Merged nuclear power safe?

“This Could Become Chernobyl on Steroids”: Nuclear Engineer Arnie Gundersen on Japan’s Growing Nuclear Crisis

That's on par with the Palestinian genocide. You know, the one that causes massive population growth.

And that chain reaction of exploding atoms that CERN is going to cause any day now.
 
This was a spike. From what i read they are at about 10 millisievert per hour. So multiply all those time by 40. Although you might better off verify for yourself there, as I have so many numbers in mind that I might not give the correct one.

ETA I see MattusMaximus confirmed at 11.9 and now 0.6 millisivert per hour. 0.6 millisivert per hour is less than the background radiation at my old home.

0.6 milliseiverts would be 60 mrem per hour...that would be enough to make a person quite ill with a long exposure...possibly microseiverts.

Why go back?

If they keep this up, their days as a leading industrial nation are numbered.

This is how it works in Germany:

1. Invent awesome technology.
2. Be too afraid to use it or assume nobody will want it ("whe've managed without it so far, what's the point?").
3. Let someone else in another country mass produce it and get stinking rich.
 
Hmmm...radioactivity is terrifying because it's invisible (it could be 'hidden in the raindrops'...that from the Beeb).

Well having seen all the footage of the tsunami I know that actually seeing the agent of my death would surely bring about a beatific calm within me. Yes, much better to see what's about to puree me.
 
NPR generally reports these stories quite well. Their current story (http://www.npr.org/2011/03/15/134552475/radiation-fears-rise-at-japanese-power-plant) indicates to a non-expert (e.g., me) that things are getting worse, and that there is real risk of a "catastrophic" event. The story leaves me with the impression that this catastrophic event would release serious radiation into the atmosphere. I'm also left with the impression that a breach is already releasing radiation into the atmosphere.

I'm trying to work right now. I don't have the time to read carefully, nor do I have the time to research these topics further. How much of this do we know to be true? How much to we not know? What is our best guess? How large are our error bars?

Thanks all. I appreciate your time, knowledge, and beyond all, sober assessments.

My suspicion is that my impressions are wrong. I also suspect many non-experts are unable or unwilling to dig further are left with similar impressions.

What I really love about that link is the picture. It appears to be another angle on this explosion. What exploded? A natural gas storage tank at an oil refinery. And yet, they're using that as the picture for a story about the dangers of nuclear power.

The irony, it burns! (see what I did there?)

AWESOME!!! thanks for finding that other pic!
 
One of the new conspiracies is that all the news is showing only old footage of the plants. Anyone have newer pics or know why the footage might be old?

Is there a no fly zone?

You forgot one of the middle steps: Keep pumping money into it at all times. Developing the transrapid and then neither selling or building it is all fine, but the fun don't really start until you build massive test tracks, maintain them for several years whilst technology elsewhere races past you and then fail several times over in getting at least a small commercial service established anywhere.

Rasmus,
who would have loved riding that thing to work every morning.
 
So, what happens if those storage pools run dry?

These are not in a containment vessel.

I'm usually a champion of NPR as a news source but their reporting on this story (at least on Morning Edition and All Things Considered) has been appallingly bad, spreading all kinds of misinformation, though I don't necessarily think its deliberate. It's just sloppy. I'm considering sending a nastygram to Richard Harris in particular, for his sky-is-falling reporting on M.E.

I think you can safely ignore what they say on the subject.

Also, this is how anti-nuclear people work here in Germany:

1) Complain about nuke power being somewhat subsidized, but never mention that renewable energy is highly subsidized

2) Complain that the operation of nukes costs so much money, but then go ahead making massive protests & demonstrations at, and tie themselves to, the train tracks of the Castor transports. This causes extreme delays in the transport, requires way more police personnel then normally required for that longer time. And last time, the managed to tie them to the tracks in such a way that workers had to actually cut these tracks apart and repair them afterwards.

3) Complain about the fact that there is no suitable terminal storage facility, but actively work against getting one built.

4) Complain about old, unsafe reactors, but force the government to ban companies from building new and safer ones. At the same time this also causes the companies to keep the old ones running even longer, prolonging the risk.


For example,here in Germany, if you have a photo-voltaic system running (solar cells), the energy companies are forced to buy that electricity, and the PV owner gets about 43 Euro-Cent per kilowatt-hour. Regular electricity costs "only" about 13 or 14 Euro-Cent per kW/h. And in that price there is the added premium of 3 or 4 Cents per kW/h included that results from the "Erneuerbare Energien Gesetz (EEG)", which means "renewable energies law".

This means that _everyone_ has to pay a premium to keep that system alive. I'm absolutely sure that if those people who have contracts for getting only renewable energy instead of the regular energy mix, would have to pay the _full_ price, they surely would be the first ones to scream "we want nukes!". After all, that price would be at least 50 to 60 Cent per kW/h, if the PV owners already get 43 Cent....

And they have the balls to complain that nuclear energy is partially subsidized. Hypocrisy at it's finest, i tell you.

Let's not forget that they also want to have electric cars everywhere instead of combustion engines. But somehow they don't spend a minute thinking about where that amount of electricity should come from. Let alone the problems of manufacturing and disposing suitable batteries.

I simply fail to see how all that is supposed to work, and to be achieved, in the long run. Without exception they all completely ignore the energy, material, production, build and space needed to switch to renewable energy completely. For them, wind-parks and solar-panels seem to grow on trees, install themselves, hook themselves up to the grid, and need no space at all. And of course these technologies are obviously able to produce electricity 24/7, regardless of the fact that most of the day there isn't enough sun or wind.

But hey, i'm happy to switch to renewable energy. Bring me a bunch of anti-nuke people and a bunch of stationary bicycles with fat dynamos, and i'm sure i can manage to hook them to my distribution box. Presto, renewable energy!

Greetings,

Chris

So, what happens if those storage pools run dry?

These are not in a containment vessel.

Depends on a few things...first there is typically about 24 ft or 8 meters depth of water measured from the top of the spent fuel--shields everyone in the building. If this is still there, then it will be a bit before it will boil away. Natural circulation will keep it mixed somewhat. If the fuel is very old, it won't be a problem...however, newer spent fuel will boil the water and there will be a zirc hydrogen reaction causing similar problems we have already seen. Worst case, the pool boils dry and we could get a zirc fire and major release and it would be difficult approach the plant as the radiation levels would be very high. Just pumping water in the pool will keep this from getting too bad but there would be some radation release as feeding and evaporation will take a minimal amount of radioactive stuff along.

So in the units I am used to working with, this is 40 Rads per hour. Not bad unless you are leaning against it. Here is a rule of thumb we call the curie-meter-rem rule. It is supposed to be close for Co-60 gamma sources. A one curie Co-60 gamma point source is 1 rad per hour. Double the distance and you quarter the dose.

If it is a 40 rad/hr point source, then it is 26 millirads (.26 millisieverts) per hour a meter away. At ten meters the source is insignifigant. I'm sure it is more than a point source, but it is not the monster that some pople are making it out to be unless it is on fire and spewing out lots of activity.

I think I learned that thumb rule the same place you did, USN nuclear power sub service.

But we are not dealing with point sources in this case, from what I can tell, it's outside the containment between or next to one of the buildings. The sources that have been quoted don't specify the location of the source.

Those hydrogen explosions that have been on the news and TEPCO admitting that the core water level in the three reactors are half full, recovering from dried and half full, indicate to me that this is a full on complete meltdown in all three reactors.

In two of those they are admitting that there is fuel damage and they are venting the containment, which means that we have a continuing uncontrolled release of fission products to the atmosphere.
