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.

Industry Update—June 2025
Here is a recap of industry happenings from the recent past:
DOD selects companies for its installations microreactor program
The Department of Defense has selected eight technology companies as being eligible to seek funding for developing microreactor technologies as part of the DOD’s Advanced Nuclear Power for Installations program. That program seeks to “design, license, build, and operate one or more microreactor nuclear power plants on military installations . . . to support global operations across land, air, sea, space, and cyberspace.” The selected companies are Antares Nuclear, BWXT Advanced Technologies, General Atomics Electromagnetic Systems, Kairos Power, Oklo, Radiant Industries, Westinghouse Government Services, and X-energy. Specific objectives of the DOD program are to “field a decentralized scalable microreactor system capable of producing enough electrical power to meet 100 percent of all critical loads” and to “utilize the civil regulatory pathways of the Nuclear Regulatory Commission to stimulate commercial nuclear microreactor technology development and the associated supply chains in the U.S.”

The aim of this work is to obtain a multicomponent, numerically simplified and stable distillation model, with simultaneous correction of the temperature and flow-rate (liquid and vapour phases) profiles along the column. The proposed model should be considered as an introduction to the multicomponent distillation calculation via computer and not an alternative to the existing rigorous methods. In the model the compositions are evaluated by solving a system of linear equations, while the flow rates are calculated “explicity” by means of enthalpy balances. A few iterations are required to obtain the solution and the temperature profile.
