That structure had completely surrounded the other containment structure, like containment within containment. the inner is primary containment, four to five feet thick concrete with inner steel liner two inches thick of steel to ride integrity against release of radioactivity. >> it is that primary containment vessel you are worried may have been compromised by the recent blast? >> initial reports hopefully turn out not to be true. initial reports are part of the containment called the pressure suppression pool or the toris, the round metal donut looking thing has been compromised. we don't k...

On reporting this the past few days, is the internal containment vessel around the reactor, there is also a secondary containment vessel which is in effect the building that surrounds the entire reactor complex. for us to have had a significant radiation leak into the environment, does that mean officials are saying both of the containment units have been breached, both the outer building and smaller containment vessel around the dome? >> that's a good question, not clear at all, and not clear the smallest has been breached yet. because the core nuclear material in there which had been an on-g...

To ride integrity against release of radioactivity. >> it is that primary containment vessel you are worried may have been compromised by the recent blast? >> initial reports hopefully turn out not to be true. initial reports are part of the containment called the pressure suppression pool or the toris, the round metal donut looking thing has been compromised. we don't know whether it was by the third blast the facility experienced or some other mechanism. pressure is reported to be dropping from inside containment. that would suggest that gas is leaking out somewhere. >> forgive me if i get t...

Would be maintaining constant and not decaying as it is or reports show that pressure is dropping. >> in terms of that word containment, it is a word we use commonly not as jargon, it is meant to be several types of structure. containment could be the outside building that surrounds the reactor as a whole. that was what we saw the explosion do so much damage to in the first two explosions, but containment also refers to the smaller containment around the core itself, around the reactor itself? >> that's correct. these type of plants use defense and depth. there's two containment structures. th...

Facilities, so even after the blasts they kept up the effort to cool those facilities down to prevent further damage to the fuel rods, any further meltdown. with the type of damage that you are worried about that you're saying this lack of pressure might indicate, does that mean they will not be able to continue to cool this down? that they will not be able to essentially keep working on it to make it more safe? >> that's a good point, because if the containment is breached the way it has been suggested, not only can radioactivity escape through the pathway, but the sea water, the water being ...
