Has this happened? Ukrainian civilians bombed?
The reactors that aren't infamous have already had all fuel removed. The one that was scattered all over the countryside has plenty of highly radioactive debris but you can't realistically pull out material for a dirty bomb. Terrorists would have better luck stealing cobalt 60 sources and spreading that through a city than trying to break into the new safe confinement, break into the sarcophagus, find a suitably large amount of highly radioactive material, somehow break it into pieces and truck it out of the area, etc.
Terrorists aren't going to try to use the war as cover to sneak into Chernobyl regardless of Russian troop presence.
Please… Russians will just use it for their propaganda as a support to the claim that Ukraine was working on nuclear weapons.

I'm totally condemning the Russian actions, but in this particular case they may be acting somewhat responsibly. Unlike with the bombing of civilians or the whole damn war in the first place!
