Waterbug (OP) User ID: 1295673 ![]() 09/20/2011 09:31 PM Report Abusive Post Report Copyright Violation | Arnie does not have much confidance in the Mark I reactor containment design. They should all be decommissioned immediately. Quoting: Waterbug -here is an article concerning the Mark I from March 15th. March 15, 2011 Thirty-five years ago, Dale G. Bridenbaugh and two of his colleagues at General Electric resigned from their jobs after becoming increasingly convinced that the nuclear reactor design they were reviewing -- the Mark 1 -- was so flawed it could lead to a devastating accident. Questions persisted for decades about the ability of the Mark 1 to handle the immense pressures that would result if the reactor lost cooling power, and today that design is being put to the ultimate test in Japan. Five of the six reactors at the Fukushima Daiichi plant, which has been wracked since Friday's earthquake with explosions and radiation leaks, are Mark 1s. "The problems we identified in 1975 were that, in doing the design of the containment, they did not take into account the dynamic loads that could be experienced with a loss of coolant," Bridenbaugh told ABC News in an interview. "The impact loads the containment would receive by this very rapid release of energy could tear the containment apart and create an uncontrolled release." [link to abcnews.go.com] |

Waterbug (OP) User ID: 1295673 ![]() 09/21/2011 10:58 PM Report Abusive Post Report Copyright Violation | It is not an easy job. Filled with still-hot radioactive fuel, the reactors continue to require water, 550 tons daily, to stay below the boiling temperatures that sparked radiation-releasing hydrogen explosions during the crisis. Debris, some of it dangerously radioactive, remains on the site. Typhoon Roke passed over the site Wednesday, causing little damage but halting some radiation monitoring, according to TEPCO. A rapidly installed water-cooling system has kept the reactors stable since June. Spent nuclear fuel pools that burned during the crisis are now under control. A shutdown effort has begun that involves placing a plastic cover over one reactor's exploded building to contain radiation releases. TEPCO now says natural cooling of the melted reactor fuel should drop water temperatures below boiling before January. [link to www.usatoday.com] - mostly bovine excrement. |

Waterbug (OP) User ID: 1295673 ![]() 09/22/2011 11:08 AM Report Abusive Post Report Copyright Violation | First of all, I will give you a big thumbs up, waterbug, for keeping on, keeping on! keep it up. Quoting: Anonymous Coward 1548970 I just read that "they" are planning for a "possible" "massive" release, of radionuclides, in the very near future! This ^, is what I have been fearing, and waiting for. Everyones talked about the "china syndrome", but I have another, possibly greater worry. And that is that the corium is eventually going to slowly melt into the ground water. Causing not the massive unbelievably huge explosion that people are speculating, but instead a geyser of steam, gushing out endlessly, out of each, and eventually ALL six reactors! The rate of radiation pouring out every day has apparently been increasing ten fold. Which makes logical sense. They were talking becqerals, then gigabecqerals, then terabecqerals, and now I think its perabecqerals! Which is according to a very smart friend of mine, 1000 x 1000 more to the power of, or "in order of magnitude greater" Im not the smartest tool in the shed, and please exuse my dreadfull spelling. I asked my friend "what comes after perabecqerals??" and he said, "well, they will have to invent a new term" So together with the knowledge that the melted coriums radiation "grows" "climbs" "increases" etc for the first 250,000 years!! (the first "halflife" being the worst) and the fact that air measurements are doubling, quadrupling, etc every month, it wont be long at all I think before my feared geysers start erupting. People have spoken about the "fog" incidents on the webcams. I have seen this, when all at once an extremely dense "fog" suddenly covered the site. This to me, says that when the corium finally finds a suitable water source, well, hello old faithful. And when I read today about plans, and letting people in the outer exclusion zone know that soon there "may" be further massive releases, I shivered inside. My personal, albeit, naive, and ignorant, belief, is that the best thing that could happen actually is an enormous explosion!! I really think that is would be the best outcome at this stage. Simply because, the areas contaminated allready are going to remain so for thousands of years, so, it doesnt matter now if they were further contaminated. But the staedy non stop geyser like, steam eruptions from all six, would continue perhaps forever, with the rates of radiation INCREASING for 250,000 years, which says to me, the end of japan, then all "local" asian countries and finally the world at large!! I also cannot beleive that people around me are worried about elections and homeloans when this is happening. I am also worried about these so called "tents" they are planning on erecting. What on earth do they think that this will achieve? It is, to me, inconcievable that this "short term" "solution" is going to work at all. I think that they are "forgetting" about the suspended fuel pools. Which WILL eventually collapse, given what intense radiation does to metal. By covering the buildings with a "blanket" the radiation, "ever increasing" will destroy them. I dont know much in technical terms. But I can see a vision in my mind, or should I say nightmare? Cheynoble, and its "cover" is a disaster by itself. With temperatures close to 200 celcius, 25 years later, what on earth do they think will happen with fukushima. Condesation alone will cause the inside of the "tents" to become enormously "hot" given that they havnt been able to fully explore the buildings as it is due to massive readings........ There are other nuclear sites within cooee of fukushima, how long before they cant get near them? even with utterly suicidal workers? Good ol Arny Gunderson was saying yonks ago the worst of the releases was back in march, and that these so-called tents would help in containg releases....... I think hes wrong. At least on that score. (dont get me wrong, I think hes awesome) So finally to get to the point, recap etc the worst is yet to come, in my mind, and that worst is just around the corner. The reality of the situation is frightening and way to real for people to contemplate. We are watching what could well be the end of our civilisation, and even human life itself. I realise that sounds dramatic, even a little paranoid, but this situation is, in my mind, as bad as world war three, nuclear war etc. We are talking here about world wide nuclear fallout in every sense of the word. No, Im not going to slash my wrists, Im just here for the ride. peace................. So sorry I overlooked your post. (snip) Cheynoble, and its "cover" is a disaster by itself. With temperatures close to 200 celcius, 25 years later, what on earth do they think will happen with fukushima. Condesation alone will cause the inside of the "tents" to become enormously "hot" given that they havnt been able to fully explore the buildings as it is due to massive readings........ I feel the enclosures are partly to give the appearance of tidiness. The Japanese love order. They are offended at the sight of such devastation and chaos. Having a nice, neat cover over the reactors will allow them to be more effective in their assertions of control. Many will be lured into complacency. Out of sight/out of mind. The enclosures will also allow them to vent the buildings secretly during inclement weather and at night. At this point, after six months of daily investigation, I have reached a level of cynical acceptance that whatever will be, will be. The people we trusted to protect us from these types of disasters have failed. They have also declined to intervene in the situation. Good luck and live in peace. bug |

Anonymous Coward User ID: 1478654 ![]() 09/22/2011 07:45 PM Report Abusive Post Report Copyright Violation | Radioactive iodine spread south of nuclear plant A Japanese government survey shows that radioactive iodine emitted from the Fukushima Daiichi nuclear plant spread not only northwestward but also to the south of the plant. The science ministry sampled soil at 2,200 locations, mostly in Fukushima Prefecture, in June and July, and created a map indicating the extent of the radioactive contamination as of June 14th. The latest map shows that iodine 131 spread northwest of the plant, just like cesium 137 as indicated on an earlier map. But the substance was also confirmed south of the plant at relatively high levels. The researchers found that accumulation levels of iodine 131 were higher than those of cesium 137 in coastal areas south of the plant. [link to www3.nhk.or.jp] . |
Waterbug (OP) User ID: 1295673 ![]() 09/23/2011 08:31 PM Report Abusive Post Report Copyright Violation | Hydrogen detected in pipe at Fukushima No. 1 reactor According to Tokyo Electric Power Co., hydrogen of at least 10,000 parts per million was detected at two spots in a pipe passing through the containment vessel on the reactor building's first floor. This concentration was higher than TEPCO had anticipated. Although TEPCO is not certain how much hydrogen is still inside the vessel, the utility believes it is possible the concentration of the highly flammable gas is higher than had been assumed.

Argene User ID: 1435822 ![]() 09/24/2011 08:42 AM Report Abusive Post Report Copyright Violation | Nuclear experts rethink their future Quoting: Anonymous Coward 1478654 Japan's nuclear energy experts are discussing how complacency contributed to the accident at the country's Fukushima Daiichi power plant. They started a 4-day conference on Monday. It is their first major gathering since an earthquake and tsunami triggered a nuclear crisis. ... Complacency, hell! Look at the photos of the site. They forgot to build a sea wall to protect against a tsunami in a country where the run up from a tsunami has been frequently measured in excess of forty feet. Amazing stupidity! Then add to that the fact that they built their Emergency Diesel Generators in the basement of the turbine rooms where they would be flooded if a tsunami hit the plant that did not have a sea wall. All of their commercial power (that they needed to run the pumps that would be used in an emergency to cool the reactors and prevent a meltdown) came through one tower and that tower collapsed during the earthquake. The end result was that an electrical generating plant was without electricity while three nuclear reactors melted into the ground and are now polluting the whole damn earth so badly that an estimated ten million people will die from cancer in the northern hemisphere, CANCER THAT WAS CREATED BY THE FUKUSHIMA RADIATION. |

Waterbug (OP) User ID: 1295673 ![]() 09/24/2011 01:28 PM Report Abusive Post Report Copyright Violation | Radioactivity In Japan Rice Raises Worries Radioactive substances have already been discovered in beef, milk, spinach and tea leaves, leading to recalls and bans on shipments. But officials have been especially worried about rice, a staple that makes up a significant part of the Japanese diet. Japan grows most of the rice that it consumes. Preliminary tests on rice from paddies in the city of Nihonmatsu, about 35 miles from the Fukushima plant, showed the crops contained 500 becquerels per kilogram of radioactive cesium, prefectural officials said. Under recently adopted Japanese regulations, rice with up to 500 becquerels per kilogram of radioactive cesium is considered safe for consumption. (A becquerel is a frequently used measure of radiation.) [link to www.nytimes.com] |
