| THE RADIOLOGICAL HEALTH BRANCH OF THE CALIFORNIA DEPARTMENT OF HEALTH |
| SERVICES WAS NOTIFIED BY STERIGENICS INTERNATIONAL THAT THEY HAD A CABLE JAM |
| ON THEIR SOURCE HOIST ARRAY. |
| |
| THIS OCCURRED ON THEIR 600,000 CURIE POOL IRRADIATOR WHILE THEY WERE |
| LOWERING THE SOURCE ARRAY INTO THE SHIELDED POSITION AND THE SOURCE HOIST |
| CABLE JAMMED DUE TO A FRAY ON THE CABLE. THEY LOOSENED THE SHIELDING AROUND |
| THE SOURCE HOIST CABLE AND THAT ALLOWED THE SOURCES TO BE RETURNED TO THE |
| SAFE POSITION. THERE WERE NO OVEREXPOSURES AND NO ABNORMAL RADIATION |
| LEVELS. THE PLANT WAS SHUTDOWN UNTIL MAINTENANCE WAS COMPLETED THIS MORNING |
| @ 6:00. |

| THE PLANT HAD A REACTOR SCRAM FROM 100% POWER DUE TO LOW REACTOR WATER |
| LEVEL |
| |
| At 13:54 CDT, unit 3 reactor scrammed due to low reactor water level. All |
| rods fully inserted into the core. The expected groups 2, 3, 6 and 8 |
| isolations were received. Both recirc pumps tripped, all Standby Gas |
| Treatment trains started and the 'A' CREV started. The expected Refuel zone |
| and unit 3 reactor zone isolations were received. Both the HPCI system and |
| the RCIC system automatically initiated and injected due to low level |
| following the scram. The actual signal perturbation that caused the reactor |
| trip on low water level is still being investigated. Currently the plant is |
| in a stable condition in mode 3 with investigations in progress. No relief |
| valves lifted and HPCI was secured within the first 5 minutes and RCIC |
| secured a few minutes later. |
| |
| The NRC Resident Inspector was notified. |

| Licensee had a source disconnect occur due to a mechanical failure of the |
| drive cable connector. |
| |
| A source disconnect attributable to mechanical failure of the drive cable |
| connector occurred during use of a cobalt 60 radiographic exposure device on |
| May 11. Radiography is routinely conducted by this licensee in a shielded |
| vault (a permanent radiographic installation). An AEA Technologies Model 676 |
| cobalt 60 camera, serial number B105, is generally left set-up between |
| shots. The routine daily equipment check includes a visual check to confirm |
| that the drive cable and camera are still connected. The last quarterly |
| maintenance inspection was at the end of March 2000 and no problems with the |
| drive cable connector were noted. However, during the first shot of the day, |
| the radiographer noticed that the source did not go out smoothly and then |
| failed to retract. The RSO was contacted and after several more attempts to |
| retract the source the licensee decided to secure the area and call in the |
| manufacturer's retrieval experts. Additional shielding, locks and posting |
| were added and a survey of the area including the roof showed no readings |
| above 1 mrem per hour. The state Division of Radiation Protection was |
| notified and staff observed the retrieval on May 12. Once the source was |
| secured, the failed equipment was inspected. No problems were noted with |
| the source assembly or the camera. However, the ball fitting at the drive |
| cable connector's end had become separated from the cable. AEA Technologies |
| took the separated ball and 4 inches of the end of the drive cable back to |
| AEA for analysis. |
| |
| What is the notification or reporting criteria involved? WAC 246-221-250 |
| Notification of incidents (equipment failure) |
| |
| Activity and isotope(s) involved: 71 curies of Cobalt 60. |
| |
| Overexposures? There were no overexposures (however, retrieval personnel |
| received 130 and 65 mrem whole body exposures) |

| LICENSEE REPORTED A STOLEN PORTABLE GAUGE. |
| |
| The licensee reported on May 23 that at approximately 6:00 PM the previous |
| evening a Seaman Nuclear C-200 gauge, serial number A-872, with 4.5 |
| milligrams of Ra-226 was stolen. The licensee's technician had stopped by a |
| friend's house in South Seattle on his way home. While there, his pickup |
| truck was stolen from in front of the house. The gauge was locked, in a |
| locked transport box, and the box was chained and locked in the bed of the |
| truck. The licensee believes the thief wanted only the truck and will |
| probably abandon the gauge. The police were notified and the licensee was |
| advised to notify the local papers and post a reward. |
| |
| Overexposures? Unknown |
| |
| Disposition/recovery: Unknown at this time |

| MAIN TRANSFORMER EXPLOSION AND FIRE WITHIN FIVE FEET OF THE TURBINE |
| BUILDING. |
| |
| PRIOR TO THE EVENT, THEY HAD JUST CLOSED THE MAIN TURBINE AND GENERATOR |
| OUTPUT BREAKERS SO THAT THE TURBINE WOULD SYNCHRONIZE TO THE GRID. AT 1804 |
| A MAIN TURBINE TRIP AND MAIN TRANSFORMER TROUBLE ALARM WAS RECEIVED IN THE |
| CONTROL ROOM. SUBSEQUENT TO THE TURBINE TRIP, MAIN GENERATOR TRANSFORMER |
| FIRE ALARMS WERE RECEIVED AND VISUAL VERIFICATIONS CONFIRMED A FIRE ON THE |
| "C" PHASE OF THE MAIN GENERATOR TRANSFORMER. THE FIRE DELUGE SYSTEM |
| ACTIVATED, AND ALTHOUGH EXTERNAL INDICATION THE FIRE HAD CEASED, IT IS |
| EXPECTED THAT THE FIRE CONTINUES TO BURN INTERNALLY TO THE TRANSFORMER. ALL |
| OFFSITE POWER SOURCES ARE STILL AVAILABLE. NO OFFSITE FIRE ASSISTANCE HAS |
| BEEN REQUESTED. THE FIRE HAS BEEN ONGOING INTERNALLY FOR APPROXIMATELY TWO |
| HOURS. THEY ARE IN THE PROCESS OF ELECTRICALLY ISOLATING THE TRANSFORMER |
| FROM BOTH THE GENERATOR AND THE GRID AND TAGGING IT OUT. DELUGE ACTUATION |
| HAS BEEN SECURED AND THEY ARE SPRAYING THE TRANSFORMER WITH FIRE WATER. THEY |
| ARE ALSO MAKING PREPARATIONS TO USE A FOAM FIRE SUPPRESSION AGENT. |
| |
| FURTHER EVALUATION CONTINUES IN REGARD TO THE ENVIRONMENTAL IMPLICATIONS OF |
| THE EVENT. SPECIFICALLY, THE ABILITY OF THE PLANT OIL WASTE SYSTEM TO |
| PROPERLY PROCESS THE MIXTURE OF WATER AND OIL THAT WERE PRODUCTS OF THE |
| COMPONENT FAILURE AND SUBSEQUENT FIRE FIGHTING EFFORTS. |
| |
| THE LICENSEE WILL KEEP THE NRC INFORMED OF ANY ADVERSE CHANGES. |
| |
| THE NRC RESIDENT INSPECTOR WILL BE INFORMED. |
