Nuclear energy was the focus of a recent NPR 1A podcast episode, hosted by journalist Jenn White, who welcomed guests to discuss the role of nuclear energy in the future of the United States. The guests—Joe Dominguez, chief executive officer of Constellation Energy; Samantha Gross, director of the Energy Security and Climate Initiative at the Brookings Institution; and Edwin Lyman, director of Nuclear Power Safety for the Union of Concerned Scientists—participated in the episode, titled “Where Does Nuclear Energy Fit in a Carbon-Free Future?”

With the release last week of the policy paper Powering Up Britain, the U.K. government unveiled its plan to enhance the nation’s energy security and deliver on its ambitious net-zero commitments.

“This document explains how we will diversify, decarbonize, and domesticate energy production by investing in renewables and nuclear, to power Britain from Britain,” writes U.K. secretary of state for energy security and net zero Grant Shapps in the foreword. “It sets out the extraordinary opportunities opening up in technologies like carbon capture, usage, and storage; floating offshore wind manufacturing; and hydrogen, which will not only help us reach net zero but also consolidate Britain’s position as a global leader in green energy. And it details how we will use that leadership to influence energy decarbonization internationally.”

The United Kingdom’s nuclear regulators—the Office for Nuclear Regulation (ONR), the Environment Agency, and Natural Resources Wales (NRW)—have announced the completion of step one of their generic design assessment (GDA) for Rolls-Royce SMR’s 470-MWe small modular reactor design and the start of step two, which is expected to last 16 months.

In a 39–13 bipartisan vote on March 30, the Illinois Senate passed legislation that would end the state’s prohibition on nuclear power plant construction—a ban that has been on the books since 1987.

The United States and Canadian nuclear industries used to be an example of how two independent teams of engineers facing an identical problem—making electricity from uranium—could come up with completely different answers. In the 1950s, Canada began designing a reactor with tubes, heavy water, and natural uranium, while in the U.S. it was big pots of light water and enriched uranium.

But 80 years later, there is a remarkable convergence. The North American push for a new generation of nuclear reactors, mostly small modular reactors (SMRs), is becoming binational, with U.S. and Canadian companies seeking markets and regulatory certification on both sides of the border and in many cases sourcing key components in the other country.

Fortum—operator of Finland’s two-unit Loviisa nuclear power plant—has signed a memorandum of understanding with Finnish stainless steel producer Outokumpu to explore decarbonizing the latter’s manufacturing operations with the help of emerging nuclear technologies, the companies announced on March 23.

The United States and Indonesia have announced a strategic partnership to help the latter nation develop its nuclear energy program, supporting its interest in deploying small modular reactors to meet energy security and climate goals.

The Nuclear Regulatory Commission recently announced that it will begin reviewing most of the standard design approval (SDA) application for NuScale Power’s uprated small modular reactor technology, with the remainder of the review on hold until the company provides additional details on a key safety topic.

“I’m glad you came to our party!” said GE Hitachi Nuclear Energy (GEH) chief nuclear officer Nicole Holmes as she prepared to announce that Wilmington, N.C.–based GEH will develop a standard design for its BWRX-300 boiling water small modular reactor with not one but three power producers representing three countries: Tennessee Valley Authority (TVA), Ontario Power Generation (OPG), and Synthos Green Energy (SGE). Celebration was a theme throughout the March 23 event held in Washington, D.C., which was flush with dignitaries representing the United States, Canada, and Poland.

Hunt

In his spring 2023 budget speech to the House of Commons last Wednesday, U.K. chancellor of the exchequer Jeremy Hunt confirmed that, subject to consultation, nuclear power will be classified as environmentally sustainable in the U.K. green taxonomy, providing potential private investors in nuclear projects access to the same incentives currently enjoyed by investors in renewables. (Last year, the European Union added nuclear and natural gas to the list of green technologies covered by its taxonomy, but only on a transitional basis under what the European Commission termed “clear and strict conditions.”)

“We have increased the proportion of electricity generated from renewables from under 10 percent to nearly 40 percent,” Hunt declared. “But because the wind doesn’t always blow and the sun doesn’t always shine, we will need another critical source of cheap and reliable energy. And that is nuclear.”

GE Hitachi Nuclear Energy’s (GEH’s) BWRX-300 technology has completed phases 1 and 2 of the Canadian Nuclear Safety Commission’s vendor design review (VDR) process, the Wilmington, N.C.–based company announced yesterday.

NuScale Power, the Portland, Ore.–based small modular reactor developer, announced last week that it has placed the first upper reactor pressure vessel (RPV) long-lead material (LLM) production order with South Korea’s Doosan Enerbility.

The origins of the Nuclear Regulatory Commission’s robust international program date back to 1953, when President Eisenhower, in an address to the United Nations, promised to share U.S. nuclear expertise with the world. This commitment underpins our international programs today.

The NRC’s early focus was cooperating with countries operating U.S. reactor technology to leverage collective operating experience. But requests for assistance grew steadily, and the 1986 Chernobyl nuclear accident made clear that international assistance was vital for global safety. We helped promote development of independent regulators in the former Soviet Union, and in a 1994 report, the independent NRC Office of the Inspector General praised how the NRC assisted Ukraine in establishing laws, regulations, and enforcement capacity.

Lightbridge Corporation, which is continuing to work closely with national laboratories on the manufacture and testing of its metallic fuel rod designs for light water reactors, just announced the results of an investigation on the casting process for molten uranium and zirconium with Pacific Northwest National Laboratory under the Department of Energy’s Gateway for Accelerated Innovation in Nuclear (GAIN) program.

Dow and X-energy announced today that they have signed a joint development agreement (JDA) to demonstrate the first grid-scale advanced nuclear reactor at an industrial site in North America within a decade. As part of the agreement, Dow is now a subawardee under X-energy’s Advanced Reactor Demonstration Program (ARDP) Cooperative Agreement with the Department of Energy.

The Canadian Nuclear Safety Commission (CNSC) and Poland’s National Atomic Energy Agency (PAA) have signed a memorandum of cooperation to share best practices and experience in reviewing advanced and small modular reactor technologies. (The two agencies are already engaged in cooperation on nuclear safety matters under a memorandum of understanding inked in 2014.)

Estonia’s Fermi Energia has selected GE Hitachi Nuclear Energy’s BWRX-300 small modular reactor for potential deployment in that European country, GEH announced on February 8.

X-energy Canada, a subsidiary of U.S. mall modular reactor and fuel technology company X-energy, has signed a memorandum of understanding with Invest Alberta Corporation (IAC) to develop economic opportunities in support of the potential deployment of the Xe-100 SMR in the western Canadian province. (Alberta is one of four provinces behind last year’s A Strategic Plan for the Deployment of SMRs—a document that maps the path to capitalizing on the benefits of advanced reactor deployment.)

The nuclear community is undergoing a moment of unprecedented interest and growth not seen in decades. The passage of the bipartisan Infrastructure Investment and Jobs Act and the Inflation Reduction Act are providing a multitude of new funding opportunities for the nuclear community, and not just the current fleet. A mix of technologies and reactor types are being evaluated and deployed, with Vogtle Units 3 and 4 coming on line later this year, the Advanced Reactor Demonstration Projects of X-energy and TerraPower, and NuScale’s work with Utah Associated Municipal Power Systems to build a first-of-a-kind small modular reactor, making this is an exciting time to join the nuclear workforce.

At my company, Dow, we understand and embrace our responsibility to reduce global carbon emissions. With that said, the challenge to decarbonize is significant but achievable. To give you a sense of the scale required for us to decarbonize in order to make our products, we produce more than 7 GW of power and steam that fire more than 50 gas and steam turbines and boilers. Moreover, we have more than 100 furnaces at 30 major manufacturing sites worldwide.

Dow has already reduced our greenhouse gas emissions by 15 percent since 2005, and we are on track to reduce emissions another 15 percent by the end of the decade on our path to carbon neutrality by 2050. Our use of clean energy has contributed significantly to our current progress, as we are one of the top 20 users of renewable energy among global corporations, having secured more than 900 MW of renewable power. While we will continue to pursue renewable energy, there’s a limitation in the ability for renewables to support our decarbonization efforts.
