The Fukushima nuclear meltdown continues unabated — Helen Caldicott, Independent Australia

Helen Caldicott sums up the situation here:

” Recent reporting of a huge radiation measurement at Unit 2 in the Fukushima Daichi reactor complex does not signify that there is a peak in radiation in the reactor building.

All that it indicates is that, for the first time, the Japanese have been able to measure the intense radiation given off by the molten fuel, as each previous attempt has led to failure because the radiation is so intense the robotic parts were functionally destroyed.

The radiation measurement was 530 sieverts, or 53,000 rems (Roentgen Equivalent for Man). The dose at which half an exposed population would die is 250 to 500 rems, so this is a massive measurement. It is quite likely had the robot been able to penetrate deeper into the inner cavern containing the molten corium, the measurement would have been much greater.

These facts illustrate why it will be almost impossible to “decommission” units 1, 2 and 3 as no human could ever be exposed to such extreme radiation. This fact means that Fukushima Daichi will remain a diabolical blot upon Japan and the world for the rest of time, sitting as it does on active earthquake zones.

What the photos taken by the robot did reveal was that some of the structural supports of Unit 2 have been damaged. It is also true that all four buildings were structurally damaged by the original earthquake some five years ago and by the subsequent hydrogen explosions so, should there be an earthquake greater than seven on the Richter scale, it is very possible that one or more of these structures could collapse, leading to a massive release of radiation as the building fell on the molten core beneath. But units 1, 2 and 3 also contain cooling pools with very radioactive fuel rods — numbering 392 in Unit 1, 615 in Unit 2, and 566 in Unit 3; if an earthquake were to breach a pool, the gamma rays would be so intense that the site would have to be permanently evacuated. The fuel from Unit 4 and its cooling pool has been removed.

But there is more to fear.

The reactor complex was built adjacent to a mountain range and millions of gallons of water emanate from the mountains daily beneath the reactor complex, causing some of the earth below the reactor buildings to partially liquefy. As the water flows beneath the damaged reactors, it immerses the three molten cores and becomes extremely radioactive as it continues its journey into the adjacent Pacific Ocean.

Every day since the accident began, 300 to 400 tons of water has poured into the Pacific where numerous isotopes – including cesium 137, 134, strontium 90, tritium, plutonium, americium and up to 100 more – enter the ocean and bio-concentrate by orders of magnitude at each step of the food chain — algae, crustaceans, little fish, big fish then us.

Fish swim thousands of miles and tuna, salmon and other species found on the American west coast now contain some of these radioactive elements, which are tasteless, odourless and invisible. Entering the human body by ingestion they concentrate in various organs, irradiating adjacent cells for many years. The cancer cycle is initiated by a single mutation in a single regulatory gene in a single cell and the incubation time for cancer is any time from 2 to 90 years. And no cancer defines its origin.

We could be catching radioactive fish in Australia or the fish that are imported could contain radioactive isotopes, but unless they are consistently tested we will never know.

As well as the mountain water reaching the Pacific Ocean, since the accident, TEPCO has daily pumped over 300 tons of sea water into the damaged reactors to keep them cool. It becomes intensely radioactive and is pumped out again and stored in over 1,200 huge storage tanks scattered over the Daichi site. These tanks could not withstand a large earthquake and could rupture releasing their contents into the ocean.

But even if that does not happen, TEPCO is rapidly running out of storage space and is trying to convince the local fishermen that it would be okay to empty the tanks into the sea. The Bremsstrahlung radiation like x-rays given off by these tanks is quite high – measuring 10 milirems – presenting a danger to the workers. There are over 4,000 workers on site each day, many recruited by the Yakuza (the Japanese Mafia) and include men who are homeless, drug addicts and those who are mentally unstable.

There’s another problem. Because the molten cores are continuously generating hydrogen, which is explosive, TEPCO has been pumping nitrogen into the reactors to dilute the hydrogen dangers.

Vast areas of Japan are now contaminated, including some areas of Tokyo, which are so radioactive that roadside soil measuring 7,000 becquerels (bc) per kilo would qualify to be buried in a radioactive waste facility in the U.S..

As previously explained, these radioactive elements concentrate in the food chain. The Fukushima Prefecture has always been a food bowl for Japan and, although much of the rice, vegetables and fruit now grown here is radioactive, there is a big push to sell this food both in the Japanese market and overseas. Taiwan has banned the sale of Japanese food, but Australia and the U.S. have not.

Prime Minister Abe recently passed a law that any reporter who told the truth about the situation could be [jail]ed for ten years. In addition, doctors who tell their patients their disease could be radiation related will not be paid, so there is an immense cover-up in Japan as well as the global media.

The Prefectural Oversite Committee for Fukushima Health is only looking at thyroid cancer among the population and by June 2016, 172 people who were under the age of 18 at the time of the accident have developed, or have suspected, thyroid cancer; the normal incidence in this population is 1 to 2 per million.

However, other cancers and leukemia that are caused by radiation are not being routinely documented, nor are congenital malformations, which were, and are, still rife among the exposed Chernobyl population.

Bottom line, these reactors will never be cleaned up nor decommissioned because such a task is not humanly possible. Hence, they will continue to pour water into the Pacific for the rest of time and threaten Japan and the northern hemisphere with massive releases of radiation should there be another large earthquake. ”

For 6,000, the daily bus ride takes them to Fukushima plant — The Asahi Shimbun

” NARAHA, Fukushima Prefecture–Despite the predawn hour, few people are sleeping on a bus that steadily makes its way north on National Route 6.

Some passengers are planning for the work ahead. One is looking forward to chatting with his colleagues. And a few wonder if today will be the day when their annual radiation doses reach the safety limit.

Every day, buses like this take 6,000 workers to the Fukushima No. 1 nuclear power plant. And every day, the same buses take the exhausted and mostly sleeping workers back to their base at the Japan Football Village (J-Village) in Naraha.

Although the Fukushima plant is still decades away from being decommissioned, without this daily routine of the workers who toil amid an invisible danger, the situation at the site would be much more difficult.

407 Daily Bus Rides

One of them, the 49-year-old leader of a group of metal workers from Iwaki, Fukushima Prefecture, has been working at nuclear plants, including the Kashiwazaki-Kariwa power station in Niigata Prefecture, for nearly 20 years.

He was at the Fukushima No. 1 nuclear plant when the Great East Japan Earthquake and tsunami triggered the triple meltdown there in March 2011.

“Nobody can get close to the area where the melted nuclear fuel remains due to high radiation doses,” the man said. “Even if we could approach the area, we would have no way out if something happens. The situation is harsh.”

Those metal workers install tanks for the contaminated water that keeps accumulating at the plant.

Although there are plenty of empty seats, the young workers sit in front and the older workers take the back seats.

Thousands of workers are staying at temporary dormitories set up in J-Village, a soccer training complex.

Tokyo Electric Power Company Holdings Inc., operator of the nuclear plant, hired a local bus company to transport the workers to the plant because securing parking areas near the site has been difficult since the 2011 disaster.

The company provides 407 services a day to and from the plant. Each trip takes about 30 minutes.

The first shuttle bus departs from J-Village at 3:30 a.m., while the last bus leaves the Fukushima plant at 9:45 p.m.

In mid-November amid torrential rain, one bus picked up a man taking shelter under the eaves of a bus stop.

He said he is in charge of managing data related to radiation doses of fittings and other equipment at the plant.

“We have many different types of work here,” the man proudly said.

Also on the way to the nuclear plant, a 53-year-old employee of a security company was thinking about personnel distribution.

Like other workers there, security guards must be replaced when their annual radiation doses reach a certain level set by the government.

He said he has difficulties making ends meet with a limited number of guards who have knowledge about radiation.

Suddenly, the man’s cellphone rings, and the caller orders the deployment of additional security guards to the plant.

A 52-year-old TEPCO employee was on the way to the nearby Fukushima No. 2 nuclear power plant to provide a safety training program for workers, many of whom are victims of the triple disaster.

“I want to convey to workers how precious their lives are and how important safety is in a way that doesn’t make me sound hypocritical,” the employee said.

The triple meltdown has been called a “man-made disaster” caused by the failure of both TEPCO’s management and the government’s regulatory authorities.

The TEPCO employee will use props, such as a ladder, and pretend to be a worker to explain dangerous cases at the No. 1 plant.

Premium Seats

On the trip back to J-Village, a different atmosphere exists on the bus.

Although dazzling sunlight shines through the windows and stunning views of the ocean are available, most of the workers are fast asleep in their wrinkled uniforms.

“Few people stay awake. I don’t even switch on the radio. They must be tired after their work,” said Nobuyuki Kimura, 52, who has driven the shuttle bus for one-and-a-half years.

In Kimura’s bus that departed the plant at 2:30 p.m., all 50 seats and some of the auxiliary seats were filled. The few passengers who stayed awake remained quiet.

By early evening, fewer workers boarded the bus at the plant.

Window seats at the back of the bus are desirable on all rides because they have an enough room for the seats to recline, allowing passengers to cross their legs.

A 21-year-old worker from Iwaki went for a window seat at the back after standing at the front of a line waiting for the bus.

“I can relax sitting here. This is the premium seat,” said the man who collects waste materials, such as boots and socks, at the site.

Although he works in protective gear in an area with high radiation levels, he said he has never thought about quitting his job.

He said he became fed up with school as a junior high school student, and did not bother going to senior high school.

At the age of 18, he joined his current company, and his first assignment was at the Fukushima No. 1 plant.

“I became acquaintances with more and more people. It’s fun to speak with people at work,” he said.

Through his work at the nuclear plant, his weight has dropped from 115 kilograms to 93 kg.

Thirty to 40 years are needed to decommission the Fukushima No. 1 plant, according to the mid- and-long-term roadmap compiled by the government and TEPCO.

To reduce the groundwater flowing into the buildings housing the No. 1 to No. 4 reactors, TEPCO installed coolant pipes this year to create an underground frozen soil wall to divert the water into the ocean.

TEPCO announced in October that the ice wall on the sea side was nearly frozen, but groundwater is believed to be seeping through it.

The utility plans to start removing spent fuel from the No. 3 reactor building in fiscal 2017. It also has plans to begin the daunting task of removing the melted fuel from the No. 1 to No. 3 reactor containment vessels in 2021.

However, extremely high radiation levels have prevented workers from approaching and understanding the condition of the melted fuel. The removal method has yet to be decided.

The estimated cost of work for decommissioning and dealing with the contaminated water has ballooned to 8 trillion yen ($68.1 billion). ”

First thyroid cancer case in Japan recognized as Fukushima-related & compensated by govt — RT

” A man who worked at the Fukushima nuclear power plant in Japan during the disastrous 2011 meltdown has had his thyroid cancer recognized as work-related. The case prompted the government to finally determine its position on post-disaster compensation.

The unnamed man, said to be in his 40s, worked at several nuclear power plants between 1992 and 2012 as an employee of Tokyo Electric Power Company Holdings Inc. He was present at the Fukushima Daiichi nuclear power plant during the March 11, 2011 meltdown. Three years after the disaster, he was diagnosed with thyroid gland cancer, which the Japanese Ministry of Health, Labor and Welfare confirmed on Friday as stemming from exposure to radiation.

The man’s body radiation exposure was totaled at 150 millisieverts, almost 140 of which were a result of the accident. Although this is not the first time that health authorities have linked cancer to radiation exposure for workers at the Fukushima plant, it is the first time a patient with thyroid cancer has won the right to work-related compensation.

There have been two cases previously, both of them involving leukemia.

The recent case prompted Japan’s health and labor ministry to release for the first time its overall position on dealing with compensation issues for workers who were at the Fukushima plant at the time and after the accident. Workers who had been exposed to over 100 millisieverts and developed cancer five years or more after exposure were entitled to compensation, the ministry ruled this week. The dose level was not a strict standard but rather a yardstick, the officials added.

As of March, 174 people who worked at the plant had been exposed to over 100 millisieverts worth of radiation, according to a joint study by the UN and the Tokyo Electric Power Company. There is also an estimate that more than 2,000 workers have radiation doses exceeding 100 millisieverts just in their thyroid gland, Japanese newspaper the Asahi Shimbun reported.

The 2011 accident at the Fukushima nuclear power plant was the worst of its kind since the infamous 1986 catastrophe in Chernobyl, Ukraine. After the Tohoku earthquake in eastern Japan and the subsequent tsunami, the cooling system of one of the reactors stopped working, causing a meltdown. Nearly half a million people were evacuated and a 20-kilometer exclusion zone was set up. ”

Cancer patient compensated for Fukushima work to sue Tepco — The Asahi Shimbun

” A 42-year-old man diagnosed with leukemia after working at the crippled Fukushima No. 1 nuclear plant plans to sue Tokyo Electric Power Co., saying the utility failed to take adequate precautions against radiation exposure.

He will also sue Kyushu Electric Power Co., operator of the Genkai nuclear plant in Saga Prefecture where he had also worked, in the lawsuit expected to be filed at the Tokyo District Court on Nov. 22.

The man, who is from Kita-Kyushu in Fukuoka Prefecture, will demand about 59 million yen ($541,000) in total compensation from the two utilities.

“TEPCO and Kyushu Electric, as the managers of the facilities, are responsible for the health of workers there, but they failed to take adequate measures to protect them from radiation exposure,” said one of the lawyers representing him.

“The man was forced to undergo unnecessary radiation exposure because of the utilities’ slipshod on-site radiation management, and as a result had to face danger to his life and fear of death,” the lawyer said.

The lawyers group said the man has a strong case, citing a ruling by labor authorities in October 2015 that recognized a correlation between his leukemia and his work in response to the 2011 Fukushima nuclear disaster.

It was the first time cancer was ruled work-related among people who developed the disease after working at the stricken Fukushima No. 1 nuclear plant.

The planned lawsuit will be the first legal action against TEPCO brought by an individual whose work-related compensation claim has already been granted.

Between October 2011 and December 2013, the man worked at the Fukushima No. 1 nuclear plant to set up a cover on the damaged No. 4 reactor building and perform other tasks.

The man also did regular maintenance jobs at the Genkai plant.

His accumulative radiation exposure at the two plants came to about 20 millisieverts.

He was diagnosed with acute myelocytic leukemia in January 2014. ”

Untrained staff did radioactive cleanup work in Fukushima — The Asahi Shimbun

” NIHONMATSU, Fukushima Prefecture–A company has admitted to not giving the required special training to workers before dispatching them to carry out decontamination work in radiation-hit Fukushima city.

A subcontractor called “Zerutech Tohoku” issued at least 100 bogus certificates to its workers showing they had completed the training, when, in fact, they had done nothing, according to the Fukushima Labor Standards Inspection Office.

The office had warned the subcontractor, which is based in Nihonmatsu and decontaminates parts of nearby Fukushima city, which was affected by the 2011 nuclear disaster, that it should give special training to workers to prepare them for the task.

The Ministry of Health, Labor and Welfare requires decontamination operators be given at least 5.5 hours of special training to each individual in accordance with the Industrial Safety and Health Law.

The training includes a lecture on potential health hazards and how to operate decontamination equipment as their job involves handling soil polluted by radioactive materials.

The 52-year-old representative of the company admitted wrongdoing in an interview with The Asahi Shimbun.s

“We had to hire a large number of workers over a short period of time since we received a contract involving a vast swath of land,” he said of the false certificates, of which between 100 and 150 have been discovered.

In addition, the company, a fourth-tier subcontractor, issued seven other kinds of certificates needed to operate an aerial vehicle or chain saw, which were required to land the cleanup contract.

For issuing false certificates, offenders could be imprisoned for up to six months or fined 500,000 yen ($4,800).

But the law has been criticized for having numerous loopholes.

One is that there is no test of workers’ knowledge after they have received the training.

The operators are also not required to register the certificates with municipal authorities.

And it is not specified what qualifications are required for the person who conducts the training.

The Labor Standards office, a regional arm of the health ministry, has been inspecting the company for breaches of the law and regulations on decontamination work since Oct. 19.

The Zerutech Tohoku representative founded the company in March last year. ”
