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.

PNNL seeks high-energy neutrons from SpaceX launch of Polaris Dawn
When a SpaceX rocket lifted off from Kennedy Space Center on September 10 (see video here), sending a crewed commercial mission into low Earth orbit, an experiment designed by Pacific Northwest National Laboratory was onboard. Several high-purity metal samples will orbit Earth and absorb cosmic radiation for five days—including that from the Van Allen radiation belt—to help the lab answer questions about the radiation environment for manned space missions, according to a news release from PNNL.

Session Organizer:
Fossil uranium is often separated into at least two categories, such as low-enriched uranium (LEU, with <20% U-235), and high-enriched uranium (HEU, with >20% U-235). Occasionally, LEU is further split into categories such as LEU+ (5-10% U-235) and high-assay LEU (10-20% U-235). However, plutonium never appears to be sub-divided into sub-categories, regardless of whether it is, for example, reactor-grade or weapons-grade plutonium. This panel will discuss the pros and cons of potentially dividing plutonium into sub-categories of importance (similar to uranium) and the potential to develop an ANS position statement support this position.
