Abstract

The main aspects limiting the widespread development of nuclear energy—the consequences of possible severe accidents and the problem of radioactive waste management—are considered. It is shown that modern computational tools and digital technologies can successfully solve the problems of substantiating and ensuring the safety of nuclear facilities, including modeling the states and processes occurring in a reactor installation, and the entire complex of nuclear power plant (NPP) systems, the spread of contaminants in emergency situations, the choice and justification of solutions on decommissioning nuclear and radiation hazardous facilities, and the disposal of radioactive waste (RW).

Additional information

On February 25, 2020, a meeting of the Presidium of the Russian Academy of Sciences was held, dedicated to the safety of nuclear energy. A report on this topic was made by Academician L.A. Bol’shov, Research Supervisor of the Nuclear Safety Institute of the Russian Academy of Sciences (IBRAE RAS), the only institute of the Russian Academy of Sciences specializing in integrated research into the problems of safety of nuclear facilities and industry. According to the members of the RAS Presidium, this was one of the most relevant meetings. Its participants stated that, contrary to some concerns that had arisen after the accidents at the Chernobyl and Japanese Fukushima-1 nuclear power plants in 1986 and 2011, the world had returned to the widespread use of nuclear energy. Russia, having overcome the negative attitude towards nuclear energy and the tendency to its stagnation and reduction, is again increasing the share of nuclear generation in the world energy basket and is implementing a large-scale development strategy for a two-component closed-cycle nuclear energy system, which was clearly demonstrated at the RAS Presidium meeting by the speaker and the representatives of the State Atomic Energy Corporation Rosatom who followed him.

The discussion of problems and long-term plans for the development of the country’s nuclear energy complex was joined by E.O. Adamov, Dr. Sci. (Eng.); RAS Academician G.N. Rykovanov; V.I. Il’gisonis, Dr. Sci. (Phys.–Math.); RAS Academician N.N. Ponomarev-Stepnoi; RAS Corresponding Members V.K. Ivanov and V.V. Ivanov; and RAS Academicians A.N. Lagar’kov, V.A. Tutel’yan, L.M. Zelenyi, E.L. Choinzonov, B.N. Chetverushkin, R.I. Nigmatulin, and V.E. Fortov.
