Spent Nuclear Fuel: Is Off-Site Storage Now Off the Agenda?
The Nuclear Regulatory Commission’s recent “waste confidence” ruling, which declares storage of spent fuel at reactor sites safe indefinitely, could fundamentally undercut the decades-long U.S. policy of seeking an off-site, permanent burial site for high-level nuclear waste. A five-decades-old goal of the U.S. nuclear power industry, its regulators, and the Department of Energy (DOE)—permanent, off-site […]
