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 Inertial Fusion Reactor KOYO, proposed by ILE Osaka was completed in its first phase study in 1992, and recent updates including new features have been released up to now. It is based on potentially key achievements in Inertial Fusion Energy (IFE) physics: development to achieve required laser efficiency, implosion stability and gain, pellet fabrication, chamber maintenance, engineering feasibilities, and cost of electricity.
Neutron (target) emission profiles are reported assuming direct drive compressed targets (500 g.cm-3), which have been described with different approaches in stationary transport models. A full three-dimensional description of the reactor has been used to perform the neutronic analysis. Neutron spectra and flucnecs are calculated, and compared with previous one-dimensional results showing the differences in using both approaches. Some figures indicating the neutron flux expected through deep penetrations impinging on the final optics are also presented, representing its coincidence at long distances with the uncollided flux.
The reported consequences are those related to the activation of the materials: shallow land burial (SLB) and recycling. Those radiological responses have been studied for the SiC tubes (components of the blanket), graphite (reflector), and ferritic steel HT-9 (structural wall).
