thhe only reason they havent been built yet is because there hasnt been the investment into them.
back in the begining of nuclear power there was the cold war and the need for plutonium for nuclear bombs. the boiling water reators that we're stuck with now were the easiest way to produce that material..
now those reactors not only have the problem of leaving long lasting waste but they also are prone to melting down if the cooling pumps fail.
now for decades whenever there was a new reactor built it was suggested to build the newer safer designs but because we were stuck with the cold war era plants and it was cheaper to just copy the old designs and add patches to it we stayed stuck with them.
to call them "experimental" or "developmental" doesnt really give justice to the situation...
i think you'll find any solution to agw will take a long time... covering an area equivilent to arizona with concentrating solar panels isnt gong to happen over night... or covering an area the size of california with wind turbines..
there is no perfect solution at all but nuclear is a very small very condensed solution with minimal waste and impact.
and for all those idiots who keep referencing fukishima
- one of the worlds oldest reactors
- hit by an earthquake that moved the whole island of japan 8 feet
- hit by a tsunami
- the reactor building and reactor survived that
- fooded water pumps/generators in basement caused the over heating
- the tsunami killed 10's of thousands of people yet fukishima killed none
- people still live next to the sea
there is no
