Russia’s state nuclear corporation Rosatom has refuted reports that state-owned uranium company Tenex is warning US customers that Moscow may pre-emptively bar exports of its nuclear fuel to the US if lawmakers in Washington pass legislation prohibiting imports starting in 2028.

Bloomberg, citing people familiar with the matter, said Tenex’s US subsidiary has told some electric companies in the US to prepare for such an outcome.

However, Rosatom said information regarding the alleged warnings of a potential pre-emptive ban on enriched uranium supplies is incorrect.
