Settlement reached over Summer equipment ownership

Today’s U.S. commercial nuclear power plants are fueled with uranium dioxide pressed into cylindrical ceramic pellets—and have been for decades. These pellets are stacked inside long fuel rods made of a zirconium alloy cladding. Innovation in nuclear fuel, however, can improve safety, reduce operating costs, and further enable the development of a new generation of non-light-water reactors.

Hitachi Ltd. plans to close Horizon Nuclear Power, its U.K. nuclear development subsidiary, early this spring, according to weekend news reports. Horizon is the firm behind Wylfa Newydd, the proposed nuclear new-build project in Wales.

On January 10, citing a story that appeared earlier that day in The Times, Yahoo reported that Hitachi will close Horizon by March 31—a move, Yahoo said, that “could scupper a sale of the [Wylfa Newydd] site, which has attracted interest from bidders, including a U.S. consortium of Bechtel, Southern Company, and Westinghouse, and dent [the] U.K.’s clean energy goals.”

However, a January 11 item on a Welsh online news service stated, “It is understood that if a sale of the site is not secured before Horizon shuts, the sale process will be continued by Hitachi.”

Baranwal

Rita Baranwal, the Department of Energy’s assistant secretary for the Office of Nuclear Energy, announced today via Twitter that she will be leaving her position at the end of the day. “It has been an absolute honor to serve in this capacity to help advance our U.S. nuclear energy R&D,” she tweeted. “I plan to continue to use my talents to promote, lead, and advance our nation’s largest source of clean energy so that our nation and my family will have a cleaner and more sustainable planet to protect.”

Baranwal previously directed the Gateway for Accelerated Innovation in Nuclear (GAIN) initiative at Idaho National Laboratory. Before joining the DOE, Baranwal served as director of technology development and application at Westinghouse. She is a Fellow of the American Nuclear Society.

• Defense Department invests in three microreactor designs: Three reactor developers got a boost on March 9 when they each were awarded a contract from the U.S. Department of Defense to design a reactor that can fit inside a standard shipping container for military deployment. Read more.

The Nuclear Regulatory Commission has announced the establishment of an Atomic Safety and Licensing Board to address a hearing request filed last month concerning Dominion Energy’s subsequent license renewal (SLR) application for the two reactors at its North Anna plant. The application, submitted in August of last year, was docketed by the NRC in October.

The contention: Filed by three anti-nuclear groups—Beyond Nuclear, the Sierra Club, and the Alliance for a Progressive Virginia—the 71-page hearing request argues that Dominion’s environmental report, submitted in support of its application, “fails to satisfy” the National Environmental Policy Act, as well as 10 CFR 51.53(c)(2) and 51.45(a), “because [the report] does not address the environmental impacts of operating North Anna Units 1 and 2 during the extended SLR term under the significant risk of an earthquake that exceeds the design basis for the reactors.”

The January/February 2021 issue of Popular Mechanics hit subscriber mailboxes this week with a stark cover image of a single small reactor under the headline, “Tiny nuclear reactors are about to revolutionize American energy.” The story looks at advanced reactors as a pivotal step to “redeem nuclear’s stature in American energy.”

A good primer: The article does a good job introducing the casual reader to the idea that “bigger is no longer better” and that the future of nuclear power in the United States will most likely be “a combination of traditional large plants and smaller, safer megawatt reactors.”

Advanced reactors, including small modular reactors, show that nuclear is no longer a one-size-fits-all operation, the article notes. The industry now “is all about personalization,” says Ken Canavan, Westinghouse’s chief technical officer, who is quoted in the article. The capacity and scalability of SMRs “is just irreplaceable,” he adds.

The article explains that SMRs, microreactors, and other advanced reactor designs will be able to bring reliable, carbon-free power to small or remote locations, replacing fossil fuel power plants and supplementing the “resource-sucking downtimes left by renewables.”

The Department of Energy today announced $30 million in initial fiscal year 2020 funding—with the expectation of more over the next seven years—for five companies selected for risk reduction for future demonstration projects. The chosen reactor designs from Kairos Power, Westinghouse, BWX Technologies, Holtec, and Southern Company collectively represent a range of coolants, fuel forms, and sizes—from tiny microreactors to a molten salt reactor topping 1,000 MWe. They were selected for cost-shared partnerships under the Office of Nuclear Energy’s Advanced Reactor Demonstration Program (ARDP) through a funding opportunity announcement issued in May 2020.

“All of these projects will put the U.S. on an accelerated timeline to domestically and globally deploy advanced nuclear reactors that will enhance safety and be affordable to construct and operate,” said Energy Secretary Dan Brouillette. “Taking leadership in advanced technology is so important to the country’s future, because nuclear energy plays such a key role in our clean energy strategy.”

A 170-page energy white paper, Powering Our Net Zero Future, issued by the United Kingdom government on December 14 sets big goals for cleaning up the U.K.’s energy system. According to the U.K. government, the plan would create and support green energy jobs across England, Scotland, Wales and Northern Ireland and would keep electricity bills affordable as the U.K. transitions to net zero emissions by 2050.

The white paper notes that the U.K. will generate emission-free electricity by 2050 with a trajectory that will see "overwhelmingly decarbonized power in the 2030s. Low carbon electricity will be a key enabler of our transition to a net zero economy with demand expected to double due to transport and low carbon heat."

The white paper builds upon the U.K. prime minister’s 38-page Ten Point Plan for a Green Industrial Revolution, which was issued on November 18.

In the latest example of the Trump administration’s recent efforts to forge nuclear agreements with Central and Eastern European nations (for other examples, see here, here, and here), the United States earlier this week signed a memorandum of understanding concerning strategic civil nuclear cooperation (NCMOU) with Slovenia.

The NCMOU was signed on December 8 during a visit to Washington, D.C., by a Slovenian delegation headed by Foreign Minister Anže Logar. Signing it were Christopher Ford, the administration’s assistant secretary of state for international security and nonproliferation, and Jernej Vrtovec, Slovenia’s minister of infrastructure.

The previous day, Logar met with Secretary of State Mike Pompeo to discuss, among other topics, “the importance of energy security and how civil nuclear cooperation can strengthen the strategic bilateral relationship,” according to a State Department readout.

Dominion Energy has agreed to pay a civil penalty of $25 million to settle a lawsuit brought by the Securities and Exchange Commission against SCANA Corporation and subsidiary South Carolina Electric & Gas (SCE&G) regarding SCANA’s involvement in the failed Summer nuclear expansion project. Virginia-based Dominion acquired SCANA in January 2019.

Dominion disclosed in May that it had reached an “agreement in principle” with the staff of the SEC’s Division of Enforcement to settle the case for the above-stated amount.

The final agreement, which at this writing is still subject to approval by the U.S. District Court for the District of South Carolina, also calls for the payment of $112.5 million in “disgorgement plus prejudgment interest.” This penalty, however, will be deemed satisfied by SCANA and SCE&G’s settlement payments in related rate payer and shareholder litigation.
