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.

Uranium prices see increase as October begins
Uranium prices reached $81.9 per pound on October 1, the highest level in more than a month, according to online information source Trading Economics. The company reported that the last time prices were this high was on August 23, when they passed $82 per pound. Since the beginning of 2024, uranium prices have seen a decrease in price of about $9.10 per pound, or about 10 percent. Those statistics are based on trading on a contract for difference (CFD) that tracks the benchmark market.

We performed a systematic benchmark study of several Monte Carlo codes for neutron deep penetration experiments at 0 deg, which were previously performed using 40-, 65-, and 137-MeV quasi-monoenergetic neutrons and using continuous-energy neutrons up to 400 MeV. Neutron energy spectra behind shields and the attenuation lengths of the neutron flux are compared between the experiments and the calculations. All calculations generally well reproduce the energy spectra and the attenuation lengths measured in the experiments. The attenuation length obtained as a function of the incident neutron energy in this study rapidly increases with the incident energy.
