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.”

This paper presents experiments carried out to study the influences of transverse vibration on horizontal gas-liquid two-phase flow. The experiments considered the transverse vibration over a wide range of vibration frequencies and vibration amplitudes. Five typical flow regimes were observed. The fluid flow conditions in steady state and transverse vibration were compared. The traditional flow regime transition lines did not match the gas-liquid flow in channel under transverse vibration. The results suggest that vibration frequency mainly affected the flow regime by promoting the aggregation of gas slug, while vibration amplitude mainly influenced the fluctuation height of the gas and liquid interface.
