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 small fast reactor has the potential to be utilized as a power source applicable to diversified social needs and to reduce capital risks. At remote sites where the population is small and plants cannot be economically connected to a power grid, power sources without refueling whose capacities are <50 MW(electric) are required because the fuel transfer cost is expensive at such sites. In the present study, a small lead-bismuth-cooled core with a 30-yr lifetime has been developed, and a simple plant system without refueling has been sketched. The dimensions of the major components are determined to evaluate its economic potential. Transient analyses of anticipated-transient-without-scram events show that the design has passive safety features suitable for a remote power source.
