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.

ARPA-E announces $40 million to develop transmutation technologies for UNF
The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $40 million in funding to develop cutting-edge technologies to enable the transmutation of used nuclear fuel into less-radioactive substances. According to ARPA-E, the new initiative addresses one of the agency’s core goals as outlined by Congress: to provide transformative solutions to improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel.

Multi-component adsorption isotherm is determined experimentally when He, H2 (or D2) and CH4 are adsorbed on activated carbon (AC) plated on a cryopanel cooled at cryogenic temperature and desorbed at room one. It is correlated to the Langmuir-Freundlich-type one. The equilibrium isotherms for their respective single-component adsorption processes are correlated in terms of the Langmuir-Freundlich-type ones, and the isotherm when the three components of He, H2 and CH4 are adsorbed at the same time is correlated in terms of a naturally-extended multi-component one without any changes in the original constants included in the single-component one. Rates of the isotopic exchange reaction of D atom between CH4 and D2 on AC between 10 K and room temperature are also determined. After eliminating the effects of natural isotope of 13C included in CH3D, CH2D2, CHD3, CD4 on mass-spectrometric measurements, it was found that the isotopic exchange rate of CH4 + D2 = CH3D +HD and so on was found to be so late that any detectable effect was not observed.
