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.

This technical note describes advances in the activity measurement of tritiated water with the method of scintillation counting in a solid fibre. The device described can be installed inline thus enabling the monitoring of a process without the need for taking samples. Due to the low overall costs, the system can be installed at various positions in a larger plant adding additional safety and better control over the process. The current technical note on the TRAMPEL setup (TRitium Activity Monitoring with a PhotomultipliEr in Liquids) focuses on the updates and enhanced detection limits due to an updated readout and DAQ system. It is now possible to measure inline down to activity concentrations of 104 Bq/ml, which is roughly one order of magnitude lower than previously reported. A possible memory effect as well as the influence of the filling level was investigated. All measurements were performed with a standalone (non-inline) cell but can be applied for a flow-through application, too.
