Structure and content of the NPP life cycle stage management platform

Abstract

Introduction. Life cycle management of nuclear power plants is a complex process for many reasons, one of which is a large amount of information that requires understanding and analysis at all stages of the life cycle (LC): from the stage of “Site placement and selection” to the final stage of “Decommissioning”. NPP lifecycle management is a multifactorial process that includes obtaining and analysing a large amount of diverse information and actions. To consider all the details of this complex LC management process, it is necessary to create a digital platform, and to facilitate the process of information processing and management of NPP LC, a mathematical description is needed.Materials and methods. The purpose of this paper is to substantiate the need to create a management platform for NPP LC from the stage of placement to the stage of decommissioning. The elements of the management platform should be used in the implementation of strategic planning when making long-term decisions aimed at ensuring safety, given that the decommissioning of the plant is the most high-risk stage of the NPP housing and communal services.Results. The paper discusses the basics of creating an NPP LC management platform, including a mathematical description and algorithms of the methodology for managing it, presents the structure and image of the platform and provides an example of risk management.Conclusions. The structure and content of the NPP LC management platform are proposed, which combines all stages of the NPP life cycle, consolidates and systematizes information about all events and elements in digital format, considering factors: safety, cost, durability, time, the platform allows for analysis and evaluation of NPP LC stages.
