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.

Direct waste transfer process quickens at Savannah River Site
The Department of Energy Office of Environmental Management’s liquid waste contractor at the Savannah River Site this month marked the first direct transfer of decontaminated waste from the Salt Waste Processing Facility (SWPF) to the Saltstone Production Facility (SPF). This is a new step in optimizing waste processing, according to the DOE.

Oil-free reciprocating pump has been developed for tritium services at Tritium Process Laboratory (TPL) in Japan Atomic Energy Agency, and used for more than 20 years without any big trouble. One disadvantage of the above reciprocating pump is rather high ultimate pressure and drastically decreasing of the pumping performance at the lower suction pressure. The main reason would be that the check valves could not open enough at lower suction pressure, which are installed in the piston of the pump. In order to improve this disadvantage, solenoid valves option was tested instead of the check valves. Intentional opening & closing of the solenoid valves, linked with reciprocating motion cycle of the pump, improved more than one order of the ultimate pressure drastically. High evacuation performance was also demonstrated by the combination of molecular DRUG pump and the improved reciprocating pump with solenoid valve.
