Threat from meltdown only minor: Ziggy Switkowski

March 14, 2011

The impact of any meltdown in Japanese nuclear reactors damaged by the recent earthquake will be small compared to the devastation caused by the quake itself and the subsequent tsunami, Australia’s best-known nuclear power expert says.

Ziggy Switkowski, who was chairman of the the Australian Nuclear Science and Technology Organisation (ANSTO) until a few months ago, says a significant build-up of radiation is unlikely.

“The contribution, if any, to this [disaster] from the nuclear fleet, I expect even under worst case scenarios is going to be small,” he told Fairfax Radio Network today.

“That’s not to deny that people are always concerned and justly concerned about the integrity of the nuclear reactor network,” Dr Switkowski said.

“The Japanese reactors are probably as good as you can find around the world, but this magnitude 9 earthquake may well have tested the limits of their design.”

Nonetheless, he said the nuclear situation in Japan was obviously very serious, ranking with the Three Mile Island disaster in the US in 1979 where a reactor was destroyed after the core melted.

“The Japanese reactors are not quite at that point. But there are obviously serious concerns about ensuring that the core of one of these reactors where the cooling isn’t working remains under control and does not melt and does not create radiation leaks.”

Describing this as the worst-case scenario, he said the melting would effectively destroy the core of the reactor.

“It could then over time just settle in and the reactor would be irreversibly damaged, or if there was an explosion – and it would be a chemical explosion, nuclear reactors can’t have atomic explosions – then there would be both physical damage and the release of radiation.”

The risk of an uncontrolled loss of containment of the core, releasing large amounts of radiation, was very, very small, and the radiation would probably not spread very far, he said.

Noting that people had been evacuated from a 20-kilometre exclusion zone around the reactors, he said, “I would think that the possibility that there would be significant build-up of radiation outside the zone would still remain low.”

PARTIAL QUOTE: “..The government has said that the plant’s three badly damaged reactors have been in a relatively stable state, called a cold shutdown, for months, and officials say that continues. But new tests suggest that the plant — which was ravaged last March when a powerful earthquake and tsunami hit the area — might not be as stable as the government or the operator of the plant, Tokyo Electric Power Company, or Tepco, had hoped. ….. The company announced this week that an examination of one reactor, No. 2, showed that the water level in an outer containment vessel was far lower than estimated, which could indicate that the already badly damaged uranium fuel might not be completely submerged and, therefore, is in danger of heating up.

Cooling water in that vessel, called the drywell, was just

two feet deep,
rather than the 33-foot level
estimated by Tepco officials
when the government declared the plant stable in December…

The high levels of radiation would complicate work to locate and remove the damaged fuel and decommission the plant’s six reactors — a process that is expected to take decades….

Throughout the nuclear crisis, both Tepco and the government were accused of playing down the dangers posed by the meltdowns at the plant. Subsequent disclosures that the event was indeed far more severe than they let on have badly damaged their credibility. ” end quotes.

Fukushima plant “great risk”: Head of nuclear accident probe panel

July 6, 2012
Kyodo News

The head of a Diet-appointed panel to investigate the Fukushima Daiichi nuclear power plant disaster said Friday that the crippled plant in northeastern Japan remains in a dangerous situation because of its fragile structure.

“Fukushima remains at a very high risk, not only because of the spent fuel issues, but also because of its fragile structure,” Kiyoshi Kurokawa, also professor emeritus at the University of Tokyo, told a press conference at the Foreign Correspondents’ Club of Japan, noting that another huge earthquake like the one last year may occur off the coast of northeastern Japan again.

The panel compiled a report Thursday that the Fukushima complex was “incapable of withstanding the earthquake and tsunami” that hit the plant on March 11, 2011. It also noted there is a possibility that the quake damaged safety equipment before the tsunami ravaged the plant and inundated power-supplying facilities needed to keep the nuclear reactors cool.

The Fukushima Daiichi nuclear power plant (DNPP) accident caused massive releases of radioactivity into the environment. The released highly volatile fission products, such as 129mTe, 131I, 134Cs, 136Cs and 137Cs were found to be widely distributed in Fukushima and its adjacent prefectures in eastern Japan. However, the release of non-volatile actinides, in particular, Pu isotopes remains uncertain almost one year after the accident. Here we report the isotopic evidence for the release of Pu into the atmosphere and deposition on the ground in northwest and south of the Fukushima DNPP in the 20–30 km zones. The high activity ratio of 241Pu/239+240Pu (> 100) from the Fukushima DNPP accident highlights the need for long-term 241Pu dose assessment, and the ingrowth of 241Am. The results are important for the estimation of reactor damage and have significant implication in the strategy of decontamination. end quote.

Video shows TEPCO’s hastiness in reporting cause of reactor explosion

August 08, 2012

By NAOYA KON/ Staff Writer

Tokyo Electric Power Co. announced, without verifying the cause, that a “hydrogen explosion” had occurred in its Fukushima No. 1 nuclear power plant on March 14, 2011, simply parroting what the government had reported.

The hasty announcement by TEPCO, the operator of the Fukushima plant, came following an explosion in the plant’s No. 3 reactor building, which occurred at 11:01 a.m. on March 14.

The sequence was among the 150 and a half hours of video conferencing recorded during the first days of the nuclear disaster, triggered by the Great East Japan Earthquake of March 11.

The footage in question was not on the 1.5-hour version of the video TEPCO released to the media, but was among the more than 150 hours of footage the utility allowed journalists to view on weekdays through Sept. 7, on condition no video or audio recording be made of any segments.

The footage, recorded around 11:30 a.m. on March 14, showed then TEPCO President Masataka Shimizu and Akio Takahashi, a senior official, sitting in a room in the company’s main office, discussing the wording of a news release, which would be similar to one made after a previous explosion in another reactor.

Two days before, on March 12, a hydrogen explosion had occurred in the plant’s No. 1 reactor building.

“In short, the only change we have made was replacing ‘No. 1 reactor’ with the ‘No. 3 reactor’?” Takahashi said in the footage. “We do not know whether it was a hydrogen explosion, but since the government–the Nuclear and Industrial Safety Agency–is saying it is a hydrogen explosion, we can just say so–a hydrogen explosion, can’t we?”

Takahashi urged that TEPCO parrot the government announcement, without trying to confirm the cause.

“On television a short while ago, NISA was saying it was a hydrogen explosion,” he said. “I guess we’d better keep pace.”

The footage also showed someone saying, “the prime minister’s office has also been using the term hydrogen explosion. Perhaps we should do the same,” but the person was not identifiable.

Shimizu approved Takahashi’s recommendation, saying, “All right. I agree. This is fine.”

Then followed two seconds of bleeped-out footage. Shimizu then said, “Speediness is the key.”

At a later news conference, a public relations official of the utility announced, “It was a hydrogen explosion.”

The cause of the explosion in the No. 3 reactor building has yet to be determined.

The government panel, led by University of Tokyo academic Yotaro Hatamura, said it was unable to make a ruling on claims from Mr Kan and others that TEPCO considered withdrawing staff and abandoning the stricken plant. Mr Kan said he ordered TEPCO to ditch plans for the evacuation of all staff.

Similarly, the report is silent on the role played by Fukushima Daiichi plant manager Masao Yoshida, who disregarded orders to wait and unilaterally injected seawater into the reactors.

Nearly 36pc of Fukushima children diagnosed with abnormal thyroid growths. Anxiety main focus of government.

This post consists of multiple articles in order to provide the response sequence of government which results in the shifting of focus from thyroid abnormalities to anxiety. ie government induced denial and blame shifting.
The need for civil protest in the face of deceptive leadership is obvious.

Japan Government Covers Up Children’s Radiation Doses, Again

http://www.simplyinfo.org/?p=6766

In a long list of bad actions by the Nuclear Emergency Response Headquarters, that has been in charge of radiation dose information, yet another cover up has come out.

The government announced the levels to be “zero” but the National Institute of Radiological Sciences (NIRS) says that is not the case.

“The government measured the hourly thyroid doses of 1,080 children under 16 years old in Fukushima Prefecture from March 24 to 30 last year, shortly after a disaster began to unfold at the Fukushima No. 1 nuclear power plant on March 11. Five months later, the government’s Nuclear Emergency Response Headquarters told the parents of 55 percent of the children that they had zero internal thyroid doses, which included doses below the detection limit of the testing equipment. A team of researchers led by Toshikazu Suzuki, a section head at the NIRS Research Center for Radiation Emergency Medicine, conducted an independent study of the same measurement data. The team estimated the lifetime thyroid doses of the 1,080 children at 12 millisieverts on average and 42 millisieverts at the maximum. The dose estimates were 30 millisieverts or more for four of the subjects. The children tested were from at least 10 municipalities, and the dose estimates tended to be higher for those from Iitate and Iwaki.”

Japan’s Fukushima Child Victims’ Law

Japan’s Fukushima Child Victims’ Law – Why Allow Chlidren to Live in Hot Zones?

Mainichi Daily News, Japan

Editorial: Diet should pass Fukushima child victims’ law and hold gov’t responsible

Lawmakers in both the ruling and opposition parties are in the final stages of composing a draft bill supporting victims of the Fukushima nuclear disaster, with an emphasis on providing support for children and pregnant women, who are said to be especially sensitive to radiation.

One of the pillars of the proposed legislation is the reduction or exemption of medical expenses for children and expecting mothers living in areas where radiation levels exceed a certain standard.

Many lives, especially those of Fukushima prefectural residents, have been turned upside down due to the nuclear disaster. A large number of people not under government orders to evacuate have done so anyway on their own volition, with many families being torn apart. The anguish of parents with young children, in particular, is immeasurable.

As local residents agonize over the lack of progress in decontamination efforts and any guarantees of health and food safety in the coming years, they face a basic question: will the national government continually enforce the measures and policies they seek?

“The Japanese reactors are probably as good as you can find around the world, but this magnitude 9 earthquake may well have tested the limits of their design.” The only thing he got right. And the ECCS vulnerablity to quakes has been known since the 1960s Ergen report by the AEC. Ziggy is one chilling dude.
