A visitor to the Hiroshima Peace Memorial Museum views a photo of the aftermath of the 1945 bombing. Carl Court/Getty ImagesBecause several generations have passed since the atomic bombings at Hiroshima and Nagasaki – the only use of nuclear weapons in warfare – some may think the threat from nuclear weapons has receded. But international developments, including nuclear threats from Russia in the war in Ukraine, have brought a broader awareness of the vulnerability to global peace from nuclear e
and it s concerning to me they were not able to keep it out. hopefully they ll be able to keep the levels from going higher. if they have a release of radioactive water. if they can t contain the radioactive water they re getting out of that it gets in the ocean, that s a concern. because it once those get into the sediment, they re there. i want to thank you for giving us your expertise on it, professor, thanks so much for joining us this morning. thank you, kiran. ahead on american morning, banks may be cutting your perks as they face the new laws. cash back, miles, what exactly rewards you might be losing. and so-called super bugs are cropping up across the country. its breeding ground is the hospital. we re going to explain. 20 minutes after the hour.
of the reactors and radioactive water is spilling into the ocean. what does it mean for the containment efforts? joining us from atlanta, professor cham dallas at the university of georgia. in fact, he also led expeditions into some of the most contaminated areas of chernobyl. welcome to the program. thanks so much for being with us here this morning. good to be here, kiran. i m going to run down some of the latest problems reported out of these reactors. and you can tell me what they mean. first of all, the rise duriing temperatures in reactor one. the number one thing they have to continue to do is keep water around the reactor cores. and any time there s a rising temperature, they re having difficulty cooling the reactors. if there s not going to be any more melting down, they re going to have to keep water circulating and keep the temperatures down. they actually had one of the trade groups in japan say it seemed to be they were dealing with perhaps at least some
my guess or prediction is they had partial meltdown from the top down. kind of like candles do, they melt from the top down. they uncovered those reactor cores a little and so they melted from the top down, which means the pellets would have filtered down to the bottom. which means they could be reacting with each other. right now. right now. but we don t know. okay. we don t know. cham dallas, thank you so much for helping us all understand what s happening there today. thank you. now let s watch this. my understanding is you get blurry eyes, your heart slows down. just kind of like a numbing effect. a numbing effect. have you heard this story in that was wildlife expert jack hannah describes what happens when you re bitten by a cobra snake. why are we talking about this? because one is missing in new york city right now. it disappeared from the bronx zoo. it has not been found. the big question, where is it? and then, do you remember on friday we showed you former h
relieve the pressure and avoid a meltdown. i m joined now by cham dallas, professor of disaster management at the university of georgia. william. thank you, will. professor, we know that the problem lies inside the cooling system, in at least a couple of the reactors. what are officials doing to avoid disaster? well, right now, the they have backup systems, and some of the backup systems haven t gone the way they wanted. the thing to remember is that they have already stopped the reactor. they got the control rods done into the reactor so that there s no more fission going on. however, they haven t been able to dissipate the heat. it s like a stove, where you turn the heat off, it s going to be warm for a while. the same with a reactor. they have to get that heat out of there. unfortunately, some of the cooling systems have not gone the way they wanted. so that heat has to go somewhere. what they re doing now apparently is releasing it in the form of steam. here in the united s
