Port-A-Nuke
Roland Piquepaille writes "Researchers at the U.S. Department of Energy (DOE) are designing a self-contained, tamper-resistant nuclear reactor that can be transported and installed anywhere in the world. In 'US plans portable nuclear power plants,' New Scientist writes that the sealed reactors would last 30 years and deliver between 10 and 100 megawatts. The largest version would be about 15 meters high and 3 meters wide, with a weight of about 500 tons, allowing for transportation by ships or very large trucks. The DOE thinks that this kind of nuclear reactor -- named SSTAR for 'small, sealed, transportable, autonomous reactor' -- would help to deliver nuclear energy to developing countries while significantly reducing the risk of nuclear proliferation associated with the use of nuclear power. What do you think of this idea? Is it a good one or a crazy one? Leaving a nuclear reactor in a developing country which can potentially become unstable during the 30 years of service of the reactor doesn't seem to be terribly safe.
Read more before deciding. Anyway, there will be no prototypes before 2015."
A portable nuclear reactor? Cool! Just sling it over your back and go!
Sarcasm aside, "portable" may be stretching it for something that weight 500 metric tons. "Self-contained" would be a better term. Which would be an impressive feat if they can pull it off. Most of our existing reactors require quite a bit of supervision to ensure that they operate within expected tolerances. The safety systems should kick in if anything goes wrong, but the power going out is enough of a problem in of itself. Of course, most of our reactors are pretty old tech, so a self-contained reactor may be possible now. I think it would be kind of cool if every suburb could have one of these things.
Not sure about the whole third-world idea, though. All I can say is, it's better than letting them build their own reactors. At least with these, we'll 100% KNOW if plutonium is missing.
Javascript + Nintendo DSi = DSiCade
I can tell you that US Navy subs have had few catastophic disasters, and perhaps none at all for a long time.
So I think that is a good proof of concept for portable nuke power plants.
With the right type of manufacturing technology, one can make the fissionable material very hard to get at.
I fully support much more use of nuclear power everywhere in the world.
eat shiat and bark at the moon
Just add C4, Dynamite or Fuel and Fertilizer if you're really hard up.
Hard up for what, seeing paint scorched? The gov't is already pretty good at building reactors and transportation vessels that stand up to such attacks. The real threats are regrettably from the simple and common anti-armor weapons.
Personally, I still think the helium-cooled pebble bed reactors would be better for long-term operation.
I can't believe that anything having to do with steam will survive 30 years without maintenance. Corrosion happens when you have water. High-pressure helium (or other unreactive noble gas) is a safer cooling solution.
Also this whole breeding plutonium thing is real proliferation risk. The article says the reactor is "tamper resistant," but I don't see why someone couldn't bore through the side of the thing and take out the fuel rods. I think a non-breeding solution would be safer.
The biggest issue with the "pebble bed" concept is the physical removal and addition of the pebbles, which is requires too many moving parts to be sealed.
Certainly you could work out some sealed solution to a long-term pebble bed only having a part of the core fissioning at any point, using some sort of neutron absorbing rods or liquid.
Too bad this story was reported on earlier.... though the placement of the reactor has changed slightly....
Reading the article linked to from /. story about pebble bed reactors would show you that the turbines are driven by helium in the primary loop. There is no secondary loop. Water can be used as precooling before the helium is recompressed, but water or steam is not required.
Yes, one day I may actually learn to spell...
They satisfy all three of your requirements.
Not quite true, I have most of my apartment converted to the spiral flouresent bulbs, the one exception is the light in my bedroom. The reason I haven't converted my bedroom is that the compact floresent bulbs do have a 1 to 2 second startup delay, and I suffer from night-terrors. My fiance needs to be able to get a light on immediatly when I go into one of those, as its the only thing that snaps me out of them. Considering that I have been know to both do damage to the room, and to attack her during a night-terror, we both want to have no delay in getting that light on.
But, other than that one light, ya, compact floresent bulbs for the rest of the place, they are cheaper to run, and personally, I prefer the light they give out.
Necessity is the mother of invention.
Laziness is the father.
As for countries like Iran, Hussein's Iraq, Pakistan, etc, they were broken up for a reason. Very simply: we can't trust them as far as we can kick them. September 11 only proves that.
Odd. You don't mention either of the two countries that actually had anything to do with September 11: Afghanistan and Saudi Arabia.
