Radiation factors in the areas of mineral deposit extraction are often rather intense, and they require a detailed study. One of such areas is the Taimyr Dolgan-Nenets District of the Krasnoyarsk Region, Russia, the administrative center of which is located in the town of Dudinka where at present the water supply system is being upgraded. This study is focused on investigation of the radiation factors on the territory under upgrade. In the framework of engineering and environmental surveys the gamma background and...

At present, the water supply system in the town of Dudinka (Krasnoyarsk Region, Russia) is being upgraded. In its turn, design of industrial projects stipulates development of an environmental protection action list. This study is aimed at forecasting environmental changes in the course of construction and operation of the water supply system. Results of the previous engineering and environmental surveys were used as input data for the forecast. Technogenic impacts of the project on the atmosphere, surface and gro...

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...

Infrastructure development of mineral fields, mining and processing of raw minerals usually cause substantial degradation of the environment. Therefore, projected construction of mining enterprises (MEs) envisages a detailed study of geoecological state of the mineral field territories at all stages of ME?s life time. Intensive growth of the mining industry, significant technogenic loads on the environment and the need for addressing industry-specific environmental protection issues stipulate the relevance of such...

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...

Since thermal energy is one of the most environmentally hazardous industries, the issues of environmental compatibility of thermal power stations (TPPs) construction are the priority. One of the main supporting pre-project documents on projected construction of TPP is a report on its environmental impact assessment (EIA). Due to the diversity of technology options for generating electrical power, as well as differences in natural and man-made, economic, social and other conditions of the territories intended for T...

A specific feature of thermal power plants (TPP) is the multivariate nature of their intense technogenic impact on the environment, including pollution of air, environmental waters, soils, as well as disturbance of the geologic environment. Besides, TPPs cause thermal, radiation, noise and electromagnetic pollution; they also induce physical littering of the terrain and problems associated with storage of ash waste. Due to the reasons stated above, a comprehensive study of environmental damage zones caused by TPP ...

Construction development of forest-tundra areas shall take into account their peculiar characteristics: enhanced susceptibility of landscape components to man-made impact, presence of permafrost, and also insufficient exploration of environmental conditions. These factors make it essential to carry out a detailed investigation of natural and man-made conditions as a part of engineering and environmental surveys during environmental feasibility study of the projected construction in such areas. This work is dedicat...

The main parameter for calculation of waterway openings of bridges and pipes, as well as cross sections of water-draining meliorative ditches, is maximum water flow rate. So, the reliable calculation of this parameter is essential for selection of appropriate design solutions. Snow melt flood volume is mainly determined by the volume of water stored in the snow cover when melting begins, and flow rate пїЅ by the rash of spring snow melt flood. In its turn, snow stock is considerably depends on the degree of covera...

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...
