I see where your going with this, and i too belive that nuclear energy is a safe source of energy. But even if we would upgread our generators, it still does not solve the real problem with nuclear energy, wich is how to store the used Uranium. Therefore I think the only solution is how we handle the final disposal of the used fule. When we figured out this problem, nuclear power will be the most efficient and safe energy source.

Part of the idea with new generations of nuclear power plants is that they should be both more efficient and safer for future generations. For example the “fourth-generation” reactors are believed to yield hundreds of times more energy out of the same amount of fuel as today's reactors. The waste should then only be needed to be kept sealed for a few hundred years, compared to the milleniums today. In addition, those are predicted to be able to use the waste that are being burried today.

Given that the nuclear power research continues, I am convinced waste won't be a problem within one hundred years.

Still, nuclear power will always be dangerous if not handled with care, but compared to energy production with coal and oil I think nuclear power is superior, as the climate change, in my opinion, is more urgent to prevent.

This is very interesting. As this technology progresses, do you think countries like Japan should use these reactors, or would be just as much at risk as they would be if they were using an older generation?
