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.

Work has been done to assess the ability of electron cyclotron emission (ECE) measurements to resolve rotating magnetohydrodynamic (MHD) islands in the high-temperature plasmas of ITER. In ITER discharges the high electron temperature will cause relativistic broadening of ECE frequencies, significantly larger than experienced in current magnetic fusion devices. The broadening will result in spatial averaging of measured Te oscillations and hence a reduction of resolution. This effect is quantified by using a code that calculates the EC absorption and emission for an ITER scenario, and by using simulated Te data the reduction in amplitude is determined. It is found that the reduction is modest and that it should be possible to measure MHD islands of 1 cm and larger.
