Last month’s false alarm at Y-12’s Purification Facility occurred only a week after the facility had been restarted following a months-long shutdown (due to a leak of acetonitrile). According to info from federal spokesman Steven Wyatt, the restart took place on March 18, eight days before the March 26 false alarm. While the false alarm was disturbing, coming so soon after the prior problem, things returned to normal soon after the precautionary evacuation. “Operations were immediately resumed after the false alarm last month,” Wyatt said.
The Purification Facility is used for production of Fogbank, a classified material in some nuclear weapons (including the W76 warhead).
