Default Safe Nuclear Power? Hydrogen byproduct? Sound cool?

The retired founder of Green-peace says we need to go Nuclear to save us from Global warming.

With safe nuclear power, would we no longer need to compete for foreign oil? Could we dramatically reduce our green house gas output if we embrace it? Would this stop our indirect and unintended financial support that filters down to the international terrorists? These sound like good things to me if we can rely on safe nuclear power.

All of our electrical needs, witch could include heating, cooling and hydrogen for hydrogen hybrid cars may be able to be provided by safe nuclear power of the type discussed in the second link below with out any green house gas production. Sound good?

The French get about 75% of their electricity from Nuclear power and the Germans are not far behind. Could we follow their lead?

When I saw the first Democrat debate of this political season, the moderator asked all of the candidates if they would rule out further expansion of nuclear power as an alliterative energy source. Not one said they would rule it out. I was shocked. I thought at least a few would take the opportunity to gain favor with those who fear nuclear power. A few said ok only if we can make it safer and find a safer way to dispose of the related dangerous wast.

These two links have very interesting articles in favor of nuclear power to save us from global warning now.

Green peace founder promotes nuclear power as a way to save us from Global Warming.

What about the nuclear waste? That's still the biggest concern isn't it?

The storing of waste which has a ten thousand year of radioactive life has been the big scare tactic no, no, in the states for years. I wonder how many folks saw the PBS presentation several months ago with visits to several French nuclear operating plants. They had been in operation for over twenty years and all the waste of this time was stored in "cisterns" imbedded in the floors of just "one" storage room about 100ft by 100 ft.
The Plymouth nuclear plant about 19 miles from my home has been storing waste in containers ready for shipping to "Yucca Flat" for the past fifteen years. It can be shipped in just two railroad cars. The waste is a non-factor every where else in the world. (because, relatively, there is so little of it.)
John Edwards, one of the last candidates to drop out of the running for the democratic nomination stated during one debate that one of the first things he would do as President would see about closing down all present operating nuclear plants in the U.S. (Go figure!)

Absolutely, that is a very valid concern. What to do with it the nuclear waste will continue to be a hotly debated issue.

But remember, we are breathing the waste product from fossil fuel right now. And it is the couse of global warming. Nuclear power dose not couse global warming.

The quote below is from my second link in the first post in this string about the safety of the new nuclear power technology.

This is the link again
http://www.physorg.com/news8956.html

" Physicistsand engineers at Beijing's Tsinghua University have made the first great leap forward in a quarter century, building a new nuclear power facility: a pebble-bed reactor (PBR) – sometimes also known as a Pebble Bed Modular Reactor (PBMR). This reactor is small enough to be assembled from mass-produced parts and cheap enough for emerging economies. Its safety is a matter of physics, not operator skill or reinforced concrete. This reactor is meltdown-proof.

What makes it so safe is the fuel: instead of conventional fuel rods made of enriched uranium, PBRs use small, pyrolytic graphite coated pebbles with uranium cores. As a PBR reactor gets hotter, the rapid motion of atoms in the fuel decreases probability of neutron capture by U-235 atoms. This effect is known as Doppler Broadening. Nuclei of heated uranium move more rapidly in random directions generating a wider range of neutron speeds. U-238, the isotope which makes up most of the uranium in the reactor, is much more likely to absorb the faster moving neutrons. This reduces the number of neutrons available to spark U-235 fission. This, in turn, lowers heat output. This built-in negative feedback places a temperature limit on the fuel without operator intervention.

PBRs use high-pressure helium gas, not water, for cooling. Reactors have been “run dry” – without cooling gas. Result: they simply stabilize at a given temperature – lower than the pebbles’ shell melting point. No meltdown can occur.


PBR from http://www.pbmr.co.za
South Africa may have the most modern PBR on the drawing board. With the help of German scientists – acknowledged leaders in the field - they have planned to build several reactors within the next five years. Images in this article come from their design."

A second quote for the same site:
"The high-temperature gas design also has a silver lining – it can produce hydrogen. Think about that – fuel cell vehicles need expensive-to-produce hydrogen to run on – this reactor could make hydrogen as a byproduct.

Generation of hydrogen has been the biggest stumbling block to it adoption as a clean fuel. Hydrogen, found primarily in water, is expensive to extract as a gas. While the technical problems of handling, storage and use as fuel are largely solved, the high energy cost to produce hydrogen has made it an energy transport medium, not a source.

These new reactors run at high temperatures which are perfect for cracking abundant water or helium gas into hydrogen which can then be used as a green fuel – burning hydrogen just produces water vapor.

PBRs could produce cheap hydrogen that could be piped to areas of need or used in the local communities."

Now you have to ask yourself. Who would be hit most by the adaption of this clean new technology?
Do you ever suppose that the richest investors in the world would back anything other than the oil industry?

The oil companies are not majority owned by a bunch of fat old cigar smoking white guys. The are mostly owned by pension funds. If we punish the oil companies and reduce their stock performance, it will be the regular guys and gal that we be most hurt when their pension funds shrink.

Alliteratively, those same funds could just as easily invest in the nuclear industry. Those funds will alway fallow the best stock performance they can find in a diversified portfolio.

NO,, unfortuneatly it was the Carter administration in 1985 our own NRC in Idaho worked the entire thing out the same month it was orderd closed down by Carter all other countrys including Iran now use this type of reactor to cut down on waste, reuseing the fuel many times where our recators only use it once then store the partly used fuel forever. Or we can just keep burning coal and natural gas.... I know which we'll run out of first.

We had a cool engineer that always came to check the cars all the time. One day we asked how much power they made. A couple days later he came back and showed us.
