We welcome ANS members with long careers in the community to submit their own stories so that the personal history of nuclear power can be captured. For information on submitting your stories, contact nucnews@ans.org.

I was born and raised in Pittsburgh, Pa. In 1959, I received my Ph.D. in experimental nuclear physics utilizing the 400-MeV synchrocyclotron at Carnegie Mellon University, involving measuring the scattering of pi-­mesons from protons (as a liquid hydrogen target). I joined ANS in January 1960.

I later joined General Electric’s Aircraft Nuclear Propulsion project to build a nuclear jet engine at the National Reactor Testing Station at Idaho Falls (now Idaho National Laboratory). In January 1961, the U.S. Army’s experimental nuclear reactor SL-1 blew up, killing three army personnel. At first, the Air Force would not permit General Electric to take part in the cleanup, but after the Aircraft Nuclear Propulsion project was canceled by President Kennedy in March, GE took on the SL-1 disassembly and analysis project. I oversaw the analysis, which took nearly two years.

Remembering William A. Anders

William A. Anders

William A. Anders, former chairman of the Nuclear Regulatory Commission and a former member of the American Nuclear Society, died on June 7 at 90 years of age.

In a June 18 statement, the NRC offered condolences on his passing.

“Chairman Anders had an illustrious career far beyond taking one of the most widely seen photos from space,” said NRC chair Christopher Hanson. “He was the only person to serve as commissioner on both the Atomic Energy Commission and NRC, and he served as the new agency’s first chairman, providing institutional continuity while unambiguously committing the agency to serve as an unbiased, independent, and open regulator. We are saddened by his death and extend our condolences to his family.”

Europe’s first Mars rover—named Rosalind Franklin—was months away from a planned September launch when the European Space Agency (ESA) convened a meeting a few weeks after Russia’s February 2022 invasion of Ukraine. The ESA Council unanimously agreed on “the present impossibility” of working with Roscosmos as its launch partner and later decided to reboot its ExoMars mission with a new lander, new partners, and a new launch date.

In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

How can the nuclear community support space applications?

The most important thing the nuclear community can do to support space nuclear applications is the same thing we must focus on for terrestrial nuclear science: developing the trust of the American public.

Americans are widely supportive of NASA, and space has long captivated our imaginations. Recently, the publicity surrounding the new U.S. Space Force and the popularity of commercial rocket launches have drawn the public eye skyward. We don’t need to convince people that space is important and exciting, but we do have a long way to go in promoting nuclear power to the public.


Radiant horizons: Fission surface power on the moon, Mars, and beyond

Imagine what our world would be like today without the benefits of electric energy. Think of the inventions and technologies that never would have been. Think of a world without power grids and the electricity that makes them run. Without this power, we’d find it difficult to maintain our industrial and manufacturing bases or enable advancements in the fields of medicine, communications, and computing.

Now consider the moon, our closest celestial neighbor about which we still know so little, waiting for modern-day explorers in spacesuits to unveil its secrets. Lunar exploration and a future lunar economy require reliable, long-lasting, clean sources of power. Nuclear fission answers that call. When assessing the application of nuclear power in space, three Ps should be considered: the present, the potential, and the partnerships.

Nations envision nuclear reactors on the moon

Borisov

Russian space agency Roscosmos has announced its intention to build a nuclear reactor on the lunar surface in collaboration with the China National Space Administration. According to Roscosmos director general Yury Borisov, “Today we are seriously considering a project—somewhere at the turn of 2033–2035—to deliver and install a [nuclear] power unit on the lunar surface together with our Chinese colleagues.” The reactor would apparently be used to supply power to the Russian-Chinese International Lunar Research Station (ILRS), plans for which the two nations unveiled in 2021.

These plans come on top of previously announced plans of the United States and United Kingdom for lunar nuclear reactors.

A big thank-you to the American Nuclear Society Young Members Group for all it accomplished at the Young Professionals Congress (YPC) and President’s Special Session at the 2023 ANS Winter Conference and Expo.

The YPC was held on Saturday, November 11. Its chair, Miriam Kreher, and the YPC planning committee did an excellent job organizing and executing the congress. Its three tracks had something for everyone, including knowledge expansion and soft skills training. The speakers at the congress, including Katy Huff, assistant secretary for nuclear energy, were outstanding in every category.

The President’s Special Session was organized by the Young Members Group (YMG). Matt Wargon, YMG chair, and the planning committee did an incredible job. We kicked around several ideas for a theme before landing on “Space: The [Next] Nuclear Frontier.”

New modeling of nuclear device to deflect or destroy asteroids en route to Earth

The same high energy density that makes nuclear energy a clean and efficient source of power could make it a good alternative to defend the planet against catastrophic asteroid impacts. NASA demonstrated the world’s first planetary defense technology in September 2022 by deliberately crashing a “kinetic impactor”—a heavy, box-like spacecraft—into an asteroid. Now, researchers at Lawrence Livermore National Laboratory have developed a new tool to model how a nuclear device could deflect—or even destroy—an asteroid threat to Earth in a more efficient and controlled way.

Investments for peace

President Dwight D. Eisenhower delivered his “Atoms for Peace” speech to the United Nations General Assembly in December 1953. In this historic address, he invoked the existential threat of nuclear weapons proliferation and the potential horror of nuclear war to muster the diplomatic energy of the United Nations toward establishing peaceful uses for the atom. The speech launched domestic and international initiatives, including the International Atomic Energy Agency, that would underpin decades of robust, peaceful nuclear power commercialization and expansion.

This month, as we celebrate the 70th anniversary of that speech, we celebrate Eisenhower’s prescience in suggesting that “experts would be mobilized to apply atomic energy to the needs of agriculture, medicine, and other peaceful activities” and “to provide abundant electrical energy in the power-starved areas of the world.” Mobilizing American experts, of course, would mean refocusing the work of the national laboratories toward peaceful uses of the atom and repurposing the vast weapons complex investments of the 1940s toward more peaceful ends.

ANS Winter Meeting: Space—the next nuclear frontier

November 15, 2023, 12:00PMNuclear News

Put nuclear technology in space or on the moon, and just as on Earth it can provide a power density unmatched by any other source. But what roles can nuclear power and propulsion play as the world enters a 21st-century space race? That was a key question put to six speakers during the November 14 American Nuclear Society Winter Meeting plenary session “Space: The (Next) Nuclear Frontier.”

Leading DRACO to launch: An interview with DARPA’s Tabitha Dodson

July 28, 2023, 2:59PMNuclear NewsSusan Gallier

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.
