The Marketing-Speak Of The UNSCEAR Report On Fukushima

Friday much of the media reported a declaration that there were no health impacts from Fukushima. This wasn’t even close to what was actually said in UNSCEAR’s press statements while even more lies in the details and semantics of what was said. UNSCEAR’s statements say quite a bit more if you look at their qualifying statements and what they don’t say. From the UNSCEAR Press Release: UNSCEAR Statement: “Radiation exposure following the nuclear accident at Fukushima-Daiichi did not cause any immediate health effects. It is unlikely to be able to attribute any health effects in the future among the general public and the vast majority of workers,” What it means: Immediate is key, this same rather illogical statement was repeated ad nauseum as events unraveled in 2011. Immediate heath problems typically don’t happen unless … Read entire article »

UN Human Rights Report On Fukushima Finds Considerable Problems

The UN Human Rights Council report issued this month in an advanced edition spells out many issues that exist after the Fukushima Daiichi nuclear disaster. While most focus on the aftermath of the March 2011 nuclear events, some aspects apply to those impacted by just the quake and tsunami. This statement towards the end sums up the disconnect and problems currently going on: “The Special Rapporteur urges the government to adopt implementing measures to the Victims Protection Law and provide funding for relocation, housing, employment, education and other essential support needed by those who chose to evacuate, stay or return to any area where radiation exceeds 1mSv/year. These measures should include relief packages reflecting the cost of rebuilding lives.” Some notable aspects of the report are the breadth of issues it addresses. Many of the problems … Read entire article »

Belgian Reactors To Restart Despite High Risks

Belgian nuclear regulator FANC and Electrobel (plant operator) have announced the two Belgian reactors (Doel 3 & Tihange 2) found with thousands of cracks in the reactor vessels will be restarted. Both Bel V (a subsidiary of the Agency) and AIB Vinçotte (private company, agency inspection facilities) released reports questioning the safety of the units and serious concerns about the cracks. These two reports were barred from public view until a Green Party politician released copies on his website. Bel V urged additional testing including pressure testing of the reactor vessels. Electrobel claims the cracks are due to hydrogen in the steel fabricating process but Bel V points out that the cracks are only in the horizontal steel rings and not the connecting pieces, making the hydrogen explanation questionable. AIB Vincotte also raised … Read entire article »

TEPCO Holds “Black Box” Data About Fukushima Nuclear Disaster

In April of 2010 TEPCO signed a contract with high tech security company Magna BSP to provide a sophisticated video and trespass detection system  at the Fukushima Daiichi nuclear plant. This was the first installation of what was to be a series of similar installations at nuclear plants around Japan, coordinated between the government and nuclear operators. The system was installed at Fukushima Daiichi in 2010 Two TEPCO workers who were trained on the system weeks before the disaster were confirmed to have been among the Fukushima 50 who stayed at the plant during the worst of the disaster. To date TEPCO has not acknowledged the existence of the system or volunteered any of the video and data captured by the system to the public or the press. This data was never … Read entire article »

Sisyphus With A Paper Cup; TEPCO’s Enormous Water Problem

The contaminated water problems at Fukushima Daiichi have been plaguing the plant since day one. In recent months the problems have once again shown themselves to be too much for TEPCO to deal with while the plant continues to contaminate the environment. TEPCO stated that they were again, out of space only to find space after it became apparent the government would not allow them to dump contaminated water into the Pacific Ocean. This is something TEPCO has asked to do repeatedly since 2011 when they dumped contaminated water into the Pacific on top of what has been leaking. Contamination and contaminated water from the failed reactors is still making its way out of the plant a number of ways, all with long term major implications for the environment and public … Read entire article »

PEER REVIEW – Electrical

FUKUSHIMA DAIICHI POWER LOSS There was a back-up 66kV transmission line from the transmission network of Tohoku Electric Power Company, but the back-up line failed to feed Unit 1 via a metal-clad type circuit (M/C) of Unit 1 due to mismatched sockets. The EQ caused loss of off-site supply, because of loss of all seven grid connections to the site. The earthquake caused a lot of damage in the switchyards at the NPP At the nearby Shin-Fukushima substation to whichit is connected and to the circuits between them, including: o Collapse of one transmission tower, built on sloping ground, because of a landslide caused by the earthquake; o Damage to underground cables by subsidence; o Collapse of several high voltage circuit breakers; o Distortion, damage or collapse of several line switches (disconnectors); o Failure of suspension insulators; o Failure of an overhead earth wire (ground … Read entire article »

Corrosion At Fukushima Daiichi Explained

Corrosion At Fukushima Daiichi Explained by The fukuleaks.org/web Research Team A very critical factor in the aftermath of the nuclear meltdowns at Fukushima is stress and corrosion on metal parts of the reactors themselves and also the spent fuel and fuel pools. In this paper we look at corrosion factors and also the actual pipes in use at Daiichi for the ongoing watering effort. Corrosion The type of metal involved, mechanical loads and the type of fluid in contact with the metal will all impact the corrosion and destruction of pipes and metal. Mechanical loads can include movement of pipes and structures during the initial earthquake, ongoing aftershocks and also movement as equipment broke or shook during the meltdowns. Fluid includes the water that has been sent through the reactor pipe systems, reactor vessels and … Read entire article »

More On Unit 1′s Torus Situation

Along with the new information about the situation inside unit 1′s containment came some confusion online about the torus situation at unit 1. The Denki Shimbun reported recently that unit 1′s torus had “ a dose rate of about 10 Sv/h was observed in both the PCV and torus chamber.” This omits the significant findings in the torus of unit 1. TEPCO documents the very high readings found under water in the torus as “values of 108 to 109“. TEPCO found levels of 10 Sv/h in the air above the water in unit 1. The water surface was about 8 Sv/h, dropped into the 2-3 Sv/h range briefly then went into these incredibly high readings in the depths of the water inside the torus. TEPCO does cite instrument failure as “However, the dosimeter … Read entire article »

PEER REVIEW: Unit 4 soundness article

TEPCO released two reports in Japanese last week on order of NISA to explain the soundness of unit 4. Our rough machine translation is available here. The two extensive reports in Japanese were not made available in English. TEPCO has made an abbreviated version available today in English that omits or abbreviates a large amount of very critical information including the seismic statements and floor damage report details among others. TEPCO also released another document in Japanese late last week that has more data on the seismic determinations but was less publicized to the press and the public. In May 2012 we reviewed TEPCO’s available documents on unit 4′s stability and explained them in detail here, and a July 2012 follow up.

This is one section of a larger article on the thyroid issues for children in the Tohoku region of Japan after the Fukushima Daiichi nuclear disaster.   There are a couple of types of testing that can go on related to radiation exposure of the thyroid and later diagnostics looking for thyroid damage. Three efforts could be taken to test children for thyroid related radiation exposure. So far only two of them have, leaving those exposed without a critical test that could have verified with visual results the radiation in their thyroid soon after the disaster. 1. Checking for radiation in the thyroid using a hand held gamma counter. This is an insufficient method of checking for iodine 131 in the thyroid gland.

“Harmful Rumors” Law Revisited

Revisiting the “Harmful Rumors” law Many who were active in following the 3-11 disaster early on remember the actions taken by the Japanese government that raised major concerns about free speech and online privacy.

PEER REVIEW: Unit 2 New Scope Inspection – Data Sets

The second unit 2 scope project has been completed. TEPCO has released this PDF report on the project. Now in English here. Water was found 60cm above the concrete floor of the primary containment vessel. This indicates water is likely flowing out through the torus vent tubes. The elevation drawing shows where the 60cm of water would be located and it falls just at the lip of the vent tubes. It also shows that water is not staying in the torus as no water has built up and backed up into the main containment vessel. Water is leaving the torus. Water has to also be leaving the torus basement, aka: suppression chamber basement.

PEER NOTES: The Mangano Study Part II

The Nuclear Industry and Health AN UNEXPECTED MORTALITY INCREASE IN THE UNITED STATES FOLLOWS ARRIVAL OF THE RADIOACTIVE PLUME FROM FUKUSHIMA: IS THERE A CORRELATION? Joseph J. Mangano and Janette D. Sherman The multiple nuclear meltdowns at the Fukushima plants beginning on March 11, 2011, are releasing large amounts of airborne radioactivity that has spread throughout Japan and to other nations; thus, studies of contamination and health hazards are merited. In the United States, Fukushima fallout arrived just six days after the earthquake, tsunami, and meltdowns. Some samples of radioactivity in precipitation, air, water, and milk, taken by the U.S. government, showed levels hundreds of times above normal; however, the small number of samples prohibits any credible analysis of temporal trends and spatial comparisons. U.S. health officials report weekly deaths by age in 122 cities, about 25 to 35 percent of the national total. Deaths … Read entire article »

UK MOX Facility Becomes A Mega Money Pit, Japan Shares Losses

The UK government announced in August it would close the Sellafield MOX plant. The troubled plant to date has not produced any usable MOX fuel. Japan so far has been the only customer and the 1999 shipment to Takahama was returned after it was found to be defective. With TEPCO and CHUBU electric being the only customers lined up. TEPCO obviously isn’t in a position to attempt any further MOX programs. CHUBU owns Hamaoka nuclear power plant that has been shut down and a restart there is unlikely. Japan contributed a considerable amount of money to the plant in the UK, with the plant closure that money is lost. One of the major issues surrounding Sellafield is that the plutonium stockpile has been promoted as an asset. Without a reprocessing plant and … Read entire article »

Tomari Nuclear Plant To End Mox Program

Hokkaido Electric, owner of the Tomari Nuclear plant has announced they will end their pursuit to run MOX (Mixed Oxide plutonium fuel) in reactor #3. Hokkaido was caught up in the country-wide scandal where power companies were caught faking public support for MOX fuel programs. Our records show that no MOX fuel has been delivered to Tomari to date. There was a planned May 2011 shipment to Japan that may have been going to carry Tomari’s MOX assemblies. That shipment was cancelled after the Fukushima Daiichi disaster. Executives involved in the scandal received temporary pay cuts, none were fired for their involvement in the scandal.

Notes On Corium And Containment

My notes (Nancy’s) on the Reactor Safety Training Course (R-800) from the NRC http://pbadupws.nrc.gov/docs/ML0210/ML021080117.pdf The notes are an abbreviated gathering of parts that may be relateable to Fukushima from sections 3 and 4. Suppression Chamber: Steam can be sent from the RPV via a safety valve and piping into the suppression chamber (torus). If the pressure in the suppression chamber (wetwell/torus) is higher than that in the drywell vacuum breakers equalize the pressure. There is a cooling spray system for the drywell portion of containment and also cooling system in the suppression chamber that runs through a heat exchanger to cool the water in the suppression chamber. Mark 1 reactors also have a direct vent system to the outside in the suppression chamber to relieve pressure. (There were attempts to open these at Fukushima) Containment: Mark 1 containments were not specifically … Read entire article »

Thorium, Not The Nuclear Savior Claimed

As people have been discussing the issues surrounding the Fukushima Daiichi Disaster, the future of nuclear power comes up. Frequently someone will show up to the discussion to proclaim thorium will be the savior of the nuclear industry and all of the world’s power needs. The misinformation on thorium is highly promoted by the nuclear industry and various companies that want investment dollars for thorium reactors and fuel. This fairy tale being told about thorium is far from accurate and realistic. The problem becomes worse as uninformed people hear a brief propaganda piece on thorium and pass on that information without any research of their own. One myth is that thorium is safe. Thorium-232 has a half life of 14 billion years (billions, not millions). Thorium-232 is also highly radiotoxic, with the … Read entire article »

Fukushima Daiichi Intended To Increase MOX Use In Unit 3

Editors note: Documentation TEPCO #1 Documentation TEPCO #2 Preliminary Analysis of Tepco Documentation 3-2 “Tokyo Electric Power Co., Inc. Fukushima Daiichi Nuclear Power Station Unit 3 According to the results confirm the soundness of the new MOX fuel in the long-term storage” July 31, 2010 Nuclear and Industrial Safety Agency Introduction: Analysis of this document began under the premise that MOX fuel could in no possible terms be viable and intact after spending a period of 10-11 years in the spent fuel pool.  Documents show that 32 Mixed Oxide Fuel Assemblies were manufactured and sent to Fukushima-I in 1999.  These fuel assemblies were then stored in the Spent Fuel Pool of Reactor 3 pending local government approval.  This approval did not come until late summer of 2010, at which point arrangements were made and the fuel … Read entire article »
