"At 1835 on March 25, 2008, Unit 2 experienced a Loss of Offsite Power. At 1849, an Unusual Event was declared. Station Auxiliary Transformer (SAT) 242-2, Phase C, experienced a Phase Overcurrent. This resulted in an isolation of the SAT, a loss of offsite power, and an automatic Fire Protection deluge of the SAT. No fire was confirmed. All equipment responded as required. The appropriate abnormal operating procedure was entered for event mitigation and is in progress. The Unit 2 Emergency Diesel Generators are supplying required safety-related power. Unit 2 remains at power."
The plant is stable and all equipment is functioning as required. The licensee is assessing a cross-tie to Unit 1 which is unaffected by this event and in the refueling mode.
The licensee notified the State and local authorities and the NRC Resident Inspector. Notified DHS (Greg Ray), FEMA (Erwin Casto), DOE (Sal Morrone), USDA (Timmons), HHS (Rick Turner), EPA/NRC (Petty Officer Thompson Report #866038).
* * * UPDATE BY SCOTT PURIN TO NRC AT 2230 EDT ON 3/25/08 * * *
The emergency buses on Unit 2 have been re-energized by offsite power supply sources via Unit 1 SAT. The Unit 2 EDGs have been secured and placed back in standby. The licensee is developing a recovery plan to restore a Unit 2 SAT to supply offsite power to Unit 2 loads. This will require such things as analyzing chemistry samples of the affected SAT transformers and assessing the protective relaying. In addition, some switchyard realignment will be necessary. The licensee is currently in a 72 hour LCO under Tech Spec 3.8.1 for the current electrical alignment.
The NRC Resident Inspector is onsite and the NRC Region continues to monitor the situation.
* * * UPDATE FROM STEVE WIDOLFF TO HOWIE CROUCH AT 0022 EDT ON 3/28/08 * * *
"At 2309 [hrs. CDT] on 3/27/08, Byron Unit 2 terminated an Unusual Event that was declared at 18:49 on 3/25/08, in accordance with EAL M.U.1 due to a loss of offsite power to transformers 242-1 and 242-2.
"Transformer 242-1has been energized from offsite power and is supplying Unit 2 ESF busses 241 and 242. The entry conditions for M.U.1 are no longer met. A press release will be issued."
Transformer 242-2 is out of service and isolated for repairs.
The licensee notified the NRC Resident Inspector. Notified R3DO (Hills), NRR EO (Ross-Lee), IRD (McDermott), DHS SWO (Doyle), FEMA (Liggett), DOE (Morrone), EPA (Allison), USDA (Timmon) and HHS (Dalziel). |

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE - CALIFORNIA - STOLEN TROXLER GAUGE
The State provided the following information via email:
"On March 25, 2008, a Troxler M/D gauge, Model 3411, Serial Number 6520 was stolen from a URS company pick up truck during the evening. According to the RSO, the gauge was stolen from inside a locked container, which was stored in a locked camper shell, within a locked gated garage at the employees residence. The employee had taken the gauge to his residence in preparation for an early morning job. The density gauge was stated to contain approximately 9 mCi of cesium 137 and 44 mCi of americium 241. "
CA Report #032608
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. |

"On 3/29/08 at approximately 1100, oil waste was discharged from Units 1 and 2 into a storm drain which discharges into the cooling canal system. The discharge created an oil sheen approximately 10 feet in diameter. The oil slick is currently contained within an oil boom. The Department of Environmental Resource Management for Miami-Dade County was notified of the event at 1715."
This was a minor leak contained entirely within the owner controlled area with no path to major waterways.
