NPP as a technically complex facility. Global reliability management using “Between True and False” method

Abstract

The presented research article gives an overview of modern aspects of the concept of reliability and risk management of technically complex construction objects using the example of a nuclear power plant (NPP). Through the analysis of domestic and foreign approaches to the study of NPP reliability management systems, the paper defines the vector of development of applied science in the field of project reliability assessment. The author outlines the problems of development of an integrated system of organizational and economic reliability management of the main stages of construction of nuclear power facilities. The article presents the main theses and description of the author’s development of the methodology of reliability assessment of the technically complex NPP system on the basis of multi-criteria approach. It is proposed to use stochastic and deterministic methods of reliability assessment for the technically complex NPP system. The relevance of applying the theory of fuzzy sets is substantiated in the context of the analyzed problem when assessing the degree of reliability of the nuclear power plant as a technically complex real estate property. The method of network graphs construction, forming the basis of the applied software of the organizations performing the functions of customer and contractor of NPP construction, is considered as a sub-base of the system of project reliability assessment by its stages and phases. The article formulates the problems of reliability and risk management, draws conclusions and recommendations on the prospects of NPP reliability management systems development, and identifies directions of further research in this field. It is proposed to create a global map-scheme of the international market of nuclear industry facilities based on their reliability data. The paper substantiates the fact that the creation of such a map will make it possible to inform humankind publicly about the state of energy facilities using peaceful nuclear technology.
