The Trump administration is planning to reclassify high-level radioactive waste as low-risk, in a bid to cut as much as $40 billion from cleanup costs at nuclear weapons production sites around the U.S. A top Energy Department official called the proposal a “responsible, results-driven solution” to the problem of nuclear waste disposal. The move was condemned by environmentalists and scientists who say the waste needs to be contained in facilities deep underground. In a statement, the Natural Resources Defense Council said, “The Trump administration is moving to fundamentally alter more than 50 years of national consensus on how the most toxic and radioactive waste in the world is managed and ultimately disposed of.”
