1。Situation is serious. This is definitely a worse accident than Three Mile Island. TMI only affected one reactor and there was almost no contamination outside the plant. At Daiichi at least 4, potentially all 6 reactors at the site are facing serious problems and there is high level of radiations LOCALLY at the site (not outside the 20-30 km protection area, there levels are low).6 }1 N/ A- g: @; Z" q
) v9 I" i7 G# U" ?! t
2。No-where close to a Chernobyl event. At Chernobyl the reactor blew-up and a 10 day fire spread large volumes of contaminated materials over large distances. At Daiichi the reactor is surrounded by a concrete structure and the reactor is a water moderated reactor whereas Chernobyl was graphite moderated. Thus there is no graphite to sustain the fire and there is a protection vessel surrounding the reactor so a Chernobyl event is very unlikely.

They have not managed to keep the fuel rods in water all the time and this is critical and improving cooling water supply is the current focus.& ~( D! _" f% G/ V( P9 i$ N- ]$ h

1 b7 [# @7 A3 P! j4 N4。The spent fuel storages, not the reactor, the currently most serious problem. Fuel in the reactors are probably melting down and some fuel could potentially leave the reactor into the ground and then leak out. This is a serious scenario, but likely to only have local effects possibly in the 20-30 km protection zone. The main worry is instead the storage facilities for spent fuel. They are located outside of the concrete protection vessel and they now overheat. Wouldn't they manage to reestablish cooling, there could be a fire and significant radioactive substances could come into the air. If they manage to reestablish cooling this issue should stabilise in 2 days.8 ~7 ]8 J+ c$ t3 s9 O3 a; {

5。The people on the site deserve our thoughts: The engineers/firemen working at the site are exposed to extreme danger with high radiation levels and constant exlosion risk. They deserve our support. % x, ^9 b/ h) s/ W4 M& M3 Y/ W

听起来还算靠谱。再过几天,几个炉都冷却了,也就差不多了。

1。情况严重。这无疑是一个坏比三哩岛事故。 TMI的唯一受影响的一个反应堆和几乎没有污染的厂外。在第一制药至少4,所有6个可能在现场反应堆正面临严重的问题,并有局部的辐射在现场(不20-30公里以外的保护区,有水平低)的高水平。' m& s0 B  S; p: m

* G  x" v9 |7 R4 P9 m. H2。无在靠近切尔诺贝利事件。在切尔诺贝利的反应堆爆炸行动和10天的火势蔓延的污染物质长距离大容量。日本第一反应器的四周是混凝土结构及反应器是一种水慢化反应堆,而切尔诺贝利石墨慢。因此,有没有石墨,以维持火,有一个保护船只周围的切尔诺贝利反应堆所以事件的可能性很小。3 Q9 i7 I6 Z5 {+ H! x: p8 O

3。重新建立冷却是关键。它需要4-5天凉/慢反应器一个稳定的水平。为此,您需要水,这一直是问题。他们没有设法使水中的燃料棒所有的时间,这是关键,提高冷却水供应是当前的重点。4 [/ G3 ?& U* s+ }% [2 a

) V$ P3 G8 P' Y) X! l' G$ y/ @/ S4。乏燃料储存,而不是反应器,目前最严重的问题。在反应堆的燃料可能是熔化和部分燃料可能将离开地面,然后反应堆泄漏出来。这是一个严重的情况,但可能只在20-30公里的保护区局部效应可能。主要的担心是不是乏燃料贮存设施。它们位于船只的具体保护外,他们现在过热。难道他们不会设法重建冷却,有可能是一个重大的火灾和放射性物质,可以接触到空气中。如果他们设法重建冷却这个问题应稳定在2天。
