“As of now, the levels we’re seeing are not harmful to humans. We’re basing this on Japanese studies following the Chernobyl incident in 1986 where levels of iodine-131 were four times higher than what we’ve detected in our rainwater so far,” Starosta said. “Studies of nuclear incidents and exposures are used to define radiation levels at which the increase in cancer risk is statistically significant. When compared to the information we have today, we have not reached levels of elevated risk.
Starosta predicts iodine-131 will be detected in B.C. up to three or four weeks after the Fukushima nuclear reactor stops releasing radioactivity into the atmosphere. The researchers will continue to monitor iodine-131 levels.

Those types of corrugated HDPE pipes are usually not used for pressurized gases, I've seen them used as drains and fiber conduit, but that's about it. Not sure what they are rated to hold, pressure wise.

After a 5.9-magnitude hit Mineral, Va. Tuesday afternoon, rocking the East Coast, concerns quickly turned to the safety of nuclear power plants. With the Fukushima power plant disaster in Japan fresh in people’s minds, nuclear power companies were quick to report on the conditions of their facilities.

"most likely relic hydrates, but there wouldn't be MH"
but thats the same as saying,,,,"its not regular gas, its unleaded".
who wrote it, ?

There are now more than 2,600 genetic diseases on record, any one of which may be caused by a radiation-induced mutation, and many of which we’re bound to see more of, because we are artificially increasing background levels of radiation.
Another important aspect to this whole nightmare of toxic exposure. It's not just this one thing, or that one thing, it's many illnesses we know of, and many we don't. Endocrine disruption showed us how little we know about illness and exposure to toxic substances. Radiation could be, on top of all we know, having wide ranging effects to the health and well being of humans that we aren't even aware of yet. And may never be aware of them cause industry and the rich have locked up the medical research field with money for cures (usually synthetic petrochemical pharmaceuticals they make more money from), and not research for prevention.

I have to take off for the day and wont have time to post the MH data, but I can say this. MH is ice under 164 times compression. It needs two distinct parameters to exist. These are temperature and pressure known as the stability zone. On either side of these parameters the MH comes out of it's frozen state and expands 164 times.
Much of the MH that was formed thousands and millions of years ago has now been buried deep enough so that the earth's inner warmth has heated the area to above the t/p stability zone, and these pockets are now just methane (or other nat gas, but mostly methane) under intense overpressures. These pockets are what cause many of the gas kicks when encountered in the drilling process.
Any MH that is now under land and not a part of permafrost has already been heated by the earth's inner temps and is in it's gaseous state. I call these pockets 'relic hydrates', but industry refuses to recognize their existence, and instead pretends that MH only exists where it could be formed today, and not a million years ago during an ice age when everything was much colder and the stablitiy zone was much wider.
So under Fuku there are most likely relic hydrates, but there wouldn't be MH.
The fourth of the Fukushima Daiichi reactors to be built. At the time of the earthquake unit 4 was shut down for extensive maintenance. The rod assemblies were removed from the core and stored in the spent fuel pool. Some of the extensive work to be done was the replacement of the reactor vessel shroud. Unit 4 lost AC power along with the other units at the plant. At 4:08am JST on March 14th, the spent fuel pool at unit 4 was 84 degrees celsius. At 6:20am JST on March 15th a part of a wall in the operation area of Unit 4 of Fukushima Daiichi was damaged. TEPCO provided no further details on this damage. At 9:38am JST on March 15th a fire broke out in the reactor building of unit 4, the fire was reported extinguished by 12:29pm JST. TEPCO has changed their story on unit 4 multiple times but eventually admitted to a very obvious explosion occurring at unit 4. No video of unit 4 exploding exists to date and it is assumed the explosion took place before dawn. One of TEPCO’s later admissions regarding unit 4 is that they think hydrogen leaked into unit 4 from unit 3 via the venting pipes and a faulty valve. No reason was given as to why unit 4 did not then ignite when unit 3 exploded.
The blast at unit 4 did extensive damage to the structural integrity of the building. TEPCO has admitted the blast ignited within both the lower floors and upper floors of the building. A concrete entrance garage can be seen to have the wall panels blown out. An inner staircase was identified as destroyed by TEPCO. There is extensive obvious structural damage. The spent fuel pool has been identified as leaking and unstable. Work cranes have been seen working around the building. The IAEA reported that on May 9th work began to structurally support the floor of the spent fuel pool at unit 4.
The days of seeing Japan in the news because of the earthquake and subsequent disaster are long over as attention has turned to more recent problems around the globe, but that doesn’t mean there aren’t big challenges remaining in the country. There’s still the case of the Fukushima nuclear power plant and four unstable reactors to deal with. Tokyo Electric Power Co. (TEPCO), which owns the Fukushima plant, is attempting to get things back to normal by using military robots provided by U.S. company iRobot.
Due to the lack of communications in the area of the plant, these robots are being operated by individuals who are put in danger every day close by the reactors as they go about their clean-up tasks. One of those operators decided to write a blog talking about his work, and it has proved very telling and informative about both the conditions at the plant and the robots themselves. Working conditions are less than perfect. Long hours, ignored warnings, and the link to the robots during crucial clean-up work being put in jeopardy due to stupid decisions are all touched upon. We also get to learn about the limitations and advantages of each robot in this rather unique situation.
However, it now seems as though the blog has disappeared just as it started getting popular, suggesting someone at TEPCO found it and took action.
Video footage of Tatsuhiko Kodama's impassioned speech before a Diet committee in July went viral online recently, showing the medical expert's shocking revelation that the Fukushima No. 1 nuclear plant spewed some 30 times more radioactive materials than the fallout from the Hiroshima atomic bombing.
Kodama, a professor of systems biology and medicine at the University of Tokyo, used clear-cut terms to get his message across. His ruthless criticism of the government's slow response has been viewed at least 1 million times.
"It means a significantly large amount of radioactive material was released compared with the atomic bomb," he told the Diet committee.
"What has the Diet been doing as 70,000 people are forced to evacuate and wander outside of their homes?"
Despite a hard-nosed image, the expert on radiology and cancer briefly showed a softer side while speaking to The Japan Times about his two grandchildren and their summer in the Tokyo heat.
"A lot of people ask me this, but Tokyo is safe from radiation now," Kodama, who heads the university's Radioisotope Center and the Research Center for Advanced Science and Technology, said Aug. 12.
"My two grandchildren swim outside in the pool, and there is no concern with the safety of food at this point."
But his expression became grave when discussing the 20-km no-go zone in Fukushima, explaining that decontamination of such areas will take not years but decades.
There are places he wouldn't let his grandchildren spend time outdoors freely, even in areas outside of the restricted zone.
Some 126 people have appeared before the independent panel investigating the causes of the Fukushima nuclear crisis, testifying for a total of almost 300 hours, but it will take more time and effort to identify the root reasons for the accident, panel leader Yotaro Hatamura said Tuesday. While Hatamura avoided giving much in the way of details about the hearings, such as specific questions asked and where the sessions have been held, he did say panel teams divided by topic have been holding hearings from various viewpoints, including tsunami measures at the Fukushima No. 1 plant, the evacuation procedures in the area surrounding the facility and how Tokyo Electric Power Co. handled the accident.
Hatamura said the committee, which was set up by the government in May, has held four sessions for a total of 19 hours with Masao Yoshida, director of the Fukushima No. 1 plant.
"I myself attended the director's sessions twice. I though he was answering all of our questions honestly," Hatamura, a professor emeritus at the University of Tokyo, told a news conference at the Cabinet Office.
The panel asked Yoshida to explain what happened to reactors 1 through 4 after the quake and his views on fuel rod damage as well as the cooling systems, ventilation and hydrogen explosions.
Hatamura acknowledged that there have been some findings that the media have not reported but said it is too early to determine precisely what went wrong.
Please read this Report here
Source: Massachusetts Institute of Technology (MIT) The Massachusetts Institute of Technology’s (MIT) Nuclear Science and Engineering faculty has created a report identifying and discussing technical issues arising from the accident at the Fukushima Daiichi nuclear complex in Japan. The report presents the reflections of members of the NSE faculty on the accident at Fukushima, and is offered as a contribution to the debate on the implications of the accident for the nuclear industry. The NSE purpose is twofold: to identify and discuss technical issues arising from the accident; and to begin a review of how the lessons learned can be used to improve the safety of current and future plants.
The information in the report is organized in six sections:
• Emergency Power following Beyond-Design-Basis External Events
• Emergency Response to Beyond-Design-Basis External Events
• Hydrogen Management
• Spent Fuel Pools
• Plant Siting and Site Layout F
For each area, the NSE presents key issues observed at Fukushima and corrective actions that should be evaluated for implementation in current and future plants.

I'm looking forward to reading this report in detail, however, first off it's dated May 2011! I would have thought August was way to early to 'review the technical lessons learned' given the accident is still ongoing, but May! Why are they just releasing it now? Why the delay? If it was written in May, a brief 3 months after the accident, why author a report like this when new revelations about lies and coverups are being admitted to and leaked every day? Then wait to release it? Shame on MIT! I will read it but seems like typical industry white-wash.edit on 23-8-2011 by Wertwog because: added something
