Nuclear Waste Itself

In the United States there are two types of radioactive waste produced at nuclear reactors: low-level waste (LLW) and high-level waste (HLW). While low-level nuclear waste represents most of the waste volume, high-level waste represents most of the radioactivity. For this reason HLW presents the major problem.

High-level waste in the United States (and also Sweden and Finland) comprises the used nuclear fuel elements, called spent fuel. In France, Great Britain, and Japan, where fuel is reprocessed to remove unused uranium fuel and plutonium (which represents 95 percent of the material in spent fuel), HLW primarily includes fission products and long-lived radioactive materials called actinides. (Russia and China are developing reprocessing capability, and Germany, the Netherlands, Switzerland, and Belgium reprocess their spent fuel elsewhere.) These are incorporated into radiation-resistant glass to produce blocks that can be placed into a temporary storage facility or a permanent underground...
