Development of Metal Recycling Process from Decommissioned Nuclear Power Plants

Dismantling and demolition of a nuclear power plant generates a large amount of metal waste. Recycling of such waste for resource is important because of the limited capacity of the disposal site. Authors have developed metal recycling processes. It is found that pyrometallurgical separation techniques can effectively separate nickel and cobalt, which contain main contributors of radioactivity, from iron and chromium.
