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.”

An electrolytic cell, essentially composed of a solid polymer electrolyte (SPE) film and porous dimensionally stable electrodes (DSEs), was designed to reduce the electrolytic voltage in an electrolyzer. The device achieved a tritium recovery factor of 0.836±0.021 for a volume reduction factor of five when operated at a current of 6 A, while maintaining a water bath temperature below 2 °C. Sample and standard waters were simultaneously enriched by connecting two electrolytic cells in series. The sample water was first enriched using a commercially available apparatus with a large electrolytic current of 50 A until the volume in the sample water was reduced to approximately one fifth of the original volume. This "two-stage electrolysis" enrichment was applied to coastal seawaters from the Aomori prefecture. Tritium concentrations, ranging from 0.2 to 0.5 Bq/L, were found, with a measurement error (i.e. a statistical error of one sigma) of ca. 10% of the obtained values.
