Event Notification Report for June 06, 2005

AUTOMATIC REACTOR SCRAM DUE TO APPARENT GENERATOR LOAD REJECTION

"At approximately 1233 hours, the Susquehanna Unit Two reactor automatically scrammed due to an apparent generator load reject. All rods inserted, and both reactor recirculation pumps tripped. Reactor water level lowered to -6" causing level 3 (setpoint +13") isolations, and was restored to normal level (+35") by the feedwater system. All isolations at this level occurred as expected. Two steam relief valves opened, then reclosed. Pressure was subsequently controlled via turbine bypass valve operation. All safety systems operated as expected. Some balance of plant loads shutdown apparently due to a voltage perturbation.

"A reactor recirculation pump was restarted to re-establish forced core circulation. The reactor is currently stable in condition 3. An investigation into the cause of the shutdown is underway. Unit One continued power operation.

"The NRC resident inspectors were notified. A press release will occur."

The licensee will be notifying the State of Pennsylvania.

IRRADIATOR SOURCE STUCK OUTSIDE OF WATER SHIELD

Testing was being performed on the panoramic pool irradiator (wet-source storage, cat IV). Two sources were pulled from the water for scram time testing. One of the sources fell back to its storage position however, the second source failed to return to storage. The source is a Co-60 source of approximately 180,000 Curies. The licensee expects to troubleshoot the problem and return the source to its storage location within the next four days (end of the week). The source is stuck eight feet below the water line and the irradiator room is locked.

* * * UPDATE FROM S. MILLER TO HOWIE CROUCH @ 1103 HRS. EDT ON 6/7/05 * * *

Through troubleshooting efforts, the licensee was able to return the stuck source to its normal storage location. There were no exposures as a result of this event or the troubleshooting effort.

Notified R1DO (Jackson), NMSS EO (Hickey) and IRD (McGinty).

FLORIDA AGREEMENT STATE REPORT - LOST AM-241 SOURCE

The following information was obtained from the State of Florida Bureau of Radiation Control via e-mail:

"Searle marker containing Am-241 source was reported missing from Children's Hospital Miami. Device was bought in early 1980's. This source is in a 'storage only' mode and was last seen during the May 2005 inventory. Florida is investigating."

The device description is a Searle marker, manufacturer and model unknown, serial number ACM-24, containing 14 milliCuries of Am-241.

Florida Incident Number FL05-088

LOST OR STOLEN VIAL OF PHOSPHORUS 32

"In accordance with 10 CFR 20.2201 Reports of theft or loss of licensed material [the Penn State University Radiation Safety Officer called] to report missing radioactive material in excess of 10 times the quantity specified in appendix C to part 20. The missing material is one vial of phosphorus-32. The vial contained a nominal 74 MBq (2 milliCuries) of P-32. The material in question was never in the possession of Penn State University.

"On June 4, 2005, a Type-A package containing three vials of radioactive P-32 was shipped from California to Penn State University via FedEx (tracking number 689818990843). When the package arrived at Penn State University on June 6, 2005, it only contained two of the three vials of P-32. When the vendor was contacted by Penn State University personnel, the vendor insisted that the material had been placed inside the package as was indicated on the shipping papers. The Penn State Health Physics Office staff member who opened the package reported that the security seal tape was properly attached and that the package displayed no evidence of tampering.

"The frozen liquid radioactive material that was not received was in the chemical form of Adenosine 5-Triphosphate (gamma P-32) End Labeling (P-32). Lot number J5E32. The package also contained dry ice.

"All other packages in the shipment were double checked to verify that the vial was not present in a separate package. The activity reported on the package's shipping label indicated the that the vial was within the package, the shipping papers indicated that the vial was within the package. The package was shipped by the vendor via FedEx in accordance with their normal procedures."

The licensee does not believe the box was opened or the material misdirected.

Received a call from the State of California Rad Program representative. During a followup investigation by CA, it was determined that only two of the three vials ordered had been shipped. CA would update the original licensee NMED report to show that there was no missing rad material. Notified R4DO(Pick) and NMSS(Morell).
