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.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

An unmitigated quench of a toroidal field (TF) magnet has been proposed as an extremely unlikely event for International Thermonuclear Experimental Reactor (ITER) Engineering Design Activity safety analysis. While the frequency of such an event is highly improbable (<1 × 10-6/yr), the public safety consequences of this event must be explored because the TF magnets are located midway between the two primary confinement barriers of the ITER design. These confinement barriers are the vacuum vessel (VV) and the cryostat. An unmitigated quench has the potential for producing melting of the magnet. If molten material from the magnet were to impinge on the walls of the VV and cryostat, these walls could fail, resulting in a pathway for release of radioactive material to the environment from the VV. A model has been developed at the Idaho National Engineering and Environmental Laboratory called MAGARC to investigate the consequences of this accident. This model is described in detail, and results from this model used in ITER safety analysis are presented.
