General

Reuse remains NDA's preferred option for the disposition of UK's plutonium stocks

"In summary, this work has resulted in NDA concluding that reuse remains the preferred option and, based on the information provided and against our definitions, there are three credible reuse options: - reuse as MOX in light water reactors, reuse in CANDU EC6 reactors and reuse in PRISM fast reactors. We note all the technologies being considered have pros and cons and that no 'perfect' solution exists. It may be that a multi-track approach offers best value for money.
Currently, we believe there is insufficient understanding of the options to confidently move into implementation and consider that significant further work must be undertaken, focusing on technical and commercial risks and uncertainties, to enable DECC and UK Government to ultimately select and subsequently implement its preferred reuse option."

UK Nuclear Decommmissioning Authority's management strategy for "materials" / wastes containing uranium (in particular depleted uranium): wait and see

The UK Nuclear Decommmissioning Authority (NDA) has published a summary of Credible Options for the management of uranics on the NDA estate. The NDA owns a range of materials containing uranium (termed uranics) arising from historic or current nuclear fuel cycle operations. The bulk of the material is depleted uranium, including approx. 21,500 teU in uranium hexafluoride tails (UF6), and 26,000 teU in Magnox Depleted Uranium (UO3).

Britain eyes Japanese participation in plans to reuse plutonium stocks

Britain is likely to convert plutonium stocks into nuclear fuel and will be seeking Japanese involvement in the project, according to government officials. The government's preferred option is to turn the stockpile into mixed uranium and plutonium oxide nuclear fuel (MOX) to power civil reactors.
Britain stores around 112 tons of plutonium, of which 11.6 tons belong to Japanese firms as a result of reprocessing nuclear fuel at the Sellafield complex in Cumbria, northwest Britain. Officials are now studying the plan to ensure it is affordable, deliverable, offers value for money and can be implemented safely. The government is expected to make a final decision in 2015 -- with the facility due to come onstream by 2024 -- and as part of the consultation will be sounding out Japanese utility companies that hold plutonium at Sellafield.
If Japanese companies do not wish to participate in the project, which would involve the construction of a new MOX plant, Britain may consider taking ownership of their plutonium, subject to commercial terms and international agreements. Bill Hamilton, head of stakeholder communications at the Nuclear Decommissioning Authority or NDA, said commitments from Japanese utilities are "important" but not "critical" to the project getting the green light. Estimated costs are 3 billion pounds ($4.7 billion). (Mainichi Daily News Feb. 29, 2011)

NDA seeking proposals for alternatives to re-use of plutonium as MOX fuel

The Nuclear Decommissioning Authority (NDA) is seeking proposals on potential alternative approaches for managing the UK's plutonium stocks alongside providing support to the Government as it progresses its preferred policy of converting the material into Mixed Oxide fuel (MOX) for reactors.
Expressions of interest must be received by 31 March 2012.

UK government starts consultation on management of plutonium stocks, prefers reuse in MOX fuel, implying construction of new MOX fuel plant

On Feb. 7, 2011, the UK Department of Energy and Climate Change launched a public consultation on the management of the country's plutonium stocks.
The government's "preliminary policy view" is that the use in MOX fuel is the preferred option. This would require the construction of a new MOX fuel plant, as the existing plant is almost dysfunctional.

UK's separated plutonium stockpile poses severe risks warns Royal Society

The potential consequences of a major security breach or accident involving the UK's stockpile of separated plutonium are so severe that the Government should urgently develop and implement a strategy for its long term use or disposal warns a report published by the Royal Society the UK national academy of science on 21 September 2007.
According to Strategy options for the UK's separated plutonium the UK's civil stockpile of separated plutonium is now over 100 tonnes and has almost doubled in the last 10 years. The UK's stockpile is largely the by-product of commercial reprocessing of spent fuel from UK power plants.

Study analyses economics of management options for UK uranium and plutonium stockpile

The UK Nuclear Decommissioning Authority released a study analysing the economics of various management options for the UK uranium and plutonium stockpile. The stockpile comprises: The management options analysed were disposal as waste, 300-year storage with subsequent disposal as waste, and use for production of nuclear fuel. In the latter case, the plutonium could be processed into 1,500 t HM of PWR fuel, and the uranium could be processed into 500 - 2,500 t U of PWR fuel, depending on the future price of uranium. The total would be sufficient to supply 1.5 to 3 reactors of 1000 MWe capacity over a 60 year lifetime. The cost for these options were determined as follows: The study concludes:

Nuclear Decommissioning Authority transfers its Capenhurst site to Urenco

On 30 November 2012, the Nuclear Decommissioning Authority announced that it has completed the transfer of its Capenhurst site, in Cheshire, continuing an asset disposal programme which has now brought in well over GBP 1 billion for the UK taxpayer. Under the deal, Capenhurst Nuclear Services (CNS), a URENCO Group company, will take ownership of the land, combining it with an adjacent site it already owns to create one nuclear licensed site.

Uranium spill found at Sellafield Ltd Capenhurst site

Sellafield Limited - Capenhurst Works - 28 February 2012: During planned site decommissioning operations, a quantity of historical uranium contaminated water and sludge was found in a radiologically controlled area that was recently undergoing decommissioning clean up operations.  The spillage was contained within concrete service channels, which were underneath steel plate covers. Detailed analysis of the water and sludge was promptly conducted, in order to confirm the actions required to safely remove the material. There has been no injury or damage, no significant release of radioactive material, there was no potential for any off-site hazard and the public were not affected. (HSE Office for Nuclear Regulation: Statement of nuclear incidents at nuclear installations - Q1 2012)

Nuclear Decommissioning Authority, Urenco sign agreement on transfer of NDA's Capenhurst site to Urenco

"An agreement has today been signed confirming the future transfer of the NDA-owned site at Capenhurst to URENCO, which occupies the adjacent nuclear-licensed site in Cheshire. The transition will result in the disposal of some NDA-owned land on and adjacent to the site, enabling the Capenhurst site to transition to single licensee status. Existing decommissioning and storage operations currently undertaken by Sellafield Ltd will transfer to URENCO.
NDA and URENCO have also signed an agreement for the processing of government-owned by-product/legacy material from uranium enrichment (known as "Tails") through URENCO's Tails Management Facility. Most of this material is currently stored at the NDA site at Capenhurst. It is anticipated that this agreement will reduce NDA's net liabilities for managing and clearing the site while also paving the way for URENCO to invest in new facilities as required in order to meet future customer demand." (NDA Dec. 1, 2011)

Nuclear Decommissioning Authority may transfer Capenhurst site to Urenco

The UK's Nuclear Decommissioning Authority (NDA) is considering transferring management and operation of its Capenhurst operations to Urenco , which already owns and operates a centrifuge uranium enrichment plant on part of the site.
The Capenhurst site is currently split into two parts. One part - a former diffusion uranium enrichment plant that shut down in 1982 - is owned by the NDA and operated by contractor Sellafield Ltd. While most of the plant has now been decommissioned, uranic material (primarily depleted uranium and uranium hexafluoride) is expected to be stored on the site until 2120. The other part of the Capenhurst site comprises Urenco's operating enrichment plant.
The NDA and Urenco have announced the signing of a set of non-binding commercial principles to support a potential transfer of the NDA portion of the site to Urenco. Under the proposed transaction, NDA-owned land and operations would be transferred to Urenco under a long lease and services contract. (World Nuclear News Oct. 29, 2010)

Depleted uranium hexafluoride cylinder found leaking at Sellafield Ltd Capenhurst site

Sellafield Limited - Capenhurst Works reported on 24 July 2009  the  leakage of radioactive liquor from one of the uranium hexafluoride ("Hex Tails") cylinders, currently stored inside a building. The leak was discovered during routine plant surveillance. The hole in the leaking cylinder was promptly sealed by the site fire brigade. There was no significant personal radiation exposure or contamination and no release to the environment of airborne radioactivity.

BNG Capenhurst site nears end of its clean-up

Capenhurst's nuclear clean-up team has reached a key milestone as it completed the UK nuclear industry's biggest demolition project. The site in south Wirral housed the UK's first uranium enrichment plant and is nearing the completion of its decommissioning programme. It is scheduled to become the first UK nuclear site to complete its clean-up programme in 2009. The decommissioning site is owned by the Nuclear Decommissioning Authority (NDA) and managed and operated by clean-up contractor Sellafield Ltd. The enrichment plant, which ceased operations in 1982, has been demolished clearing 32,000 m2 - equivalent to four football pitches - of valuable space for potential re-use. In addition, 94% of the clean materials from the building have been recycled. (The Liverpool Daily Post Feb. 25, 2008)

EURODIF enrichment plant, Tricastin (Drôme)

Violation of safety rules at decommissioning EURODIF enrichment plant

On Feb. 17, 2017, Areva announced that it had transfered the superversion of the safety alarms of the Eurodif plant to the central control room of the Tricastin site at the end 2016 without proper authorization.
On Feb. 20, 2017, the Nuclear Safety Authority ASN, which had detected the violation during an inspection on Feb. 17, 2017, rated this incident Level 1 on the INES scale.

Iran finds way to get Eurodif, Rössing dividend despite sanctions, report

Iran has found a way to receive arrear dividends from European consortium Eurodif and the Namibia-based Rössing Uranium Ltd. which had been blocked due the country's nuclear program, ISNA reported on Wednesday (Jan. 25).
Iran's dividend in Eurodif has not been paid since 2006, however, the implementation of the nuclear deal in January 2016 paved the way for Iran to receive its share which is estimated to be around 54 million euros.
Meanwhile, Iran had a 15-percent share in Rössing in the 1970s. But, the country has not been successful in receiving its dividend yet. (Teheran Times Jan. 25, 2017)

Failure to perform recurring function tests of radiation monitoring equipment at decommissioning Eurodif gaseous diffusion enrichment plant

During an inspection held on Oct. 22, 2015, the Nuclear Safety Authority ASN found that certain radiation monitoring devices had not been submitted to recurring function tests. The event was rated level 1 on the INES scale. (ASN Nov. 2, 2015)

Violation of criticality rules at Areva Tricastin site

During reconditioning of waste containers held at the Areva Tricastin site since 1996, excessive contents of U-235 was found in two containers. The event was rated level 1 on the INES scale. (ASN Oct. 16, 2015)

"Rinsing" phase of decommissioning of Eurodif gaseous diffusion enrichment plant completed

Areva celebrated today at the Tricastin site in France the completion of the "rinsing" phase of the former gaseous diffusion enrichment facility, Eurodif, as part of its dismantling. This step has significantly reduced the quantity of nuclear and chemical materials present within the facility to ensure the safety of the subsequent operations as part of its deconstruction. The next step will be the completion of the clean-up of the gaseous diffusion equipment in 2016. (Areva Oct. 15, 2015)

Violation of criticality rules at decommissioning EURODIF enrichment plant

Ashes resulting from the burning of oil containing traces of uranium were collected in bins with a capacity of 200 litres instead of the permitted 30 litres. Areva proposes to rate the event level 1 on the INES scale. (Areva Sep. 15, 2015)

Anomaly with chlorine trifluoride at decommissioning EURODIF enrichment plant

On Sep. 24, 2014, a pressure rise occured in a crystallizer used to remove uranium hexafluoride from the cascade with the help of chlorine trifluoride (ClF3). The event was rated level 1 on the INES scale. (ASN Sep. 29, 2014)

Violation of criticality rules at decommissioning EURODIF enrichment plant

On July 29, 2014, humid air was incidentally introduced into a group of gaseous diffusion chambers being decommissioned. This could have presented a criticality risk and the risk of formation of hydrofluoric acid. The event was rated level 1 on the INES scale. (ASN Aug. 4, 2014)

Areva wants to use decommissioning funds of Eurodif enrichment plant for construction of nuclear power plant in the UK

Areva is in talks with the French government to release some funds set aside for dismantling its nuclear installations in France to help the company finance a new British nuclear reactor, French newspaper Les Echos reported.
State-owned Areva is taking a 10 percent stake in the consortium that will build the nuclear power plant at Hinkley Point in southwest Britain. Areva wants to ensure the British nuclear project will not impact its debt, which is rated BBB- by Standard and Poors, one notch above "junk" territory. It will need 500 million pounds to finance its share of Hinkley Point, according to one source quoted by the newspaper.
A 2012 French parliamentary report showed it could cost Areva up to 7.1 billion euros to dismantle its nuclear installations, which include the La Hague nuclear fuel reprocessing plant and Eurodif, a uranium enrichment factory. (Reuters Dec. 16, 2013)

Uranium spill at Areva's effluent treatment plant in Tricastin

On Sep. 11, 2013, during the repackaging of a drum containing potassium diuranate, 30 kg of uranium were spilled in a room in the SOCATRI facilities. The event was rated level 1 on the INES scale. (ASN Nov. 15, 2013)
(Areva subsidiary Société auxiliaire du Tricastin (SOCATRI) operates an effluent treatment plant mainly for the Eurodif enrichment plant.)

Anomaly with chlorine trifluoride at decommissioning EURODIF enrichment plant

On Sep. 30, 2013, Eurodif declared an event involving chlorine trifluoride (ClF3). This corrosive and toxic substance is used to remove residual solid uranium hexafluoride (UF6) from the diffusion chambers of the enrichment plant. On Sep. 26, 2013, due to disregard of instructions, gazeous ClF3 inadvertently condensed to liquid form inside a diffusion chamber. The event was rated level 1 on the INES scale. (ASN Oct. 4, 2013)

Recycling rather than disposal of the contaminated steel resulting from dismantling of the Eurodif enrichment plant?

At the June 21, 2012, meeting of the Commission Locale d'Information auprès des Grands Équipements Énergétiques du Tricastin (CLIGEET), the representatives of the trade unions made the proposal that the 150,000 t of contaminated steel that will result from the dismantling of the Eurodif enrichment plant should not be disposed of, but cleaned and recycled.
Areva's current plan is to dispose of them in ANDRA's Centre de l'Aube underground nuclear waste disposal site, located at a distance of 600 km.

Anomaly with depleted UF6 cylinder at Eurodif enrichment plant

On July 1, 2012, an anomaly was detected while transfering depleted UF6 from a thin-walled storage cylinder to a transport cylinder: as the cylinder was heated to transform the contents to the gaseous form, the cylinder's mass showed an unexpected development, probably indicating that the contents rather had been transformed to the liquid form. The liquid UF6 is very volatile and the transformation to the liquid state involves a strong volume expansion. The process was aborted immediately. The event was rated level 1 on the INES scale.

Mysterious particles found in soil near the Hanau nuclear fuel plants

Spherical radioactive particles have been found in soil samples from the surroundings of the Hanau nuclear fuel plants, according to the TV program "Report Mainz". The particles with a diameter of approx. 1 mm were found at a depth of 15 cm and are reported to contain plutonium, enriched uranium, curium, and americium, among others. It is speculated that the particles stem from the production of fuel for the former high-temperature reactor of the Jülich nuclear research center. (AP May 5, 2002)
After the program was aired, "Report Mainz" admitted that the statements about the composition of the particles only referred to similar ones found near the GKSS nuclear research center in Geesthacht in the northern state of Schleswig-Holstein. The Hanau particles only looked similar to those from Geesthacht under the electron microscope. (Main Echo May 10, 2002)
Meanwhile it seems more likely that the particles are ordinary slag from coal-fired power plants or blast furnaces. Such slag often was used in the 1970s and 1980s to stabilize the subsoil in development areas. (Frankfurter Rundschau May 16, 2002)
According to an analysis done by the Marburg university, the particles do not contain nuclear fuel and are not more radioactive than normal soil. (Main Echo May 17, 2002)
On June 26, 2002, the Hanau public prosecutor's office suspended proceedings in this case. The radiation in the samples were at or below natural background levels and presented no hazard to the public. (Netzeitung June 26, 2002)
On Sep. 13, 2002, the Hesse State Ministry of Environment released an investigation report completely dismissing all claims made related to the particles. However, in 5 out of 34 soil samples, a slight enrichment (1.3 - 1.7%) of uranium-235 was found. Though the report has no explanation for this finding, it is of no radiological significance, since the average uranium-238 concentrations are less than 20 Bq/kg. This corresponds to a uranium concentration in soil of 1.6 ppm - a value typical for Germany and less than the average 3 ppm found in the earth's crust.

Decommissioning of Nukem Hanau nuclear fuel plant approved

On Oct. 25, 2000, the Hesse State Government approved the decommissioning of the Nukem nuclear fuel production plant at Hanau. The plant is shut down since 1988. 28,000 tonnes of slightly contaminated rubble and soil are to be disposed of in the former underground rocksalt mine of Kochendorf near Heilbronn (Baden-Württemberg). 7000 casks of radioactive waste (containing 350 kg of residual uranium) are to be brought to a Nuclear Cargo und Service (NCS) storage site in Hanau for intermediate storage. (Frankfurter Rundschau Oct. 26, 2000)
The Hesse State Ministry of Environment has approved the transport of 7500 tonnes of low level radioactive waste from the decommissioning of the Hanau fuel plant for disposal in the Kochendorf rocksalt mine.

Siemens MOX fuel production plant (old), Hanau (closed)

Hanau residual plutonium to be processed by COGEMA into MOX fuel

The unused plutonium-containing nuclear fuel still stored in Hanau will be processed in to MOX fuel for use in German nuclear power plants.
The plutonium storage bunker at Hanau still contains the unused nuclear fuel manufactured for the abandoned fast breeder reactors at the Karlsruhe nuclear research center and at Kalkar. The material contains up to 35% plutonium. It is now planned to ship the material to France for processing into MOX fuel at La Hague and Marcoule. The MOX fuel produced will then be used in German nuclear power plants owned by RWE Power AG.
This procedure will cost approx. Euro 235 million and will allow for the final decommissioning of the former Hanau MOX fuel plant, where the material is being stored so far.

State approves intermediate storage of Hanau MOX fuel plant decommissioning waste

On June 11, 2002, the Hesse State Minister of Environment approved the construction of an intermediate storage hall for nuclear waste from decommissioning of the Siemens nuclear fuel plant. The hall is licensed for the storage of up to 1200 casks, containing a total of up to 9000 cubic meters of waste. The waste material, mainly contaminated soil and rubble from demolished buildings, may contain a total of up to 95 kgs of plutonium and 9000 kgs of uranium. In the future, the material shall be transfered to the planned Schacht Konrad low-level radioactive waste deposit. (Main Echo June 12, 2002)

Decommissioning of old Siemens Hanau MOX fuel plant approved

On May 30, 2001, the Hesse State Ministry of Environment (HMULF) issued a first part approval for the decommissioning of the old Siemens MOX fuel production plant at Hanau. Siemens now can start the dismantling of the plutonium-contaminated equipment. The resulting radioactive waste will be cemented in barrels. The barrels will be cemented in casks and provisionally stored in a storage building to be built on site by Nuclear Cargo Service (NCS).
The plant used to produce mixed oxide fuel elements from plutonium and uranium. The plant was closed in 1995. Since 1998, the plant operated in a clear out mode, producing more than 6000 storage rods from 642 kgs of plutonium and 13 tonnes of uranium. These rods are scheduled for reprocessing in France.
The complete dismantling of the plant is expected to last until 2005.

Unused Hanau MOX fuel plant equipment to be sold to China?

On December 2, 2003, German Chancellor Schröder made public a request by China to purchase the equipment of Siemens' never operated Hanau MOX fuel plant. Siemens had filed a preliminary request for an export license in February 2003 already. The equipment has already been dismantled and packed in sea containers. It is, however, not clear for what purpose the equipment will be used, since China has no civilian plutonium stocks (as required for MOX fuel production). Therefore, fears are arising that the equipment (or at least components thereof) might be intended for use in China's military nuclear programme - precluding the issuance of an export license.
On April 27, 2004, the speaker of China's state department said that the talks on a purchase of the Hanau plant equipment have been discontinued. (dpa Apr. 27, 2004)

On Feb. 2, 2002, Siemens announced that the dismantling of the never operated Hanau MOX fuel plant will start later the same month. (dpa-afx Feb 3, 2002)

No export of new Hanau MOX fuel plant to Russia

Siemens is no longer offering the new but never operated Hanau MOX fuel plant for export to Russia. Financial commitments made to the company (from the US and France) were only DM 500 million (US$ 234 million), while the export cost is estimated at DM 2 billion (US$ 935 million). Siemens is now trying to sell the plant in parts, otherwise it will be scrapped. The original cost of the plant was DM 1.2 billion (US$ 561 million). It was completed in 1991.

German government not pleased about possible export of new Hanau MOX fuel plant to Russia

The German government sees only little chance to prevent the proposed export of the never operated new Siemens MOX fuel plant at Hanau to Russia. In Russia, the plant would be used to produce MOX fuel from excess weapons' plutonium. But, with the capacity of the plant being higher than Russia's needs, the German government fears a further push for nuclear, while it has just made a decision for a nuclear phase-out in Germany (Frankfurter Rundschau Aug. 28, 2000)
 

Siemens nuclear fuel production plant (former RBU), Hanau (closed)

Complete site of former Siemens nuclear fuel production plant in Hanau released for general use; groundwater restoration continuing

On May 3, 2006, the Hesse State Ministry of Environment released the complete site of the former RBU nuclear fuel plant for general use. The buildings remaining on site can be used without restrictions. The site reclamation goal for groundwater has not been attained yet, however. Further treatment of groundwater is therefore required. (HMULV May 3, 2006)

 

First section of decommissioned former RBU Hanau nuclear fuel plant site released for general use

A first 1000 m2 tract of the 32,000 m2 former RBU nuclear fuel plant in Hanau was released for general use. After demolition of the buildings and replacement of the soil, the tract now is suitable for industrial development and housing. The decommissioning of the whole RBU plant shall be completed by mid-2004. (Frankfurter Allgemeine Zeitung, Aug. 5, 2003)

 

Unexploded World-War-II ordnance discovered during decommissioning of Siemens Hanau nuclear fuel plant

On November 20, 2001, a 50-kilogram bomb was defused at the premises of the former Siemens nuclear fuel plant in Hanau. The bomb had been dropped by the US Air Force in World-War-II. It had not been detected during surveys performed before the construction of the plant. It was found only now during the decommissioning of the plant. (Frankfurter Rundschau Nov. 21, 2001)

 

Former nuclear fuel plant worker sued Siemens for lung fibrosis

A former worker at the Hanau nuclear fuel plant sues Siemens AG for payment of a compensation of DM 3 million (US$ 1.4 million) for having contracted a lung fibrosis during work. Michael Weber used to work in 1971 as a contract worker at the Reaktor-Brennelemente-Gesellschaft (RBG) nuclear fuel production plant in Hanau, Germany. Siemens AG is the legal successor of the owner of the meanwhile closed plant. During an accident, Weber was completely covered with UO2 dust and he inhaled the dust. In 1981, he developed a lung fibrosis, decreasing his lung function by 85% and leaving him permanently disabled since. An expert of nuclear medicine had confirmed that the disease is caused from radiation, and the employers' liability insurance had acknowledged the lung fibrosis as work-related. Siemens dismisses all claims. (Frankfurter Rundschau May 23, 2000)

On May 24, 2000, Weber rejected a proposal for a settlement, made by the judge and accepted by Siemens: Siemens would have paid Weber's proceedings cost of DM 60,000 (US$ 28,000), but would not have acknowledged any liability. In the opinion of the judge, it is very likely that Weber's claims come under the statute of limitations. (Frankfurter Rundschau May 25, 2000)

On July 26, 2000, the Nüremberg Superior Court (Landgericht) dismissed the suit for formal reasons.

On September 4, 2000, Weber lodged an appeal to the Nüremberg Court of Appeal (Oberlandesgericht).

On March 8, 2001, Weber accepted the above settlement, since he was not in the financial position to continue the appeals court case.

Michael Weber died on September 17, 2003.

Kirovo-Chepetsk Chemical Combine (KCChC) conversion plant, Kirov Oblast

The Kirovo-Chepetsk Chemical Combine was built in the 1940s to produce uranium fluorides and it operated until the 1990s. The former uranium fluorides processing building has a volume of 102,000 cubic metres. Tailings and radioactive waste burial sites contain approximately 440,000 tonnes of radioactive waste with a total activity of 3,400 Ci (125.8 TBq). Decommissioning work - including "conservation and protection of radioactive waste storages and tailings", among others - is scheduled for the period 2012 to 2025.
