CARLSBAD (AP) — Investigators trying to determine what caused a radiation release at the federal government’s underground nuclear waste repository in southern New Mexico have spotted melted plastic and rubber on some drums and boxes of waste.
They were able to take photographs of the melted material during their most recent trip into the Waste Isolation Pilot Plant near Carlsbad.
The plant’s recovery officials say the melted material indicates there was some kind of heat generated in the room where the waste is stored.
