In this illustration of the effects of two neutron yields (50 kt and 1 Mt) and two neutron energies (14.1 MeV and 1 MeV), the black dots represent the location of a nuclear device. Dark blue indicates where the asteroid remains solid, while all other colors show where material has been melted or vaporized. The illustration depicts asteroids with 0.8-m and 5-m diameters—much smaller than the 300-m asteroid simulated in the study—to enhance the visibility of the area of the energy deposition.

A research collaboration between Lawrence Livermore National Laboratory and the Air Force Institute of Technology (AFIT) has investigated how the neutron energy generated by the detonation of a nuclear device could affect the path and speed of an asteroid on a collision course with Earth by melting and vaporizing a portion of the asteroid. The research, which compared the deflection caused by two different neutron energies—14.1 MeV and 1 MeV, representing fusion and fission neutrons, respectively—is described in an article published by LLNL on April 8.

Scientists at the DIII-D National Fusion Facility have published research on a compact fusion reactor design they say could be used to develop a pilot-scale fusion power plant. According to General Atomics (GA), which operates DIII-D as a national user facility for the Department of Energy’s Office of Science, the Compact Advanced Tokamak (CAT) concept uses a self-sustaining configuration that can hold energy more efficiently than in typical pulsed configurations, allowing the plant to be built at a reduced scale and cost.

A bright future ahead for nuclear engineering students

Happy spring to you, my nuclear comrades. As I write this column (in early March), I’m glancing out the window at the 10 inches of snow still remaining in my backyard. By the time you read this, the snow may be gone, and spring flowers may be poking out of the earth. Every year, I look forward to gardening season, which is short but fun in Idaho.

Over the past year, unfortunately, many of the things we looked forward to didn’t happen. Hardest hit, of course, were the people who fell ill with COVID-­19 and those who lost jobs. But in the “disappointed” category, our students were especially vulnerable. Elementary school students, who most need face-­to-­face contact with their teachers, were isolated at home. Adolescents and teens had no dances, football games, or lunchtimes with their friends. High school and college seniors couldn’t celebrate graduation. University freshmen, who already cope with significant change and stress, added to their agendas the threat of a global pandemic and the complication of distance learning.

Research led by scientists at the Department of Energy's Princeton Plasma Physics Laboratory (PPPL) provides new evidence that particles of boron, the main ingredient in Borax household cleaner, can coat internal components of doughnut-shaped plasma devices known as tokamaks and improve the efficiency of the fusion reactions, according to an article published on on April 2.

With first plasma operations at ITER planned for 2025, milestones are being reached in quick succession. While several of the 35 countries contributing to the construction of the super-sized fusion tokamak are pursuing fusion programs of their own, they remain committed to ITER and are eager for the data and operating experience it is expected to yield.

Euratom leads the project being built in Cadarache, France, as the host party for ITER. On February 22, the European Council approved the continuation of European financing of ITER from 2021 to 2027, with a contribution of €5.61 billion (about $6.86 billion) in current prices.

A new goal for fusion: 50 MWe for the U.S. grid by 2035–2040

February 19, 2021, 7:00AMNuclear News

Coordinated federal and private industry investments made now could yield an operational fusion pilot plant in the 2035–2040 time frame, according to Bringing Fusion to the U.S. Grid, a consensus study report released February 17 by the National Academies of Sciences, Engineering, and Medicine (NASEM).

Developed at the request of the Department of Energy, the report builds on the work of the 2019 Final Report of the Committee on a Strategic Plan for U.S. Burning Plasma Research, and it identifies key goals, innovations, and investments needed to develop a U.S. fusion pilot plant that can serve as a model for producing electricity at the lowest possible capital cost.

“The U.S. fusion community has been a pioneer of fusion research since its inception and now has the opportunity to bring fusion to the marketplace,” said Richard Hawryluk, associate director for fusion at the Princeton Plasma Physics Laboratory and chair of the NASEM Committee on the Key Goals and Innovations Needed for a U.S. Fusion Pilot Plant, which produced the report.

The fusion community is reaching a "Kitty Hawk moment" as early as 2025, according to the Popular Mechanics story, "Jeff Bezos Is Backing an Ancient Kind of Nuclear Fusion."

That moment will come from magnetized target fusion (MTF), the January 25 story notes, a technology that dates back to the 1970s when the U.S. Naval Research Laboratory first proposed it. Now, however, MTF’s proponents say that the technology is bearing down to reach the commercial power market. The question is, Will it be viable before the competing fusion model of tokamaks, such as ITER, start operations?

The promise of hydrogen fusion as a safe, environmentally friendly, and virtually unlimited source of energy has motivated scientists and engineers for decades. For the general public, the pace of fusion research and development may at times appear to be slow. But for those on the inside, who understand both the technological challenges involved and the transformative impact that fusion can bring to human society in terms of the security of the long-term world energy supply, the extended investment is well worth it.

Failure is not an option.
