The U.S. Department of Energy is now targeting 2048 as the deadline for opening a permanent underground disposal site for nuclear waste. There is currently about 68,000 metric tons of waste at commercial reactors sites. The new program calls for a temporary above-ground site for about 3,600 metric tons of waste by 2021 and a larger facility for 20,000 metric tons by 2025. Exactly where the final facility will be built is far from being decided, with some groups pushing the Obama administration to reconsider Yucca Mountain. A permanent Yucca Mountain facility was once planned for 2020, but that proposal has since been scrapped.
