OMG... This is some incredible footage....shot from street level as the water comes rushing in. It's hard to get a grip on how immense an event this was until you view this. Up close and personal with a tsunami. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

The size of those large vehicles and the houses just being swept away shows the force of that water ..... If I didn't know better, You swear the houses were toys to be played with and the water was having a blast. But It shows the force water can have and those waves were typical for a sea quake of around that size, But still their nothing according to scientists who say a long run out slide like has happened to the Hawaiian islands in the past could make a megatsunami, They said the size would be hundreds of meters tall. Such a wave had hit Australia once long ago I read. The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

Radiation at the plant now "10 million times the usual level". Is it okay to worry now? Plant evacuated yet again. Radiation burns occured on workers at "12,000 times the usual level" Can we call it a meltdown yet? Janice |

In the news was mentioned the metdown is already in progress. The radiation level has its own language. With each crime and every kindness we birth our future. |

S^S These numbers seem high; do you know what normal numbers would be? I think being worried is acceptable now. One of my sisters has a son and a daughter in Shanghai right now, but I know she wants them back here now. None of this is good, none of it. celttooth |

S^S Japanese standards talking about 250 millisievert a year. Now its 1000 per hour. With each crime and every kindness we birth our future. |

S^S The prevailing winds at those latitudes blow west to east - away from China and towards North America. Shanghai should be safe from whatever happens at Fukushima. From a stationary source, radiation levels drop exponentially as distance increases. Levels inside the building where the workers are trying to get the pumps going may be high enough to cause illness, but a mile or two away there is little danger.

S^S Yes, Shanghai being in China should be quite safe. The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

S^S Normal is 3 milliseverts per year. readings are 12,000+(bad reporting, but this seems to be the hourly number as has been said.) What was coming out late last night is, these levels were at the turbine outlets(cooling ponds) and surprisingly were in reactor #2. reactor #3 seems to be more dangerous and generally in worse shape.

Exactly s^s. Japanese standards are 250 a year. 1000x24x365 = 8.760.000 With each crime and every kindness we birth our future. |

Exactly s^s. 250 per year maximum for a nuke plant worker may indeed be correct. the 3 "normal" may be exceeded due to typical exposures from electronics, dental x-rays, and normal living of life. Some regional areas may be higher. But "normal" of 3/yr seems to be the standard. The levels reported are far beyond fatal, even short term. I am trying to find a site with localized radiation readings, and not having any success. News is simply spewing the numbers from japan(which come from a suspect company) and we are being told not to panic. The problem I have is I am not panicing, just trying to find some actual numbers so I can actually make my own determination. If local numbers go to 200/year no worries. If they go up into the 100/hr. Concern time. Start taking precautions, plenty of non-rad iodine, stay out of the rain etc. Again... numbers need to also reflect "over how much time". And the news is REALLY sketchy there. latest report.. radiation levels are only 100,000 times what they "should be". not sure what "should be" is for a nuke cooling pond. Janice |

BBC says: "A spokesman for Japan's nuclear watchdog, Hidehiko Nishiyama, said the level of radiation in puddles near reactor 2 was confirmed at 1,000 millisieverts an hour. "It is an extremely high figure," Mr Nishiyama said. The radiation levels are so high, that emergency workers near the contaminated water would have received four times their maximum annual dose of radiation in just one hour. The BBC's Mark Worthington in Tokyo says the erroneous report has created more confusion around a crisis that is already causing widespread unease in the country. On Sunday, anti-nuclear protesters held a large rally in Tokyo, calling for change in Japan's nuclear industry. Meanwhile, efforts are continuing to locate the exact source of the radioactive water leak, amid concerns that the water is leaking directly from the reactor itself. Earlier, Japan's nuclear agency said that levels of radioactive iodine in the sea near the plant had risen to 1,850 times the usual level. " Janice |

Well It's good to know that the radioactive iodine will be something else in about 18 days, Of course what It will be is the question? And Yeah, I can see someone adding a zero on to a press release, It wouldn't be the 1st time that has happened, Nor the last. Japan will have to do something to make the remaining plants safer and provide for an input power line from a far away power plant that can supply tertiary backup power in the event the secondary backup power has failed, Plus find some way to wall off the most vulnerable areas of the power plants near the coast to keep the tsunami waves from destroying the pumps, diesels & other needed areas that are fragile, That or build new plants behind something very tall or just on higher ground. Out here We have a few along the coast that are said to be over engineered, I'd hope the NRC can find out with computer modeling how well they'd perform under similar circumstances to Fukishima... Or We'll all wind up Fuki'd maybe... The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

They should start by moving the back-up diesel generators to the side of the buildings away from the coastline, if they are not there already. Donald Infernal Optimist / Submariner, retired |

I think in some cases moving the diesels may not be possible as It depends on if there is room to do so with. The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

You design it that way. If there is no room for a diesel generators behind the buildings, then there's insufficient room for the reactor. Both coastal plants here in California are designed that way. The back up generators are behind and above the reactor containment structures. |

Well that's good to know, Hopefully their up higher than a 36' Tsunami can reach, In Japan at Fukishima, Tepco went for the most likely wave height of only 18' according to the TV News, Instead of the worst case scenario of 36', Which is about what hit them, Maybe they'll fix this, Among other things, Of course now they have to somehow get control and seal It up. I wonder can something so melted be taken apart? The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

Of course now they have to somehow get control and seal It up. I wonder can something so melted be taken apart? Oh, yes. They got the Three-Mile Island reactor taken apart and cleaned up, they can do for these plants, too. The question is how much melting has taken place - have the zirconium alloy tubes melted enough to allow the ceramic fuel pellets to leak out, or have they just deformed? Will they be able to remove the fuel rods by themselves, or will they have to take out some of the support matrix as well? Those are the kinds of questions they will be looking to answer, after they get everything cooled down and clean up the contaminated water in the containment. It may take years to clean up these 4 reactors, but it can and will be done. Donald Infernal Optimist / Submariner, retired |
