Fukushima: 6 Years of Catastrophe and Counting

Unending Nightmare: Fukushima Daiichi Nuclear Disaster

Key Facts and Figures as Fukushima Disaster Enters 7th Year

  • 3 Reactor core meltdowns continue releasing radioactive nanoparticles into the environment.
  • Contaminated water is still leaking continuously into the Pacific ocean
  • Partially decontaminated water is being dumped into the ocean.

<span “>Contaminated Water
Tepco injects a total of 252m³ of water each day into reactors 1, 2 and 3 to cool the corium.http://www.tepco.co.jp/en/press/corp-com/release/betu17_e/images/170217e0101.pdf.

The strongly contaminated water infiltrates basements under the reactor and turbine buildings where it mixes with the ground water that floods those areas.

Tepco is also pumping an additional 135 m³ of contaminated water and 62 m³ of groundwater into the basements of the reactors and turbine buildings daily, in addition to the water injected for cooling. A total of 197 m³ is accumulated daily in tanks after treatment. It is more when it is raining, and more still during the typhoons. http://www.tepco.co.jp/en/nu/fukushima-np/handouts/2017/images/handouts_170213_01-e.pdfTepco

To keep about 2 million cubic meters of contaminated and processed water and hundreds of tons of sludge, Tepco has erected about 1,000 shoddily constructed holding tanks hat occupy almost the entire plant site. http://www.tepco.co.jp/en/press/corp-com/release/betu17_e/images/170217e0101.pdf 

Since March 2016, Tepco has been trying to freeze the ground around the stricken reactors to reduce infiltration and dispersal of radioactive water, but this has proved far less effective than expected. http://www.tepco.co.jp/en/nu/fukushima-np/handouts/2017/images/handouts_170209_02-e.pdf

  1. Sam M. said

    Court holds TEPCO, govt liable for Fukushima nuclear disaster

    https://www.washingtonpost.com/

    A court held Japan’s government and a utility liable on Friday for neglecting tsunami safety measures at the Fukushima nuclear plant and ordered them to pay more money to dozens out of the thousands of people who fled radiation released during the March 2011 disaster.

    The ruling is the first from about 30 lawsuits filed by thousands of evacuees and could set a precedent for the other cases. About half of the 150,000 people forced to leave their homes still cannot return, six years after a massive earthquake and tsunami destroyed the plant and caused reactor meltdowns.

    The Maebashi district court ordered the national government and Tokyo Electric Power Co. to pay damages ranging from 70,000 yen ($620) to 3.5 million yen ($31,000) to 62 plaintiffs, or 38 million yen ($336,000) altogether, in addition to the compensation TEPCO has already paid them. The rest of the 137 plaintiffs in the case were not awarded additional compensation.

    The court said the disaster was preventable and that TEPCO ignored safety steps despite knowing of the tsunami risk, while the government failed to oversee the utility. Even though TEPCO deserved severe blame because of its negligence, that does not lighten the government’s responsibility, the court said, adding that they should split the cost of the damages.

    The court upheld the plaintiffs’ argument that TEPCO could have foreseen a massive tsunami as early as 2002, when a government panel predicted a 20 percent chance of a magnitude 8 earthquake triggering a tsunami along the Fukushima coast within 30 years. TEPCO also ignored another chance to implement safety measures in 2008 when a government study group warned of a major tsunami triggering a power loss at the plant.

    At the Fukushima plant, the reactor buildings were not watertight and backup power generators were stored in the basement. The tsunami that swept into the plant on March 11, 2011, knocked out the reactors’ cooling system and destroyed the backup generators that could have kept it running and kept the nuclear fuel stable.

    In the ruling, Judge Michiko Hara said TEPCO should have moved the generators to higher floors.

    Government, parliamentary and private investigations have blamed complacency over safety, inadequate crisis management skills, a failure to keep up with international safety standards, and collusion between regulators and the nuclear industry.
