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.

The possibility of obtaining ignition in the Tokamak Fusion Test Reactor (TFTR) by means of very centrally peaked density profiles is examined. It is shown that local central alpha heating can be made to exceed local central energy losses (“central ignition”) under global conditions for which Q 1. Time-dependent one-dimensional transport simulations with a simplified transport model show that the normal global ignition requirements are substantially relaxed for plasmas with peaked density profiles. More realistic simulations with recently developed profile-consistent microinstability based models for electron and ion confinement show that TFTR may form a small centrally ignited region if peaked central density can be maintained.
