Radioactive materials at the end of a useful life cycle that should be
properly disposed of, including--
- The highly radioactive material resulting from the reprocessing of spent
nuclear fuel, including liquid waste directly in reprocessing and any solid
material derived from such liquid waste that contains fission products in
- Irradiated reactor fuel; and
- Other highly radioactive material that the Commission, consistent with
existing law, determines by rule require permanent isolation.
High-level waste (HLW) is primarily in the form of spent fuel discharged
from commercial nuclear power reactors. It also includes HLW from activities
and a small quantity of reprocessed commercial HLW.
