Abstract
Background. The article considers the way to solve the urgent problem of expertise and quality testing of specific products of original production facilities for the utilization of dismantled structural elements of nuclear power plants during their decommissioning. Materials and methods. The methodology for calculating the probabilities of errors in the process of checking the quality of finished products of mass production in the field of utilization and processing of structural materials of power units with nuclear reactors, in order to reuse these products, materials and products for a new purpose, is presented. A method of examining the quality of such products is proposed, and the result is estimated – reducing the likelihood of defective products being missed when inspecting several parameters that determine the physic technological value of a closed cycle of handling structural materials of nuclear power plants. The method opens up the possibility to optimally select and evaluate the effectiveness of various combinations of tools for non-destructive examination the finished products quality of in general, according to the criteria of rational use of natural resources and environmental acceptability, economic feasibility; Based on the results of the evaluation of the quality of finished products, determine the technological map of output examination for the processing of dismantled structural components of nuclear power plants at the stage of eliminating their negative nuclear legacy. Results and conclusions. The presentation and substantiation of the main scientific provisions and principles on the basis of which a system analysis of product quality is based in a closed-loop format for handling structural materials of nuclear power plants.
