Recommended Methods for Estimating Atmospheric Concentrations of Hazardous Vapors After Accidental Release Near Nuclear Reactor Sites

摘要

A literature survey was done which addresses the problems of atmospheric transport and diffusion of positively and negatively buoyant hazardous gases. Typical hazardous vapors of concern are chlorine, ammonia, and vapors from liquified natural gas. The objective was to determine the state of the art for analyzing hazards to nuclear power plants. Within this report, existing models with predictive capability have been categorized, and available measurements of transport, diffusion, and gas concentration have been organized by flow condition type in order to assess model accuracy. Operational models have not been found which are entirely suitable for NRC Regulatory predictive purposes. However, suggestions are made for model selection. Recommendations are also given for further research in areas where such efforts should prove profitable.
