The Nuclear Regulatory Commission has authorized the restart of a test reactor at the National Institute of Standards and Technology, in Gaithersburg, Md. The reactor was shut down in February 2021 when a fuel element became damaged during startup and approach to full power. The incident violated the NRC’s fuel cladding temperature safety limit, although public health and safety were not affected, according to the agency.

The reactor is located at NIST’s Center for Neutron Research.

The Spallation Neutron Source (SNS) at the Department of Energy's Oak Ridge National Laboratory set a world record for accelerator-driven neutron research when its linear accelerator reached an operating power of 1.55 MW, improving on the facility’s original design capability of 1.4 MW. That higher power means more neutrons for researchers who use the facility for neutron scattering research to reach materials science advances, ORNL announced recently.

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 Nuclear Regulatory Commission has issued its final safety evaluation report (SER) related to the operating license application for SHINE Technologies' large-scale medical isotope production facility, known as The Chrysalis, in Janesville, Wis. The SER documents the results of NRC staff’s technical and safety review of SHINE’s application. SHINE announced the NRC’s decision on February 27.

A record of decision concerning the proposed issuance of the operating license will be published by the NRC at a future date.

The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $10 million in funding on February 17 for eight projects designed to determine whether low-energy nuclear reactions (LENR)—historically and sometimes disparagingly known as “cold fusion”—could someday be a carbon-free energy source. ARPA-E intends the funding to “break the stalemate” and determine if LENR holds any merit for future energy research.

Commonwealth Fusion Systems (CFS) hosted visiting officials for a tour and ribbon-cutting ceremony to officially open its new headquarters in Devens, Mass., on February 10. Energy secretary Jennifer Granholm, Sen. Elizabeth Warren (D., Mass.), and Sen. Edward Markey (D., Mass.) were among the national, state, and local leaders invited to celebrate what CFS heralded as a “fusion energy campus.”

A key component needed for the National Spherical Torus Experiment–Upgrade (NSTX-U), the flagship fusion facility currently under repair at the Department of Energy’s Princeton Plasma Physics Laboratory (PPPL), has been delivered to the lab’s New Jersey campus.

The Nuclear Regulatory Commission has issued the final supplemental environmental impact statement (EIS) for SHINE Technology’s application for a license to operate a medical isotope production facility in Janesville, Wis.

Tokamak Energy announced on February 6 that it has built a world-first set of high-temperature superconducting (HTS) magnets, to be assembled and tested in fusion power plant–relevant scenarios.

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.

Ignition and net gain at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) in December 2022 focused global attention on the prospects of inertial fusion energy (IFE). First Light Fusion and the U.K. Atomic Energy Authority (UKAEA) acknowledged the achievement as they announced plans on January 25 to design and build a demonstration facility known as Machine 4 at UKAEA’s Culham Campus in Oxford, U.K., using First Light’s “projectile approach” to IFE. Construction is expected to begin in 2024, and operations are “likely to commence” in 2027.

The Department of Energy’s commitment to breaking down market barriers with initiatives, programs, and access to facilities is making it simpler and more efficient than ever for industry to partner with national laboratories. It is especially timely, as the country continues to face evolving security, economic, and clean energy challenges. Partnering opportunities via the DOE’s Cooperative Research and Development Agreements (CRADAs) and Strategic Partnership Projects (SPPs) are particularly prevalent in the commercial nuclear community and have seen a tremendous amount of funding and support dedicated to advancing the development, demonstration, and deployment of new reactor technologies.

NASA and the Defense Advanced Research Projects Agency (DARPA) have announced they will collaborate on plans to launch and test DARPA’s Demonstration Rocket for Agile Cislunar Operations (DRACO). DARPA has already worked with private companies on the baseline design for a fission reactor and rocket engine—and the spacecraft that will serve as an in-orbit test stand—and has solicited proposals for the next phase of work. Now NASA is climbing on board, deepening its existing ties to DRACO’s work in nuclear thermal propulsion (NTP) technology—an “enabling capability” required for NASA to meet its Moon to Mars Objectives and send crewed missions to Mars. NASA and DARPA representatives announced the development at the American Institute of Aeronautics and Astronautics SciTech Forum in National Harbor, Md., on January 24.

The Nuclear Innovation Alliance (NIA) released a new report last week titled Transforming the U.S. Department of Energy: Paving the Way to Commercialize Advanced Nuclear Energy, which gives recommendations for how the Department of Energy (DOE) can help advanced nuclear power technologies cross the finish line to commercialization. It calls for a “whole-of-government and whole-of-society effort dependent on successful public-private partnerships.”

The NIA report acknowledges that boosting energy security and meeting decarbonization goals will require at least double the domestic nuclear energy capacity that is on line today. But the nuclear industry is highly complex, and its supply chain is atrophied. The success of advanced nuclear technology will depend on careful collaboration and planning to bolster a new supply chain.

“Star Power” is the name 60 Minutes producers gave their interpretation of the recent experiment at the National Ignition Facility (NIF) that achieved fusion ignition and net gain. Views from inside Lawrence Livermore National Laboratory captured by TV cameras and aired Sunday, January 15—of some of NIF’s 192 lasers, banks of capacitors, target assembly labs, and even the remains of the target assembly blasted in the December 5 breakthrough—are well worth the watch for those of us who are unlikely to visit the site in person.

The use of small modular reactors would be an excellent, cost-effective way to recharge electric heavy-duty vehicles (HDVs), such as trucks, according to a recent study published in Applied Energy. The Idaho National Laboratory–funded study was conducted by researchers at the University of Michigan.

A “resurgence of interest” in nuclear propulsion for space missions is described in a new article authored by science writer Jon Kelvey for the American Institute of Aeronautics and Astronautics’ (AIAA’s) Aerospace America website. The focus of Kelvey’s article is nuclear thermal propulsion (NTP), which, according to the Department of Energy, “could significantly reduce travel times and carry greater payloads than today’s top chemical rockets­—giving humans a great chance of exploring deep space.”

The Department of Energy’s Office of Science announced $2.3 million in funding on January 17 for 10 fusion energy projects that will allow private companies to work with national laboratories to address specific challenges in fusion energy development. Seven private companies and seven national laboratories are represented in the 10 projects selected for funding, provided through the INFUSE (Innovation Network for Fusion Energy) program. The second-round fiscal year 2022 awards follow a first round of 18 project awards announced in July 2022.

Researchers at Idaho National Laboratory have completed initial testing on a newly developed fuel test capsule that is expected to provide crucial performance data for sodium-cooled fast reactors. The Department of Energy announced on January 12 that the series of fuel testing experiments being carried out now at INL’s Transient Reactor Test Facility (TREAT) was developed through a joint project between the United States and Japan.

The U.K. Atomic Energy Authority (UKAEA) announced on January 12 that the South Oxfordshire District Council Planning Committee approved a planned fusion energy demonstration project at UKAEA’s Culham Campus. UKAEA and General Fusion, the magnetized target fusion company that designed the demo plant, announced that same day that construction will begin this summer, with commissioning planned for 2026 and full operations by early 2027.
