ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.
Meeting Spotlight
Nuclear Energy Conference & Expo (NECX)

Take steps on SNF and HLW disposal
Matt Bowen
With a new administration and Congress, it is time once again to ponder what will happen—if anything—on U.S. spent nuclear fuel and high-level waste management policy over the next few years. One element of the forthcoming discussion seems clear: The executive and legislative branches are eager to talk about recycling commercial SNF. Whatever the merits of doing so, it does not obviate the need for one or more facilities for disposal of remaining long-lived radionuclides. For that reason, making progress on U.S. disposal capabilities remains urgent, lest the associated radionuclide inventories simply be left for future generations to deal with.
In March, Rick Perry, who was secretary of energy during President Trump’s first administration, observed that during his tenure at the Department of Energy it became clear to him that any plan to move SNF “required some practical consent of the receiving state and local community.”1

We describe a high pressure cryogenic fill station and a novel method to retrieve and transport filled inertial confinement fusion targets at cryogenic temperatures. The fill station (currently under construction) will be capable of filling millimeter-size plastic spheres with DT or D2 to pressures exceeding 150 MPa. After filling, the thin-walled targets are cooled and kept below 20 K to prevent them from bursting. After cooling the targets, a cryogenic wrench is used to open the pressurization cell. The fill station cryostat is designed to allow a second cryostat to retrieve the filled targets. This second cold transfer cryostat features removable shrouds with seals that can be repeatably made and broken at cryogenic temperatures.
