Center Calling For Resignation of Tokyo Electric Power Company President
The Center is calling for sealing the Fukushima site and has been calling for a sarcophagus to be placed over reactors 1, 2, 3 & 4. Tepco management should have begun sealing the facility just as soon as they lost control of cooling the reactors. Instead, they are unnecessarily sending workers into the facility in some futile attempt to salvage the facility.
The Center is also calling for Japanese Prime Minister Naoto Kan to resign.
