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.

Webinar: MC&A and safety in advanced reactors in focus
Towell
Russell
Prasad
The American Nuclear Society’s Nuclear Nonproliferation Policy Division recently hosted a webinar on updating material control and accounting (MC&A) and security regulations for the evolving field of advanced reactors.
Moderator Shikha Prasad (CEO, Srijan LLC) was joined by two presenters, John Russell and Lester Towell, who looked at how regulations that were historically developed for traditional light water reactors will apply to the next generation of nuclear technology and what changes need to be made.

Tritium Process Laboratory (TPL) in Japan is operated by the Japan Atomic Energy Agency (JAEA) and was established as the only facility to handle over one gram of tritium in Japan in 1985. Since March 1988, the TPL has been operated safely with tritium, and no tritium release accidents have been occurred. The maximum tritium concentration of a three-month average in a stream from a stack of TPL to environment was 350 Bq/m3, and is about 14 times smaller than that of the legal release limit in Japan. The failure data have been analyzed for several main components of the safety systems such as pumps and monitors. The tritium waste data has also been accumulated as liquid and solid waste from TPL. Through this operating experience, a significant database for the safety systems of the TPL has been accumulated. This data can provide a source of reliability information for a future fusion facilities.
