The Fukushima nuclear waste crisis is a human rights violation

Traditional early morning Japanese breakfast, briefing on objectives, equipment check and drive into the beautiful mountainous forests of this region: this is the daily routine that will allow us to complete our latest investigation into the radiological status in some of the most contaminated areas of Fukushima prefecture.

But there is nothing normal about the routine in Fukushima.

Nearly seven years after the triple reactor meltdown, this unique nuclear crisis is still underway. Of the many complex issues resulting from the disaster, one in particular may have become routine but is anything but normal: the vast amounts of nuclear waste, stored and being transported across Fukushima prefecture.

As a result of the Fukushima Daiichi accident, gases and particulates which vented into the atmosphere, led to radioactive fallout greater than 10,000 becquerels per square meter contaminating an estimated 8 percent, or 24,000 square kilometers, of the landmass of Japan. The highest concentrations (greater than 1 million becquerels per meter square) centered in an area more than than 400 square kilometers within Fukushima prefecture.

In the period 2013-14, the Japanese government set about a decontamination program with the objective of being able to lift evacuation orders in the Special Decontaminated Area (SDA) of Fukushima prefecture. Other areas of Fukushima and other prefectures where contamination was lower but significant were also subject to decontamination efforts in the so called Intensive Contamination Survey Area (ICSA).

Two areas of the SDA in particular were subject to concentrated efforts between 2014-2016, namely Iitate and Namie. A total of 24-28,000 people formally lived in these areas, with all evacuated in the days and months following the March 2011 disaster.

The decontamination program consisted of scraping, reverse tillage and removal of top soil from farmland, stripping and removal of soil from school yards, parks and gardens, trimming and cutting of contaminated trees and plants in a 20 meter area around peoples homes, and the same along a 10-15 meter strip either side of the roads, including into the nearby forests.

This program involved millions of work hours and tens of thousands workers (often Fukushima citizens displaced by the earthquake, tsunami and reactor meltdown), and often homeless and recruited off the streets of cities, and exploited for a wage of 70 dollars a day to work long hours in a radioactive environment. All this for a man-made nuclear disaster officially estimated at costing 21 trillion yen but with other estimates as high as 70 trillion yen.

As of March 2017, the decontamination program was officially declared complete and evacuation orders were lifted for the less contaminated areas of Namie and Iitate, so called area 2. The even higher radiation areas of Iitate and Namie, Area 3, and where no decontamination program has been applied, remain closed to habitation.

In terms of effectiveness, radiation levels in these decontaminated zones have been reduced in many areas but there are also multiple examples where levels remain significantly above the governments long range target levels. In addition to where decontamination has been only partially effective, the principle problem for Iitate and Namie is that the decontamination has created islands where levels have been reduced, but which are surrounded by land, and in particular, forested mountains, for which there is no possible decontamination. Forests make up more than 70% of these areas.

As a consequence, areas decontaminated are subject to recontamination through weathering processes and the natural water and lifecycle of trees and rivers. Given the half life of the principle radionuclide of concern – cesium-137 at 30 years – this will be an on-going source of significant recontamination for perhaps ten half lives – or 300 years.

So apart from the decontamination not covering the largest areas of significant contamination in the forested mountains of Fukushima, and in reality only a small fraction of the total landmass of contaminated areas, the program has generated almost unimaginable volumes of nuclear waste. According to the Japanese Government Ministry of Environment in its September 2017 report, a total of 7.5 million nuclear waste bags (equal to 8.4 million m³) from within the SDA was in storage across Fukushima.

A further 6 million m³ of waste is generated in the ICSA within Fukushima prefecture (but not including waste produced from the wider ICSA which stretches from Iwati prefecture in the north to Chiba in the south on the outskirts of Tokyo). In total nuclear waste generated from decontamination is stored at over 1000 Temporary Storage Sites (TSS) and elsewhere at 141,000 locations across Fukushima.

The Government projects a total of 30 million m³ of waste will be generated, of which 10 million is to be incinerated, generating 1 million cubic meters of highly contaminated ash waste. Options to use some of the less contaminated waste in construction of walls and roads is actively under consideration.

Government policy is for all of this waste to be deposited at two sites north of the Fukushima Daiichi plant at Okuma and Futaba – both of which remain closed to habitation at present but which are targeted for limited resettlement as early as 2021. Although the facilities are not completed yet, they are supposed to be in operation only for 30 years – after which the waste is to be deposited in a permanent site. The reality is there is no prospects of this waste being moved to another permanent site anywhere else in Japan.

As we conducted our radiation survey work across Fukushima in September and October 2017, it was impossible not to witness the vast scale of both the waste storage areas and the volume of nuclear transports that are now underway. Again the numbers are numbing.

In the space of one hour standing in a main street of Iitate village, six nuclear waste trucks passed us by. Not really surprising since in the year to October over 34,000 trucks moved nuclear waste across Fukushima to Okuma and Futaba. The target volume of waste to be moved to these sites in 2017 is 500,000 m³. And this is only the beginning. By 2020, the Government is planning for as much as 6.5 million m³ of nuclear waste to be transported to the Futaba and Okuma sites – a rough estimate would mean over one million nuclear transports in 2020.

On any measure this is insanity – and yet the thousands of citizens who formally lived in Namie and Iitate are expected and pressurized by the Japanese government to return to live amidst this nuclear disaster zone.

Perhaps one of the most shocking experience in our visit to Fukushima was to witness a vast incineration complex hidden deep in the woods of southern Iitate and a nearby vast storage area with tens of thousands of waste bags surrounded on all sides by thick forests. The tragic irony of a multi-billion dollar and ultimately failed policy of decontamination that has unnecessarily exposed thousands of poorly protected and desperate workers to radiation – but which leads to a vast nuclear dump surrounded by a radioactive forest which that can never be decontaminated.

There is no logic to this, unless you are a trucking and incineration business and of course the Japanese government, desperate to create the myth of recovery after Fukushima. On this evidence there is no ‘after’, only ‘forever’.

This new abnormal in Fukushima is a direct result of the triple reactor meltdown and a cynical government policy that prioritizes the unattainable fantasy of effective radioactive decontamination, while de-prioritising the safety, health and well being of the people of Fukushima.

The nuclear waste crisis underway in Fukushima is only one of the many reasons why the Japanese government was under scrutiny at the United Nations Human Rights Council (UNHRC) in Geneva last month. Recommendations were submitted to the United Nations by the governments of Austria, Mexico, Portugal and Germany at the calling on the Japanese government to take further measures to support the evacuees of Fukushima, in particular women and children.

The Government in Tokyo is to announce its decision on whether it accepts or rejects these recommendations at the United Nations in March 2018. Greenpeace, together with other human rights groups and civil society in Japan are calling on the government to accept that it has failed to defend the rights of its citizens and to agree to implement corrective measures immediately.
