"Operations identified a potential flooding issue in the Intake Structure 1007' 6" level. The areas of concern are the holes in the floor at the 1007' 6" level where the screen wash header penetrates the ceiling of the Raw Water Vault. There are five of these penetrations of concern. Flooding through the penetrations could have impacted the ability of the station's Raw Water (RW) pumps to perform their design accident mitigation functions.
"This eight-hour notification is being made pursuant to 10 CFR 50.72 (b)(3)(v).
"A one foot sandbag berm has been placed around each penetration of concern."
The licensee notified the NRC Resident Inspector.

"Following additional review of the reported condition, it has been determined that the Raw Water pumps are adequately protected during flooding conditions and that the open penetrations would not impact the ability of the Raw Water pumps to perform their design accident mitigation functions."

| Event Text DOSE DIFFERENT THAN PRESCRIBED
A patient was scheduled to receive three separate treatments for pancreatic cancer containing Yttrium-90. Each dose was to contain 10.5 milliCuries of Yttrium-90 for a total of 31.5 milliCuries. Cardinal Health (the producer of the treatment) provided the entire dose of 31.5 milliCurie in a single syringe. The physician verified the receipt of the syringe and administered it to the patient.
When the patient was scheduled to return on 8/16/11 for the second treatment Cardinal Health realized that they had provided the entire dose instead of three separate doses of 10.5 milliCuries. Cardinal Health notified Christiana Care of the error.
The treating physician and patient have been notified. No adverse health effects are expected.
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient. |

The following was received via email:
"On August 17, 2011, the Agency [Texas Department of Health] was notified that they were unable to open the shutter on a Ronan Engineering model GS 400 nuclear gauge. The gauge contains 20 milliCuries of cesium 137.
"The gauge had been taken out of service by the licensee to conduct maintenance in the area around the gauge. Once the work was completed, they were unable to get the gauge shutter to open. The licensee has taken the gauge out of service until it can be replaced.
"The gauge does not present an exposure hazard to anyone. The manufacturer has been contacted and is making arrangements to replace the gauge. The gauge was installed in 2010. The Radiation Safety Officer stated that the gauge has been cycled several times since it was installed. The licensee was not able to determine the cause for the failure. Additional information will be provided as it is received."

The following information was obtained from the State of Texas via email:
"On August 18, 2011, the Agency [Texas Department of State Health Services] was notified that a Humboldt model 5001 EZ, serial number 4220, containing a 44 milliCurie Americium-241/Beryllium source and an 11 milliCurie Cesium-137 source was run over by a dirt compactor. The user placed the device on the ground 12 feet from his truck to perform prior to use checks on the gauge. The sources were in the fully shielded position. When the technician went to the cab of their truck to record readings, a dirt compactor came up out of a pit near the truck. The technician could not get the attention of the compactor driver in time to prevent them from driving over the gauge. The technician contacted the fire department and [informed] his manager of the event. The licensee's Radiation Safety Officer (RSO) and fire department both responded to the scene. The RSO conducted a radiation survey of the device and determined that the sources were fully shielded. A service company was contacted and they took the device to their facility. The service company performed leak tests on both sources. The results were below the regulatory limit. Additional information will be provided as it is received."

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text GEORGIA AGREEMENT STATE REPORT - LOST INDUSTRIAL NUCLEAR GAUGE
On 8/17/11, the licensee discovered that a nuclear process gauge was missing. The gauge was suspected to have been placed in the trash and transported to a local landfill. The landfill operators have been notified. Workers at the facility were interviewed but the licensee could not determine the disposition of the gauge.
The gauge, a BSI Instruments model NW201, serial number 1041, was last seen on or about August 4, 2011. The missing gauge, plus two others, were verified to be in temporary storage awaiting transfer to an outside organization. The gauge contained 0.5 mCi of Cs-137. The two other gauges are accounted for and stored properly.
Georgia Report #: GA2011-40I
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.

| Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | | 1 | M/R | Y | 89 | Power Operation | 0 | Hot Standby | Event Text MANUAL REACTOR TRIP DUE TO RISING CONDENSER BACKPRESSURE
"On August 22, 2011 at 1513 [hrs. EDT], Unit 1 was manually tripped due to rising condenser backpressure. All CEAs fully inserted into the core. Decay heat removal was initially from main feedwater and steam bypass to the main condenser. The cause of the rising back pressure was an influx of jellyfish into the intake structure, degrading the circulating water system performance.
"Subsequent to the manual trip, the 1B Main Feedwater Pump was manually secured due to a leak on the pump casing. The 1A Main Feedwater Pump subsequently tripped due to low suction pressure after manually securing the 1B Condensate Pump, per procedure. Decay heat removal was transitioned to atmospheric dump valves and auxiliary feedwater.
"Unit 2 is in Mode 1, currently at 70 % power. Unit 2 power is being reduced from 100% in response to the influx of jellyfish.
"This event is reportable pursuant to 10 CFR 50.72(b)(2)(iv)(B) for the reactor trip."
During the transient, no primary or secondary relief valves lifted. Offsite power is stable and the plant is in its normal shutdown electrical line-up with power being supplied from offsite. There is no known primary-to-secondary leakage. The cause of the 1A Main Feedwater Pump trip is under investigation.
Unit 2 remained at 70% reactor power before and after the event.
The licensee has notified the NRC Resident Inspector.
* * * UPDATE AT 1856 EDT ON 08/22/11 FROM CARLOS SANTOS TO JOE O'HARA * * *
"On August 22, 2011 an abnormal fish kill of at least 1000 lbs was observed in the combined unit's intake canal. The cause of the fish kill was related to an unusually large sustained influx of jellyfish into the intake canal.
"Per the plant's environmental permit, the Florida Fish and Wildlife Conservation Commission (FWCC) was notified at 1627 EDT. This non-emergency notification is being made pursuant to 10 CFR 50.72(b)(2)(xi) due to the notification of the FWCC."
The licensee has notified the NRC Resident Inspector. | |
