ANS Winter Meeting: What it will take to “Fuel our Nuclear Future"
The 2021 ANS Winter Meeting and Technology Expo began this morning with a Opening Plenary Session chaired by Winter Meeting general chair Amir Vexler, president and chief executive officer of Orano USA. It was an opportunity to both celebrate achievements that are already building a “Nuclear Future” and to identify needs and challenges ahead.
Influential speakers from the U.S. Congress, the Department of Energy, and the Nuclear Energy Institute joined ANS president Steven Nesbit and ANS CEO/executive director Craig Piercy to explore key issues associated with the front end of the nuclear fuel cycle, including supply and demand for high-assay, low-enriched uranium (HALEU). They didn’t stop there, however. They took questions from an in-person and virtual audience that probed other requirements of a sustainable nuclear future, including fueling a human resources pipeline.

The release behavior of radioactive materials from high active liquid waste (HALW) has been investigated under boiling accident conditions. Results of the experiment using a nonradioactive simulated HALW found Ru to be a volatile element under the accident conditions and to be released into the gas phase in the form of both mist and gas. The Ru release rate and the apparent Ru volatilization rate constant were obtained under the boiling conditions of simulated HALW. The other fission product elements such as Cs were found to be nonvolatile and to be released into the gas phase in the form of mist. The mist size distribution near the surface of the simulated HALW in the reactor vessel was found to range from 0.05 to 20 μm with a peak diameter of ∼2 μm.
