The denser the projectile, the harder the impact for a given size. DU is almost twice as dense as lead, making it highly suitable. The other metal used for anti-tank rounds is tungsten, which is also very hard and dense. When a tungsten rod strikes armour, it deforms and mushrooms, making it progressively blunter.

The heat released by fission is used to create steam that spins a turbine to generate electricity without the harmful byproducts emitted by fossil fuels.

Why does the U.S. not recycle nuclear waste?

The United States has eschewed reprocessing because of concerns about proliferation — that is, the risk that the material could be diverted for weapons — but other countries, such as France, do reprocess used fuel in civilian nuclear reactors. Recently, fresh interest in this option has emerged in the States.

That's right! Spent nuclear fuel can be recycled to make new fuel and byproducts. More than 90% of its potential energy still remains in the fuel, even after five years of operation in a reactor. The United States does not currently recycle spent nuclear fuel but foreign countries, such as France, do.
