Nuclear Waste
High-Level Radioactive
Waste (HLRW)
- High-level waste from nuclear power plants is
the spent, or used, uranium fuel.
- Amount of used nuclear fuel generated per year
presently stored at plants throughout the nation:
20 metric tons per year is
generated by a typical plant; 2,000 metric tons is
generated by the nuclear industry per year. The entire
industry has produced about 40,000 metric tons of used
nuclear fuel over the past four decades. If used fuel
assemblies were stacked end-to-end and side-by-side, this
would cover a football field about four yards
deep.
Low-Level Radioactive Waste (LLRW)
- Low-level waste consists of items that have
come in contact with radioactive materials, such as gloves,
personal protective clothing, tools, water purification
filters and resins, plant hardware, and wastes from reactor
cooling-water cleanup systems. It generally has levels of
radioactivity that decay to background radioactivity levels
in under 500 years. About 95 percent decays to background
levels within 100 years or less.
- Amount of low-level radioactive waste
generated per year by plant/industry:
- 1998 Average Reactor Volume - 742
cubic feet (21 cubic meters) for PWRs; 2,790 cubic feet
(79 cubic meters) for BWRs
- 1998 Industry Volume - 135,394.71
cubic feet (3,834 cubic meters)
- The amount of low-level radioactive
waste volume going to disposal facilities, such as
Barnwell, has been reduced 96 percent since 1980. There is
a downward trend in the volume of LLRW generated as well.
- As of June 2000, South Carolina will
have received about $300 million, $235 per cubic feet, in
taxes on low-level nuclear waste disposed of at
Barnwell.
- LLRW disposal facilities:
- Barnwell, S.C.
- Hanford, Wash.
- Envirocare, Utah
