"The U.S. government said it will stop issuing permits for new nuclear power plants and license extensions for existing facilities until it resolves issues around storing radioactive waste. The government's main watchdog, the Nuclear Regulatory Commission, believes that current storage plans are safe and achievable. But a federal court said that the NRC didn't detail what the environmental consequences would be if the agency is wrong."
The NRC says that "We are now considering all available options for resolving the waste issue, But, in recognition of our duties under the law, we will not issue [reactor] licenses until the court's remand is appropriately addressed."
Affected are 14 reactors awaiting license renewals, and an additional 16 reactors awaiting permits for new construction.
