The U.K. government and EDF have agreed to improved arrangements for the decommissioning of Britain’s seven advanced gas-cooled reactor nuclear power plants, which are due to reach the end of their operational lives this decade.

EDF Energy, owner and operator of the United Kingdom’s nuclear reactor fleet, yesterday announced its decision to move the Dungeness B nuclear plant into its defueling phase “with immediate effect,” rather than proceed with a restart later this year. The company had previously stated that it intended to operate the facility, located in southeastern England, until at least 2028.

EDF has signed a new membership agreement with the United Kingdom’s Nuclear Advanced Manufacturing Research Centre (AMRC) to drive innovation in low-carbon power generation and support U.K. manufacturers, the University of Sheffield–based center announced recently.

Czech Republic political parties have agreed to exclude China from participating in a tender to build an additional reactor at the Dukovany nuclear plant but have yet to decide whether to allow Russian participation, according to a report last week from Reuters.

Other bidders on the project, estimated to be worth some €6 billion (about $7.2 billion), include Korea Hydro & Nuclear Power of South Korea, EDF of France, and Westinghouse of the United States.

EDF Energy has received approval from the United Kingdom’s Office for Nuclear Regulation (ONR) to restart the Hunterston B power station’s Unit 3 for a limited run, according to August 27 announcements from both the company and the regulator. EDF has permission to operate the unit for up to 16.425 terawatt days (approximately six months of operation), the ONR said.

EDF also announced that Hunterston B—located in North Ayrshire, along the western coast of Scotland—will begin its defueling phase no later than January 7, 2022, more than a year earlier than the expected retirement date of March 2023. The decision, EDF said, was made following a series of executive board and shareholders meetings.

The Enforcement Committee of the Autorité des Marchés Financiers (AMF) has imposed a fine of €5 million (about $5.9 million) on Électricitéde France for providing false information about the Hinkley Point C new-build nuclear project in the United Kingdom. The committee has also imposed a €50,000 (about $59,000) fine on EDF’s former chairman and chief executive officer, Henri Proglio. According to a July 30 statement from the AMF, the false information was spread via an October 8, 2014, news release.

The AMF is described on its website as an independent public authority that regulates the French financial marketplace and its participants.

Exelon Generation and Électricitéde France have asked the New York Public Service Commission to approve the transfer of EDF’s 49.99 percent ownership interest in Constellation Energy Nuclear Group (CENG) to Exelon, which owns 50.1 percent. CENG is the owner of New York’s Ginna and Nine Mile Point nuclear plants, as well as Maryland’s Calvert Cliffs.

EDF Energy has opened a new engineering design facility in Bristol, England, to support the next phase of construction at the Hinkley Point C nuclear power station in Somerset, the company announced on July 14. The UK EPR Design Centre at Aztec West brings together nuclear designers and engineers from EDF and British engineering partners and suppliers, including Framatome UK, Atkins, Jacobs, Assystem, Anotech, and Vulcain, the announcement said.

After producing electricity generation for more than 40 years, Fessenheim-2 was disconnected from the grid on June 29, some four months after the retirement of its companion reactor, Fessenheim-1 (NN, Mar. 2020, p. 83). The action completes the closure of what had been France’s oldest operating nuclear power facility.

Both Fessenheim units are 880-MWe pressurized water reactors; Unit 1 began commercial operation in December 1977, with Unit 2 going on line in March 1978.

Workers at the Hinkley Point C nuclear construction project in the United Kingdom have completed the 49,000-ton base for the station’s second reactor, Unit C2, hitting a target date set more than four years ago, according to EDF Energy.

Électricité de France subsidiary EDF Energy has submitted an application to the United Kingdom government’s Planning Inspectorate for a development consent order (DCO) to build a new power station, Sizewell C, at the Sizewell nuclear site in Suffolk. The agency received the application on May 27, after it had been deferred for two months because of the COVID-19 pandemic.
