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.

Supreme Court rules against Texas in interim storage case
The Supreme Court voted 6–3 against Texas and a group of landowners today in a case involving the Nuclear Regulatory Commission’s licensing of a consolidated interim storage facility for spent nuclear fuel, reversing a decision by the 5th Circuit Court of Appeals to grant the state and landowners Fasken Land and Minerals (Fasken) standing to challenge the license.

A bubble dynamics and mass transfer model GASBUB is presented that describes the pressure buildup in irradiated fuel above the melting point during energetic transients. The model describes the evaporation of fuel into pure vapor bubbles and into fission gasfilled bubbles. It is tested against the effective equation of state (EEOS) experiments jointly carried out by Sandia National Laboratories and Kernforschungszentrum Karlsruhe. In these experiments, fuel samples are heated up to ∼8000K. The model provides a basis for constructing an EEOS for irradiated fuel.
