China has come up with a new nuclear technology called "pebble bed technology".
Essentially power plants built with this technology could only do one thing
if something went wrong and that would be to shut down. It would be impossible
for these reactors to explode or melt down. The idea is rather simple. Balls
of Uranium power these reactors and each ball of uranium is wrapped in an incredibly
strong layer of silicon carbide. These spheres have a much higher melting point
then the temperature inside the reactor could ever reach. So essentially it
would be impossible for the reactor to meltdown or explode. This technology
is in the test phase but if it works out as envisioned China will leap frog
ahead of the US in this area and then one wonders if they would not export
this technology to countries that could help them meet their energy needs.
One such country is Iran; in 2003 Iran alone supplied China with over 14% of
its oil needs. This figure is definitely substantially higher today. China
is desperate for energy and they openly admit to this; when one is desperate
for something one is willing to trade almost anything.
"We need every type of energy," says Zhang Zuoyi, head of the institute
that helps run the pebblebed test reactor. "We are hungry." China's leaders
won't listen to naysayers. They can't afford to.
Another point of interest is that China is about to embark on the biggest
nuclear power building plant spree ever undertaken by any nation. Their goal
is to derive roughly 4-5% of their Energy needs from Nuclear Power in the next
15 years. While this might sound small when compared to other nations this
simple plan means that China will need to build roughly 45 nuclear plants in
15 years or about 3 plants every year. Imagine what effect this will have on
uranium prices. Off course in the next few years they could come out with even
better technology, which might mean even more nuclear plants. Right now the
limiting factor is that no one has thought of coming up with a nuclear power
plant assembly line. We are positive that one nation will adopt this idea and
when they do installing a new plant will be something that takes months instead
of years.
China's new pebble bed technology might be one of the reasons India is not
too worried about the nuclear deal falling through with the United States.
Not only is this technology superior but also it will most likely cost a lot
less and they will not be pushed into a position of having to forcefully take
a stance against Iran. Increasingly it appears that more nations are willing
to stand up to the US and as the saying goes there is strength in numbers.
China is positioned to leapfrog the world in nuclear power precisely because
it entered the race late. Until now, the country has built a hodgepodge of
reactors with different technologies and safety features. But recently top
leaders decided to build a newer infrastructure virtually from scratch based
on the most advanced, and safest, technologies. Although the pebble-bed reactor
is not yet ready for prime time, the government is buying equipment and designs
that have never been built before. China plans to choose one design of three
submitted by Areva of France, Atomstroy export of Russia and Westinghouse Electric
for an $8 billion program to build reactors in the eastern province of Zhejiang.
(Some industry experts say Areva will probably win, especially since the Chinese
government may bristle at the recent takeover bid by Japan's Toshiba on Westinghouse.)
The Chinese plan to work closely with the winner to learn how to design and
operate the reactors. The goal is to use this technology as the basis for subsequent
Chinese plants.
The most likely technology to export, of course, is the pebble bed reactor.
All reactors, including the pebble bed, use uranium fuel to produce heat that
is used to turn electrical turbines. In conventional so-called light-water
reactors, the heat is generated by thousands of fixed metallic rods, which
require elaborate cooling systems to keep them from overheating and backup
cooling systems in case the primary ones fail. Furthermore, a conventional
reactor must be housed in a concrete containment vessel to mitigate damage
in case it overheats. In the pebble bed reactor, thousands of tennis-ball-size
spheres coated in layers of silicon carbide, ceramic material and graphite
each contain thousands of granules of the fuel, uranium dioxide. Because the
pebbles dissipate heat so efficiently, say the designers, the fuel inside them
couldn't possibly get hot enough to penetrate the graphite casing. The pebble-bed
reactor, in fact, doesn't even have a containment vessel. Another advantage
of pebble beds is that it's easier to make small plants and put them up quickly,
which lends itself to China's plan of spreading plants around the hinterlands.
Extracting fuel from pebble bed reactors to use for weapons would be difficult
and expensive. Full

Conclusion
Even Ukraine which had renounced nuclear technology has decided that they
need to build at least 15 plants over the next decade to prevent a repeat of
the recent energy crisis when Russia cut of gas supplies to Ukraine. Almost
every nation is slowly but surely embracing nuclear energy something that was
once shunned. While we have many nations focussing on developing new technologies
for nuclear power plants no one is spending the time and money needed to find
new supplies of uranium and open up new mines. Current demand far outstrips
the available supply and one can only imagine the uranium crunch that will
be created in years to come unless a massive program to open up new mines and
find new supplies of uranium is undertaken shortly. As usual a crisis that
could have easily been prevented will be allowed to develop into a full blown
disaster before something meaningful is done. The reasons are always the same;
key big players are going to make fortune and the expense and misery of others.
When the choice comes to down to money or doing the right thing 9 out of 10
times money wins. Hence make sure that you own the right companies and buy
them at the right time as they are many useless so called uranium companies
out there. One can also buy a great company at the wrong time. In order to
win one has to buy at the right time and also sell at the right time.
