On August 2, 1946, 1 millicurie of the isotope carbon-14 left Oak Ridge National Laboratory, bound for the Barnard Free Skin and Cancer Hospital in St. Louis, Mo.

That tiny amount of the radioisotope was purchased by the hospital for use in cancer studies. And it heralded a new peacetime mission for ORNL, built just a few years earlier for the production of plutonium from uranium for the Manhattan Project.

“The tools of the academic designer are a piece of paper and a pencil with an eraser. If a mistake is made, it can always be erased and changed. If the practical-reactor designer errs, he wears the mistake around his neck; it cannot be erased. Everyone sees it.”

Many in the nuclear community are familiar with this sentiment from Admiral Rickover. A generation of stagnation in the industry has underscored the truth of his words. But as economies around the world put a price on carbon emissions, there’s a renewed sense of urgency to deploy clean energy technologies. This shifts the global balance of economic competitiveness, and it’s clear that the best path forward for nuclear requires combining the agility of private innovators with the technology and capabilities of national laboratories.

Gas-cooled reactors have roots that reach way back to the development of early experimental reactors in the United States and Europe. In the United States, early experimental reactors at Oak Ridge and Brookhaven National Laboratories were air-cooled, as were early production reactors known as the “Windscale Piles” in the United Kingdom. Dragon, also located in the United Kingdon and operational from 1965 to 1976, used helium as the coolant and graphite as the moderator.

Fusion energy radwaste management considerations

December 2, 2022, 3:00PMNuclear NewsLaila El-Guebaly

The question of what to do with the radioactive waste has been raised frequently for both fission and fusion. In the 1970s, fusion adopted the land-based disposal option, primarily based on the Nuclear Regulatory Commission’s decision to regulate all radioactive wastes as only a disposal issue, following the fission guidelines. In the early 2000s, members of the Advanced Research Innovation and Evaluation Study (ARIES) national team became increasingly aware of the high amount of mildly radioactive materials that 1-GWe fusion power plants will generate, compared with the current line of fission reactors. The main concern is that such a sizable inventory of mostly tritiated radioactive materials would tend to rapidly fill U.S. repositories—a serious issue that was overlooked in early fusion studies1 that could influence the public acceptability of fusion energy and will certainly become more significant in the immediate future if left unaddressed, as fusion moves toward commercialization.

Delivery of electricity from fusion is considered by the National Academies of Engineering to be one of the grand challenges of the 21st century. The tremendous progress in fusion science and technology is underpinning efforts by nuclear experts and advocates to tackle many of the key challenges that must be addressed to construct a fusion pilot plant and make practical fusion possible.

In his annual State of the State Address on January 31, Tennessee Gov. Bill Lee offered more praise for nuclear energy, after lauding it earlier in the month during a tour of the Tennessee Valley Authority’s Watts Bar nuclear plant

“For decades, East Tennessee has been home to some of the best-kept secrets in nuclear energy and American innovation,” Lee told the state’s General Assembly. “Today, many may not realize that Tennessee derives more power from nuclear energy than from any other source. Recently, I visited the TVA’s Watts Bar nuclear facility, the last nuclear facility to be built in America, to see firsthand how nuclear power keeps our grid dependable even when the weather is not. Nuclear power is clean energy that actually works for the private sector.”
