Excellent post. It's about time the qualified professionals at TEPCO released a verifiable synopsis of what actually happened at the Fukushima installation. They included a quantitive report for their complete system. Those buttheads in the media and the anti-nukers will still demagogue this incident for their own self interest. But, the fact remains....the operators and the plants performed magnificently under the most severe physical circumstances that could be imagined. Now, maybe the press will turn its attention to the horrendous loss of life and property caused by the real dangers....earthquake and tsunami.

> At approximately 6:14 am, March 15th, the extraordinary sound was

>*Unit 3
> At 6:50 am, March 14th, while water injection to the reactor was under

>[Others]
>Please do NOT touch cut-off electric wires.
>In order to prevent fire, please make sure to switch off the electric
>appliances such as hair drier and to shut down the breaker of distribution
