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.

A general view is given of the significance and practical application of critical experiments for design and development of high-temperature gas-cooled reactor (HTGR) pebble-bed cores, mainly in the Federal Republic of Germany. Some experimental results are presented, and the theoretical methods that are used to evaluate different effects are discussed. The main target seems to be attained; for HTGR pebble-bed cores, reliable methods for nuclear design are available.
