it has nothing to do with scientific knowledge, it is about is the vessel is broken as it was reported by the Japanese Authorities. the news media cannot do anything other than give us the information they get.
nobody is able to take a look at the vessel other than the people actually working at the site. and they reported the vessel was damaged at the last explosion and that radiation levels are rising.
thats the latest news i have been hearing,
but here on JREF some wannabe experts claim, oph its nothing....... the media is fearmongering etc etc. laughable.
