Russia is temporarily limiting exports of enriched uranium to the U.S., creating potential supply risks to utilities operating American reactors that generate almost a fifth of the nation¡¯s electricity.

The Russian government didn¡¯t provide details regarding the restrictions or their duration in a Friday statement on Telegram. Utilities tend to make purchases well in advance, so any impact is unlikely to be immediate.

As Russia¡¯s prolonged war in Ukraine has made it increasingly unpopular on the world stage, the nation has repeatedly signaled a willingness to use its vast energy resources as geopolitical bargaining chips. Russia also told Austria on Friday that it¡¯s throttling gas supplies, interrupting a six-decade supply agreement currently covering 80% of demand because of a legal dispute.
