FAQ: Recycling Nuclear Waste

Instead of storing spent nuclear fuel in dry casks in a once-through fuel cycle, another option is to reprocess the used fuel. This is called the "twice-through" or the "closed" nuclear fuel cycle. Although the terms are often used interchangeably, "reprocessing" specifically refers to separating plutonium and uranium from spent fuel contrast, "recycling" means using
