Original Godzilla In U.S. Theaters
saudadelinux writes "The original Gojira is in theaters now through July. See the *uncut Japanese version* of the film as it was really meant to be seen, as a serious anti-nuke picture, not just Saturday afternoon UHF fodder."
Correct. Additionally, fast breeder reactors, or breeder-burners achieve excellent efficiency. They start with Uranium-235, but in the process of using it, they "breed" Plutonium-239, which they can then turn around and use for additional fuel.
The reason these reactors are not in widespread usage is political, not technical. Governments (i.e. the U.S., China, France, UK, and Russia) don't want a lot of plutonium being created in commercial reactors because of its potential use as a weapon.
Yes, U-235 can be used in a weapon, but "weapons-grade" uranium must be enriched to ~90% U-235. Commercial reactors can run with a much lower enrichment percentage, which makes governments less nervous.
