Incident Narrative
THE RELEASE ORIGINATED FROM A FAILED O-RING ON A HAMMER UNION FITTING LOCATED ON THE FILTRATION SYSTEM. IMMEDIATELY PRECEDING THE RELEASE, THE FACILITY EXPERIENCED A POWER FAILURE. THE POWER FAILURE CAUSED THE ""ACTIVE LINEUP"" STATUS TO BE REMOVED IN THE PLC. WHEN POWER WAS RESTORED, PLC PROGRAMMING CAUSED TWO STATION VALVES TO CLOSE DOWNSTREAM OF THE FILTER SYSTEM. PRESSURE TRANSMITTERS DID NOT RECORD AN EXCEEDANCE OF MOP. SOIL FROM THE RELEASE AREA WAS REMEDIATED. THE O-RING IN THE HAMMER UNION WAS REPLACED AND THE SYSTEM WAS HYDROTESTED PRIOR TO RETURNING TO SERVICE. FOLLOWING THE RELEASE, PLC PROGRAMMING WAS MODIFIED TO PREVENT THE VALVES FROM CLOSING WHEN AN ""ACTIVE LINEUP"" STATUS IS REMOVED DURING A POWER OUTAGE. SUPPLEMENTAL SUBMITTED TO REMOVE NRC NUMBER AS NO REPORT WAS REQUIRED. SECOND SUPPLEMENTAL SUBMITTED TO ADD THIS EXPLANATION TO WHAT WAS CHANGED ON FIRST SUPPLEMENTAL.
