Nuked Fukushima Plant: New High Radiation Areas Found

More Radiation Hotspots Found at Fukushima NPP

The operator of Japan’s nuked Fukushima plant has found two new radiation hotspots near storage tanks holding highly irradiated water, raising fear of new leaks as the extent of the disaster widens.

The news follows a press release earlier this week in which Tokyo Electric Power Co (TEPCO), a name now synonymous with incompetence, treachery and cowardice, admitted contaminated water with dangerously high levels of radiation was leaking from one of its purpose-built storage tanks.

The first of the two highly irradiated areas was found near the tank No. 4 in the group B in the H3 area, with a reading of 100mSv/h, and the second was near storage tank No. 10 in the group A in the H3 area, where the reading was 70mSv/h.

The company’s latest press release is posted below.

Press Release (Aug 22,2013) – Water Leak at a Tank in the H4 area in Fukushima Daiichi Nuclear Power Station (Follow-up Information 10)

This is follow-up information on the “water leak at a tank in the H4 area in Fukushima Daiichi Nuclear Power Station” found on August 19.

From around 11:00 AM to around 3:00 PM, we conducted full inspections (appearance inspections and dose measurement) on the flanged tanks in the other areas, which are of the same type as the tank from which water has leaked.

Neither leak nor puddle was found by the appearance inspections on the tanks and the drain valves. However, 2 locations locally showing high dose rates were found around the H3 area tanks.

The surfaces of these locations were dry, and we confirmed that water flowed out neither into the inside of the dike nor into the outside of the dike. We also confirmed that the water levels of these tanks remain unchanged after receiving water.

[High dose rate locations, the surface dose equivalent rates at these locations (γ and β rays (70μm dose equivalent rate)), and tank water levels]
” Near the bottom flange of the tank No. 4 in the group B in the H3 area: 100mSv/h and approx. 97% of the full water level
” Near the bottom flange of the tank No. 10 in the group A in the H3 area: 70mSv/h and approx. 95% of the full water level

No locations around the other tanks and drain valves showed high dose rates.

What is a lethal dose of radiation from a single Exposure?

Studies of the 1945 atomic bombing at Hiroshima and Nagasaki show that 100 percent of victims whose bodies were exposed to 600,000 millirems (6,000 mSv) died from radiation. About 50 percent of victims who received  450,000 millirems (4,500 mSv) of radiation also died.

(Note: Rem is a unit of ionizing radiation equal to the amount that produces the same damage to humans as one roentgen of high-voltage x-rays.  Source: MIT)

Chernobyl Disaster: Ukraine Marks 27th Anniversary

Radioactive cloud from Chernobyl explosion traveled half way around the world

The explosion at Chernobyl nuclear power plant 27 years ago has so far claimed at least a million lives, and counting. The core meltdown, which occurred on Saturday, April 26, 1986 at reactor No. 4 of the V.I. Lenin Nuclear Power Station, as it was then called, left entire regions in three countries—Ukraine, Russia and Belarus—unlivable.

The radionuclide levels still exceed the normal background in 60 Ukrainian towns and villages.

Ukraine’s Chernobyl nuclear power plant underwent a core meltdown [center] in 1986 with disastrous consequences. The radionuclide levels still exceed the normal background in 60 Ukrainian towns and villages. This image was taken by authorities in the former Soviet Union.

Ongoing Health Issues

“The nation’s health is deteriorating,” Mykhailo Kurik, director of the Ukrainian Institute of Ecology, told Xinhua, asserting that the damage to nature and environment was severe and long-lasting.

“Just after the accident, a huge quantity of radionuclides, including the burning particles, which are extremely dangerous for the environment, were released. These isotopes have very long half-lives, so Ukraine will feel the devastating effects of the catastrophe for decades,” Kurik said.

Radioactive emissions from Chernobyl explosion were more than 100 times higher than the combined contamination caused by the atomic bombs dropped on Japan’s Hiroshima and Nagasaki, experts have said.

Remembering Chernobyl Victims

The sarcophagus covering the damaged fourth reactor at the Chernobyl nuclear power plant is seen behind a building decorated with a graffiti in the abandoned city of Prypiat April 4, 2011. Belarus, Ukraine and Russia will mark the 25th anniversary of the nuclear reactor explosion in Chernobyl, the place where the world’s worst civil nuclear accident took place, on April 26. Engineers are still struggling to regain control of damaged reactors at the Fuskushima plant after last month’s earthquake and tsunami, in the worst nuclear crisis since Chernobyl in 1986, with the government urging the operator of the plant to act faster to stop radiation spreading.

Never Ending Nightmare at

“In mid-February, a 600-square-meter section of the roof at the Chernobyl site collapsed, sparking fears of another disaster. The collapse occurred 70 meters above the sarcophagus that contains the radiation from the damaged No. 4 reactor.” Said a report.

Experts estimate that 190 tons of reactor fuel remain under the existing sarcophagus that covers the disaster stricken power plant.

Birth defects and cancer were the norm for many years following the Chernobyl disaster.  By the time  residents of Pripyat, a town located near the plant, were ordered to evacuate, about two days after the Chernobyl core meltdown had occurred, many had already been exposed to varying doses of radiation poisoning.

1 Million Killed in Chernobyl Disaster

“A report by Alexey Yablokov, Vassily Nesterenko and Alexey Nesterenko which appeared in the Annals of the New York Academy of Science showed that by 2004, there were 985,000 additional deaths worldwide caused by the nuclear disaster, including 212,000 of them within Western Russia, Belarus and Ukraine.”

Chernobyl fallout covers the entire Northern Hemisphere

Consequences of the Catastrophe. Authors  Alexey Yablokov (Center for Russian Environmental Policy in Moscow), Vassily Nesterenko and Alexey Nesterenko ( Institute of Radiation Safety, Minsk, Belarus) studies about 5,000 reports and scientific  papers mostly published in Slavic languages and compiled their finding in the  book “Chernobyl: Consequences of the Catastrophe for People and the Environment,” which was published last year on the 24th anniversary of the Chernobyl reactor core meltdown.

“For the past 23 years, it has been clear that there is a danger greater than nuclear weapons concealed within nuclear power. Emissions from this one reactor exceeded a hundred-fold the radioactive contamination of the bombs dropped on Hiroshima and Nagasaki.” They wrote.

“No citizen of any country can be assured that he or she can be protected from radioactive contamination. One nuclear reactor can pollute half the globe,” the authors said. “Chernobyl fallout covers the entire Northern Hemisphere.”

According to the book, a total of about 830,000 people, referred to as the “liquidators,” were responsible for various emergency works at the Chernobyl site including fire extinguishing, decontamination and cleanup.

The authors say between 112,000 and 125,000 of the  liquidators had died by 2005.  The authors also estimate that between 1986 and 2004 some 985,000 people died as a result of Chernobyl fallout {2011 estimates are well over a million deaths.]

“Official discussions from the International Atomic Energy Agency and associated United Nations’ agencies (e.g. the Chernobyl Forum reports) have largely downplayed or ignored many of the findings reported in the Eastern European scientific literature and consequently have erred by not including these assessments.” The authors said last year.

Chernobyl and Other Nuclear Stats

• More than 95% of the radioactive material (180 metric tons with a radioactivity of about 18 million curies) still remains inside the Chernobyl reactor.
• The  core meltdown at Chernobyl was said to have released radiation estimated at 50 million curies. Committee on the Safety of Nuclear Installations said in 1995 that the meltdown had released about 140 million curies. [Researchers Alexey Yablokov, Vassily Nesterenko and Alexey Nesterenko say the radiation released from Chernobyl may have been up to 10 billion curies. In comparison, the Hiroshima bomb released about 3 million curies.]
• Immediately after the accident, 237 people suffered from acute radiation sickness, and 31 died within the first 90 days of the disaster.
• About 135,000 people were evacuated from the area surrounding the plant, including 50,000 from the town of Pripyat.
• The Academy’s  estimate for the number of casualties  are more than 90,000 deaths and more than a quarter of a million cancer cases.
• The Ukrainian National Commission for Radiation Protection calculates the number of radiation casualties at half a million  deaths so far.
• In a book published by the New York Academy of Sciences last year on the 24th anniversary of the reactor core meltdown, the researchers maintain that about one million people have died from exposure to radiation released by the Chernobyl reactor so far [as of 2010.]
• “In the former Soviet Union at least 9 million people have been effected by the accident; 2.5 million in Belarus; 3.5 million in Ukraine; and 3 million in Russia. In total over 160 000 Km2 are contaminated in the three republics.” source
• Some 441 commercial nuclear power reactors are  operating in 31 countries ( total capacity of 376 gigawatts) each of which is potentially as lethal as Chernobyl, if not worse. [This item, updated here, was written before the Fukushima nuclear disaster began unfolding.]
• An estimated 56 countries operate more than 250 research reactors.
• At least 220 nuclear reactors power military ships and submarines.

Legacy: More than 4,000 cases of thyroid cancer were diagnosed among children and adolescents between 1992 to 2002 in Belarus, Russia and Ukraine. Victims under 14 years were most severely affected by the elevated concentrations of radioiodine found in milk.

• Incidents of skin lesions, respiratory ailments, infertility and birth defects were readily found among the more than five million people who inhabit the affected areas of Belarus, Russia, and Ukraine for many years following the accident.

The Poisoned land. Up to 5 million people continue to live on radioactive contaminated land. About 85% of the children who live in contaminated areas of Belarus today are ill, a near 6-fold increase compared to the time before the explosion (15%), according to The Belarusian National Academy of Sciences.

Fukushima NPP

Fukushima NPP is said to contain about 4,277 tons of nuclear fuel, about 24 times as much as Chernobyl (~ 180 tons).

“The Fukushima Dai-ichi site has a considerable number of fuel rods on hand, according to information provided Thursday by Toyko Electric Power Co., which owns the atomic complex: There are 3,400 tons of fuel in seven spent fuel pools within the six-reactor plant, including one joint pool storing very old fuel from units 3 and 4. There are 877 tons in five of the reactor cores. Officials have said that the fuel in Unit 4′s reactor vessel was transferred to its spent fuel pool when the unit was temporarily shut in November.” AP reported.

On April 12, Japanese authorities raised the measure of severity of the Fukushima NPP disaster to the maximum level of 7 on INES. (See below for details.)

The International Nuclear and Radiological Event Scale (INES)

The INES, a logarithmic scale, which was introduced in 1990 by the IAEA to enable prompt communication, classifies the intensity of nuclear incidents as follows:

7 – Major Accident [Chernobyl disaster, criticality accident, April 1986]

6 – Serious Accident [e.g., Kyshtym incident, Mayak, former Soviet Union, steam explosion released up to 80 tons of highly radioactive material into the atmosphere, September 1957. ]

5 – Accident With Wider Consequences [e.g., Three Mile Island accident  Pen State, U.S., partial meltdown release radioactive gases  into the environment, March 1979.]

4 – Accident With Local Consequences [e.g., Sellafield, UK, at least 5 incidents reported between 1955 to 1979]

3 – Serious Incident [e.g., Vandellos NPP, Spain, fire destroyed control systems; the reactor was shut down, July1989]

2 – Incident [e.g., Forsmark NPP, Sweden, a backup generator failed, July 2006]

1 – Anomaly [e.g., TNPC, France, 1,600 gallons of water containing 75 kilograms (170 lb) of uranium leaked into the environment,  July 2008]

0 – Deviation (No Safety Significance) — [e.g., Atucha, Argentina – Reactor shutdown caused by tritium increase in reactor encasement, December 2006.]
