Sometimes, even with decades of research and testing, a project never gets off the ground. That has been the case for U.S. nuclear thermal rockets—so far. Research began in the 1950s and peaked with a series of rigorous ground tests for NERVA—the Nuclear Engine for Rocket Vehicle Applications—before the program was canceled in 1973. Five decades on, this technology has yet to make it to the launchpad. But while mission priorities shift, the physics is solid: Fission-powered nuclear thermal rockets (NTRs) still offer two to five times greater efficiency than conventional rockets.

In an 86–11 vote yesterday, the Senate passed the fiscal year 2024 National Defense Authorization Act (NDAA), and with it, the Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy (ADVANCE) Act.

Introduced March 30 by the senatorial trio of Shelley Moore Capito (R., W.Va.), Tom Carper (D., Del.), and Sheldon Whitehouse (D., R.I.), The ADVANCE Act was endorsed by the Environment and Public Works Committee in May in a bipartisan 16–3 vote and was made part of the annual must-pass NDAA earlier this month.

On July 14, the House narrowly passed (219–210) its own version of the NDAA, containing several controversial amendments pushed by GOP conservatives. The two chambers are now faced with reconciling the two measures and producing a compromise version that can be sent to President Biden’s desk.

Through its now one-year-old Nuclear Fuel Fund, the U.K. government has awarded Westinghouse three grants to upgrade and expand the Springfields Fuel Fabrication Facility to support Britain’s next-generation nuclear reactors, the American-based company announced yesterday.

The Department of Energy is providing $4.6 million in funding for 18 projects at national laboratories and U.S. universities to help address critical scientific and technological challenges in pursuing fusion energy systems.

The nuclear industry’s first 100 percent accident tolerant fuel assembly has successfully completed its initial cycle of operation at a U.S. nuclear power plant, Framatome announced earlier this week.

Following 24 months of operation at Constellation Energy’s two-unit Calvert Cliffs nuclear power plant in Lusby, Md., testing and inspections confirm that Framatome’s lead Enhanced Accident Tolerant Fuel (EATF) assembly safely withstood in-reactor conditions and performed as designed, according to the French-based company.

"The accelerated delivery and proven performance of our technology reflects the dedication and expertise of our people with the collaborative support from the industry,” said Lionel Gaiffe, senior executive vice president of Framatome’s fuel business unit. “Collectively, we are one step closer in the qualification of our Protect EATF technology for the nuclear industry. With the adoption and implementation of our enhanced technologies, our industry partners continue to demonstrate their commitment to enhance the safety and performance of their reliable, low-carbon, energy operations.”

I am lucky. I live near a nuclear power plant—arguably the best run and most beautiful power plant in the world. It’s comforting.

It’s comforting to see Columbia Generating Station’s clean white plume of pure steam rise into the air every time I leave my house. Every time I’m driving home. Every time it’s freezing outside. Every time it’s scorching hot.

Even the few times when it has gone quiet for refueling, the plant stands like a Norman castle protecting the region from energy poverty. It’s comforting.

The Massachusetts Institute of Technology and the Clean Air Task Force are offering a three-day course “Nuclear Energy in a Low-Carbon Future: Key Facts and Issues” on August 1–3. The course is organized by MIT’s Jacopo Buongiorno, Tokyo Electric Power Company Professor in Nuclear Engineering and director of science and technology for the university’s Nuclear Reactor Laboratory.

The daily schedule runs from 9:00 a.m.–5:00 p.m. (Eastern) on the first two days and 9:00 a.m.–12:30 p.m. on the third day.

The in-person version of the course is fully booked, but slots for remote attendance are still available—at no cost. Registration is required by completing a registration form.

NASA has selected 11 companies, including Zeno Power, to develop technologies that could support long-term exploration on the moon and in space. The technologies range from lunar surface power systems to tools for in-space 3D printing, which will expand industry capabilities for a sustained human presence on the moon through the Artemis program, as well as other NASA, government, and commercial missions.

BWX Technologies announced today that it has been selected to supply the nuclear reactor and fuel for the Defense Advanced Research Projects Agency’s Demonstration Rocket for Agile Cislunar Operations (DRACO) program—the goal of which is to demonstrate a nuclear thermal propulsion (NTP) engine in orbit.

Kairos Power has filed a construction permit application with the Nuclear Regulatory Commission for a two-unit version of its Hermes advanced test reactor.

The Department of Energy is planning to ship contaminated process equipment from its Savannah River Site in South Carolina to Waste Control Specialists’ federal low-level radioactive waste facility in Andrews County, Texas.

The Department of Energy is holding an initial Industry Day on July 28 that is open to parties with proven experience in implementing successful clean electricity projects generating 200 MW or larger.

During a walkdown at Ukraine’s Zaporizhzhia nuclear power plant on July 23, a team of International Atomic Energy Agency experts reported seeing “some” directional antipersonnel mines in a buffer zone between the Russian-occupied site’s internal and external perimeter barriers, the agency announced yesterday.

Westinghouse Electric Company welcomed 95 vendors to the Canadian Supplier Symposium last week to engage with current and potential suppliers for the company’s global new-build projects.

Robert P. Martin and Thomas E. Roberts have been appointed to four-year terms on the Advisory Committee on Reactor Safeguards, the Nuclear Regulatory Commission announced on July 20.

The Japanese government has chosen Mitsubishi Heavy Industries (MHI) to head up the conceptual design and research and development of a demonstration sodium-cooled fast reactor, the Tokyo-based engineering firm announced recently.

MHI is to oversee the work in partnership with Mitsubishi FBR Systems Inc. (MFBR), an MHI Group engineering company established in 2007 to develop and design fast breeder reactors.

Conceptual design work is scheduled to commence in fiscal year 2024, with operation of the unit slated for the 2040s.

Reactor roadmap: According to MHI’s announcement, in the strategic roadmap for fast-reactor development adopted by the Japanese Cabinet in December 2018, a policy was defined to assess the efficacy of several types of technologies to be developed following a competition among private-sector companies. The roadmap was subsequently revised by the Cabinet in December 2022, at which time two decisions were made: (1) to select a sodium-cooled fast reactor as the target of the conceptual design of the demonstration unit and (2) to select a manufacturer to serve as the core company in charge of the reactor’s design and requisite R&D.

The Spallation Neutron Source (SNS) at the Department of Energy's Oak Ridge National Laboratory set a world record when its particle accelerator beam operating power reached 1.7 MW, an improvement on the facility’s original design capability of 1.4 MW, ORNL announced on July 21. That higher power provides more neutrons for researchers who use the Office of Science user facility for materials science investigations.

The U.S. Nuclear Regulatory Commission and the Ghana Nuclear Regulatory Authority reaffirmed last week its shared commitment to continue cooperation on nuclear safety and regulation for the African nation.

Southern Nuclear, operator of Georgia’s Vogtle plant, has informed the Nuclear Regulatory Commission that all 364 inspections, tests, and analyses for Unit 4 have been performed, and all acceptance criteria for the new reactor have been met. Primary plant owner Georgia Power made the announcement last Friday.

The Department of Energy’s National Nuclear Security Administration (NNSA) announced on July 20 that it has awarded two organizations—Hardinge Inc. and the Association of Journeyman and Apprentices of the Plumbing and Pipefitting Local 412—five-year grants totaling $2.17 million. The funds will be used to develop and strengthen apprenticeship training programs aligned with the NNSA’s needs for technician positions throughout its laboratories, plants, and sites.
