Operational Mode 5 DESCRIPTION OF OCCURRENCE: | Operational Mode 5 DESCRIPTION OF OCCURRENCE: | ||
Due to crud buildup in a demineralizer used to process liquid active waste, the area around the demineralizer was a high radiation area of greater than 1000 mr/hr. At approximately 1740 hours, the last man tn leave the area did not lock the door. A Health Physics Technician found the door open at 1745 hours, notified his supervisor and was posted at the door to control access. At 1800 hours, the door was locked and the area secured. DESIGNATION OF APPARENT CAUSE OF OCCURRENCE: | Due to crud buildup in a demineralizer used to process liquid radio-active waste, the area around the demineralizer was a high radiation area of greater than 1000 mr/hr. At approximately 1740 hours, the last man tn leave the area did not lock the door. A Health Physics Technician found the door open at 1745 hours, notified his supervisor and was posted at the door to control access. At 1800 hours, the door was locked and the area secured. | ||
DESIGNATION OF APPARENT CAUSE OF OCCURRENCE: | |||
Since the demineralizer was not partitioned off with a locked door to that area, the entire radioactive waste area of the Auxiliary Building was designated a high radiation area. The cause of this occurrence was personnel error in that the last man to leave the area did not insure access control. The door to the radioactive waste area was to be secured with a chain and padlock. The padlock was closed and the man did not have the key. The area was left unguarded while he went to get the key from his supervisor. | Since the demineralizer was not partitioned off with a locked door to that area, the entire radioactive waste area of the Auxiliary Building was designated a high radiation area.
