Report on Earthquake Damage to Japan’s Kashiwazaki-Kariwa Nuclear Power Facility

In the early hours following the July 16 earthquake in Japan’s Niigata Prefecture, when Tokyo Electric Power (TEPCO) was reporting only a transformer fire and spill of 1.5 liters of radioactive water, NIRS criticized TEPCO for being slow to report information and told the Associated Press that we were waiting “for the other shoe to drop.”

That sound you hear is the rumble of an entire shoe factory tumbling to the ground.

It is now clear that the damage to the world’s largest nuclear power facility was far greater than initially reported and that radiation releases were also far greater than reported. Indeed, it appears that radiation releases are continuing today (July 19, 2007). According to a report from Bloomberg

News (http://www.bloomberg.com/apps/news?pid=20601087&sid=aCWh.1vTk3_Y&refer=home), 402

million Becquerels of radioactivity already have been released, although this government-supplied figure likely understates the reality, as radiation apparently continues to be released into the environment.

According to the Associated Press (http://www.pr-inside.com/a-look-at-problems-found-at-r174712.htm)

on July 17, damage to the reactors was extensive. The AP found the following problems listed at that time:

A list of malfunctions at the seven-reactor Kashiwazaki-Kariya nuclear power plant in northwestern Japan following a powerful earthquake this week

  • *

    Fire at an electrical transformer facility.

    • *

      1,200 liters of water containing radioactive material leaked into sea.

    • *

      About 100 barrels of radioactive waste knocked over in storage facility.

    • *

      Duct knocked out of place in major vent; possible leak of radioactive cobalt-60 and chromium-51

from five of the plant's reactors.

  • *

    Water leak inside buildings housing all seven reactors.

    • *

      Malfunctioning of water intake screening pump at two reactors.

    • *

      Blowout panel knocked down at turbine buildings at two reactors.

    • *

      Oil leak from low-activation transformer waste oil pipes at two reactors.

    • *

      Loss in water-tight seal at reactor core cooling system.

    • *

      Water leaks from diesel generator facility, burst extinguisher pipe, burst condenser valve and

filtration tank.

  • *

    Broken connections and broken bolt at electric transformer.

    • *

      Loss of power at control center for liquid waste disposal facility.

    • *

      Oil leaks from damaged transformer and magnetic transformer facility.

    • *

      Oil leak at reactor water supply pump facility.

    • *

      Disrupted electrical connection at magnetic transformer facility.

    • *

      Cracks in embankment of water intake facility.

    • *

      Air and oil leaks at switching stations.

    • *

      Land under parts of plant turned to mud in quake-caused process known as liquefaction.
