The pool that sits at the top of the plant's No. 4 reactor, which suffered an explosion and fire early in the crisis triggered by last year's massive earthquake and tsunami, remains one of biggest risks due to its vulnerability to earthquakes. Ikko Nakatsuka, vice-minister of reconstruction who saw Unit 4 pool during his plant tour in April, said earlier this week that the building wasn't tilted and the pool had sufficient water inside to keep rods safely cooled, denying the rumors. A worst case scenario produced by the head of the Japan Atomic Energy Commission two weeks after last year's accident warned that meltdown at Unit 4, along with all Fukushima reactors, would require evacuation of 30 million people from the greater Tokyo area.
