Application of plasma-pyrolytic processing of solid radioactive waste on a floating nuclear power plant

Abstract

During the operation of a floating nuclear thermal power plant (FNPP), in particular the Akademik Lomonosov FNPP, radioactive hazardous waste (RW) is generated. There is no unified infrastructure for RW utilization in the far North of Russia. In this regard, to reduce chemical risks and the cost of ownership of raw materials, it is necessary to create processing complexes at the site of hazardous waste generation. The purpose of this work is to assess the economic efficiency of radioactive waste disposal, environmental safety and operational qualities of the RW plasma-pyrolytic processing unit at the FNPP. As a result of analytical studies, it was found that the economic efficiency of disposal of products processed by the new plant is more than 13 million rubles for 1 cycle of operation of the plant. It is determined that harmful factors affecting a person when working with the plant should be taken into account when designing the location of the plant at a nuclear power plant and means for automating the processing process. The amount of polychlorinated dibenzo-p-dioxins and dibenzofurans in the emissions of the processing plant does not exceed 0.014-0.02 ng/m3 in toxic equivalent (TE), and the elimination of possible accidents at the plant is relatively easy to localize and eliminate.
