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.

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

The horizontal rotary glow discharge polymer (GDP) coater is being developed to help increase the production rate of inertial confinement fusion targets and to meet the very high production rates needed for inertial fusion energy targets. The coater is used to put a conformal GDP gas retention coating on top of foam shell targets. A number of alterations to the design and operation of the horizontal rotary GDP coater are discussed. Compared to previous iterations of the horizontal coater, the changes have resulted in improving the yield of gas retentive targets with thinner coatings and increasing the coating rate, smoothness, and uniformity. The number of targets that can be coated at once has increased from tens to hundreds, or even thousands. The alterations include changing the coating tube configuration; adjusting the coating pressures; and altering the radio-frequency power, gas flow rates, and tube rotation rates. Methods to further improve the coater are also discussed.
