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.

Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

Cross sections were measured for the 44Ca(n,)41Ar, 45Sc(n,)42K, and 51V(n,)48Sc reactions at neutron energies from 13.6 to 14.9 MeV. The neutrons were produced via the 3H(d,n)4He reaction on a neutron generator using a solid TiT target. The activation technique was used, and induced gamma activities were measured by a high-resolution gamma-ray spectrometer. Corrections were made for the effects of gamma-ray attenuation, random coincidence (pulse pileup), coincidence summing, dead time, neutron flux fluctuations, and low-energy neutrons. Statistical model calculations taking into account precompound effects were performed for all the reactions investigated, and the experimental results were reproduced well except for the (n,) reaction on the 45Sc target. Also, comparisons with the recent experimental data showed good agreement.
