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.

While present experiments are evaluated on the basis of confinement time, it is the fusion power multiplication factor, Q, and the fusion power that will be the parameters measuring the performance of ignition experiments and fusion reactors. We have determined the relationship of Q to τE and the Lawson number, nτE, for ohmically heated plasmas from the Princeton large tokamak (PLT). The values Q, τE, and nτE all increase with density at low densities. Above e ≃ 4 × 1013 cm−3, τEe ≃ 30 ms, or eτEe ≃ 1.2 × 1012 cm−3s, Q saturates; Q scaling has also been obtained on PLT as a function of toroidal magnetic field, plasma current, and auxiliary heating power.
