| Worst that could happen?
1 Uncontrolled nuclear explosion. Probability = less than 1 in a billion, billion. There is no initiator for the reaction to go super-critical which is needed for a Hiroshima type of explosion. It just wouldn't ever happen unless there was a complete lack of moderator, and there was a primary ignition source all around the chamber at the exact same time(shaped charge) that would compress the U235 enough to make it explode. Very far fetched.
2 Uncontrolled fission boil off. Probability = very very low. Containing hot, radioactive U235 is hard to do. Once it changes state from a solid pellet to a liquid and starts to flow, everything around it - pipes, tubes, valves, seals, etc has already come apart. If it didn't and the U235 was able to be contained in a vessel that allowed the Uranium to pool, you could have a Uranium boil off. The Uranium changes state from a liquid to a gas, and boils into the air. This is a very bad thing, almost as bad as a bomb, but the fission byproducts are not scattered as badly as with a bomb. As with any boil off, they condense, and come back to earth(Uranium is very heavy, even as a gas), and many of the constituents of the boil off are also very heavy and stay close to the ground. Again, still bad, but not too bad.
3 China Syndrome. Probability = Dependent on what it's sitting on. Uranium will etch right through concrete and steel if it gets hot enough. Both in heat and radioactivity. Once it gets through the containment housing, it's in the bedrock below, which is what all reactors are built on. Nature will take it's course, and the Uranium could go down quite a way. We really don't know because we've never had a true China Syndrome happen, so it's all pretty sketchy. I doubt it would go down very far, but it would spread out a way. Hard to collect, hard to clean.
4 Chemical explosion. Probability = pretty high, depending on how far they let it go. We've already had one H2 bubble blow, and the other reactors are surely close to the same. Venting may help but at this point, venting and blowing are two side of the same bad coin. It puts a bunch of radioactive junk in the air, but it usually doesn't go very far, or last very long. The Chernobyl explosion blew the casing apart, and they had at least a partial Uranium boil off which made the release of the radioactive gases far higher than is normal. It was the worst case scenario of the chemical explosion that could happen, but at least it wasn't a fissile reaction, so they were lucky there.
5 Chemical/radiological spill. Probability = almost certain in the event of a SCRAM. Even small leaks are tracked, and it's just about impossible to SCRAM without a small release of some radioactive material. Stuff happens. | | Offline | | |

We have responsibility to deliver products to patients even in such situation, especially those in disaster area. My office is in central business district, but today we worked in limited light to conserve energy, threatened by repeated aftershocks. We are enduring enormous difficulties that we haven't experienced in recent history. We Japanese people appreciate concern and well wishes from around the world much more than you could possibly imagine. Many thanks.." | | Offline | | |

| Citāts no viena raksta:
Monitoring of the Daiichi plant has detected several signs that at least a partial meltdown may be occurring, according to Japan's nuclear safety agency, including high levels of hydrogen inside reactor buildings and radioactive cesium detected outside the plant. This could be caused by the melting of fuel rods inside the reactor, experts said.[ Šo ziņu laboja Onka, 14 Mar 2011, 15:19:54 ] | | Offline | | |

Wikipedia
Japan’s Asahi Shimbum newspaper reported early Saturday that radiation levels per hour in the area near the front entrance of the No. 1 Fukushima plant reached 0.59 micro Sievert, which is eight times the normal levels. The central control room of the reactor recorded radiation levels 1,000 times the normal level, which would be approximately 70 microsieverts per hour, or 7 millirems, according to calculations by msnbc.com.

| Atgādiniet kas notiek šobrīd ar Černobiļas degvielu???
Saprotu ka daļa sprādzienā tika izmētāta apkārtnē.
Bet kas ar pārējo?? Aizgāja augsnē vai nē?? | | Offline | | |

Ak jā nafta šon noslīdējusi par aptuveni 2% un te visādi eksperti runā kad kritīs vēl... jāskatas tālāk kā viss atrisināsies, jo pat reitingu aģentūru cilvēki rakstos raksta, kad nav īsti vēl skaidrības cik lielu efektu tas viss atstās uz Japānu... | | Offline | | |
