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 generic reactor model is used to examine the economic viability of electricity generation by magnetic fusion. The simple model uses components that are representative of those used in previous reactor studies of deuterium-tritium burning tokamaks, stellarators, bumpy tori, reversed-field pinches, and tandem mirrors. Conservative costing assumptions are made. The generic reactor is not a tokamak but rather it is intended to emphasize what is common to all magnetic fusion reactors. The reactor uses a superconducting toroidal coil set to produce the dominant magnetic field. To this extent, it is not as good an approximation to systems, such as the rev er sed-field pinch, in which the main field is produced by a plasma current. The main output of the study is the cost of electricity as a function of the weight and size of the fusion core — blanket, shield, structure, and coils. The model shows that a 1200-MW(electric) power plant with a fusion core weight of ∼10000 tonnes should be competitive in the future with fission and fossil plants. Sensitivity studies that vary the assumptions show that this result is not sensitively dependent on any given assumption. Of particular importance is the result that this scale of fusion reactor may be realized with only moderate advances in physics and technology capabilities.
