The subject of research is the approaches, methods and models that allow adequately and correctly evaluate the impact regimes and conditions of nuclear and heat power plant units on structural materials, reliability and efficiency of the elements of their critical systems and equipment that could be used effectively in optimization modes (loads) reactors of NPP and TPP to increase the terms of their high-performance exploitation, technogenic and ecological safety. The purpose of the first stage of fundamental research work is the analysis of modern and development, assessment of reliability and determination of the possibilities of using new approaches, methods and models for the justification of the working capacity of equipment elements of nuclear and heat power plants. The methods of scientific research: methods of probability theory; methods of mathematical modeling; methods of simulation; experimental research methods. These methods, within the framework of a unified approach to conducting scientific research, allow us to describe, on the basis of the theory of mathematical modeling, the change in the working capacity of elements of the equipment of nuclear and heat power plants of the NPP and TPP during operation on the basis of the use of methods of continuum mechanics, the theory of thermal conductivity and thermo elasticity, the theory of creep, the theory of thin plates and shells, theory and methods of simulation, probability theory, theory and optimization methods. The scientific novelty of such an approach is that it will enable to take into account the complex influence on the efficiency of the equipment's elements of nuclear and heat power plants of the NPP and TPP, the modes and conditions of their operation, the parameters of technological processes, radiation irradiations and mechanical stresses that cause deformation, creep, corrosion, degradation of the properties of these elements. Practical value consists of the fact that the results of the performed research in the form developed by the new and improved existing theoretical bases of substantiation and efficiency elements of the equipment of nuclear and thermal power plants will the solution of the problem of the continuation of the terms of the effective and safe operation of reactors of NPP and TPP by the optimal choice of modes of operation according to the characteristics of the strength of the structural elements of technical condition and working capacity of systems and equipment Product Description popup.authors Єсипенко Тетяна Олексіївна Єфімов Олександр В'ячеславович Анциферова Алеся Олександрівна Вільк Ольга Олексіївна Гаркуша Тетяна Анатоліївна Гриценко Олена Володимирівна Дягілев Вадим Олександрович Каверцев Валерій Леонідович Камчатна-Степанова Катерина Валеріївна Ліфшиць Петро Володимирович Литвиненко Олександр Григорович Орлова Тетяна Олександрівна Пилипенко Микола Миколайович Потаніна Тетяна Володимірівна Ромашов Юрій Володимирович Федорищева Тетяна Петрівна popup.nrat_date 2020-04-02 Close
