March 11th 2017 will be the 6th anniversary of the ongoing Fukushima disaster.
Radiation Free Lakeland invite people to join them in a vigil to remember and to send a message to the nuclear industry that no amount of electricity is worth the kind of damage a nuclear accident inflicts on our sea, air, soil, fresh water and on our children.
Springfields (Toshiba/Westinghouse) made the fuel for the first nuclear disaster, the Windscale Fire in Cumbria. Springfields continues to make nuclear fuel from uranium for ALL the UK’s nuclear power stations. Springfields also supplies 12 countries worldwide with nuclear fuel including Japan.
**Please Join us on March 11th to Remember Fukushima**
6 years later, the catastrophe at Fukushima is still far from being resolved, still ongoing. 3 reactor core meltdowns still releasing radioactive nanoparticles into the open skies, contaminated water still leaking continuously into the Pacific ocean, plus partially decontaminated water also been dumped into the ocean.
All available information and figures controlled by Tepco and the Japanese government, with no independent party allowed to verify the veracity of the given information. A massive permanent public relations campaign of disinformation and denial, to brainwash the Japanese population and the whole world that everything is now under control and ok, denial of the radiation risks for the people health, economics being the Japanese government priority, not the population health protection. Evacuated persons coerced to return to live with high radiation in their previously evacuated townships. So that Japan would seem safe, clean and beautiful to welcome the Tokyo 2020 Olympics.
If Fukushima taught us one thing it is that people should not expect the government to protect them nor corporations to be held responsible in time of nuclear disaster.
This written article is based on officially released data by Tepco and the Japanese government, therefore all the figures and claims should be therefore taken with a pinch of salt. Always keep in mind that the officially released information does not really teach us the essential about the still ongoing catastrophe and about its victims getting more abandoned than ever.
Key figures for the sixth anniversary
As we approach the sixth anniversary of the disaster, here are some key figures as they appear in the media and official sites.
The reactor vessel was empty on March 11, 2011, and there was no melting of the core, but a hydrogen explosion destroyed the reactor building. Since December 2014, the reactor fuel pool has been emptied and the work is stopped.
Reactor # 3
There was a core meltdown and a hydrogen explosion destroyed the reactor building. All debris from the upper part were removed using remotely operated gear. A new building that will cover the whole and allow to empty the fuel pool is being assembled. The dose rate is so high that the work is more complex than expected and the site has fallen behind.
Reactor # 2
There was a core meltdown, but the reactor building is whole. Tepco did not begin to remove the spent fuel from the pool, but attempted to locate the corium, this mixture of molten fuel and debris, by various means. The dose rates inside the building are such that it is impossible to work on it. In the containment, record levels were observed. Even the robots that were sent there did not resist long.
Reactor # 1
There was a core meltdown and a hydrogen explosion destroyed the reactor building. This building was covered with a new structure in 2011, which was completely dismantled in November 2016. Tepco will begin to remove the debris from the upper part of the reactor and then rebuild a new structure to empty the fuel pool.
This makes a total of 252 m3 / d. This water is strongly contaminated and infiltrates into the basements of the reactor and turbine buildings where it mixes with the ground water that floods these basements.
To reduce radioactive groundwater leakage into the sea, Tepco pump water upstream before that water is contaminated by the reactors and then rejects it directly into the ocean. It has also built a barrier along the shoreline and pumped groundwater at the foot of the reactors. Part of this water is partially decontaminated and dumped into the ocean. Another part, too contaminated, is mixed with the water pumped in the basements of the reactors to be put in tanks after treatment, waiting for a better solution.
Tepco announced that it had already processed 1,730,390 m3 of contaminated water, which generated 597 m3 of radioactive sludge. Part of this is used for cooling and the rest is stored in tanks. According to the company, the stock of treated or partially treated water amounts to 937,375 cubic meters, to which must be added the 52,200 cubic meters of water in the basements of the reactor and turbine buildings. There are nearly a thousand tanks to keep this water that 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 damaged reactors to reduce infiltration and dispersal of polluted water, but this is not as effective as expected. The Nuclear Regulatory Authority, the NRA, seriously doubts the effectiveness of this technique, which it now considers as secondary. It can be seen on this graph, where the drop in the volumes of water to be stored each day is not very high. The ice does not take place, where the underground currents are strongest. Official data on freezing of the ground. About half of the workers on the site are there because of the contaminated water. http://www.tepco.co.jp/en/nu/fukushima-np/handouts/2017/images/handouts_170209_02-e.pdf
At the Fukushima Daiichi nuclear power plant
From March 11, 2011, to March 31, 2016, 46,956 workers were exposed to ionizing radiation at the site of Fukushima Daiichi, including 42,244 subcontracted workers. It is the subcontracted workers who take the highest doses, with an average of between 0.51 and 0.56 mSv per month between January and February 2016. It is between 0.18 and 0.22 for employees of Tepco.
There are also 1,203 people who have a higher limit to continue entering the site. Their average cumulative dose since the beginning of the accident is 36.49 mSv and the maximum value of 102.69 mSv.
On April 1, 2016, all measures were reset. Thus, 174 workers who have exceeded the dose limit will be able to return. Since that date, up to 31 December 2016, 14,643 workers have been exposed to ionizing radiation at the site of Fukushima Daiichi, of which 13,027 are subcontracted workers (89%). Subcontracted workers take the highest doses. Among them, it is not known how many were already exposed to radiation before April 1, 2016.
• There were workers of Brazilian origin who did not speak good Japanese and did not always understand the instructions of radiation protection. The Embassy of Brazil reacted and protested.
• While progress has been made in working conditions on the site, with the construction of a building dedicated to reception and rest, equipped with a canteen and a mini market, there are still problems thanks to cascade subcontracting.
• 3 workers had their cancer recognized as occupational disease: two leukemias and one thyroid cancer. One filed a complaint against Tepco and Kyûshû Electric.There are 15 cancers in all of these workers, including 8 cases of leukemia.
Radioactive pollution mapping
• The latest aerial mapping of radioactive pollution around the Fukushima Daiichi plant dates from 2015 and is available online on the dedicated site: http://ramap.jmc.or.jp/map/eng/
This new map shows the areas still evacuated and an average decrease of 65% of the ambient dose rate compared to what was measured in autumn 2011. The radioactive decay is responsible for a drop of 53%. The remainder is due to the leaching of soils and, in some places, to decontamination work.
The decontamination of evacuated areas is the responsibility of the government. Elsewhere, where the external exposure could exceed 1 mSv / year, it is the municipalities that have to deal with it.
• In non-evacuated areas, 104 townships were affected, but with the natural decline in radioactivity, the number became now 94. A map is given on page 14 of this document. In Fukushima, 15 out of 36 municipalities have been completed.
• For the interim storage facility, which is expected to contain approximately 22 million cubic meters of waste over 1,600 ha or 16 km2 around the Fukushima Daiichi plant for a maximum of 30 years, the government signed a contract with only 633 landowners (26.8%), for a total area of 287 ha (or 2.87 km2), or just 17.9% of the total area.The authorities want to reuse these soils when they have fallen below the limit of 8 000 Bq / kg for cesium. http://josen.env.go.jp/en/pdf/progressseet_progress_on_cleanup_efforts.pdf
• Japan conducts a census of its population every 5 years. The last two took place in 2010, just before the disaster and in 2015. As of October 1, 2015, the population of Fukushima province decreased by 5.7% compared to 2010 (115,000 fewer people) Miyagi of 0.6% and that of Iwate of 3.8%.
This census is based on the persons actually present and not on the registered persons. Thus, in the townships of Namie, Futaba, Okuma and Tomioka there is zero inhabitant.
The population of Kawauchi, where the evacuation order was partially lifted in 2014, the population decreased by 28.3%. In Naraha, where the evacuation order was fully lifted in September 2015, the population decreased by 87.3%.
Some townships hosting displaced persons have seen their population increase.
In all of Japan, the number of inhabitants decreased by 0.7% (- 947,000) in five years and was 127.11 million by 1 October 2015. The number of inhabitants increased in Tokyo (+2, 7%), Saïtama and Aïchi prefectures. The biggest decline was in Akita prefecture (-5.8%), which was not affected by the triple disaster. Fukushima prefecture has the second biggest drop, with -5.7%.
• Of the 54 nuclear reactors operating before the nuclear disaster, 6 were partially or completely destroyed at the Fukushima Daiichi plant. 6 others, too old, were stopped definitively. So there are only 42 nuclear reactors left in Japan.
Only 26 of them have applied for restart authorization and only 12 reactors have been granted a restart authorization. Two reactors at the Sendai power station in Kagoshima prefecture generate electricity to power the grid. A third is in operation at the Ikata power station in Ehime prefecture, both in southern Japan..
