In a 243–187 vote, the House of Representatives yesterday passed the CHIPS and Science Act of 2022, a $280 billion economic competitiveness package aimed at bolstering U.S. semiconductor manufacturing, as well as scientific research and development, including nuclear energy R&D.
Nuclear energy offers a pairing of high capacity factors and low carbon emissions unrivaled by other power sources, and advanced reactors and small modular reactors (SMRs) hold promise to deliver that power with even more efficiency and versatility. Researchers in the public and private sectors, backed by government funding through programs like the Department of Energy’s Advanced Reactor Demonstration Program and Advanced Research Projects Agency–Energy (ARPA-E), are bringing that promise closer to fulfillment by engineering solutions to open questions about advanced reactor materials and fuel cycles.
The DIII-D National Fusion Facility now boasts a unique automated system that allows for a quick reversal of the direction of its magnetic field, expanding the range of possible fusion experiments while reducing downtime. General Atomics, which operates the DIII-D for the Department of Energy’s Office of Science, announced the new Toroidal Field Reversing Switch (TFRS) on July 26.
The Nuclear Regulatory Commission recently approved, in a 2–1 vote, a recommendation from its staff that could potentially lead to the siting of advanced reactors in more densely populated areas than is permitted for traditional light water units.
NRC chairman Christopher Hanson and David Wright voted in favor of the recommendation, with Jeffery Baran casting the lone “nay” vote. (There are currently two open seats on the five-member commission.)
The Department of Energy today issued a Record of Decision (ROD) for the Final Versatile Test Reactor Environmental Impact Statement (final VTR EIS; DOE/EIS-0542). The VTR will be a sodium-cooled, fast-neutron-spectrum test reactor that will enhance and accelerate research, development, and demonstration of innovative nuclear energy technologies critical to tackling the climate crisis, according to the DOE.
The VTR ROD and final VTR EIS are available for viewing or download here.

The Belgian government has signed a nonbinding letter of intent with Electrabel, a subsidiary of the French utility Engie, to keep nuclear a part of Belgium’s energy mix for an additional 10 years.
Electrabel operates Belgium’s two nuclear power plants, the four-unit Doel and three-unit Tihange.
Romania’s Nuclearelectrica, the state-owned operator of the two-unit Cernavoda nuclear power plant, has awarded Candu Energy a contract to conduct design and engineering services for the facility’s Unit 1 refurbishment project, according to an announcement last week from SNC-Lavalin, Candu Energy’s parent company.
The June 2017 special report on the ANS Nuclear Grand Challenges (available online at ans.org/challenges/) identified low-dose radiation as a crucial focus area for ANS. Specifically, the challenge is to “Establish the scientific basis for modern low-dose radiation regulation.” This is particularly difficult given the long review cycles associated with International Commission on Radiological Protection (ICRP) and National Council on Radiation Protection and Measurements (NCRP) recommendations. Additionally, while the Environmental Protection Agency is tasked with issuing guidance on radiation exposure standards in the United States, responsibility for implementing and enforcing radiation protection regulations is distributed throughout the federal government. Finally, while it is accepted that tissue reactions (previously called deterministic or nonstochastic effects) exhibit a dose threshold, there is still substantial scientific debate over the shape of the dose response at low doses for stochastic effects, such as cancer. Despite these hurdles, substantial progress has been made over the past five years on the low-dose radiation grand challenge.
The Department of Energy earlier this year approved part one of a loan application from Holtec International for small modular reactor construction and invited the firm to apply for a loan to help build four of its SMR-160 units and grow its manufacturing capacity to produce the first wave of SMRs.
While the construction of two additional reactors at Slovakia’s Mochovce nuclear plant (Units 3 and 4) may get most of the attention, it isn’t the only major project underway there. In October of last year, plant owner Slovenské Elektrárne commenced the first phase of an effort to revitalize two of the four 125-meter-tall, Iterson-type cooling towers that serve the facility’s two operating reactors—both of which began generating electricity in the late 1990s. Towers #11 and #21 had been refurbished in 2011 and 2012, respectively. The other two, however, towers #12 and #22, had never undergone refurbishment.
Rockville, Md.–based X-energy announced yesterday that it has selected Zachry Group and a combined team from Burns & McDonnell and Day & Zimmermann to work with the company on the next phases of design and deployment for its Xe-100 small modular reactor fleet.
When the Department of Energy announced Innovation Network for Fusion Energy (INFUSE) awards earlier this month, Savannah River National Laboratory was named a recipient of two of the 18 awards. SRNL released a statement on July 19 explaining how a national lab with a long history of supporting environmental management and national security missions can lend a hand in the development of future commercial fusion power.
The U.K. government has granted a development consent order (DCO) for EDF Energy’s proposed Sizewell C plant near Leiston in Suffolk, moving the new nuclear build project closer to a reality.
Nuclear New Build (NBB) Generation Company, an EDF Energy subsidiary, submitted the DCO application to the government’s Planning Inspectorate in May 2020, setting out the range of measures the project would implement to mitigate construction effects and maximize community benefits. The Planning Inspectorate accepted the application in June 2020 and completed its examination in October 2021. Recommendations were made to the secretary of state for business, energy, and industrial strategy this February.
California-based TAE Technologies has announced that its accomplishments with its fifth-generation fusion research reactor, Norman, have allowed it to secure sufficient strategic and institutional investments to fund the construction of its sixth-generation research reactor, Copernicus.
As part of its “Made in Ontario” strategy announced last year, Bruce Power has awarded a contract valued at C$130 million (about US$100.8 million) to BWXT Canada in support of the ongoing major component replacement (MCR) project at the utility’s eight-unit Bruce nuclear plant.
Kairos Power needs a source of high-purity fluoride salt to test its molten salt reactor design and ultimately to serve as the coolant in its grid-scale fluoride salt–cooled, high-temperature reactor (KP-FHR). As part of a cooperative development agreement with Materion Corporation, Kairos Power designed a molten salt purification plant (MSPP) that has just been commissioned at Materion’s campus in Elmore, Ohio.
