They too were willing to save money and design to a level all the experts thought were adequate. As often happens, the experts were just wrong. It will likely be the most expensive cleanup in history.
Fukushima, they knew the danger. They had already re-located some of the engine generator sets up hill (units 4-6). And the gensets were setup to allow cross connecting so that they could feed everything. The problem was they had not yet moved the switchgear on units 1-3. Once the switchgear went underwater, there was no way to feed power to the cooling water pumps.

Fukushima-II, the gensets were inside the water tight building.
