Technological considerations in emergency instrumentation preparedness. Phase II-C. Emergency radiological and meteorological instrumentation for fuel reprocessing facilities

A reference fuel reprocessing plant, postulated to process fuels from light water reactors with initial enrichments less than 5 percent 235U or equivalent fissile content, with exposures in the vicinity of 40,000 MWd/MTU and cooling times of approximately 150 days, was used to determine the sources and magnitudes of radionuclide releases to the environment in the event of postulated accidents within the plant. Based on these estimates of accident generated conditions, performance criteria were developed for instrumentation systems to (1) immediately detect the occurrence of a release, (2) determine the magnitude and direction taken by the release, and (3) permit estimation of the impact of the release on the environs of the plant
