Russia’s state-owned uranium supplier Tenex has notified US customers they have 60 days to secure a waiver exempting them from a law recently signed by President Joe Biden that bars imports of the company’s nuclear fuel.

The force majeure notice seen by Bloomberg was sent to utilities including Constellation Energy Corp., the largest US nuclear plant operator, Duke Energy Corp. and Dominion Energy Inc., according to a person familiar with the matter who wasn’t authorized to speak publicly. Constellation declined to comment and Duke and Dominion didn’t respond to a request seeking comment.
