[QUOTE="Lee Dickinson, post: 24047, member: 79"] Re: Attempting to bring clarity to the nuclear problems facing Japan Phil, I was hoping we'd hear from you. Would you mind telling me, when they're talking about pressure buildup - I assume the turbine steam has been vented and the heat transfer systems (the cooling towers and their loop) are destroyed. Does the "pressure buildup" refer to pressure within the containment vessel that results from the boiling off water being dumped directly on the reactor to cool it? Hydrogen: Where did the hydrogen that exploded come from? Was it something the cooling water reacted with? Apparently these explosions took place outside the containment vessels. "Radiactive steam" - I thought water couldn't become radioactive? Does it carry contaminates? What other radioactive gases are of concern in terms of spreading contamination? [/QUOTE]
