THE MEMBRANE METHOD OF ASSESSMENT OF ORGANIZATIONAL AND TECHNICAL RELIABILITY AND AGGREGATE RISK OF NPP CONSTRUCTION PROJECTS

This study aims to enhance the organizational and technical reliability of design solutions in nuclear power plant (NPP) construction projects, particularly under risk conditions. It focuses on identifying effective strategies to manage and mitigate risks throughout the project life cycle, ensuring the successful and safe completion of technically complex NPP facilities. The conducted system analysis is the basis of methodical recommendations on the selection of a rational option for the organization of the construction of a nuclear power plant (NPP). The results of the research article are based on the analysis of practical activities of the participants of the construction project of a unique and technically complex NPP facility, aimed at improving the organizational and technical reliability of design solutions at all stages of the project life cycle under risk conditions. Conclusions and practical recommendations have been made on the basis of the author's membrane -method simulation model of risk analysis, developed using a modern approach to the application of automated systems of production process planning for the implementation of the NPP project.
