If they really want nuclear energy for civilian use, why uranium? The next generation nuke technology are thorium/molten salt reactors. Among its many improvements over uranium reactors is the fact it can’t be weaponized. Call their bluff. Tell ‘em we whole heartedly support their civilian nuke energy program. Offer to fill whatever technological gaps they may have regarding thorium reaction technology. Offer to help build them. If they still insist on uranium, we and everyone else will know exactly what they really want at that point.
