HYDROLOGICAL AND METEOROLOGICAL MONITORING IN THE NIZHNY NOVGOROD NPP SITING REGION

Fedor Bryukhan

Abstract

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 hydrometeorological monitoring in the Nizhny Novgorod NPP siting region that began in 2011. A description is provided of the observation points set up by the Scientific & Industrial Association Gidrotekhproekt and the monitoring program which was harmonized with monitoring programs adopted for the national monitoring network points. Examples are given of computation of hydrological and meteorological characteristics. It is noted that monitoring is important not only for the automated radiation monitoring system but also it is essential for clarification of hydrological and climatic characteristics of the NPP site. At that, accumulation of observation data throughout a lengthy period is of great importance since it allows for detection of potential climatic changes in the area under study.
