Nov. 2 — According to TEPCO general manager Junichi Matsumoto, “There’s been no large-scale or sustained criticality.”

However, Bloomberg quotes an expert who isn’t as confident: “Melted fuel in the No. 2 reactor may have undergone a sustained process of nuclear fission or re-criticality.” -Tetsuo Ito, the head of Kinki University’s Atomic Energy Research Institute.
