I live not that far away from a (now decommissioned) nuclear power station, and from what I keep hearing from old people who lived through the time of its construction, there was a lot of lenience and looking the other way involved. For instance, (A very persistent) Rumor has it, that many houses built in the nearest town around that time, had their foundation, cellar walls, and floors poured with the heavy anti-radiation concrete intended for the power station, because quite a number of the concrete trucks destined for the containment building (which is made of an awful lot of concrete) did conveniently take a wrong turn and ended up at the wrong construction site for some odd reason. (Maybe the drivers getting a case of beer for every detour they took might have been a factor)
