barriers around the nuclear reactor at this plant, did do some damage and we're also worried about a loss of energy, if electricity to these plants are cut off, then the pumps system goes down, the water won't be allowed to cool the reactors and you could be looking at a fukushima-style meltdown of these facilities. and then you have the problem of the spent fuel rods in cooling pond, unprotected, large structures outside near the power plant, if those ponds leak, then the water drained, again, you will have a melt down, and it leaves clouds of radio active debris that could contaminate hundreds, even thousands of square kilometers. this is a severe risk. this is why there are international conventions against doing this. this is why no one has ever attacked a nuclear plant before. and here, the russians are shelling it. heavy caliber machine gun power, sending flares into the facility, i can't overstate what a severe danger this presents to the people of ukraine.
