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 recommen...

Assurance of radiation and environmental safety of nuclear power plants (NPPs) implies development of an automated radiation monitoring system. In its turn, such a system presupposes that hydrological and meteorological monitoring should be arranged on the NPP site and in its vicinity. Monitoring is launched at pre-design stages of the NPP construction project, and continues during the construction, operation and decommissioning (dismantling) of the plant. The goal of the study is to generalize the results of hydr...

In connection with the significant destruction capability of tornado, the possibility of tornado passing through the areas comprising higher criticality rating facilities, such as nuclear power plants (NPP), is considered during the design and engineering (D&E) phase for such facilities. Corresponding probabilistic safety criterion in introduced into the decision-making basis concerning the consideration of tornado's impact onto the hazardous production facilities and destruction loads computation during the D&E p...

Atmospheric dispersion climatic conditions relate to main factors determining the environment ecological condition and radiation safety in the NPP area. This article is devoted to generalization of the author's studies concerning the atmospheric dispersion in the atmospheric boundary layer (ABL) for selection of the NPP sites and arrangement of ABL monitoring during the course of NPP construction and operation. Results of the ABL parameters climatic regime studies at Nizhny Novgorod NPP and Belorussian NPP are pro...
