  • Cameras penetrate underground nuclear waste store

    Two remotely-operated cameras have sent back video and photos of the intermediate-level radioactive waste stored in Dounreay’s wet silo. The images will give the silo decommissioning team a better idea of the condition of the silo and its cargo of waste. The silo is an underground concrete-lined, two-compartment vault where approximately 500 cubic metres of active waste was sent for storage over ...

  • Government consults on nuclear waste policy

    Decommissioning Dounreay generates a variety of different wastes that need to be managed carefully to protect the public and environment from harm. Some of this waste is radioactive. The most hazardous form of radioactive waste generated at Dounreay is known as intermediate-level waste and comes from a variety of redundant plant such as nuclear reactors, fuel reprocessing and laboratories. A key ...

  • Closure of foreign fuel contracts

    Dounreay entered into contracts in the early 1990s with overseas customers to recycle their spent fuel. This work ceased following a breakdown in one of the chemical plants in 1996. All contracts required the waste generated during reprocessing to be returned to the customer, along with the recovered nuclear material. The Nuclear Decommissioning Authority inherited these contracts from the UK ...

  • Subsea robot dives into nuclear clean-up

    A robotic arm used in underwater environments in the oil and gas industry will be helping Dounreay workers clean out radioactive cells. The manipulator will segregate and package up low and intermediate level waste removed from inside concrete cells as the clean-up of the materials test reactor reprocessing plant gathers pace. The cells contained tanks and pipework which became contaminated ...

  • Tenders sought for new waste disposal site

    Companies are being invited to express interest in tendering for the design and construction of a disposal facility for low-level radioactive waste from the decommissioning of Dounreay and adjacent Vulcan facility. A site adjacent to the former fast reactor research establishment was identified following public consultation and planning permission granted in 2009. Dounreay Site Restoration Ltd ...

  • Tests underway to retrieve underground hazardous waste at Dounreay

    One of the most demanding clean-up jobs ever undertaken in the history of nuclear energy is gathering pace. It involves the recovery and packaging of more than 1500 tonnes of radioactive waste that has lain submerged for up to 50 years in the ground beneath Britain’s abandoned experiment with fast reactors at Dounreay. Tests are underway in Scotland, Germany and the USA to develop the ...

  • Building clean out detects historic nuclear material

    As Dounreay’s decommissioning progresses, tiny amounts of fissile material caught up in nooks and crannies of inaccessible pipework and equipment are being identified. This material had previously been given up as lost and described as “Material Unaccounted For” in Dounreay’s inventory of its nuclear material balance, published annually. With the clean out and demolition of reprocessing plants ...

  • Getting into shape for GBP 150m programme

    Dounreay Site Restoration Ltd this week updated staff and local community leaders about the shape of its decommissioning programme following January’s announcement about how much funding will be available in future. The Nuclear Decommissioning Authority has set a budget of up to £150 million a year. This is the basis of the Dounreay competition ...

  • NDA sets out clean-up priorities for Dounreay

    The Nuclear Decommissioning Authority’s annual business plan, published today, sets out the key activities it expects to see carried out at Dounreay over the next 12 months. These range from destroying 50 per cent of the liquid metal still inside the Dounreay Fast Reactor to targets for solidifying more of the liquid waste from historical fuel ...

  • Clean-up removes 29 `significant` particles from seabed

    More than a hundred fragments of spent nuclear fuel were removed from the seabed in the latest phase of work to clean up and shut down the former nuclear research site at Dounreay. The particles were detected and retrieved by a remotely-operated vehicle that systematically scanned an area of seabed equivalent in size to more than 10 football pitches. ...

  • No let-up for holidays in hazard reduction at Dounreay

    There was no let-up during Christmas and New Year in the drive to rid Dounreay of two of its most hazardous legacies. Teams worked around the clock during the holidays to treat more of the toxic liquors left over from the site’s research programme. They kept two of the site’s most important clean-up plants running 24 hours a day throughout Christmas and New Year. At the Dounreay Fast Reactor, ...

  • Removal of building crane important step in demolition

    A building crane in one of Dounreay’s shut-down facilities became a waste package itself when a much larger crane reached in through the roof and lifted it off its rails. The decontamination and waste handling facility, code named D1207, was built to serve Dounreay’s chemical plants and the next door Vulcan site. The electrical overhead travelling (EOT) gantry crane, which had a 7.5 ton capacity, ...

  • High Court orders site owner to clear Orpington site

    The Environment Agency has successfully secured a full High Court order against Waste4Fuel Limited and Mr. Bryan Hughes, the director of the waste facility in Orpington, requiring them to clear the site of combustible waste or be held in contempt of court At a hearing at the High Court, the judge signed an order compelling Waste4Fuel Limited and Company Director Mr Bryan Hughes to clear the site ...

  • Survey detects contamination on proposed waste disposal site

    Two small areas of radioactive contamination have been detected during a survey of grazing land adjacent to the former nuclear research site at Dounreay. They were excavated and removed to the site for analysis. One was identified as a 'minor' particle of fast reactor fuel and the other as soil contaminated with radioactivity. The finds were 5-30cm below the surface and covered by vegetation, ...

  • Climate protection on industrial sites

    Refuse derived fuels in industrial power plants help to save CO2 Power plants on industrial sites can reduce the owner's costs for power, steam or heat production. Onsite power stations also help to prevent CO2 emissions if fossil feedstocks are substituted with refuse derived fuels (RDF). At the 'waste to energy' on May 9 to 10, 2007 in the Bremen Convention Center, experts from Germany and ...
