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 first Chinese in-situ tritium release experiment is being carried out in the fission reactor SPRR-300 in the Southwest Institute of Nuclear Physics and Chemistry (SWINPC). Several runs of the experiment were conducted to study tritium generation and release behaviors from China-made γ-LiAlO2 pellets. The effects of some key operational factors (temperature, sweep gas composition and flow rate) upon tritium release were studied. The results show that the equilibrium tritium release rate at different temperatures approached the tritium generation rate obtained from neutron calculations. The tritium concentration in the sweep gas decreased with increasing the flow rate. Addition of a small quantity of hydrogen greatly enhanced the release of tritium. It was also found that the tritium released in the sweep gas was mostly in the form of HT. However, when the generated tritium was not purged in time, the HTO fraction increased gradually. By using the inventory difference method, through the special run which lasted 72 hours, we determined the diffusion coefficient for tritium in γ-LiAlO2. The obtained diffusivity and its activation energy were compared with those from other experiments. It was found that the value of Q was close to those from LILA and TTTEx experiments, but the value of D0 was smaller.
