TOKYO – Japanese government regulators say they'll conduct their first investigation into the country's nuclear crisis to address key unanswered questions.
Several groups have published findings of their own investigations into the Fukushima Dai-ichi nuclear plant, which was ravaged by the March 2011 earthquake and tsunami. Previous investigations have largely blamed the disaster on botched crisis management, government-industry collusion and the tsunami.
But questions remain, and experts still suspect that the quake, not the tsunami, may have triggered a meltdown at the plant. This is a key point that could affect anti-quake measures at nuclear facilities nationwide.
The Nuclear Regulation Authority said Wednesday that its investigation will start by the end of April and could take decades because parts of the plant are in such poor condition.
