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 continuous efforts dedicated to increase the predictive power of risk assessment for the large tritium releases imply models based on process level analysis. Tritium transfer from atmosphere to plants and the subsequent conversion into organically bound tritium strongly depend on the plant characteristics, seasons, and meteorological conditions, which have a large variability. This paper presents an inter-comparison of different models for canopy resistance and photosynthesis based on knowledge from plant physiology, agro meteorology, crop science, and atmospheric physics. The authors use Jacobs-Calvet-Ronda approach to model the canopy resistance combined with photosynthesis model and the data base taken from WOFOST crop growth model. The same photosynthesis model is used to assess the organically bound tritium production during the daytime and night time.
