How much radioactive waste has been produced by US nuclear reactors stated in weight and volume?

As of 2021, the United States has produced approximately 90,000 metric tons of spent nuclear fuel, which is the primary form of radioactive waste from nuclear reactors. In terms of volume, this waste occupies about 1,000 cubic meters. Most of this spent fuel is stored on-site at nuclear power plants in pools or dry cask storage systems. The management and disposal of this waste remain ongoing challenges for the nuclear industry.
