U.S. fusion pilot program ready to back designs from industry-led teams

September 27, 2022, 7:00AMNuclear News

The Department of Energy announced up to $50 million for a new milestone-based fusion energy development program on September 22. The funding opportunity announcement is open to for-profit companies—possibly teamed with national laboratories, universities, and others—that are prepared to meet major technical and commercialization milestones leading to a pilot fusion power plant design.

NASEM report: U.S. low-dose radiation research needs DOE/NIH leadership

June 3, 2022, 9:29AMNuclear News

A new report from the National Academies of Sciences, Engineering, and Medicine (NASEM) estimates that $100 million annually will be required for the next 15 years to develop a coordinated research program led by the Department of Energy and the National Institutes of Health to study how low doses of radiation affect disease risk. The recommended research would investigate causal links to specific health conditions and better define the impacts of radiation doses, dose rates, types of radiation, and exposure duration.

Nuclear propulsion on the rise as private companies and NASA redefine space travel

In July 1969, the public’s attention was fixated on NASA’s Apollo 11 mission—a “giant leap for mankind” that was memorably marked by Neil Armstrong as he stepped onto the surface of the moon. This July, the possibilities of spaceflight are once again capturing the public’s imagination and news headlines. While NASA invests in nuclear propulsion research and development to stretch the limits of U.S. space missions, private companies Virgin Galactic and Blue Origin are stretching the definition of “astronaut” and proving they can offer a high-altitude thrill to paying customers.

Planning ahead for advanced reactor safeguards and security

Nonproliferation, safeguards, and security were on the agenda for the fifth public information-gathering meeting of the National Academies’ Committee on Merits and Viability of Different Nuclear Fuel Cycles and Technology Options and the Waste Aspects of Advanced Nuclear Reactors. Moderated by committee chair Janice Dunn Lee and NAS study director Charles Ferguson, the two-day public meeting was convened on May 17 and was to be followed by a closed committee session on May 19.

As Perseverance makes tracks, NASA must plan its next Mars move

March 10, 2021, 3:00PMNuclear News

NASA’s Mars 2020 Perseverance rover took its first drive on the surface of Mars on March 4, traversing 21.3 feet and executing a 150-degree turn in about 33 minutes. The drive was one part of an ongoing check and calibration of every system, subsystem, and instrument on Perseverance, which landed on Mars on February 18.

The NASA team has also verified the functionality of Perseverance’s instruments, deployed two wind sensors, and unstowed the rover’s 7-foot-long robotic arm for the first time, flexing each of its five joints over the course of two hours.

With relatively little fanfare, the functionality of Perseverance’s radioisotope thermoelectric generator (RTG)—assembled at Idaho National Laboratory and fueled by the decay of plutonium-238—is also being proved. It is reliably providing the power that Perseverance’s mechanical and communication systems require.
