Both routine and inadvertent releases of hazardous materials or contaminants may occur at industrial sites. For example small releases of radioactivity are made when a buildup occurs in the working area of a nuclear reactor complex. The nuclear reactor plant itself is usually enclosed within a protective shell which is intended to prevent the accidental release of radioactive pollutants into the atmosphere. However should a crack or leak develop in the shell large amounts of radioactivity could be released. This study deals with the fate of contaminants released into the atmosphere under a variety of release situations. 1:200 scale models of the EOCR reactor building and surrounding silo and tank buildings at the Idaho National Engineering Laboratory, Idaho Falls, Idaho were put into the Meteorological Wind Tunnel at Colorado State University. Flow visualization used titanium-tetrachloride as a visible tracer gas. Concentration measurements were accomplished using ethane and propane as tracer gases, and gas chromatography techniques. The test program consisted of systematic releases from the base on the northwest face, center rooftop and the stack. In each case the release rate was maintained at low rates such that no appreciable jetting or plume rise was present. The program was repeated for cases of moderately unstable, neutral, moderately stable, and stable conditions in the wind tunnel. (Portions of this document are not fully legible)
