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.

College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

Plasma-wall interaction in fusion devices is unavoidable and leads to material erosion, dust formation, and tritium retention. Erosion of plasma-facing material and generation of dust inside ITER can significantly affect the operation. This is because the total in-vessel dust and tritium inventories during an operational campaign are required to be below limits of 1000 and 1 kg, respectively, imposed by safety considerations. To ensure respect of these limits, dust and tritium inventories should be monitored during the operational campaign of ITER. The level of erosion will be monitored by laser ranging techniques. To manage the dust inventory, local dust monitors from a number of locations will measure local dust concentration and accumulation. An additional important issue is dust lying on hot surfaces. In terms of safety, "hot dust" inventory is also strictly limited. Several techniques have been proposed to monitor the hot dust amount. Finally, the in-vessel tritium inventory must be limited and monitored. Assessment of the deficit in the tritium fuel supply is a way of measuring in-vessel tritium retention; however, this will have to be complemented by local surface analysis. Several diagnostic methods are introduced and compared with each other in order to find the most promising ITER-relevant concepts.
