Tokyo Electric Power Co. (TEPCO)—the company that runs the Fukushima nuclear plants—says that 70% of the fuel rods have been damaged on the reactor 1 and 33% have been damaged on reactor 2. "The reactors' cores are believed to have partially melted" says the Japanese news agency Kyodo. Sadly, this confirms the judgement of international experts, who criticized Japan for underplaying the crisis.
