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.”

The ratio of capture to fission cross section, α, has been measured for 235U and 239Pu in the neutron energy range from 8 to 60 keV. A pulsed neutron beam from a 7Li Van de Graaff source was used. The absorption was found by a comparison of the scattered neutrons from the fissile sample with those from a non-absorbing lead sample. The fast fission neutrons were simultaneously detected with an organic liquid scintillator. The normalization of the α (239Pu) data was slightly changed with respect to the values reported earlier in the light of recent evaluations.
