Abstract
Diagrams and algorithms for choosing the optimal variant of the technological process for decommissioning of nuclear facilities, as well as for determining the degree of stability of the chosen variant in conditions of uncertainty of the initial data, have been presented. Uncertainties of expert assessments and calculated values of some of these data give rise to uncertainties in the values of indicators for options for the technological process of decommissioning nuclear facilities. A scheme for selecting the optimal variant of the technological process and determining its stability in conditions of uncertainty of the indicators characterizing each considered variant of decommissioning (the list of possible indicators is presented below) is considered. The optimal variant of the technological process is chosen on the basis of a complex indicator that combines particular indicators in the form of a linear superposition for each considered variant of the technological decommissioning process. According to the proposed scheme, the optimal variant of the technological process is chosen according to the maximum for all considered decommissioning options, the average expected value of the complex indicators for these options, and the stability of the optimal variant of the technological process is tested against the complex indicator for the optimal variant of the technological process for the minimum possible value for each particular indicator.
