ABSTRACT

Atmospheric boundary layer (ABL) dispersion conditions relate to key natural factors that characterize radiation and environmental safety of nuclear power plants (NPPs). Therefore, the said conditions are studied in sufficient detail even at pre-design stages of NPPs construction. Given the ongoing development of nuclear power industry, synthesis of methodological approaches to NPP siting options with due account of atmospheric dispersion conditions is of great interest. Formal pursuit of requirements and recommendations contained in regulatory and technical documents can lead to unreasonably large scope of engineering surveys. The present article is aimed at developing a conceptual framework for studies of ABL atmospheric dispersion within the scope of engineering surveys. Main phases of aerological analysis of NPP siting options are described. Examples of atmospheric dispersion parameters calculation are provided. The aforementioned conceptual framework ensures optimal scheduling of atmospheric dispersion investigations. It is noted that the said conceptual framework is also applicable to aerological analysis of siting options for other potentially hazardous production facilities, such as chemical and metal manufacturing enterprises, thermal power plants and other projects.

Keywords: atmospheric dispersion, nuclear power plant, construction, environmental safety
