The United Kingdom’s Office for Nuclear Regulation (ONR) has granted permission for the start of bulk mechanical, electrical, and HVAC component installation work at the Hinkley Point C site in Somerset, England, where two 1,630-MWe EPRs are under construction. Thus far, most of the activity at Hinkley Point C has been in the field of civil construction.

This new phase, according to ONR, will require a workforce of up to 4,000 during peak times, including welders, pipe fitters, and electricians. The work is to be accomplished over a three-year period, with NNB Genco—the EDF Energy subsidiary set up in 2009 to build and operate Hinkley Point C—teaming up with four suppliers: Balfour Beatty Bailey, Doosan, Cavendish, and Altrad.

Two GOP lawmakers are calling on the Government Accountability Office to undertake an assessment of the Nuclear Regulatory Commission’s preparedness to review and approve advanced reactor applications.

In a February 4 letter to the GAO, Sen. Shelley Moore Capito (R., W.Va.), ranking member of the Senate Environment and Public Works Committee, and Rep. Cathy McMorris Rodgers (R., Wash.), ranking member of the House Energy and Commerce Committee, wrote, “Recent NRC actions concerning certain licensing activities raise questions about the agency’s capability to manage effectively first-mover applications for new, advanced technologies.”

Small modular reactor developer NuScale Power has informed the Nuclear Regulatory Commission via letter that a combined license application (COLA) for the Carbon Free Power Project’s SMR plant is expected to be submitted to the agency in January 2024. The COLA will be for a six-unit 77-MWe plant.

The public power consortium Utah Associated Municipal Power Systems launched the Carbon Free Power Project in 2015 to develop, own, and operate the nation’s first SMR plant, to be located at Idaho National Laboratory, with reactor technology supplied by NuScale.

Seventy-nine scientific and business luminaries, including a number of the world’s leading experts on climate and energy, have signed a letter imploring California Gov. Gavin Newsom to postpone the premature retirement of the Diablo Canyon nuclear power plant, currently slated for closure in 2025.

The European Commission gave two cheers for nuclear energy yesterday with its adoption of the Complementary Climate Delegated Act (CDA), which adds—under what the EC refers to as “clear and strict conditions”—nuclear and natural gas to the list of green technologies covered by the EU taxonomy. (The taxonomy is the classification system used by the European Union to guide private investment toward environmentally sustainable economic projects.)

Lee

In his annual State of the State Address on January 31, Tennessee Gov. Bill Lee offered more praise for nuclear energy, after lauding it earlier in the month during a tour of the Tennessee Valley Authority’s Watts Bar nuclear plant

“For decades, East Tennessee has been home to some of the best-kept secrets in nuclear energy and American innovation,” Lee told the state’s General Assembly. “Today, many may not realize that Tennessee derives more power from nuclear energy than from any other source. Recently, I visited the TVA’s Watts Bar nuclear facility, the last nuclear facility to be built in America, to see firsthand how nuclear power keeps our grid dependable even when the weather is not. Nuclear power is clean energy that actually works for the private sector.”

Alaska Gov. Mike Dunleavy (R.) introduced “An act relating to microreactors” (SB 177) in the Alaska state legislature on February 1 that would modify existing state law on nuclear energy by specifying that microreactors are not subject to certain nuclear reactor siting and permitting regulations in Alaska. The bill defines a microreactor as an advanced nuclear fission reactor that would be capable of generating no more than 50 MWe.

A spokesperson for Georgia Power has confirmed that the projected in-service date for the new Vogtle-3 reactor remains the third quarter of 2022, according to an article published on January 27 on the Power magazine website. The in-service date for Vogtle-4 is targeted for the second quarter of 2023, the spokesperson said.

During a tour last week of the Tennessee Valley Authority’s two-unit Watts Bar nuclear power plant in Tennessee, Gov. Bill Lee said, "Nuclear energy is so important not only because it is an important part of TVA's power generation but also because of the value that clean energy via nuclear energy can have for sustainability in this country,” according to an article in the Chattanooga Times Free Press.

Lee added that he would support TVA’s plans if it decided to build small modular reactors.

Doriot

Koch

A new bill in the Indiana state Senate creates guidelines for state regulators to consider small modular reactors should utilities want to build them. Senate Bill 271 was sponsored by Sen. Eric Koch (R., Bedford), chair of the Senate Utilities Committee, and Sen. Blake Doriot (R., Goshen). Supporters of the bill said that SMRs could replace retiring coal plants and would supplement renewables.

The Indy Star reported on January 24 that the utilities committee passed the bill by a vote of eight to two and that it now heads to the full Senate.

The Intergovernmental Panel on Climate Change (IPCC)—the United Nations body established to assess the science related to climate change—is offering experts an opportunity to review the draft version of its Sixth Assessment Synthesis Report.

IPCC assessment reports are published every six to seven years. The Fifth Assessment Report, completed in 2014, provided the main scientific input to the 2015 Paris Agreement.

Interested experts can register for participation in the review here. Registration is open through March 13. The review period ends on March 20.

Despite last year’s announcement from EDF Energy that the startup of Unit 1 at Hinkley Point C would likely be delayed (from late 2025 to June 2026), current progress at the site is receiving praise from the U.K. government.

On January 13, Kwasi Kwarteng, secretary of state for business, energy, and industrial strategy, and Helen Whately, exchequer secretary of the treasury, toured the nuclear new-build project, accompanied by Jean Bernard Lévy, EDF’s chairman and chief executive.

The International Energy Agency’s newly published in-depth review of Canada’s energy policies, the first since 2015, urges the nation’s government to take more action in support of nuclear energy.

The 261-page report, Canada 2022 Energy Policy Review, released on January 13, features a 17-page section devoted to nuclear that includes four specific recommendations for Canada’s federal government:

The Nuclear Regulatory Commission’s announcement earlier this month that it was denying Oklo Power’s license application to build and operate its Aurora microreactor in Idaho caught a lot of people by surprise, not the least of whom were the people at Oklo.

France’s Flamanville-3 project, plagued by schedule setbacks and cost overruns for well over a decade (construction of the unit commenced in December 2007), will be delayed a bit longer and cost a bit more.

Électricité de France announced yesterday that fuel loading at the 1,600-MWe EPR has been pushed back from the end of this year to the second quarter of 2023. The delay increases the project’s cost at completion from €12.4 billion (about $14.2 billion) to €12.7 billion (about $14.5 billion), more than four times the initial estimate of €3.3 billion, according to EDF.

Over the past couple of months, the nuclear community has participated in a grassroots effort to save the Diablo Canyon nuclear power plant from premature closure—and it appears to be having an effect. The growing support for keeping Diablo Canyon open is seen in editorials, an academic study from Stanford/MIT, and a grassroots rally held in December 2021 to show support for keeping Diablo Canyon operating.

Foratom, the Brussels-based trade association for the European nuclear industry, wrote a letter yesterday to the European Commission welcoming the EC’s recent proposal to include nuclear in the EU taxonomy (under certain conditions), but also offering some suggestions for the proposal’s improvement.

The taxonomy is the European Union’s classification system for directing investments toward environmentally sustainable economic projects. On December 31, the EC’s nuclear-inclusive proposal was sent to expert panels from EU member states, with a response deadline of today. At a news briefing yesterday, however, an EC spokesperson announced an extended deadline of January 21.

In a wide-ranging “program statement” laying out its policy priorities, the Czech Republic’s new, center-right government has endorsed nuclear energy and renewables and called for power generation from coal to be phased out by 2033.

The final version of the statement was released on January 7 by the five-party coalition government, sworn into office last month and led by Prime Minister Petr Fiala, head of the Civic Democratic Party.

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.
