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.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

Electricity markets are changing because of (1) the addition of wind and solar generating capacity and (2) the goal of a low-carbon electricity grid. The large-scale addition of wind and solar photovoltaics results in low wholesale electricity prices at times of high wind and solar output and high prices at times of low wind and solar input. Today, gas turbine combined cycle (GTCC) plants burning natural gas or oil provide dispatchable electricity and provide the most economic method to match electricity production with demand. Nuclear Air-Brayton Combined Cycles (NACCs) with heat storage and a thermodynamic topping cycle enable base-load nuclear plants with sodium or salt coolants to provide dispatchable electricity to the grid and heat to industry. This capability maximizes nuclear plant revenue and enables a base-load nuclear reactor with NACCs to be a low-carbon replacement for a GTCC. The NACC power cycle, alternative heat storage technologies, and development status of the different technologies are described. The technology applies to other heat generating technologies including high-temperature concentrated solar power and future fusion systems.
