Title: Fukushima probes leave questions

the Diet-appointed independent panel, imbued with stronger investigative authority [than the other probes], suspects the offshore quake, which preceded the tsunami by 40 minutes, severely damaged some of the three reactors.

This again raises serious questions about the quake resistance of older reactors across the country, as well as most of the antidisaster measures the government has adopted since the Fukushima crisis started.

Most of the Fukushima-inspired safety measures adopted for reactors focus on the tsunami risk, because Tokyo Electric Power Co. and the government played down the impact of the quake, which was rated a strong 6 on the Japanese intensity scale to seven at the Fukushima plant.

“We concluded that Tepco was too quick to cite the tsunami as the cause of the nuclear accident and to deny that the earthquake caused any damage. We believe there is a possibility the earthquake damaged equipment needed for ensuring safety,” the Diet panel headed by Kiyoshi Kurokawa, the University of Tokyo professor emeritus, said July 5.

The Diet panel argued that the quake might have knocked out some of the emergency diesel generators and damaged pipes carrying coolant to the cores.

    People here have been saying this since 3/11.

    Glad that reality is FINALLY starting to prevail…

    YES were were correct, this will be THE smoking gun issue…
    See: March 12th, 2011 – Chairman of Japan Atomic Energy Commission’s high-level report on Fukushima Daiichi sequence of events

    "It was reported at 15: 35 that the Reactor Building of 1F1 was ruptured after a rather strong earthquake with the sound of explosion and that the level of radiation at the site boundary was suddenly doubled from 500 micro Sv/hr of that after venting operation to 1 mSv/hr. The explosion is considered due to explosion of hydrogen leaked from the primary coolant boundary caused by the impact of the earthquake."

    The tsunamis were deadly, but they were just water burps from an even greater natural disaster…a huge earthquake. Yes it may have been an earthquake that happens once a century in the world, but nuclear fuel lasts scores of millennia. The toxic waste material patiently sits and waits for an accident to happen.
