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.

NRC v. Texas: Supreme Court weighs challenge to NRC authority in spent fuel storage case
The State of Texas has not one but two ongoing federal court challenges to the Nuclear Regulatory Commission that could, if successful, turn decades of NRC regulations, precedent, and case law on its head.

The absolute cumulative fission yield of 140Ba and the relative yields of 131I, 132Te, and 141Ce were measured for 232Th irradiated in a 252Cf fission spectrum of neutrons. The irradiation was performed using two 232Th foils in contact with a nominal 1-mg 252Cf source in a large evacuated area for 41 days. The absolute yield of 140Ba was deduced from an absolute measurement of its daughter product 140La using a calibrated NaI(Tl) detector. The activities of 131I, 132Te, and 141 Ce were measured relative to the 1596-ke V gamma ray of 140La using a 43-cm3 Ge(Li) detector. The fission rate for the yield measurement and the integral fission cross section were measured using mica solid-state track recorders.
