| VALID ACTUATION OF A 'Q' SAFETY SYSTEM - 24 HOUR REPORT |
| |
| "At 0115 hrs, on 04/12/99, Operations Personnel in the X-344 facility, |
| received a steam shutdown alarm on Autoclave #2 during a cylinder heating |
| (Mode II). The steam shutdown was caused by the actuation of the High |
| Condensate Level Shutoff System ('Q' system). Investigation of the alarm |
| and completion of 'as found' testing gave indication that the alarm was |
| caused by an actual high condensate level condition, which cleared after the |
| steam shutdown occurred. The cylinder in this autoclave was disconnected and |
| the autoclave was declared 'inoperable' by the Plant Shift Superintendent. |
| Testing of the High Condensate Level Shutoff System will be performed by |
| Maintenance and Engineering personnel. Autoclave #2 will remain |
| out-of-service pending an Engineering Evaluation and Resolution of the alarm |
| condition." |
| |
| Portsmouth personnel notified the NRC Resident Inspector and the onsite DOE |
| representative. |

| RADIATION DEVICE CONTAINING 1 CURIE OF AMERICIUM POSSIBLY STOLEN |
| |
| Arvan Industries of Greenwood, Indiana contacted the Payne Firm (Dan Woody |
| acting as representative) late Friday, 4/9/99, for consultation concerning a |
| radiation device containing 1 Ci of Am-241 that is believed stolen. The |
| device is missing from the Arvan Exhaust Greenwood Facility located at 101 |
| Center St., Greenwood, Indiana during ongoing closure activities. The |
| device weighs about 200 pounds, contains a sealed source of 1 Ci of Am-241, |
| and was used to measure the thickness of rolled steel. The device, an Xact |
| Ray Thickness Gauge 3500 Model, serial #48761-1 and source serial #2786LX |
| was manufactured by the Loral Control Systems of Archbald, Pennsylvania. |
| The manufacturer is no longer in business. |
| |
| There is an ongoing investigation and a written report will be submitted |
| later. |
| |
| The police have not been contacted at this time. It will probably be |
| reported to the Greenwood, Indiana police of possibly the Indian Highway |
| police. |

| SCRAM PILOT AIR HEADER INADVERTENTLY ISOLATED WHICH RESULTED IN A REACTOR |
| SCRAM. NO CONTROL ROD MOVEMENT BECAUSE ALL CONTROL RODS WERE ALREADY FULLY |
| INSERTED. |
| |
| The licensee received a full Reactor Protection System actuation from Scram |
| Discharge Volume High Water Level. No control rod movement due to the fact |
| that all the control rods were already fully inserted into the core. The |
| licensee was performing a clearance to perform work on an air valve |
| associated with the Main Steam Isolation Valves. The Scram Pilot air header |
| was inadvertently isolated when the air line going to the Main Steam |
| Isolation Valves was isolated. |
| |
| The work involved a valve on the air supply line to the outboard MSIVs. The |
| P&ID was inadequate because it was not evident that the isolation valve used |
| also isolated the scram pilot air header. |
| |
| The NRC Resident Inspector was notified of this event by the licensee. |

| |
| THE EMERGENCY SERVICE WATER WAS LOST AS A RESULT OF THE FAILURE OF #13 |
| EMERGENCY SERVICE WATER PUMP TO START, WHICH PUT HPCI OUT OF SERVICE AND |
| THE PLANT IN A 24 HR TO SHUTDOWN LCO ACTION STATEMENT. WHEN THEY ATTEMPTED |
| TO START #13 EMERGENCY SERVICE WATER PUMP, THE MOTOR WOULD HUM BUT THE |
| IMPELLER WOULD NOT TURN AND THAT RESULTED IN THE TRIP OF THE PUMP BREAKER. |
| THEY MANUALLY TRIED TO TURN THE IMPELLER , WHICH SEEMED STUCK INITIALLY, BUT |
| THEY FINALLY GOT IT TO TURN FREELY. THERE MAY HAVE BEEN SOME TYPE OF |
| DEBRIS THAT WAS CAUSING THE IMPELLER NOT TO TURN. CURRENTLY THEY ARE |
| PERFORMING OPERABILITY CHECKS ON THE PUMP SO THAT THE LCO CAN BE EXITED. |
| DURING THIS EVENT THE NORMAL SERVICE WATER WAS AVAILABLE. |

| THIS PART 21 IS CONCERNED WITH A POTENTIAL DEFECT IN A COMPONENT ON THE |
| DSRV-16-4 ENTERPRISE DIESEL GENERATOR SYSTEM. THE POTENTIAL PROBLEM IS WITH |
| A CONNECTING ROD ASSEMBLIES BUILT SINCE SEPT 1986 THAT USE OR HAVE BEEN |
| CONVERTED TO USE PRESTRESSED FASTENERS TO ATTACH THE ROD BOX TO THE MASTER |
| ROD. THESE NEW ROD ASSEMBLIES (P/N 1A-7802) COME ASSEMBLED WITH PRESTRESSED |
| FASTENERS THAT ARE SUSPECTED TO BE OF INCORRECT LENGTH. THE PLANTS INVOLVED |
| ARE VOGTLE (ENGINE S/N 76021-4) AND PERRY (ENGINE S/N 75051-2). |
| |
| IN ADDITION, UTILITIES WITH DSRV-4 ENGINES WHO HAVE PURCHASED REPLACEMENT |
| P/N 1A-6280 OR 1A-6281 CONNECTING ROD ASSEMBLIES (WITH BOLTS) SINCE SEPT., |
| 1986 AND HAVE SUBSEQUENTLY CONVERTED THESE TO PRESTRESSED FASTENERS (OR |
| PLANNING TO CONVERT) COULD ALSO BE AFFECTED. THE FOLLOWING SITES MAY BE |
| AFFECTED GRAND GULF (ENGINE S/N 74033-6), HARRIS (ENGINE S/N 74046-9), |
| CATAWBA (ENGINE S/N 75017-20), PERRY (ENGINE S/N 75051-4), COMANCHE PEAK |

| TWO CONTAINMENT ISOLATION VALVES ON SAME PENETRATION DECLARED INOPERABLE |
| PLACING PLANT IN 3.0.3 LCO ACTION STATEMENT. |
| |
| THE INBOARD AND OUTBOARD CONTAINMENT ISOLATION VALVES ON THE GLYCOL SYSTEM |
| WERE DECLARED INOPERABLE. THIS CONDITION OCCURRED DURING A TAGGING ACTIVITY |
| FOR MAINTENANCE. IT WAS NOTICED THAT THE RED AND GREEN LIGHTS FOR THESE |
| VALVES WERE BOTH ON. ENTERING 3.0.3 GIVES THEM ONE HOUR TO REPAIR AND 6 |
| HOURS TO BE IN HOT S/B. THEY ARE CURRENTLY TROUBLESHOOTING AND COMMENCING |
| REPAIR. THEY ONLY NEED TO RETURN ONE OF THE VALVES TO OPERABLE CONDITION SO |
| THAT IT CAN BE ISOLATED WOULD ALLOW THEM TO EXIT 3.0.3. THE BASIS FOR BEING |
| OUTSIDE THE DESIGN BASIS IS THAT THEY HAVE A PENETRATION WHICH CAN NOT BE |
| ISOLATED. |
| |
| THE RESIDENT INSPECTOR WILL BE NOTIFIED. |

| *** UPDATE ON 4/12/99 @ 1756 BY SIMONS TO GOULD *** RETRACTION |

| FACTS UNIT 2 WAS NEVER OUTSIDE DESIGN BASIS. UPON FURTHER REVIEW, ENTRY IN |

| THE PLANT HAD AN AUTOMATIC ACTUATION OF THE UNITS 1 & 2 CONTROL ROOM |
| EMERGENCY AIR RECIRCULATION FAN (VSF-9). |
| |
| THE ACTUATION OF VSF-9 WAS DUE TO EXCEEDING THE ACTUATION SETPOINT OF 154 |
| CPM FOR THE UNIT 1 CONTROL ROOM SUPPLY VENTILATION RADIATION MONITOR |
| (2RITS-8001A). THE EVOLUTION WHICH CAUSED THE BACKGROUND RADIATION LEVELS |
| TO EXCEED THE RADIATION MONITOR SETPOINT WAS TRANSPORTING A MULTI-ASSEMBLY |
| SEALED BASKET (MSB) CONTAINED IN THE MSB TRANSFER CASK (MTC) FROM THE SPENT |
| FUEL POOL AREA (ELEV 404) TO THE RAILROAD BAY (ELEV 354). PRIOR TO |
| COMMENCING THIS EVOLUTION, THE CONTROL ROOM VENTILATION SUPPLY WAS ISOLATED |
| AND IN RECIRCULATION MODE USING 2VSF-9 (UNIT 2 CONTROL ROOM EMERGENCY AIR |
| RECIRCULATION FAN). UNITS 1 AND 2 SHARE A COMMON VENTILATION SYSTEM. THE |
| 2RITS-8001A IS LOCATED OUTSIDE OF THE CONTROL ROOM, ADJACENT TO THE SPENT |
| FUEL POOL AREA. THE MOVEMENT OF THE MTC NEAR 2RITS-8001A RESULTED IN |
| INCREASED BACKGROUND RADIATION LEVELS ABOVE THE RADIATION MONITOR ACTUATION |
| SETPOINT. HOWEVER, THERE WAS NO INCREASE IN THE CONTROL ROOM VENTILATION |
| ACTIVITY LEVELS DUE TO THE CONTROL ROOM VENTILATION SYSTEM SUPPLY BEING |
| ISOLATED. FIVE MINUTES FOLLOWING THE ACTUATION, THE RADIATION MONITOR |
| INDICATED 300 CPM. THE MONITOR PRESENTLY INDICATES THE NORMAL INDICATION OF |
| 90 CPM. THE RVSF WAS SECURED 2 MINUTES FOLLOWING THE ACTUATION OF VSF-9. |

| During a planned plant shutdown, with the reactor already subcritical, |
| control bank 'A' group 2 did not move as rods were being inserted. As a |
| result, the rod control system received an "Urgent Alarm" which inhibited |
| manual control rod motion. The licensee performed a manual trip and all |

| |
| Heat removal was and is by steam dump to the main condenser with feedwater |
