Abstract: The article presents a model for comprehensive assessment and improvement of the comparative analysis method for nuclear reactor types in Ukraine, based on the methods proposed in the KIND and CENESO projects. The formation of key and auxiliary sets of indicators for analysis was carried out in accordance with the recommendations of IAEA regulatory documents and taking into account the national characteristics of Ukraine's energy system. The stages of a systematic approach to comparative analysis were formalized, and an evaluation algorithm based on attributes and their indicators was developed. The purpose of improving the method is the need to simultaneously take into account quantitative and qualitative attributes and their indicators, use adequate methods for determining their weights, and develop methods for the comprehensive evaluation of attributes and their indicators. The developed modifications of the analysis methods make it possible to determine the relative values of nuclear reactor types, taking into account expert assessments and the requirements of decision-makers. A weighted "generalized integral value function" was proposed for the comprehensive assessment of nuclear reactor types. The developed improved method is based on a systematic approach, the formation of an array of quantitative and qualitative attributes and their indicators for the corresponding groups of objectives, the method of hierarchy analysis, and the method of multi-criteria optimization. The detailing of the parameters of nuclear reactor types makes it possible to take into account the requirements of decision-makers regarding technical, economic, safety, and other attributes and their indicators.
Keywords: nuclear reactor types, INPRO method, key indicators, comparative analysis, systematic approach, expert assessment, weighting coefficients, generalized value function, comprehensive assessment of alternatives, optimal choice, decision-making.
