Nuclear power Definition and 116 Threads

Well we all hear of fossil fuels being depeleted soon. and the fact is that we don't have a lot of radioactive material around. So has anyone done a study on how much radioactive material is left that can be used in reactors. Including estimates on how long we have until that's through. Also...

Nuclear Power Plants and the Sun I need some help again...:frown: 1. What are the fuel sources? 2. How is the fuel used to produce/release energy? 3. What are the similarities in the way they produce energy? 4. Are there any health hazards associated with the way they produce...

Assuming the current anti-nuclear public/political climate remains in place and no new nuclear plant sites would be allowed (nor within a reasonable timeframe) why not just simply increase the existing capacity? For a hydro plant it makes sense there is only so much water that can be...

How long does it take for a nuclear power plant to be built and to have its first reactor come on line? Let's start the time line at basically when the permit is requested and end it when the first reactor goes fully online. What kind of time period are we looking at there in the best case...

I just read some stuff on pyromagnetic generators, and my first thought was why don't they use the pyromagnetic generators in nuclear power plants and in any power plants that use thermal energy? You would skip conversion from thermal to mechanic, and then from mechanic to electric. I'm sure...

What are 1st, 2nd, 3rd, and 4th geration reactors? How does nuclear fission work (in regard to alpha particles and beta particles)? Thanks

One of the waste products of many nuclear power plants is heat. They send it towers in the form of steam and some have dumped heat into nearby rivers. The basic problem is that when you use steam heated by a nuclear reactor to power a turbine, the steam says fairly hot while no longer being...

President Bush gave a speech this week which, in so far as the nuclear power industry is involved, can be summarized as: Nuclear power is good. Let's make more. (In his usual inapt kind of way). So, who thinks this is for real? Will we be seeing a jump start in nuclear power plant...

Most commercial nuclear fission reactors are large, on the 1000MW order of magnitude. Some of the early experimental reactors were small, and the reactors in nuclear submarines are relatively small. I understand that the Navy even has one very small (crew of 7 people, 400 tons v...

What do you think about nuclear power? How dangerous is nuclear power plants? and from a physics point of view, how efficient is nuclear power c.f. coal-powered plants etc.? and what about the advantages? There are no greenhouse gases released but what about nuclear waste?

Is there any reason not to build nuclear power plants underground? All of the ones I know of (http://pravda.ru/main/2002/02/05/36613.html) are all above ground - if there’s a problem like meltdown, it gets scattered all around. My thinking is that if we build these things underground this...

Hi, all! I am working for the disclosure of secret technology. The technology exist to: * Get rid of fossil fuels, nuclear waste, and the fake energycrises= energy from the vacuum. It has been supressed for decades, and there is proof of this! * Cure disases as AIDS, cancer, MS...

I know that some of the isotopes have extremely long half-lifes. However, isn't it true that generally speaking, a longer half life correlates to a lower rate of radioactivity? So wouldn't the most dangerous elements be those with short half-lifes? Isn't most of the danger from waste therefore...

I'd like to start a discussion/debate of nuclear power for the purpose of informing people about it. I am participating in a thread in another forum http://www.badastronomy.com/phpBB/viewtopic.php?t=9370 where we are discussing an article about Germany planning to phase out nuclear power. I...

Why do nuclear power plants raise the temperature of sea water? I can't find the answer to this anywhere on the internet.
