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 spent electrolyte arising from pyroprocessing should be recycled to reduce the volume of high-level radioactive waste. To establish the spent electrolyte process by a phosphate conversion method, a preliminary experiment that followed a thermodynamical approach and used an electric furnace under argon gas atmosphere was carried out. The results obtained are that most thermodynamic properties of target phosphates acquired by the CALPHAD method were good in agreement with the experimental result; lithium and rare earth elements (REEs) tend to form the precipitate as orthophosphates, but other alkali metal (AL) and alkaline earth metal elements do not form the orthophosphate particles; and some elements such as ALs could form insoluble double salts with REEs.The development of separation techniques of insoluble and soluble fission product elements will be the next challenge.
