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.

In order to establish a molten salt blanket, the microscopic corrosion of JLF-1 steel (Fe-9Cr-2W) was investigated by comparing with its alloying elements (pure Fe, Cr, and W) and pure Ni. Impedance measurements in LiF-NaF-KF at 500°C and scanning electron microscope and transmission electron microscope observations were performed. The charge transfer resistance of JLF-1 steel was similar to that of pure Fe, three times higher than that of pure Cr, and ten times lower than that of pure W and Ni. The concentration of W in JLF-1 steel was higher near the surface than at the bulk, which also indicated the higher corrosion resistance of W than Fe and Cr. For corrosion resistance of JLF-1 steel, the degradation by 9 mass % Cr was more effective than the improvement by 2 mass % W. The dominant corrosion was the intergranular corrosion at lath boundaries, leading to lath dropout for JLF-1 steel, the intergranular corrosion along grain boundaries for pure Fe, pitting corrosion for pure Cr, and entire surface corrosion for pure W and Ni.
