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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

The potentiality of a new type of flowmeter, intended to measure the coolant flow rate through a fuel assembly of a nuclear reactor, was investigated. This new type of flowmeter, the nuclear turbine flowmeter, has the advantage that no extra signal wires are needed; the signal can be read by a neutron detector positioned in its vicinity. The influence of a rotating test turbine (installed in a setup at the Hoger Onderwijs Reactor in Delft, The Netherlands) on the signals of several neutron detectors was analyzed. From the results, it appeared that the rotation frequency of the test turbine could easily be detected by all neutron detectors used. The influence of the rotating test turbine on the signals of detectors positioned nearby is strong compared with the background noise level found for in-core neutron detectors in boiling water reactors.
