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.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

Whether they are based on fusion (JET, ITER, DEMO) or fission (e.g., CANDU type) or are cooled using molted salts [molten salt reactors (MSRs)], nuclear reactors generate significant amounts of waste in the form of low-level tritiated light water or heavy water, which generates risks for the environment and radiological risks for operating personnel. Given the wide range of tritium concentrations of tritiated water waste, processing it efficiently is possible only if the process is based on the combined process of liquid phase catalitic exchange and electrolysis of water. During this process, tritium is concentrated as tritiated water, which reduces the amount of waste and concentrates the water at the isotopic level high enough for further processing in view of tritium recovery, employing isotopic transfer in gas form. This paper reports on the modification of an industrial hydrogen generator in view of tritium compatibility to be used for further processing of tritiated (heavy) water for tritium recovery. Additionally, analysis will be made, and results will be presented on what will be the tritium/deuterium concentration profile in the generator and what influence the water holdup will have on the isotope concentration.
