| UNUSUAL EVENT DUE TO AUXILIARY TRANSFORMER EXPLOSION & FIRE; LOSS OF OFFSITE |
| POWER - |
| |
| At 0043 PDT on 05/15/00, the licensee declared an Unusual Event due to |
| auxiliary transformer #1-1 exploding and catching on fire. This resulted in |
| the loss of offsite power and an automatic trip of Unit 1. The licensee |
| called the offsite fire department and they responded to the plant. |
| Auxiliary transformer #1-1 is located outside the turbine building (north |
| end). |
| |
| Three of three Unit 1 emergency diesel generators started and loaded and are |
| supplying emergency power to vital Unit 1 buses. Auxiliary transformer #1-1 |
| supplies backup power to Unit 1 emergency buses. The Unit 1 12 KV buses are |
| energized. Unit 1 reactor coolant pumps are running providing forced |
| circulation. |
| |
| Unit 1 automatically tripped from 100% power. All control rods inserted |
| completely. Steam is being dumped to the atmosphere. Unit 1 has no steam |
| generator tube leaks and no fuel leaks. The auxiliary feedwater system |
| automatically started, as expected. A #1-2 steam generator code safety |
| valve failed open for about 25 - 30 minutes about 30 minutes after the |
| reactor trip. The valve is now closed. There was no safety injection |
| actuation. |
| |
| Unit 1 is stable in Mode 3 (Hot Standby). |
| |
| This event had no effect on Unit 2 which is stable at 100% power. |
| |
| The licensee notified state and local officials and the NRC Resident |
| Inspector. |
| |
| At 0143 PDT, the fire is out. No personnel were injured. |
| |
| At 0405 CDT, NRC Region 4 entered the Monitoring Phase of Normal NRC |
| Response Mode. |
| |
| * * * UPDATE AT 0726 ON 05/15/00 FROM MARK LEMKE TO JOLLIFFE * * * |
| |
| The licensee determined that an electrical fault on the low voltage side of |
| auxiliary transformer #1-1 caused extensive damage to the 12 KV buswork and |
| nearby buswork used to supply the Unit 1 4 KV buses from offsite power |
| following a plant shutdown. Auxiliary transformer #1-1 did not explode and |
| is intact. |
| |
| The licensee also determined that there was not a failure of a main steam |
| code safety valve. However, following closure of the main steam isolation |
| valves, a code safety valve on the #1-2 steam generator did lift and did not |
| fully reseat. Plant operators took manual action to lower steam generator |
| pressure, causing the valve to reseat. There was no release of radiation |
| from the plant. |
| |
| The California Department of Forestry responded to the site. |
| |
| The licensee is continuing to investigate the cause of this explosion and |
| has issued a press release. |

| OUTBOARD MAIN STEAM ISOLATION (MSIV) VALVE FOUND CLOSED. |
| |
| At 0448 PDT on 05/15/00, the outboard main steam isolation valve #MSIV-V-28A |
| was found in the closed position (green indicating light on). Followup |
| verification of the 'A' main steam line flow (0%) and the plant computer |
| valve position verified that the valve was closed. The plant computer |
| indicated that the valve closed at 0254 PDT and it was discovered closed at |
| 0448 PDT. No work was being performed on the main steam system or in the |
| area of the main steam system when the valve closed. The plant computer |
| indicated that the valve had fast closed. The plant entered the Limiting |
| Condition of Operation for Primary Containment Isolation Valve and placed |
| the control switch for the MSIV in the closed position. There was no valid |
| ESF Actuation signal that caused the valve closure. The plant was operating |
| at 62% power and did not experience a transient as a result of the MSIV |
| closure (no flux tilt). Licensee investigation into the cause of the |
| closure is continuing. |
| |
| The NRC Resident Inspector was notified of this event by the licensee. |

| LOST DEPLETED URANIUM SHIELD WITH USED TECHNETIUM-99 GENERATOR |
| |
| On April 23, 2000, a depleted uranium (DU) shield was declared lost in |
| accordance with Mallinckrodt, Inc. (Ml) site procedures for tracking and |
| accountability of this material. |
| |
| This shield was shipped as part of a Mo-99/Tc-99m Generator from the |
| Maryland Heights facility on March 12, 1999. It was shipped to a |
| Mallinckrodt, Inc pharmacy in North Attleboro, MA. The pharmacy received |
| the generator and it was offered for return shipment to our site on March |
| 31, 1999. At the time it was offered for shipment, the safe also contained |
| a generator column with approximately 440 mCi of Mo-99. The generator was |
| shipped via Del Med, Inc. The generator went to a Del Med warehouse in |
| South Plainfield, NJ and was stored until April 8, 1999. Del Med records |
| indicate the package was then shipped to the Maryland Heights facility via |
| Associated Courier. Associated Courier has indicated the generator was |
| returned to the Maryland heights facility. |
| |
| Return generator packages are not tracked by the couriers with an individual |
| package number. The packages are generally collected on a pallet in the |
| courier's warehouse and transported to Maryland Heights when a pallet is |
| full. They generally arrive at Maryland Heights with a single bill of |
| Lading. We do not become aware of a particular generators serial number |
| until the package is inspected, opened, and the generator bar code is |
| scanned into our system. We have no record of this generator being scanned |
| back into our system. This indicates to us that it never arrived on our |
| site. We have no record of this DU shield returning to the Maryland Heights |
| facility. If the safe was reused without check-in, it would have shown up |
| on subsequent scanning when shipped from our facility or upon arrival after |
| it's subsequent use. Mallinckrodt believes the package was not delivered to |
| the Maryland Heights facility and was lost in the transportation cycle. The |
| location of this safe is unknown to Mallinckrodt and the carriers involved |
| in it's transportation. |
| |
| Our site procedures allow a one year time frame for a depleted uranium |
| shield to be returned to our site after the expected return date. This |
| allows time for customers to utilize the generator and make necessary |
| transportation arrangements, couriers to search their warehouses, and time |
| for the shields to cycle through Mallinckrodt's systems. This package had |
| an expected return date of April 23, 1999. The one year time frame for this |
| missing safe expired on April 23, 2000. |
| |
| As part of our investigation, we contacted the original pharmacy and the two |
| couriers who handled this package. The pharmacy has provided a copy of a |
| bill of lading indicating they offered the DU safe for shipment. The |
| couriers have indicated they have conducted a search of their warehouses and |
| do not have the DU safe in their possession. |
| |
| The safe itself contains approximately 8000 �Ci of U-238 metal encapsulated |
| in stainless steel. The safe is stamped with the legend |
| "Caution-Radioactive Shielding-Uranium" in accordance with 10CFR40.13(c)(6). |
| The dose rate on contact with the DU safe is approximately 3 to 4 mrad/hr. |
| As a result of the construction of the safe, and the low dose rates |
| exhibited by this material, no significant exposures would be expected to |
| members of the public. |
| |
| MI has been in contact with NRC Region 3 (James Cameron). |

| REPORTABLE QUANTITY FOR OIL DISCHARGE EXCEEDED |
| |
| "On 05/15/00 at 1530, it was determined that the Reportable Quantity (RQ) |
| value for oil (i.e, greater than 25 gallons) was exceeded. Operations |
| personnel reported that a lubrication oil spill had occurred on the roof of |
| the X-330 Process Building and after an investigation was initiated by |
| Environmental Compliance personnel, it was determined that the total |
| quantity of the spill was approximately 500 gallons. The cause of the spill |
| is still under investigation. |
| |
| "The spill resulted in a release of oil to the environment exceeding the RQ |
| in accordance with Ohio Administrative Code Rule 3750-25-20 thereby |
| initiating the release reporting requirements contained therein. Oil was |
| discharged via the storm sewer system to the X-230J-7 East Holding Pond and |
| the southernmost branch of the West Drainage Ditch. |
| |
