What are the uses of Uranium and Plutonium besides nuclear weapons?

URANIUM : The major application of uranium in the military sector is in high-density penetrators. This ammunition consists of depleted uranium (DU) alloyed with 1?2% other elements. At high impact speed, the density, hardness, and pyrophoricity of the projectile enable destruction of heavily armored targets. Tank armor and other removable vehicle armor are also hardened with depleted uranium plates.
Depleted uranium is also used as a shielding material in some containers used to store and transport radioactive materials. While the metal itself is radioactive, its high density makes it more effective than lead in halting radiation from strong sources such as radium.
Uranium was also used in photographic chemicals in lamp filaments, to improve the appearance of dentures, and in the leather and wood industries for stains and dyes.
Uranium salts are mordants of silk or wool. Uranyl acetate and uranyl formate are used as electron-dense "stains" in transmission electron microscopy, to increase the contrast of biological specimens in ultrathin sections and in negative staining of viruses, isolated cell organelles and macromolecules.

PLUTONIUM - The isotope plutonium-239 is a key fissile component in nuclear weapons, due to its ease of fission and availability.
Plutonium-238 has also been used successfully to power artificial heart pacemakers, to reduce the risk of repeated surgery.Plutonium-238 was studied as way to provide supplemental heat to scuba diving. Plutonium-238 mixed with beryllium is used to generate neutrons for research purposes.
