Russia Leads Global Nuclear Reactor Construction Market

State-owned Russian firm leads international nuclear construction despite declining revenues from Western sanctions.

Russia’s state-owned Rosatom corporation dominates global nuclear reactor construction, according to a report presented in Berlin on Tuesday. According to a report, Rosatom was building 28 of the 73 nuclear reactors under construction worldwide as of July 1.

Twenty-one of those 28 reactors are being built outside Russia. The corporation holds the title of the world’s largest supplier of nuclear technology.

Rosatom or its subsidiaries maintain major roles in nuclear projects across eight countries.

Revenues from the company’s international business dropped following Western sanctions. Governments imposed those economic penalties after Russia invaded Ukraine.

Despite the sanctions, Rosatom maintains close working relationships with specific Western companies. French firms retain particularly close ties with the Russian nuclear giant.

China continues to drive the global expansion of nuclear power capacity, according to the Berlin report. A total of 411 nuclear reactors operated worldwide as of July 1. Those active units possess a combined capacity of 374.7 gigawatts (GW).

The average age of reactors in the United States, France, Russia, South Korea, and China now exceeds 32 years.

Nuclear power’s share of global electricity generation continues to decline. The technology accounted for 8.8% of global electricity generation last year.

Coal and natural gas outpace nuclear power significantly in the global energy mix. Coal generated 32.6% of the world’s electricity last year, while natural gas contributed 21.9%.

Renewable energy sources combined generated more than one-third of the world’s electricity. Hydropower played a major role among renewables, contributing 13.9% to the global total.
