Fukushima wasn’t a “Japanese” nuclear accident—it was an accident that happened to occur in Japan. A blog on science, politics, and activism. Steam was regularly vented as part of the effort to relieve steam pressure within the reactor vessels, but this also led to an accumulation of hydrogen gas within the secondary buildings that house the reactor units. http://www.japansugoi.com/wordpress/cartoon-explaining-the-fukushima-nuclear-reactor-problem-to-kids/. Has there been any other reporting of the problems that were developing but seem to have disappeared as the radiation increases? Such is the growing international alarm about the nuclear crisis that France announced it was urging its citizens living in Tokyo to head to safer areas or to leave the country — apparently the most urgent instruction offered by foreign countries that so far had largely limited their advisories to simply avoid non-essential travel.” That said, you are correct that the known casualties are perhaps two workers who are missing, certainly less than the casualties we see from coal mining operations. Oh come now, this statement borders on the absurd. TEPCO said the first fire extinguished itself. .css-8h1dth-Link{font-family:ReithSans,Helvetica,Arial,freesans,sans-serif;font-weight:700;-webkit-text-decoration:none;text-decoration:none;color:#FFFFFF;}.css-8h1dth-Link:hover,.css-8h1dth-Link:focus{-webkit-text-decoration:underline;text-decoration:underline;}Read about our approach to external linking. Climate change is fueling wildfires. | Meu leitor BETA, Brave New Climate: Update on Reactor « Climate Denial Crock of the Week, Japanese Nuclear Power Plant Incident – UPDATE 2 « PA Pundits – International. Not a single human killed or injured by radiation is a success considering the circumstances.”. It’s tragic…. US election 2020: Who is ahead in the states still counting? That’s not the only logical conclusion, and we don’t know yet. o At 3:42PM on March 14, cooling of the reactor commenced, with TEPCO engineers working to achieve cold shutdown. Call for investments in public health and human security, not nuclear weapons. Demand the CDC continue collecting data on COVID-19 illness, hospitalizations, and deaths. The situation seems to be getting worse than what could reasonably have been expected on Sunday. Government officials said the traces found are connected with the nuclear plant. Kan also confirmed a fire burning at unit 4, which, according to all official sources, had never been a safety concern since the earthquake. It is such a disappointment every time we are briefly allowed to return home only to find out that we have been robbed again." Radiation has been released. Why isn’t it? For all the extensive detail it provides, what this report cannot fully convey - especially to a global audience - is the mindset that supported the negligence behind this disaster. I find it ironic that the power-plant over-heats because of lack of power. # BREAKING NEWS: Radiation levels at Fukushima plant rose after 10 a.m.: Edano (11:23) Democracy and science can be powerful partners for the public good—and both are under attack. A release of radiation is likely going to cause hysteria in a city of 9 million people 170 miles to the south (though to the credit of the Japanese people, their ability to stay relatively calm in these situation is admirable). For those interested, the reactor design pressure is 1250 psig and the drywell/torus design pressure is ~60 psig. After the first hydrogen explosion there is no longer a roof on the building, so there is little chance of any large buildup of hydrogen or further explosions at these units.

Fission isn’t “on” or “off” — it’s happening, and more will happen if the fuel gets too close together. What is it that saved Tokyo from a nuclear disaster? What can be done? Note that this is a blog, not a news website, and thus the following […], “Japan’s nuclear crisis intensified dramatically on Wednesday after the authorities announced that a second reactor unit at the stricken Fukushima Daiichi plant in northeastern Japan may have ruptured and appeared to be releasing radioactive steam. Note that the reactor of this unit is stable and was not operating at the time of the earthquake. Video, The man who feeds hundreds of parrots every day, Student ‘blown away’ by Mars footage. The unambiguous responsibility that operators should bear for a nuclear disaster was not specified. For a summary of the situation prior to today, read these posts: Japanese nuclear reactors and the 11 March 2011 earthquake, Fukushima Nuclear Accident – a simple and accurate explanation (with further updates at MIT here: http://mitnse.com/), Japan Nuclear Situation – 14 March updates, Further technical information on Fukushima reactors, TEPCO reactor by reactor status report at Fukushima. Thus, even though it was a natural event, an earthquake and tsunami that created this nightmare, we have no control over these things and so we see the nuclear power plants as similar in their ability to cause something of this scale, but something that we can control…and thus the focus on them and the worst case scenario. I’m just saying that before anyone can call this a disaster considereing the grand scope of things in that area now, there has to at least be an injury. As for not imagining a tsunami of those proportions, was this reviewed after Indonesia (etc) 2004? Worse, Japanese and U.S. regulators share a mindset that severe, supposedly “low probability” accidents are unlikely and not worth the cost and time to protect against. to me it seems more ignorant to NOT see those slight differences in culture, cause those – for sure – affect a lot. Click to access showfile.exe. (Comment by a resident of Okuma, from report appendices). Time will tell if this turns into the worst nuclear disaster in human history. See also:  Nuclear Overreactions: Modern life requires learning from disasters, not fleeing all risk. Not a single human killed or injured by radiation is a success considering the circumstances. With ponderous solemnity, he then made one outrageous and incorrect statement after another. While the veracity is hard to confirm, it seems very difficult to understand how they could not have been more vigilant on problems with the pool in unit 4. The Commission concludes that the residents' confusion over the evacuation stemmed from the regulators' negligence and failure over the years to implement adequate measures against a nuclear disaster, as well as a lack of action by previous governments and regulators focused on crisis management. # BREAKING NEWS: Containment vessels of No.1, No.3 reactors may be damaged: Edano (11:30) In contrast, the layfolk know that someone dies from cancer every minute and that millions die in car accidents per year; but they understand and know more about them and have a certain level of control. Repairs at unit 4 are now complete and Tepco said that gradual temperature reduction started at 3.42pm. Unfortunately, the NRC hasn’t learned Fukushima’s lessons—and U.S. nuclear power plants aren’t as safe as they could and should be. The underlying issue is the social structure that results in "regulatory capture," and the organisational, institutional, and legal framework that allows individuals to justify their own actions, hide them when inconvenient, and leave no records in order to avoid responsibility. The Commission concludes that the government and the regulators are not fully committed to protecting public health and safety; that they have not acted to protect the health of the residents and to restore their welfare. 2 reactor had also cracked. Prime minister Naoto Kan has requested that everyone withdraw from a 30 kilometer evacuation zone around the nuclear power plant and that people that stay within remain indoors. But let’s keep perspective. — I haven’t yet down the “recriticality” term — it has to be someone mangling a translation from the Japanese to English. Post was not sent - check your email addresses! This would have played havoc with the heat exchangers and other plumbing, setting the scene for the subsequent primary cooling circuit and spent fuel pool problems. It’s a very serious time for Japan. Could it not be that TEPCO was less than forthcoming with information? So we have damage that probably could have been avoided, and reporting of almost stunning inaccuracy and ignorance.Still, the odds are that no one will be hurt from radioactivity — a few workers from falling or in the hydrogen explosions, but tiny on the scale of the damage and killing around it. “The biggest problem is how to maintain the cooling and how to contain the fire at No. “Anyone know where the TEPCO original source for that is?” Its 619 MWe. Yes, we’ll have to wait and see, but so far only two deaths (reported missing) attributed to the tsunami, not radiation. “At the same time we have the nuclear reactor damage where not a single person has been killed or injured by radiation. He researches global change, ecology and energy. * Since they don’t know/understand what’s really going on and what the consequences are, it ups the fear factor.
