Tweek Posted March 13, 2011 Share Posted March 13, 2011 The reactor core has been exposed to the air, hence the reason the building exploded, add in that particals of radation were found outside the plant that could only come from an exposed core, I don't think that's quite true. According to most experts it is only likely that the external cooling system exploded (cooling water split into O2 and H and the H exploded), and the reactor core is still intact and not exposed. But I take the point that there is a lot of misinformation flying about. Link to comment Share on other sites More sharing options...

Tweek Posted March 13, 2011 Share Posted March 13, 2011 I can never understand the mentality of building homes and businesses, let alone nuclear power plants, in areas prone to Tsunamis (major history of them in many areas of Japan). In the UK now, 1 in 6 houses has been built on a floodplain, yet with plenty of non-floodplain land available. Why is it human beings think they can control or outwit everything? Nature always claims things back eventually. Link to comment Share on other sites More sharing options...
gazza Posted March 13, 2011 Share Posted March 13, 2011 Onagawa nuclear plant has increased radation lvls to 700 times there normal but they still say the readings are low and no problem to worry about!!!!!, State of emergency declared at that plant, heres the rub, they say the plant is fine and no problems and that the readings are from when the fukushima plant exploded, but they said that radation never got out!!! the fact that its well over 100km away and not vary far from tokyo, a lot of information not being released, And japan has a bad tract reacord of saying the truth about these things as well, with that company that runs the plant having at least 26 times been caught giving false data, Every expert says the same thing that the plants are in a lot of trouble and the jap are not saying the whole truth. reactor no3 has lost its cooling thay are now pumping sea water into this but have no way of knowing what lvl the water is at because the gauges are broken so god knows this is the one with the MOX fuel, no2 is getting sea water pumped in as well, 2nd plant in the fukushima area has problems as well, 2 reactors there are getting vented as well, not looking good. * MOX is mixture of plutonium oxide and uranium oxide. 3rd plant has just lost its cooling pumps!!!

Nature always claims things back eventually. Because that's where they live. If Japan decided to up sticks and relocate to the UK, the mail readers would have a field day. I think the international response, in terms of technical help, is beyond par. Especially New Zealand. Their team must be traumatised enough, and already they are in Japan helping. Even China, who had an earthquake last week, are sending teams of people to help. Link to comment Share on other sites More sharing options...

In Japans case they built in the fertile flat lands below the mountains, and why not? This is a once in a millenium event and it is hard to get your head around the loss of life and infrastructure. In no way can we Judge their choice of areas to populate. We have had mini quakes on the island, does that mean we should all be building houses on Snafell? No so dont condem the Japanese, they need our support ATM nothing else Link to comment Share on other sites More sharing options...
Alias Posted March 13, 2011 Share Posted March 13, 2011 the plants are doomed to be honest, And the jap gov have not been telling the truth, The reactor core has been exposed to the air, hence the reason the building exploded, add in that particals of radation were found outside the plant that could only come from an exposed core, no3 is is going the same way, and a new plant has started leaking radation up the coast, The plants are doomed, they've used seawater so they're a 'write-off'. They have vented radioactive steam, and acknowledged it. The buildings are containment (designed to fall outwards, like in the videos), the inner core is still intact in pictures shown.

manshimajin Posted March 14, 2011 Share Posted March 14, 2011 I can never understand the mentality of building homes and businesses, let alone nuclear power plants, in areas prone to Tsunamis (major history of them in many areas of Japan). In the UK now, 1 in 6 houses has been built on a floodplain, yet with plenty of non-floodplain land available. Why is it human beings think they can control or outwit everything? Nature always claims things back eventually. Tweek not sure if the following hels to explain things; having lived for some time in Japan I believe that part of the reason for the situation you describe is that approximately 70% of the country is not inhabitable by urban society because it is so mountainous. Also you need to bear in mind the population is 127 million with the majority living on Honshu, the main island. As a geologically relatively 'new country' these mountains also tend to be very steep sided and prone to landslips. The coastal belt is good flat land for building, for commerce, for transport and importantly for agriculture. As elsewhere in the world the Japanese have to live with what nature has given them - i.e. Bangladesh is a highly populated country liable to flooding but people still live there; the low lying Pacific islands etc...etc...). To the maximum extent possible the Japanese have built to withstand earthquakes, trained people in how to behave in emergencies and have a sophisticated tsunami warning system (but nothing could have dealt with the current tidal wave). Every family has an 'earthquake kit' by their front door/escape route, telephone directories have procedures printed in them, many buildings have both designated escape routes, automatic gas switch off and things like emergency ladders to use if you can't get out by normal means. In other words the Japanese are aware of the risk and to the greatest extent possible try to anticipate and manage problems. This one was just too big - but even so when you look at the destruction in Christchurch caused by a 'quake with a magnitude of power 1/8,000th of the Sendai one the techniques are broadly working as they were supposed to. But folk who live on the coastal plain are always at risk just as the people are in Naples or under the shadow of other volcanoes around the world - it is a balance netween the economic benefits and the risks. One thing that I found fascinating is that the traditional pagodas have withstood earthquakes for a millenia. They are built with a large central wooden pole down into the ground and each floor is not attached to the one below or above so that they can move laterally and by knocking against the pole can dissipate the lateral energy down the pole into the earth. Nothing is new... The latest news my friends in Tokyo are giving me is that now the immediate danger is over there is a rush to buy goods from the shops - so for example no batteries are left on the shelves and bottled water has gone. There is quite a bit of concern as to how well some building will withstand a second 'quake of similar size - apparently lots of structural checks are beginning to be done. The people are concerned about the nuclear power plants but unlike the emphasis given to this issue in some western commentaries the Japanese themselves at the moment see this as one of a whole host of pressing needs - not the least of which is to try and find out what has happened to the populations in the areas struck by the tsunami. The death toll is growing rapidly as more areas become accessible. Simply horrible. BTW isn't there a potential hazard for the IOM from tsunamis if the western part of the Canary Islands detaches and falls into the Atlantic - apparently this is a real possibility within 'geological time'....
