Abstract
Introduction. At all stages of the life cycle of nuclear power plants (“Deployment”, “Design”, “Construction”, “Operation” and “Decommissioning”), there are a large number of different risks affecting the safety, schedule and cost of their realization. For nuclear power plant (NPP) projects at the life cycle stages there are many uncertainties that are transformed into project risks such as technological, financial, and radioactive waste cycle risks and others. Risk management is necessary for successful implementation of nuclear power plant projects.
Materials and methods. The article analyses risks in the NPP life cycle by several methods: risk assessment matrix and Pareto method. Identification and assessment of risks are carried out by the method of expert evaluation and with the use of scientific literature.
Results. Based on the results of the analysis, advantages and disadvantages of multi-criteria analysis methods with respect to NPP facilities are identified and described. For more in-depth risk analysis on the basis of the data obtained as a result of expert evaluation, the method of risk weighting distribution by factors is proposed, and graphical representations of analyzing the influence of identified risks by stages of NPP life cycle are presented.
Conclusions. The main objective of risk management is to reduce baselines such as cost, time and durability while unconditionally ensuring safety at all stages of the life cycle.
