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 global drift-fluid model is employed to study plasma discharges in linear devices including self-consistent treatment of electric fields. Numerical results on plasma rotation and turbulent scales are found to be very similar to experimental observations. Also a pronounced intermittent plasma transport in radial direction is observed for particular conditions. Extended filaments are expelled from the plasma column. In the simulations numerical probes have been implemented for detailed statistical analysis of the plasma fluctuations suitable for comparison with experimental data. In this contribution particular attention is paid to the impact of the plasma source on the intermittencies in the plasma column. It is found that even slight modifications in the shape of the plasma source can strongly change the plasma dynamics.
