storage-barriervia NHK World / February 16, 2014 / The operator of the damaged Fukushima Daiichi nuclear plant says officials have found water leaks at 7 locations in a barrier that surrounds tanks holding contaminated water.

Tokyo Electric Power Company officials said they confirmed on Sunday that water had leaked from the barrier near the Number 4 reactor. It’s one of 30 barriers in the compound.

The officials said the amount of the leak was about 19.2 tons, which they believe seeped into the ground.

They detected 23 becquerels per liter of radioactive strontium 90 in water still inside the barrier.

The level is below the national standard for the discharge of contaminated water into the sea, but is 2.3 times the standard for discharging from the barriers.

Heavy rains last October caused the barriers to overflow. That prompted the utility to raise the height of the barriers.

The officials said the leaks occurred at connections between steel plates used to raise the height of the barrier and from where piping was installed in plates.

They said they are investigating why the leaks are concentrated at the barrier.

  1. I find it interesting that it was “Officials” and not TEPCO that found the leaks especially with their sparkling reputation for honesty.
    The clock is still ticking and things still continue to deteriorate.

  2. What is the point in having a “barrier” if the water just “seeps into the ground?
    And these guys want to start up reactors again !!

  3. “Heavy rains last October caused the barriers to overflow. That prompted the utility to raise the height of the barriers.”

    Hmmm It seems their original design did not take into account RAIN???
