Now that the Department of Energy has approved Critical Decision 1 for the Versatile Test Reactor (VTR) project, the engineering design phase can begin once Congress appropriates funding, according to a September 23 announcement from the DOE’s Office of Nuclear Energy. The DOE has requested $295 million for the project in fiscal year 2021.
The news came nearly one month after a team led by Bechtel National Inc. (BNI), and including GE Hitachi Nuclear Energy (GEH) and TerraPower, entered into contract negotiations with Battelle Energy Alliance (BEA) for the design-and-build phase of the VTR. GEH’s sodium-cooled fast reactor PRISM technology was selected to support the VTR program in November 2018.
The Nuclear Regulatory Commission announced on September 21 that based on a review of 141 research and development grant proposals, it anticipates awarding more than $7.25 million in funding to 15 of the peer-reviewed proposals. The funding is part of the $16 million appropriated by Congress in fiscal year 2020 under the Integrated University Program.
While independent NRC review panels recommended the 15 R&D proposals for funding, the NRC’s Office of Nuclear Regulatory Research will make a final decision on the awards.
A virtual side event at the 64th General Conference of the International Atomic Energy Agency will spotlight U.S. reactor technologies. The free event, US Reactor Technologies: Flexible Energy Security for Real-World Challenges, will be held this Thursday, September 24, from 9:00 a.m. to 10:30 a.m. (EDT).
The event will highlight the capabilities of small modular reactors and other innovative reactors for addressing countries’ current needs. It will also examine anticipated challenges in the future, as well as underscore the need to act now.
The event is sponsored by the U.S. Department of Energy’s Office of Nuclear Energy. Advanced registration is required.
The board of directors of the Energy Communities Alliance (ECA), an organization known more for its work in advancing the cleanup of Department of Energy sites, is launching a new initiative aimed at supporting the development of new nuclear technologies. As announced by the ECA on September 15, the self-funded, one-year initiative will focus on small modular reactors, micro and advanced reactors, a skilled nuclear workforce, and new nuclear missions around DOE facilities. facilities.
“With growing bipartisan support for nuclear energy in Congress, new federal demonstration projects led by DOE and the Department of Defense, and notable investment from the private sector, local governments want to be meaningfully engaged—and prepared—to match the strengths and needs of our communities with new nuclear opportunities,” the ECA said in its announcement.

The Department of Energy on September 8 announced funding for research at the National Spherical Tokamak Experiment Upgrade (NSTX-U), an Office of Science user facility at the DOE’s Princeton Plasma Physics Laboratory in Princeton, N.J.
Total planned funding is $17 million for the NSTX-U work over five years in duration. As much as $6 million in fiscal year 2020 dollars and out-year funding could be available this year, contingent on congressional appropriations and satisfactory progress.
The initiative will support experiments, data analysis, and computer modeling and simulation of plasma behavior. A major focus will be on the start of laying the scientific groundwork for a next-generation facility through better understanding of the behavior of plasmas in spherical tokamaks, the DOE said.
Canadian Nuclear Laboratories (CNL) on September 3 announced a research collaboration agreement with Kairos Power. Funded through CNL’s Canadian Nuclear Research Initiative (CNRI), the agreement includes research and engineering for technologies to separate, analyze, and store the tritium that would be created during the operation of Kairos Power’s proposed fluoride-salt–cooled small modular reactor.
The Department of Energy announced on September 2 that it has issued $29 million in funding for 14 projects as part of its Galvanizing Advances in Market-aligned fusion for an Overabundance of Watts (GAMOW) program, which is jointly sponsored by the department’s Advanced Research Projects Agency–Energy (ARPA-E) and the Office of Science–Fusion Energy Sciences (SC-FES).
According to the DOE, GAMOW teams will work to close multiple fusion-specific technological gaps that will be needed to connect a net-energy-gain “fusion core,” once it is ready, to a deployable, commercially attractive fusion system.
Idaho National Laboratory’s Transient Reactor Test Facility, also known as TREAT, returned to service in 2017 after a hiatus of more than two decades. To make full use of TREAT’s capabilities, researchers at INL created the Minimal Activation Retrievable Capsule Holder (MARCH) test vehicle system, which, according to an August 26 Department of Energy press release, can cut years off the development process for nuclear fuels and materials and allow new clients, like NASA, to take advantage of TREAT’s capabilities.

A team led by Bechtel National Inc. (BNI) that includes GE Hitachi Nuclear Energy (GEH) and TerraPower is in contract negotiations with Battelle Energy Alliance (BEA) for the design-and-build phase of the Versatile Test Reactor, BEA announced on August 24. As planned, the VTR would support irradiation testing of fuels, materials, and equipment designed for advanced reactors.
The Department of Energy on August 19 announced several awards to research teams applying artificial intelligence and machine learning to fusion energy. The planned total funding of $21 million is targeted at projects with time frames of up to three years; $8 million in fiscal year 2020 funding has already been committed to the work. Delivery of the balance-of-project funding will depend on future congressional appropriations.
“These awards will enable fusion researchers to take advantage of recent rapid advances in artificial intelligence and machine learning,” said Chris Fall, director of the DOE’s Office of Science. “AI and ML will help us to accelerate progress in fusion and keep American scientists at the forefront of fusion research.”

Every year, Lawrence Livermore National Laboratory releases flowcharts illustrating U.S. energy consumption and use. The flowcharts, called Sankey diagrams, allow scientists, analysts, and other decision makers to compare the contributions made by various energy sources, including nuclear power, and the end uses of those sources, including residential, industrial, commercial, and transportation markets. Taken as a series of annual snapshots, energy use trends and opportunities quickly become apparent.
This year, in addition to releasing the 2019 energy flowchart, the lab issued state-by-state energy flowcharts for 2015–2018 and carbon emissions charts for 2014–2017. It is currently at work on charts of international energy use that it hopes to release by the end of the year.
Fuel compact cross section showing dozens of individual TRISO particles.
Tristructural isotropic (TRISO) coated particle fuel is a robust, microencapsulated fuel form developed originally for use in high-temperature gas-cooled reactors (HTGRs). The particles consist of a spherical fissile kernel surrounded by several layers of pyrocarbon and a silicon carbide (SiC) layer. The particles are formed into cylindrical or spherical fuel forms using a resinated graphite matrix material for insertion into an HTGR. The kernel and coating layers together act to retain fission products within the particle during normal reactor operation and during postulated accidents; TRISO particles can maintain structural integrity at extremely high temperatures, reaching as high as approximately 1,600 °C in limiting HTGR accidents. This limits the fission product activity circulating in the helium coolant and the activity released to the environment during accidents. Acceptable performance of TRISO particles is therefore essential for reactor safety.

Abilene Christian University (ACU) is leading a consortium called NEXTRA—the Nuclear Energy eXperimental Testing Research Alliance—with the Georgia Institute of Technology, Texas A&M University, and the University of Texas at Austin. NEXTRA was formed in spring 2019 to design, license, and commission a molten salt–fueled research reactor to be hosted on ACU’s campus in the central Texas city of Abilene. ACU and its partners recently announced funding of $30.5 million over the next three years from Abilene-based Natura Resources.
The Department of Energy is asking for input on an Energy Storage Grand Challenge (ESGC) Draft Roadmap and Request for Information (RFI) and recently extended the response deadline to August 31. While there is no “N” for nuclear in “ESGC,” nuclear is definitely part of the DOE’s plan for future energy storage technologies and integrated energy systems designed to improve the efficiency and reliability of U.S. energy markets. In fact, the House Energy and Water Appropriations Committee has called for $4 million in the Office of Nuclear Energy’s Fiscal Year 2021 budget to support energy storage.
With the Democratic Convention now under way, it is good to remember that all the leading climate scientists say that we cannot address climate change without significant nuclear power, Jim Conca noted in his opinion column on the Forbes blog site. Supporting nuclear power - or not - is a clear signal about how serious a candidate is about climate change and supporting science over mere activism, Conca said.
