Nuclear reactors use and produce materials that are carefully regulated. Special nuclear materials include uranium-233, uranium-235, enriched uranium, and plutonium. Source materials include natural uranium, thorium, and depleted uranium that cannot be used as reactor fuel. By-product material is generated from nuclear materials these by-products include any radioactive material or waste products produced by the reactor system. In 2004, there were approximately 104 nuclear facilities in the United States the majority of these systems are located in states east of the Mississippi River. Only 19 nuclear reactors are operated west of the Mississippi.
