Via The Globe and Mail: ‘This is serious,’ Fukushima chief shouted after explosion: videos. Excerpt:
The emergency command centre at Japan’s stricken nuclear plant shook violently when hydrogen exploded at one reactor and the plant chief reacted by shouting, “This is serious, this is serious,” reveal videos of the crisis as it happened last year.
Tokyo Electric Power Co. initially refused to release the videos, but the company is now under state control and it was ordered to do so. The footage seen Monday was mainly of teleconferences between company headquarters in Tokyo and staff at the Fukushima Dai-ichi nuclear plant, after the March 11, 2011, tsunami caused critical damage to its reactors.
In the videos, then-plant chief Masao Yoshida complained about phone calls to the prime minister’s office not getting through and showed frustration as he fought the government’s nuclear safety officials interfering with technical suggestions that didn’t fit the plant’s conditions.
Around 11 a.m. on March 15, Mr. Yoshida screamed to officials at Tokyo headquarters: “The headquarters! This is serious, this is serious. The No. 3 unit. I think this is hydrogen explosion. We just had an explosion.”
In the video’s background, other officials shout questions, asking for radiation levels and other data.
The videos also included conversations showing communication problems between the plant and the government, workers’ lack of knowledge in emergency steps and delays in effort to inform outsiders about the risks of leaking radiation.
The Japan Times Online also has the story, but I still haven't found any links to the videos.
