Роль геомониторинга и эффективность инженерно-технических мероприятий для обеспечения дальнейшей деятельности полигонов длительного приповерхностного хранения радиоактивных отходов

Abstract

The main thread to geoecological safety of the environment is the disposed radioactive waste from the first stage of atomic industry development when even the concept of storage (disposal) of such waste was absent. Substantiation of further safe exploitation of radioactive waste (RW) storage site, because of the absence of an alternative, was carried out on the basis of geomonitoring observation, however the data of these works is not widely covered. Therefore the author of this article tried to summarize the results of decennial research of the development, introduction and improvement of geomonitoring methods at one of RW storage sites taking into account physical-geographical and geological conditions of its disposition. For geomonitoring conduction a net of boreholes was drilled with core sampling including sampling through RW mass as well as below storage facility foundation. Core material and boreholes themselves have become the objects of a lot of scientific researches: geological, hydrogeological, hydrochemical, geophysical, geothermal, radiochemical, physical-chemical and microbiological. Taking into account the migration of radionuclides in the site, engineering and technical arrangements were developed and introduced. Their implementation allows to prolong the validity period of the site.
