New design center supports construction of Hinkley Point C

A BBC News story from late last week states that the U.K. government “is close to giving the green light” to EDF Energy’s proposed Sizewell C nuclear new build project in Suffolk, adding that details surrounding the project’s financing “are still being hammered out.”

The Sizewell C station, consisting of twin European pressurized reactors (EPRs), would be built next to Sizewell B, a 1,198-MWe pressurized water reactor that began operation in 1995. (The Sizewell site also houses Sizewell A, a 290-MWe Magnox gas-cooled reactor, but that unit was permanently shuttered in 2006.) Sizewell C would be a near copy of the two-unit Hinkley Point C station, currently under construction in Somerset.

“The world needs a mix of renewable power sources, including one that can carry on producing power when the others can’t—the sun doesn’t always shine and the wind doesn’t always blow,” British journalist Jonathan Gornall writes in an opinion piece posted Wednesday on the Asia Times website. Gornall argues that the residents of Suffolk County in the United Kingdom would be better served by the expansion of the Sizewell nuclear power plant than by leaving a wooded area untouched.

The Nuclear Industry Association (NIA), the trade group for the United Kingdom’s civil nuclear industry, unveiled a new report yesterday that sets out a framework for cutting the cost of building new nuclear power plants in Britain.

The 27-page report, Nuclear Sector Deal: Nuclear New Build Cost Reduction, is available online.

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 French nuclear safety authority, Autorité de Sûreté Nucléaire (ASN), has released an International Atomic Energy Agency report on a pre-operational safety review team (pre-OSART) mission conducted in 2019 at the Flamanville nuclear plant to review the safety status of its Unit 3 EPR reactor, currently under construction.

According to the report, the pre-OSART mission at Flamanville-3 reviewed the following areas: leadership and management for safety, training and qualification, operations, maintenance, technical support, operating experience feedback, radiation protection, chemistry, emergency preparedness and response, accident management, human-technology-organization interaction, and commissioning. The review was performed by a team from Canada, Finland, Germany, Russia, Spain, Sweden, and the United States, along with IAEA staff members and observers from Russia and South Korea.

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.

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.

A report published last week by Energy Systems Catapult, a U.K.-based clean energy nonprofit, concludes that adding double-digit gigawatts of new nuclear is a “low-regrets option” for the United Kingdom as it strives to achieve net-zero carbon emissions by 2050. (Legislation establishing the 2050 target date was signed in June of last year, making the United Kingdom the first of the world’s major economic powers to take that step.) The report also stresses, however, that costs for new nuclear must decrease significantly for the technology to meet its potential.

Citing reports that China has recently threatened to pull its support for new nuclear build in the United Kingdom, U.S. Secretary of State Mike Pompeo on June 9 offered assistance from the United States and vehement criticism of Beijing.
