Atmosphere Dispersion in Nuclear Power Plants Siting, a Safety Guides

---

The atmosphere is an important pathway for the transport of radioactive releases from a nuclear power plant to the environment and thereby to man. It is necessary therefore to have adequate information about this pathway in order to estimate the dispersion of radioactive releases to the population in the region and thus be able to assess the radiological impact on man. The present Guide describes the meteorological phenomena and mechanisms involved in the dispersion of the released effluents in the atmosphere, discusses the methods which may be used to calculate the concentration and deposition in the region, specifies the data needed for input to these models, states the characteristics of the requisite instrumentation and data analysis systems and discusses certain related topics. Methods are presented for estimating concentration for short and long periods of emission over a wide range of types of radioactive releases. The evaluation of dose to individuals and population, given the concentration, is dealt with in national and international publications. It has been customary in the safety analysis of nuclear power plants to prepare dispersion estimates with different degrees of emphasis and various accuracy requirements at the stages of (a) site survey, (b) site evaluation, and (c) operation of the plant, and for accident contingency planning. Recommendations given in the present Guide generally apply to a distance of up to about 10 km depending upon the complexity of the terrain. The extension to longer distances may be made with caution and to the satisfaction of the regulatory authority
