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.

College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

Early shots on the National Ignition Facility (NIF) were plagued by the buildup of a considerable mass of extraneous ice on the laser entry hole (LEH) windows, a consequence of condensation of the residual air. This resulted in higher than desired temperatures at the LEH, which combined with the variability of the ice thickness made this a problem that needed a robust solution. In this paper, we describe our work in designing a second thin film that shielded the LEH window from the contaminating ice. The detailed cryogenic considerations required to ensure the proper functioning of this new window were simulated and verified experimentally. The data from numerous subsequent shots showed marked improvement in performance, which made this feature an essential component for all cryogenic NIF targets.
