- ◯ The Fukushima Crisis 15 ; Far Beyond Chernobyl 恐怖のメルトダウン連鎖
the first machine is assumed to have damaged about 30 percent and the third machines to 70 percent and the second machines by about 25 percent as tokyo electric power company made it public.
this is called a cladding tube with which the part that is called the pellet of the fuel rod is covered.
it is shown for what can be done with zirconium alloys to melt, and to have damaged the pellet.
hydrogen is generated reacting with water, and the nuclear fuel expands, it arrives at 2800 degrees, and the zirconium in this cladding tube melts when it begins to melt by 1800 degrees, and it becomes a high temperature in addition when it becomes 1200 degrees. this is meltdown.
it doesn't occur, and the explosion explodes easily also if it is a little spark if there are a in any way or nor houses where the fire started though the explosion occurred in the hydrogen that leaks from the nuclear reactor and containment in 1 and 2-the third machine though it returns to speaking hydrogen.
i think that part has melted to the pellet. and, it was full meltdown in the first machine by which the molten state of this pellet grasped the scenario in the future three days ago.
it is assumed that it stands in the fuel rod bulrush. is it thud suddenly l which it is under of what when falling?water in the bottom of the pressure vessel is rapidly heated, it makes momentarily, it evaporates, and the steam explosion is caused.
even if it happens in which nuclear reactor at what time when, this steam explosion is really happen.
the pressure vessel in part heart 'in a strong nuclear reactor that consists of a stainless double layer system is first destroyed, and there is a possibility of easily blowing off even containment 《 the structure to cover the steel of three centimeters in thickness with the concrete of two meters in thickness) that exists in addition on the outside in the impact, too with the steel of 16 centimeters in thickness when this steam explosion is generated.

the different asset class definitions are widely debated, but four common divisions are stocks, bonds, real-estate and commodities. the exercise of allocating funds among these assets (and among individual securities within each asset class) is what investment management firms are paid for.(wikipedia)
