Containment Shell News Today

Line site. worse than that is the chance the fuel will catch fire. its hot and it can cumbust. the way this reactor is designed, mark one reactors, they dont have a container around the spent fuel pole. its a real concern. the fire could liberate as much radio activity or even more than the accidents that are occurring at unit one, two and three. >> lets come back to that point. six units in distress. three of them the issue is spent fuel rods which are not protected. not inside a secure contain...

Worst yet. international atomic energy agency says theres evidence it breached the primary containment shell. that means more radiation could be leaking from that unit. the iaea says radiation levels at site have been decreasing. people living within 20 kilometers of the plant have been evacuated and are lining up to be scanned for radiation. a no-fly zone has been established around the crippled nuclear plant for 30 kilometers. global economic fears, the stock market plummeted today because of ...

Wind continues n to go north bu at chernobyl the winds shifted on them in the 8 days. it came down on the people they were evacuating. it could be a significant issue. >> whats the name difference? is it the name difference for containment shell between chernobyl and plant? >> i think the main difference is the capsule around it. we melted the core had major releases at three mile. >> three mile island. >> the reactors go along the left radioactive iodine and the left gasses there are. so at thi...

Only when the nuclear fuel melts through the inner most chamber but not through the outer containment shell. it is a very serious situation there and seems to get worse by the hour. more details as they become available. jenna: we are watching the developments on that. engineers are racing to prevent a meltdown some say at a nuclear plant in northern japan. if they cant, and that is a strong cant we ream i dont know what is going to happen. there is a possibility that tens of thousands could get...

Chernobyl was a big deal because that was a full-blown meltdown. the russians and soviets, their system in chernobyl wasnt as advanced as the japanese. they had no containment shell around the reactor, the japanese do. the soviets built with graphite and the japanese do not. >> at cher global was an he can motion and fire. the graphite which moderated the core of the he actor actually burned and was thrown thousands of feet into the air. and that spread radioactive material across a wide area in...

The numbers 5 and 6 appear to be the least troubled. so those, apparently, are stable. the big problems are at reactors 3 and 4. smoke seen rising from number 3. theyve evacuated all workers. theyre not clear if its come from the reactor itself, but the fear is, the pressure is rising that steam is coming out. remember, number 3 is the only one that uses plutonium. that is much more toxic than uranium. and the concern is, because the containment shell is damaged that you would have that radioact...

The only one that has a combination of uranium and bl plutonium which makes it both hotter and ultimately more dangerous if it releases or melts down and releases everything inside, an explosion there, possible structural tear inside that, as well. but now we come to the big one, the one were all focused on so much, which is reactor number 4, here weve had an explosion and those repeated fires and the problem, once again, as weve been talking about all along is not this part, this part was shut ...

Them at this minute. the reactors at fukushima, were concerned about mainly two of them. the number 2 reactor and number 4 reactor. lets begin with number 2. the pressure there is said to be falling and radiation level rising. thats a sign, experts say, that the containment shell might be breached. on top of that, the fuel rods in number 2 are fully exposed. the pool that stores the rods is boiling. if it boils enough and evaporates, it means more radioactive material will be spewed into the air...
