The idea of storing radioactive nuclear waste inside a hollowed-out salt cavern might look good on paper. The concept is to carve out the insides of the caverns, deep underground, then carefully move in the waste. Over time, the logic goes, the salt will move in and insulate the containers for thousands of generations.
“The whole game is to engineer something that can contain those contaminants on the order of tens of thousands of years,” Tim Judson, the executive director of the Nuclear Information Resource Service (NIRS), told Truthout. NIRS is intended to be a national information and networking center for citizens and environmental activists concerned about nuclear power, radioactive waste, radiation and sustainable energy issues, according to Judson.
Salt-cavern storage was the plan for the Waste Isolation Pilot Project (WIPP), the world’s third-deepest geological repository, constructed and licensed to permanently dispose of radioactive waste for 10,000 years. The repository sits approximately 26 miles east of the town of Carlsbad in southeastern New Mexico.
