Nuclear energy on the 21st century in climate limits context

Nuclear energy system development in the current century is considered in the article. The importance of this issue both for the future and for the choice of ways to solve current energy problems is high, which is largely due to the increasing environmental restrictions. Nuclear energy using promises negative impact of the energy system on enviroment minimizing. However, the danger of radiative pollution of the environment is a significant deterrent to the large scale industry development. The article discusses the problem of the nuclear power system development in the variant of the coordinated use of fission reactors for energy production and hybrid thermonuclear reactors for production of artificial fuel from thorium raw materials for fission reactors. Estimates are presented to substantiate the preferences of the structure of the nuclear power system under consideration.
