically stay where it is - but would not be legally part of the city's territory.
A public hearing was held on December 28, 2009, where the issue of granting AECC the formal status of an enterprise operating out of city limits - without it changing its physical location - was discussed. No decisions have been taken yet on the proposal.

New UO2 powder production line commissioned at Novosibirsk nuclear fuel plant
The Novosibirsk Chemical Concentrates Plant - part of Russia's TVEL - has commissioned a new production line for uranium dioxide powder. The new line uses a high-temperature 'dry' process, rather than 'wet' extraction technology currently used at the plant.
The new process uses high-temperature pyrohydrolysis to produce uranium dioxide (UO2) powder that will be formed into pellets and encased in alloy tubes to form fuel rods. Novosibirsk Chemical Concentrates Plant (NCCP) held a ceremony yesterday to mark the commissioning of its new line, attended by Yuri Olenin, president of TVEL, and Victor Tolokonsky, governor of the Novosibirsk region.
The construction schedule for the pilot production line, which has a capacity of 400 tonnes per year, was approved by TVEL executives in August 2007. In 2010, all construction work was completed, equipment installed and the site was officially handed over for commissioning. Investment in the project totalled over 800 million roubles ($26 million).
According to TVEL, using the dry conversion process rather than the wet process will substantially reduce the cost of the UO2 powder produced. This is primarily due to maximum automation of the dry conversion process. In addition, the production capacity of the new line is three times that of several existing wet process production lines at the Novosibirsk plant.
TVEL also noted that new production line would have the advantage of reducing the amount of nuclear material feed placed in the process equipment, as well as cutting the amount of work in progress. The line should reduce the impact on the environment and minimize the plant's generation of hazardous waste.

Factories linked to Novosibirsk nuclear fuel plant polluting major river in Siberia - prosecutors
About ten industrial facilities linked to a major nuclear-fuel plant in western Siberia are polluting the Ob River, local prosecutors said on March 16, 2006.
The factories are all linked to a waste-treatment plant owned by the Novosibirsk Chemical Concentrates Plant (NCCP), a key part of Russia's nuclear-fuel production industry.
Local water-administration authorities refused to renew the plant's drainage license in October 2005, saying its treatment systems were inefficient and that it failed to report the precise volume of waste being dumped into the river and the waste's hazardous content.
"We set a threshold for chemical concentration in waste when issuing licenses to protect the environment," a local official said. "How we are supposed to issue a license if we do not even know the amount of waste dumped in the river?"
The official said that the NCCP should install efficient purification facilities before a license can be issued. NCCP officials, however, said the plant would not apply for a new license, as it no longer sent waste through the treatment plant, which is now used only by other enterprises.
A local court fined NCCP 25,000 rubles ($898) and ordered the suspension of waste disposal through the plant until a new license was granted.
Ecology experts are carrying out the evaluation of environmental damages caused by waste dumping into the Ob River, the world's fourth longest at about 2,300 miles, which flows from Russia's mountainous Altai Region through Novosibirsk and empties into the Arctic Ocean.
A controlling stake in NCCP is held by TVEL Corp. , a 100% state-owned joint-stock company that produces nuclear fuel for Russia's nuclear power plants.

Zelenogorsk MOX fuel plant to increase MOX fuel production for fast breeder reactor BN-800:
Russia's Zheleznogorsk Mining and Chemical Combine is ramping up production of mixed uranium and plutonium oxide fuel, or MOX, in a push toward creating a closed nuclear fuel cycle, with the country's BN-800 fast neutron reactor as its centerpiece.
Zheleznogorsk's general director, Pyotr Gavrilov, said in a side interview last week at the World Nuclear Association's annual symposium that production of MOX by the MCC is expected to jump from 20 fuel assemblies this year to 400 by 2017. The hike requires regulatory approval, which Gavrilov said he expects, to get.
