The gauge contained 10 mCi of Cs-137 (s/n9733GQ) and 40 mCi of Am-241 (s/nNJ03934). The Louisiana State Police notified LA DEQ of the accident and stated that the overpack was not breached and that readings at the surface were 0.9 mR/hr. The gauge and overpack were inspected at the DOTD district laboratory that was 0.5 miles from the accident. The overpack was in overall excellent condition except for a small hole (approximately 1 inch in circumference) which had been punched through the exterior wall but did not puncture the interior wall of the overpack. The overpack and gauge were surveyed by a DEQ inspector and recorded readings of 0.2 mR/hr at 1 meter which, correspond to the transportation index. A leak test has been sent off for the gauge and the results are pending. Will update with further information when it becomes available."

The receipt of the NRC 2006-25 instruction letter prompted Wyodak plant to do an inventory of Tritium exit signs and review the NRC standards and rules. When reviewing the 10CFR20.2201 rules in regards to missing sources, Wyodak plant subsequently started an investigation and discovery of the now missing Tritium exit signs. "The following is a brief description of our investigation of missing Tritium exit signs: "In 1993 a contractor (Montague) was hired to build a new coal handling facility at Wyodak plant that is owned by Black Hills Power and PacifiCorp Energy. An assumption is made that the contractor ordered 22 Tritium self luminating exit signs from Isolite and installed them in the new coal facility. The contractor (Montague) who built the Secondary Crusher Facility is no longer in business to verify any of the assumptions. "During the facility construction most of the new coal handling facility was being handled by Black Hills Corporation. Later owner / operator lines were finalized and PacifiCorp Energy took over operation of the facility. "In about 1999 the coal handling operator's control building which was a part of the 1993 facility was torn down. It is believed that two of the 1993 Tritium exit signs were destroyed with the demolition of this building. "In 2003 Isolite notified PacifiCorp that the 22 self luminating Tritium exit signs purchased in 1993 were about to come to the end of their effective life. This call is what leads us to the assumption that 22 Tritium signs were purchased and installed in 1993. From the Isolite telephone call in 2003 PacifiCorp Energy's Wyodak plant purchased 22 new Tritium exit signs to replace the original 1993 signs. A work order was written to change out the old signs. The work order was never completed. "From the ongoing investigation we now believe that only 16 of the original 22 Tritium exit signs were installed by the contractor (14 in the coal handling facility and 2 in its control building). It is assumed that 6 of the Tritium exit signs left the plant at the end of the 1993 construction with the contractor. "We are currently working with Isolite to identify the serial numbers of the missing Tritium exit signs. "Disposition of the radioactive material: "6 - Tritium exit signs with 7.5 curries each are assumed to have been taken by the contractor (Montague) in 1993 - lost and not recoverable. "2 - Tritium exit signs with 7.5 curries each were hauled to trash with the demolition of the coal operators control building in 1999 assumed lost and not recoverable. "2 - Tritium exit signs with 7.5 curries lost by plant in 2003 assumed to be in a landfill and not recoverable. "2 - Tritium exit signs with 11.5 curries, S/N's 224944 and 224947 lost by plant somewhere between 1993 and 2007 assumed to be in a landfill and not recoverable.. "Radiation exposure to individuals: "It is believed that no individual exposure took place or any individual risk was involved. "Actions taken to recover the material: "Plant personnel have made a comprehensive search throughout the plant, plant storage and shop areas, plant warehouses, and coal facilities. Plant tried to make contact with the original installation contractor (Montague) but the company has gone out of business. Interviewed employees that might have had any knowledge of the Tritium exit signs. The results of the plant investigation are reported above. "Actions taken to prevent recurrence. "Wyodak Plant has completed an inventory of the 1993 and 2003 signs. Maps have been made of Tritium exit signs in use. "A corporate policy has been initiated on the use and handling of Tritium exit signs. An annual inventory list with model and serial numbers has been created for tracking and inventory purpose. Employees responsible for the ordering, disposal, and installation of Tritium signs will receive annual training on the corporate policy." 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.

This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source | Power Reactor | Event Number: 44034 | Facility: RIVER BEND Region: 4 State: LA Unit: [1] [ ] [ ] RX Type: [1] GE-6 NRC Notified By: TIM SCHENK HQ OPS Officer: PETE SNYDER | Notification Date: 03/05/2008 Notification Time: 17:44 [ET] Event Date: 03/05/2008 Event Time: 14:43 [CST] Last Update Date: 03/05/2008 | Emergency Class: NON EMERGENCY 10 CFR Section: 50.72(b)(2)(iv)(B) - RPS ACTUATION - CRITICAL | Person (Organization): CHUCK CAIN (R4) | Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | 1 | A/R | Y | 60 | Power Operation | 0 | Hot Shutdown | Event Text AUTOMATIC SCRAM DUE TO APPARENT MALFUNCTION IN TURBINE CONTROL SYSTEM "At 2:43 p.m. CST, an unplanned automatic reactor scram occurred. The initial investigation determined that the event resulted from an apparent malfunction in the main turbine control system. This had the effect of causing reactor steam pressure to exceed the trip set point for the reactor protection system, initiating the reactor scram signal. All reactor control rods inserted, and the main feedwater system remained in service. Reactor safety-relief valves initially lifted as a result of the pressure transient. Reactor pressure is now being controlled by steam line drains with turbine bypass valves as a backup. There was no condition requiring the actuation of emergency diesel generators or emergency core cooling systems."

This dissimilar metal weld is located on the nozzle to the Decay Heat System drop line piping, which is the common suction line from the Reactor Coolant System and is a 12 inch outer diameter pipe. The indication is circumferential, is 15 inches in length, and reaches a maximum localized depth of 65 percent through-wall in one location. The weld was previously partially inspected during the November 2007 refueling outage using manual ultrasonic examination and no indications were identified. The current inspection was done using newly qualified phased array ultrasonic examination techniques in response to industry operating experience regarding dissimilar metal weld flaws. The indication has been found unacceptable per paragraph IWB 3514.4 of the 1989 Addenda of ASME Section XI without further fracture mechanics analysis and is therefore considered reportable. "Preparations for a weld overlay repair and further confirmatory manual ultrasonic testing examinations are in progress. "The licensee notified the NRC Resident Inspector." | |
