This is normal… has been happening for many many years if you live within a very very close radius. preventative measure IF anything at all were ever to happen. I am nukeopsanon, it would take all out ugly war for anything to happen to any of these sites, trust me on that… this is concernfagging.
understandable. good idea to have in a b.o.b. will agree with you there for sure. but yes, common practice. without going too deep, the design mods in place post fukushima allow venting if the absolute worst case happens, which would lightly dose the surrounding immediate population but contain the mess inside primary containment, saving the surrounding earth from disaster. I live less than 2 air miles away from mine and knowing what I know, am comfy as hell here.
