The paper is concerned with an alternative to the existing concept of expanding the nuclear energy fuel resources in terms of fissile isotopes by producing 233U from 232Th in fusion reactor blankets. The new concept offers several advantages, including a substantial decrease in the risks of environmental pollution due to the low radioactivity of the recycled fuel. The study focuses on several scenarios for the development and use of a new fissile isotope in thermal neutron spectrum reactors (pressurized water reactors) and demonstrates the possibility of closing the fuel cycle in a system of thermal reactors with a fusion neutron source using heavy nuclei.

“…The options for promoting the hybrid concept [14][15][16][17] with the aim of transitioning to green nuclear power have been sufficiently developed; there are also counterarguments [18], quantitative answers to which can be obtained through appropriate research. In any case, this concept should be considered in conjunction with the economy and the key problems of nuclear power to ensure its sustainable development and closure of the fuel cycle.…”

Possible prospects for thermonuclear research in the first half of the 21st century and their implementation in the practical sphere of domestic energy are discussed. It is concluded that thermonuclear research can be and already acts as a powerful driver of scientific and technological progress, a mechanism that stimulates the development of high-tech segments of the country's economy, and a possible element of the nuclear energy of the future. This article was prepared based on the materials of a report presented at the General Meeting of RAS Members on December 8, 2020.

The design of the demonstration fusion neutron source (DEMO-FNS) demonstration fusion–fission hybrid facility is carried out at the National Research Center ‘Kurchatov Institute’ in Russia. For the implementation of the DEMO-FNS project, it is important to assess the effect of the fast neutron spectrum on radiation-induced damage to the device materials, primarily the materials of the first wall, which is the most problematic unit of the device. Due to the lack of real hybrid fusion devices, the study can only be carried out using computer simulations of the experiment. A computer simulation using the Monte Carlo method was carried out to calculate the developed three-dimensional full-scale model of the DEMO-FNS reactor with a blanket for the transmutation of minor actinides. The MCNP-4 code was used with cross-sections from the FENDL-2.1 and ENDF/B-6 files, as well as with cross sections for calculating radiation displacements. The neutron spectrum in the first wall of DEMO-FNS was determined at the power of a volumetric deuterium–tritium neutron of 1.42 × 1019 n s−1. It was found that beryllium as a plasma-facing material has too short lifetime under the neutron load on the first wall and divertor plates of DEMO-FNS. The replacement beryllium to tungsten is problematic and requires special study. Copper alloys have sufficient resistance to the effects of neutron radiation of DEMO-FNS for one full power year, but will require several replacements when operating the device for more than 10 years. The steels used in fast reactors can meet the operational requirements of the first wall of DEMO-FNS. To solve the problem of choosing materials for the first wall of DEMO-FNS, new experimental researches on changes in the physical properties of these materials in the fast neutron spectrum are needed.
