Description/Abstract:
A basket of enriched uranium machine turnings ignited and burned in a new scrap-recycle process at the Oak Ridge Y-12 Plant. Such events, involving both depleted and enriched uranium, although not desirable, are not totally unexpected. However, in this instance the chemical operator lowered the basket of burning chips back into a tank of Freon 113, from which it had shortly before been removed. This action resulted in quantities of uranium chips, uranium oxide, and Freon 113 being violently discharged out of the basket and onto the floor. Freon 113 was vaporized and pyrolized by the high-temperature uranium metal, with dispersion of significant quantities of vapor and smoke. Interim action were taken, prior to restart of chip-cleaning operations, to minimize the potential for future chip fires.
