-- on how you look at at the Fukushima fifty yen and Japan are just coming back from the brink or -- about to plunge over.
They'll not a size guy is one of the world's best known explainer.
Complex scientific issues such as nuclear science and he joins us now bill good to see is so bottom -- you know what question.
A lot of people of asked me about that the fuel rods in the fact that.
Even if all the water is gone and there's no.
Clear right a suggestion that bad has happened but how do you cool them down again if you if you pour water on -- doesn't at all immediately evaporate in the steam because of the heat.
-- -- when water turns to -- it takes -- away with it when you change from a liquid to -- -- take the -- away and so eventually.
Eventually enough water is pumped on top of this these things they will cool off.
And also how they -- haven't you also now have the electrical devices that are in their are these like many air conditioner -- what -- -- -- -- I think it was a translation.
That you're interpreting it these pumps are electrically driven.
I want to get the pumps working you need electricity.
It's quite extraordinary thing to run an enormous electric wires across a debris strewn landscape that is radioactive.
And then hope that the pumps which were if not submerged.
Certainly in the presence of liquid water from the C.
Have to hope that there was electric motors will be up and running quickly is.
There's an extraordinary help.
Another -- made another email always worry are getting by the way bill is skeptical is whether liquid nitrogen or something like that some.
Extreme coolant could be poured into these things.
And -- while that intuitively makes sense.
Let's just if I may run the numbers.
This stuff is hot.
Beyond what our everyday experience 2000 Fahrenheit.
Maybe 4000 for -- 2000 Celsius.
So the difference between liquid water -- -- room temperature twenties Celsius.
And liquid hydrogen at minus almost minus 200 Celsius that's.
The difference of children -- -- Compare that.
To 2000 and it's -- wouldn't help you that much I understand the idea that it's so cold it would have this great effect but.
Water we really would be -- good thing you know what I think we'll all probably happen is this thing.
People find a way to pave it over with something like cement that absorbs neutrons that's weeks away it's a very very dangerous thing -- Previous guest I think was just extraordinarily optimistic.
OK so -- that that was that was very optimistic you say.
It's extremely dangerous why why can't you just pour the concrete on top of the on top of the -- What would you like to go on and do it.
All of these -- I would fall they got Oprah yeah are probably going to suffer.
If not immediate radiation sickness and death.
Certainly something -- extraordinary health problems in the very near future and the reason they're probably doing it is they've lost everything.
They've lost their houses -- lost their families people disappeared trains full of people disappeared.
So they ought to behave.
Are gonna get in there and do something furthermore my experience people radiation industry nuclear industry are dedicated.
They -- true believers they really want nuclear power to work.
And they will do what it takes to show that it works.
And I'm hopeful that they're right but it doesn't look like this situation is going to be cool down even in the next week for two.
By the way we say we say this noisy mess we say the Fukushima fifty they're actually.
About 200 people that are on a rotating basis going in fifty people at any one time are doing that and -- apparently.
In Japan there is no shortage of volunteers are actually hundreds of people.
That are willing to volunteer and do this extraordinarily.
Dangerous work now.
What another another boy I tell you stories started to go on my hands nobody questions I wanna I wanna get some of the concerns of our viewers in here.
A lot of people say look you had Hiroshima and Nagasaki which are now inhabited places very thriving cities if you will.
These were cities on which nuclear bombs were exploded.
If if you can have city's thriving after a nuclear explosion which spews all kinds of nuclear crap in the air.
Why might there be a possibility of a quarantine of this area.
Two reasons first of all each reactor.
Just as -- rough -- about a thousand times more energy than either of the bombs.
Then the type of material that was thrown into the -- 1945.
Was much less persistent.
Isotopes or types of Adams.
Radioactive atoms are gonna stick around much longer than those early in what people would call for -- Bomb so that's.
In the case of leadership here -- about thirty years and things and come down.
Here it's going to be quite a bit more than and you compare that to Chernobyl a colleague of mine went to visit Chernobyl he had to -- -- -- senator are you a badge.
Two measures radiation yes -- got a tour but he couldn't stay very long because it stole.
24 years later it's still quite radioactive still hot bill -- hey good to see a bill thanks very much for explaining all this coming.
