The approaches to the evaluation of equipment's operability and safety of NPP are discussed. The purpose of this article is the conceptual development of approaches, models and methods that make possible to obtain as-sessments of the equipment's operability and safety of NPP taking into account possible emergent properties of the systems. The scientific and practical value of the results of this article is to develop approaches, models and methods that allow us to obtain estimates of the equip-ment's operability and NPP safety, taking into account the possible emergent properties that are neglected in approaches, models and meth-ods well-known today. General approaches to the construction of mathematical models of the responsible equipment of NPP, which taking into account the interaction of various external factors that can lead to synergistic effects, are considered. The main result is the established possibility of mathematical modelling of NPP equipment in the form of systems of connected boundary and initial boundary value problems, which allows us to take into account possible emergent properties. The main conclusion is promising applications semi-discretization meth-ods for numerical analysis of NPP elements. The value of obtained results consists in developing of theoretical foundations for estimating the equipment's operability and safety of NPP by taking into account possible emergent properties.
