HAVANA: Ehm... Myslim, ze treba ve Fukushime se to skrz containment dostalo za par hodin - a to ne proto, ze by byl poskozenej zemetresenim, ale proto, ze ho proste vybuch vodiku rozmetal - a lautr to samy se stalo i v Cernobylu, kde ten vybuch byl navic tak silny, ze do atmosfery vyletela vetsina obsahu reaktoru vcetne grafitovejch tyci (ve Fukushime to z vetsi casti "akorat" vyteklo do more)
Podle mne je to spis psychologicka, nez fyzikalni ochrana lidstva, abych to rekl tak nejak kulantne a nesiril poplasne zpravy - hadej kolik podobnych konstrukci po svete jeste jede na plnej kotel a lidi kolem chodi a usmivaji se stestim, jak maji cistej zdroj energie? ;-)
A abych neplacal do vetru jen tak bez podkladu, tak tady mame jeden docela peknej souhrn jedne celkem autoritativni studie:
The U.S. Nuclear Regulatory Commission (NRC) in a 1990 study of the risks associated with severe accidents at U.S. nuclear power plants concluded that none of the five different designs it analyzed were capable of remaining intact during a severe accident. In another NRC study of 24 U.S. reactors using General Electric's Mark 1 containment design, NRC concluded that "failure within the first few hours following core melt would appear rather likely."
