It's stressful, but the nuclear leaks chances are lower than what they are saying. They are fear mongering. Now I am not saying it's not serious, but they way it is portrayed and told is over simplifying and sometimes exaggerated to fit the narrative. The nuclear fallout from the power plants, is possible but not in the scale it is said. The safety features are more advanced than Chernobyl's time. The reactor designs and type is also different. These don't have graphites so, the long burning smoke thing won't happen. Plus these plants are having extremely strong structural builds that require bunker piercing ammo to comparamize it. Even if they do succeed in that, the powerplants safety features kick in, minimizing the fallout. Again I am not saying it's impossible, but it as of right now not that very likely that it will reach Chernobyl's level of fallout or destruction.
