Abstract
A new scheme has been presented to select the optimal option for decommissioning of a typical nuclear facility and to analyze its stability using the Monte Carlo method. According to the proposed scheme, the optimal option is chosen by multiple Monte Carlo realizations of the particular indicators for each considered option of decommissioning, ranking the options according to the complex indicator in descending order, and calculating the total number of places for each option. The option with the minimum total number of seats is the best. Similarly, the analysis of the stability of the selected decommissioning variant of the nuclear power plant is carried out, for which the entered stability indicator is calculated. The numerical experiments have shown the efficiency of the developed scheme for choosing the optimal variant of the decommissioning of a nuclear facility and its stability under conditions of uncertainty in the initial data. The optimal variant of decommissioning and its stability for a conditionally real object have been numerically calculated.
