The terms of the 2009 sale of seven advanced gas-cooled reactor nuclear power plants to EDF Energy "placed a disproportionate amount of risk for meeting future decommissioning costs on the taxpayer," the UK House of Commons Public Accounts Committee said in a report published on 20 May.

USA-based engineering group Jacobs has been selected by Tokyo Electric Power Company to support decommissioning efforts at its damaged Fukushima Daiichi nuclear power plant in Japan. The announcement came as the head of the International Atomic Energy Agency said there had been "remarkable progress" in decommissioning the site.

EDF Energy has started removing the used fuel from the core of Hunterston B's Reactor 3, an advanced gas-cooled reactor that shut down in November 2021. Defuelling is the first stage of the nuclear decommissioning process.

The final cask of used fuel has been transferred from the reactor buildings at Lithuania's shut down Ignalina nuclear power plant to an on-site interim storage facility.

TN Americas - a subsidiary of Orano USA - has been selected by Pacific Gas and Electric Company to offload and transfer all used nuclear fuel and Greater-Than-Class C radioactive waste into interim onsite dry storage at Diablo Canyon nuclear power plant in California. The plant is scheduled to shut down in August 2025.

Dounreay Site Restoration Ltd and the Robotics and Artificial Intelligence in Nuclear Hub are collaborating to develop a robot capable of accessing areas that are inaccessible or unsafe for humans to work in. The announcement came as the first network of robotics and artificial intelligence collaboration hubs across the UK was launched.

Holtec International of the USA and Hyundai Engineering & Construction of South Korea have agreed to cooperate in the area of nuclear plant decommissioning. Last year, the two companies finalised an agreement for the turnkey supply of Holtec's SMR-160 small modular reactor plant worldwide.

EnergySolutions and Radiation Safety & Control Services will form a joint venture to decommission the world's first nuclear-powered merchant ship, the NS Savannah. The work will involve removing the ship's reactor system so that the vessel can be used as a museum.

The first rail transfer of stainless steel drums of waste from the Winfrith Magnox site to Nuclear Waste Services' Low Level Waste Repository site has been completed. The waste's radiation levels have decayed sufficiently for it now to be reclassified as low-level waste.

Germany's Uniper Anlagenservice GmbH has become the first company to complete the dismantling, segmentation and packaging of two reactor pressure vessels in parallel within one year. In December 2021, the company successfully completed the dismantling of the vessels of both Sweden's Barsebäck unit 1 and Germany's Neckarwestheim I.

Sellafield Ltd's Programme and Project Partners has announced the winners of a mechanical and pipework framework agreement. Balfour Beatty Kilpatrick and Doosan Babcock have been appointed to the framework, which is worth GBP112-237 million (USD148-312 million) over the 18-year life of the programme.

Norwegian Nuclear Decommissioning has awarded a NOK123 million (USD13.7 million), 12-year contract to the ICCircle consortium for the design, development and maintenance of a bespoke integrated software system to support nuclear decommissioning and waste management.
