Much was made at the time and since about the placement of the emergency diesels low in the plants, at the level of bedrock – causing them to be flooded and useless when the plant was inundated with water (and a great deal of debris) from the tsunami.  The fact is that the diesels were mandated by Japan’s regulator to be mounted on bedrock for earthquake protection when the plant was built; roof mounted, “air cooled” diesels were added to the
