Russia Is KingMuch has changed since the 20th century. The United States is no longer the predominant supplier of reactors; that title is currently held by Russia. Of the 72 nuclear reactors planned or under construction outside Russia’s borders in 2018, more than 50 percent involved Russian companies, and around 20 percent involved Chinese ones; fewer than 3 percent were being built by U.S. companies. China is especially well positioned to play a large role in the global nuclear energy regime given its gargantuan domestic reactor build program. In just over a decade, China looks likely to overtake the United States as possessing the world’s largest reactor fleet.
