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

Radiation at Fukushima rising to highest level since 2011 meltdown
“[…] recent measurements showing 53,000 Rem per hour (deadly to humans within a minute or less, at close range, in the absence of radiation shielding), or higher, radiation dose rates in the melted down Unit 2 reactor at Fukushima Daiichi, Japan.”
Emergency storage tanks contain “800,000 tons of highly radioactive water … because every day they pour a hundred tons of water on each of these three melted down cores and sometimes they lose those tanks. They leak, they overflow, so it is an ongoing catastrophe,” says Kevin Kamps, radioactive waste monitor at Beyond Nuclear,
“There are many shoes that could still drop at Fukushima Daiichi. One of the ones is the high radioactive waste storage pools that aren’t even inside radiological containment. They don’t have all of that spent nuclear fuel transferred to a safer location in a couple of the units still. If something were to go wrong with that – those would be open air releases of very high-level radioactivity.
“The prime minister at the time the catastrophe began, Kan, had a contingency plan to evacuate all of Northeast Japan – up to 50 million people. It was predominantly because of those storage pools. We’re still in that predicament- if one of those pools were to go up in flames. As Tokyo plans to host the 2020 Olympics and bring in many millions of extra people into this already densely populated area –it is not a good idea.”
