24 HOUR REPORT - VALID SAFETY SYSTEM ALARM
"ON 11/19/99 AT 1600, X-326 CASCADE BUILDING OPERATIONS RECEIVED A SMOKE HEAD ALARM ACTUATION AT THE ERP 1A WITHDRAWAL STATION DURING A CYLINDER CONNECTION EVOLUTION. WHILE CONNECTING THE PIGTAIL TO THE CYLINDER, A SLIGHT WISP OF UF6 SMOKE APPEARED BETWEEN THE PIGTAIL AND THE MANIFOLD SAFETY VALVE. EMERGENCY RESPONSE PERSONNEL RESPONDED AND MONITORED THE AREA. ALL AIR SAMPLE RESULTS FOR HYDROGEN FLUORIDE AND UF6 WERE BELOW DETECTABLE LEVELS. THIS EVENT IS REPORTABLE DUE TO THE VALID ACTUATION OF A "Q" SAFETY SYSTEM. THERE WAS NO LOSS OF HAZARDOUS/RADIOACTIVE MATERIAL OR RADIOACTIVE/RADIOLOGICAL CONTAMINATION EXPOSURE AS A RESULT OF THIS EVENT."
THE LICENSEE NOTIFIED THE NRC RESIDENT INSPECTOR AND THE DOE SITE REPRESENTATIVE.
* * * UPDATE AT 1600 ON 12/09/99 BY ERIC SPATH TO JOLLIFFE * * *
PORTSMOUTH PERSONNEL DESIRE TO RETRACT THIS EVENT BASED ON THE DETERMINATION THAT THE ACTUAL PLANT CONDITIONS WHICH THE SAFETY SYSTEM IS DESIGNED TO PROTECT AGAINST DID NOT EXIST. THE 1A WITHDRAWAL POSITION PIGTAIL WAS ISOLATED FROM THE LIQUID UF6 SYSTEM BY A CLOSED MANIFOLD VALVE AND NO LIQUID UF6 WAS INVOLVED IN THE OUT GASSING. A WITHDRAWAL WAS TAKING PLACE AT THE ADJACENT 1B POSITION, WHICH SHARES THE SAME COMPRESSORS, PIPING, AND ACCUMULATOR, BUT THE LEAK WAS NOT ASSOCIATED WITH THIS POSITION. THE TECH SPEC REQUIREMENT BASIS STATEMENT INDICATES THAT THE PURPOSE OF THE PIGTAIL LINE ISOLATION SYSTEM IS TO MINIMIZE A RELEASE OF LIQUID UF6 DUE TO A PIGTAIL FAILURE DURING A WITHDRAWAL. SINCE THE PIGTAIL WAS ISOLATED FROM THE LIQUID UF6 SYSTEM WHILE THE CYLINDER WAS BEING CONNECTED, THE PIGTAIL LINE ISOLATION SYSTEM SAFETY FUNCTION WAS NOT REQUIRED.
PORTSMOUTH PERSONNEL NOTIFIED THE NRC RESIDENT INSPECTOR. THE NRC OPERATIONS OFFICER NOTIFIED THE R3DO PAT HILAND AND THE NMSS EO TED SHERR.

AGREEMENT STATE REPORT - POSSIBLE DAMAGED TROXLER GAUGE
On 11/19/99 at about 0700 CST, a Mississippi Department of Transportation (DOT) truck was involved in an accident. The truck was carrying a Troxler Model 4640B Moisture Density Gauge in a locked and chained Type-2 container. The container broke free of the chain but remained in the truck during the accident. There was no apparent damage to the gauge. The Mississippi Department of Health was contacted at about 0800 CST about the accident. They recommended that the gauge be leak tested, and DOT is sending the gauge to Troxler for testing.
The Mississippi Department of Health contacted NRC Region 2 (Richard Woodruff) and discussed this incident with them.
