Russia’s state-owned Rosatom corporation is the world’s largest supplier of nuclear technology and is reported to be building 28 of the 73 nuclear reactors under construction worldwide as of July 1, according to a report cited by Yahoo.
That dominance places the Russian enterprise at the center of international energy infrastructure, even as Western sanctions following the invasion of Ukraine weigh on its overseas revenue streams. According to the World Nuclear Industry Status Report presented in Berlin on Tuesday, 21 of those 28 Russian-backed projects are located outside Russia.
Rosatom or its subsidiaries maintain major roles in nuclear projects spanning Bangladesh, China, Egypt, Hungary, India, Iran, Turkey, and Uzbekistan. Despite financial pressure from Western penalties, the corporation retains close working relationships with several Western companies, particularly in France.
China continues to drive the wider global expansion of nuclear power capacity. Globally, 411 nuclear reactors with a combined capacity of 374.7 gigawatts were operating as of July 1.
The average age of reactors in the world’s five leading nuclear countries—the United States, France, Russia, South Korea, and China—now exceeds 32 years.
At the same time, nuclear power’s overall share of global electricity generation continues to decline. Last year, nuclear energy accounted for 8.8% of global electricity production, trailing far behind coal at 32.6% and natural gas at 21.9%.
Renewable energy sources combined now account for more than one-third of global electricity generation. Hydropower plays a particularly vital role within that green sector, contributing 13.9% to the global total.
