The DOE (Department of Energy) operates several interim storage facilities for low- and intermediate-level waste and long-lived intermediate-level waste the Hanford site (Washington State). There are also decentralised storage facilities at 72 reactor sites in 33 states.
For low- and intermediate-level waste, there are both state-run (currently five facilities) and non-state-run disposal facilities (four closed, four in operation).
The Yucca Mountain site in a tuff formation was approved by Congress for disposal of high-level waste. However, the government has decided not to pursue this option and set up a commission to investigate alternative waste management strategies. The Blue Ribbon Commission on America's Nuclear Future submitted its final report at the beginning of 2012. It identifies deep geological disposal as the best strategy from a scientific viewpoint. A working group is now looking at the next steps to be taken in the programme.
There is a repository for military transuranic waste (WIPP) at Carlsbad (New Mexico).
