Jill Hruby was sworn in by energy secretary Jennifer Granholm on July 26 as the Department of Energy’s undersecretary for nuclear security and administrator of the National Nuclear Security Administration. Hruby was nominated for the position by President Biden on April 14.

When Utah Associated Municipal Power Systems (UAMPS) in 2015 announced its plan to develop the Carbon Free Power Project (CFPP) using NuScale Power’s modular light water reactor design, it envisioned the construction of a dozen 50-MWe modules for a plant that could produce a total of 600 MWe. The CFPP’s target output later rose to 720 MWe, when UAMPS opted to scale up to 60-MWe modules. In late June, the plans changed once again, as UAMPS participants chose to build 77-MWe modules but downsize the plant from 12 units to six, which would yield 462 MWe—about 64 percent of the 720 MWe that could have been generated from 12 of the 60-MWe modules.

A statistically predicted tendency for neutrons produced inside fission reactors to form in clusters can cause asymmetrical energy production that is counterbalanced, at least in part, by the spontaneous fission of radioactive material in the reactor.

Today, Tennessee governor Bill Lee joined Department of Economic and Community Development commissioner Bob Rolfe and Kairos Power officials in Nashville, Tenn., to celebrate Kairos’s plans to construct a low-power demonstration reactor in the East Tennessee Technology Park in Oak Ridge, Tenn. The company first announced its plans to redevelop the former K-33 gaseous diffusion plant site at the Heritage Center, a former Department of Energy site complex, in December 2020.

The U.S. Department of Energy has announced $5.8 million in funding to develop three construction technologies that together can reduce the cost of new nuclear builds by more than 10 percent.

The Department of Energy’s Office of Science has named seven companies as the recipients of cost-shared funding granted through the Innovation Network for Fusion Energy (INFUSE). A total of $2.1 million in first-round fiscal year 2021 funding was awarded on July 1 across nine collaborative projects between DOE national laboratories and private industry aimed at overcoming challenges in fusion energy development.

Seventy-five years ago today, on July 1, 1946, the first U.S. national laboratory was chartered with the singular mission of developing the peaceful uses of nuclear energy. Now, the Department of Energy’s Argonne National Laboratory is one of the nation’s largest science laboratories, working on diverse challenges in energy, climate, science, medicine, and national security.

California-based Oklo has received a $2 million cost-share award from the Department of Energy for the commercialization of advanced fuel recycling capabilities by using electrorefining technology. Oklo is matching $1 million in funds and is partnering with the DOE and Argonne National Laboratory on this public-private partnership, which is intended to help reduce fuel costs for advanced reactor designs while reducing waste by turning used fuel into advanced reactor fuel.

More than $61 million in funding has been released for advanced nuclear energy technology projects in 30 states and in the U.S. territory of Puerto Rico, the Department of Energy announced on June 22. Of that total, $58 million is going to U.S. universities for nuclear energy research, cross-discipline technology development, and research reactor infrastructure.

The theme of the 2021 ANS Virtual Annual Meeting—Breaking Through to Deployment—is a theme of action. It can take substantial momentum, shrewdly applied, to break through barriers.

U.S. scientists are getting funding to carry out seven research projects at two major stellarator fusion energy facilities located in Germany and Japan, the Department of Energy announced on June 8. A total of $6.4 million has been allocated for seven research projects with terms of up to three years.

Coolant flow around the fuel pins in a light water reactor core plays a critical role in determining the reactor’s performance. For yet-to-be-built small modular reactors, a thorough understanding of coolant flow will be key to successfully designing, building, and licensing first-of-a-kind reactors.

The definition of a microreactor is ambiguous. But whether your upper cutoff is 10 MW or 20 MW, the Microreactor Applications Research Validation and Evaluation (MARVEL) reactor that the Department of Energy plans to build is, at 100 kW, on the tiny side of micro.

TerraPower has a design for a sodium-cooled fast reactor and federal cost-shared demonstration funding from the Department of Energy. Its partner, PacifiCorp, has four operating coal-fired power plants in the state of Wyoming. On June 2, together with Wyoming Gov. Mark Gordon and others, the companies announced plans to site a Natrium reactor demonstration project at a retiring coal plant in Wyoming, with a specific site to be announced by the end of 2021.

U.S. energy secretary Jennifer Granholm and French minister for the ecological transition Barbara Pompili issued a joint statement on May 28 in which they pledged to work together to meet shared climate goals.

“France and the United States share common goals and common resolve in fighting climate change and working toward reaching the ambitious target set forth by the Paris agreement,” the statement read. “We are united in a common ambition on both sides of the Atlantic: achieving net-zero carbon emissions by 2050. Reaching this common objective will require leveraging all currently existing emission-free technologies available to us while simultaneously intensifying research, development, and deployment across a suite of zero-emissions energy sources and systems. Ensuring that these energy systems are efficient and reliable, integrating larger shares of renewables coupled with nuclear energy, which is a significant part of today’s electricity production in both our countries, will be crucial to accelerate energy transitions. Reaching this common objective will also require a wide variety of favorable financing conditions across the range of zero-emitting power sources and systems.”

The Department of Energy is providing up to $2 million in fiscal year 2022 to fund university and national laboratory studies into the use of novel, medically relevant isotopes for use in pre-clinical and clinical medical trials, the DOE’s Office of Science announced on June 1.

Operators at the Advanced Test Reactor at Idaho National Laboratory have begun a nine-month outage to perform a core internals changeout. When the ATR is restarted in early 2022, the top head closure plate of the pressurized water test reactor will have new access points that could permit the irradiation of more fuel and material samples in the reactor’s high-flux neutron conditions.

The Advanced Test Reactor (ATR) at Idaho National Laboratory is getting an overhaul that will keep it off line for nine months. When the ATR is restarted in early 2022, the one-of-a-kind pressurized water test reactor—which is operated at low pressures and temperatures as a neutron source—will be ready for another decade or more of service, with the potential for more experimental capacity in years to come.

The Department of Energy has announced up to $40 million in funding for a new Advanced Research Projects Agency-Energy (ARPA-E) program to conduct research and development into technologies for reprocessing and ultimately disposing of used nuclear fuel. The program, “Optimizing Nuclear Waste and Advanced Reactor Disposal Systems” (ONWARDS), announced on May 19, targets both open (once-through) and closed (reprocessing) fuel cycles to reduce the amount of waste produced from advanced reactors tenfold when compared to light water reactors.
