The United Kingdom has announced a northern Wales site as its preferred location for a third mega-nuclear power station as the nation aims to support long-term energy security.

Following its plans to build nuclear facilities at Hinkley in Somerset and Sizewell in Suffolk, both in England, U.K. officials hope to revive the nuclear history of Wylfa, in Wales, and bring thousands of jobs and major investment to the area. The government is kickstarting talks with global energy firms in hopes of building a nuclear plant in Wylfa that could provide enough energy to power 6 million homes for 60 years.

The effort to build the Hinkley Point C nuclear power plant in Somerset, England, has been “prodigious, lengthy, and increasingly costly.” So says London-based energy, business, and environment writer Stanley Reed in his recent New York Times article, “Why Britain Is Struggling with Nuclear Power.”

EDF Energy, owner and operator of the United Kingdom’s nuclear reactor fleet, announced last week that it intends to keep its Hartlepool and Heysham 1 stations in operation to March 2026—two years past their previously scheduled 2024 retirement dates. EDF added that an additional 12 months of operation beyond 2026 is being contemplated.

On the sidelines of the first European Political Community (EPC) summit in Prague last week, U.K. prime minister Liz Truss and French president Emmanuel Macron met to discuss bilateral cooperation, with a particular focus on the energy sector. (Macron proposed the creation of the EPC earlier this year, following Russia’s invasion of Ukraine. Representatives of 44 European countries participated, as did the presidents of the European Council and European Commission. Conspicuously uninvited were Russia and Belarus.)

The U.K. government has released a new energy strategy aimed at boosting Britain’s energy independence, stabilizing its soaring energy prices, and accelerating the deployment of new nuclear, wind, solar, and hydrogen to mitigate climate change.

At the same time, the 38-page document, British Energy Security Strategy, calls for near-term support for domestic oil and gas, stating, “Net zero is a smooth transition, not an immediate extinction, for oil and gas.” (The United Kingdom in 2019 became the first of the world’s major economies to embrace a legal obligation to achieve net-zero carbon emissions by 2050.)

Following through with this strategy, the government says, could result in low-carbon sources generating up to 95 percent of British electricity by 2030.

The Hunterston B nuclear power plant has ended its nearly 46 years of zero-carbon electricity generation for Scotland with the shutdown of Unit B2. The 495-MWe advanced gas-cooled reactor (AGR), which began commercial operation in March 1977, was taken off line on January 7. The station’s companion unit, the 490-MWe AGR B1, was shut down last November.

Under an agreement with the U.K. government signed on June 23, 2021, EDF Energy, owner and operator of Britain’s power reactor fleet, is responsible for defueling all seven of the U.K.’s AGR nuclear stations over this decade. (The agreement does not include Sizewell B, which houses a 1,098-MWe pressurized water reactor slated to continue operating until at least 2035, or Hinkley Point C, which is currently under construction.) EDF expects the defueling of the AGR facilities to take from three-and-a-half to five years.

Scheduled to follow Hunterston B into the defueling phase by July of this year is the two-unit Hinkley Point B plant in Somerset, England.

Unit B1 at Scotland’s two-unit Hunterston B nuclear power plant was taken off line for good on November 26 after nearly 46 years of operation. A 490-MWe advanced gas-cooled reactor, the unit entered commercial operation in June 1976. Its companion AGR, Unit B2, which entered operation in March 1977, is scheduled for retirement in January.

A recent study of life cycle carbon emissions at the United Kingdom’s Hinkley Point C nuclear plant finds that the facility, now under construction in Somerset, England, is likely to produce less CO₂ over its lifetime than either solar or wind power.

According to the 70-page analysis—prepared by environmental consultancy Ricardo Energy & Environment for NNB Generation Company HPC Limited, the holding company for the Hinkley Point project—lifetime emissions from Hinkley Point C are likely to be about 5.5g CO₂e per kWh. That amount also holds for the proposed Sizewell C plant, the study concludes. (The two 1,630-MWe EPRs at Hinkley Point C are currently scheduled to begin commercial operation in 2026 and 2027.)

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.

The unfortunate effects of the COVID-19 pandemic on nuclear new-build projects haven’t stopped with Vogtle: EDF Energy this morning reported that the expected startup date for Unit 1 at its Hinkley Point C site is being pushed from late 2025 to June 2026.

In addition, the project’s completion costs are now estimated to be in the range of £22 billion to £23 billion (about $30.2 billion to $31.5 billion), some £500 million (about $686 million) more than the 2019 estimate, EDF said, adding the caveat that these revisions assume an ability to begin a return to normal site conditions by the second quarter of 2021.

The United Kingdom, the first of the world’s major economies to adopt a legally binding commitment to achieve net-zero greenhouse gas emissions by 2050, has released a blueprint to help realize that goal—one that includes a substantial role for nuclear energy

The Ten Point Plan for a Green Industrial Revolution will mobilize a total of £12 billion (about $16 billion) of government investment to create and support up to 250,000 highly skilled green jobs in the United Kingdom and spur over three times as much private sector investment by 2030, according to the UK government on November 18.

In addition to nuclear, offshore wind, hydrogen production, carbon capture, and vehicle electrification are also earmarked for significant investment in the 38-page document.

EDF Energy has made a “proactive decision” to move Britain’s Hinkley Point B power station into its defueling phase no later than July 15, 2022—some eight months earlier than previously scheduled—the company announced on November 19.

The two-unit plant, located in Somerset, England, began generating electricity in 1976 and has since produced more than 300 TWh of power, enough to meet the electricity requirements of every home in the United Kingdom for three years, according to EDF.

“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.

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.

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.

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.
