24-HOUR REPORT REGARDING ACTIVATION OF SMOKE HEADS
"At approximately 1220 hours on 12/30/00, a process operator was conducting weekly valve status checks on the cell floor above the extended range products station when three CADP smoke heads alarmed. The operator did see a visible haze and smell HF as he immediately left the area. 'See and flee' emergency procedures were immediately implemented. The affected ERP withdrawal station was in an applicable TSR mode (withdrawal) at the time of the alarm. Results of all surveys performed for airborne HF and radiation were less than MDA. At 1324 hours an 'all clear' was granted on emergency response. PORTS is reporting this alarm as a valid actuation of a 'Q' safety system, which is the CADP smokehead."
The NRC resident inspector has been informed of this event.
