> The primary failure at Fukushima was a sea wall too low for the tsunami that occurred Loss of emergency electricity for the reactors. Needs for large amounts of electricity for cooling of reactors and spent fuel pools. No quick electricity from the outside for the reactors. Hydrogen explosion damaging the building. Cooling only possible with water from the outside. Structural damage due to water on the building. Spent fuel pools high in the building - hard to reach. Lots of spent fuel on the site, because a lack of storage sites. Radioactive water leaking to the environment. Possibility of severe damages on the building by further earthquakes... There were many many problems with the site.
