The Russian Federation leads the world in the construction of nuclear reactors, according to the State of the World Nuclear Industry report.
According to the study, the Russian state corporation Rosatom is the largest supplier of nuclear technologies. Of the 73 reactors built in the world as of July 1, 2026, 28 are being built with the company's participation. Furthermore, 21 of them are located outside of Russia.
According to the report, Rustom or its subsidiaries are involved in the construction of nuclear facilities in Bangladesh, China, Egypt, Hungary, India, Iran, Turkey and Uzbekistan. However, the corporation's income from foreign projects has dropped significantly due to Western sanctions imposed on Moscow after the start of the Russian war against Ukraine.
At the same time, the main growth engine of the global nuclear energy industry today is China: there the capacities of nuclear power plants are actively increasing and the number of reactors being built within the country is increasing.
As of July this year, 411 reactors were operating worldwide with a total capacity of 374.7 gigawatts (GW). At the same time, the share of nuclear energy in global electricity production continues to decline. In 2025 it amounted to 8.8%, while coal accounted for 32.6%, natural gas - 21.9%, oil - 2.2%.
