Why would fuel be removed from a reactor?
Testing “potency” since it’s new to the country?
Installation into a war-head?
Or do they know an Israeli attack on their facilities is imminent?
Unless this is for a reactor repair its a very serious matter. Plutonium extraction from reactor fuel is easy. The fact that they didn’t wait the entire fuel life cycle indicates a likely immediate sprint toward nuclear capabilities.
Usually you have to wait quite some time for the fuel to cool down prior to moving it, but for a desperate country with eager martyrs they may not wait.
Let’s hope this is a repair. If that fuel starts to leave the building there will be airstrikes.
