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.

NRC updating GEIS rule for new nuclear technology
The Nuclear Regulatory Agency is issuing a proposed generic environmental impact statement (GEIS) for use in reviewing applications for new nuclear reactors.
In an April 17 memo, NRC secretary Carrie Safford wrote that the commission approved NRC staff’s recommendation to publish in the Federal Register a proposed rule amending 10 CFR Part 51, “Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions.”

A survey of large scale DT tokamak design studies shows that the confinement time required to achieve self-sustaining operation can be much less than that predicted by the recently reported neo-Alcator scaling. The excess containment is, in most cases, more than an order of magnitude larger than that required for a steady-state burning plasma. If neo-Alcator sealing remained valid to reactor conditions, means must be found to reduce confinement times to levels consistent with steady-state operation. The problem of excess confinement has not been addressed adequately in the available literature. A positive aspect is that this excess confinement is likely to be available without engineering or physics penalty. A constructive use to which this excess confinement can be put is to burn advanced fusion fuels instead of the DT reaction, and thereby reap the practical benefits of reduced energetic neutron fluxes.
