Scrutiny of the 150 hours of teleconferencing footage recorded by Tokyo Electric Power Co. in the initial days of the March 2011 meltdowns at the Fukushima No. 1 plant shows that crucial decisions were being made hastily.

Tepco on Monday started letting journalists view the footage — 50 hours with audio and another 100 without — of the first five days of the crisis.

The video shows top executives discussing the "evacuation" of workers from the nuclear plant. But it didn't give definitive clues on one critical question — whether Tepco was abandoning the plant for good amid the radioactive fallout.
