Very high radiation, little water in Fukushima reactor
The data collected Tuesday showed the damage from the disaster was so severe, the plant operator will have to develop special equipment and technology to tolerate the harsh environment and decommission the plant, a process expected to last decades.
The other two reactors that had meltdowns could be in even worse shape. The No. 2 reactor is the only one officials have been able to closely examine so far.
Tuesday’s examination with an industrial endoscope detected radiation levels up to 10 times the fatal dose inside the chamber. Plant officials previously said more than half of the melted fuel has breached the core and dropped to the floor of the primary containment vessel, some of it splashing against the wall or the floor.
