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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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 poloidal rotation of C V ions has been deduced, in the TJ-II stellarator, from spectral line shifts measured using a high-spectral-resolution spectrometer and a nine-fiber-channel system. Analysis of the data obtained has shown that a change of sign of the poloidal rotation direction occurs that depends abruptly on plasma density but is independent of the heating method. Whereas in low-density plasmas the poloidal direction corresponds to a positive radial electric field, at higher densities negative radial electric fields are deduced from the measured poloidal rotation. These measurements are in qualitative agreement with neoclassical theory calculations that predict a change in the sign of the radial electric field mainly because of a change in the ratio of the electron-to-ion temperature.
