Event Text
POTENTIALLY TOXIC ATMOSPHERE IN AN ACCESS FACILITY
"At 1315 hours personnel performing repairs to an air conditioning system inside the Access Facility (AF) reported a Freon leak from a valve packing failure. All personnel were evacuated from the building. Radiation protection personnel entered the building and atmospheric sampling commenced. Sample results indicated a potentially toxic atmosphere in portions of the AF, and at 1330 hours an Emergency Plan Unusual Event was declared on EAL HU7, ’Hazards and Other Conditions Affecting Plant Security.’
"The AF was locked down and plant access and egress have been halted pending the restoration of AF atmosphere. Required security compensatory measures are in place.
"The Freon completely discharged from the affected air conditioner through the leak. Actions to establish a habitable atmosphere inside the AF continue.
"Units 1 and 2 are unaffected by this event and continue to operate at full power."
The licensee notified the NRC Resident Inspector.
