AGREEMENT STATE REPORT- DAMAGED SOIL MOISTURE NUCLEAR DENSITY GAUGE
The following information was received from the State by facsimile:
"Notifications: Licensee called the Pennsylvania Emergency Management Agency (PEMA), who then contacted Department of Environmental Protection (DEP) via phone on July 7, 2011 @ 1540. This event is 24 hour reportable under 10CFR 30.50(b) (2).
"Event Description: A CPN Model MC3 soil moisture Nuclear Density Gauge with cesium-137 and americium-241 sources was damaged while in use. Specifically, the rod with the Cs-137 source was damaged during a field measurement. However, the licensee was able to pull the rod back enough to get the nuclear gauge in the DOT ship container. Per CPN specs, the source is an industrial type 10 millicurie Cs-137 source with double encapsulation.
"Cause of the Event: A truck owned and operated by GA Covey Engineering drifted back over a CPN moisture density gauge bending one of the probe rods, leaving the Cs-137 source extended.
"Actions: The gauge was inspected by the company's regional RSO. It was determined that the source was still contained within the probe rod and managed to fit it back into the shipping container and secure it in the company truck. The licensee secured the area around the truck until a confirmatory survey was performed by PA DEP Emergency Response staff. The gauge was then brought to a secure site in PA for storage. The licensee will work with CPN to have the nuclear gauge repaired."

AGREEMENT STATE REPORT- UNDEREXPOSURE
The following information was received from the Commonwealth by facsimile:
"The RSO reported that a patient was 60% underexposed by an Ir-192 remote after-loader. The prescribed dose is not known. The error occurred because the physicist did not calculate the effect of the tube used to deliver the after-loader source. The target organ was the skin."
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. |

OVERFLOW OF CONDENSER CIRCULATING WATER
"At 0023 on 07/13/2011, a notification to an outside state agency, Tennessee Department of Environment and Conservation (TDEC), was made due to an overflow of Condenser Circulating Water from the northwest corner of the diffuser pond through a heavily vegetated area into a slough adjacent to the Sequoyah Training Center. Condenser Circulating Water is also discharging to the river via storm water outfall 14 near the cooling towers as well as the normal diffuser pond discharge at outfall 101.
"At approximately 1545 on 07/12/2011, one of the two diffuser gates at Sequoyah failed and shut off the west diffuser pipe. The other diffuser remained open throughout the event. Plant personnel made several attempts to raise the diffuser gate utilizing divers and cranes. When it was determined the crane could not lift the diffuser gate, both units reduced power to 85% and one (1) Condenser Circulating Water pump for each unit, two (2) pumps total, were removed from service. Diffuser pond level is currently lowering."
The NRC Resident Inspector has been informed. |

MOISTURE DENSITY GAUGE SHUTTER STUCK IN THE CLOSED POSITION
Tennessee Valley Authority Paradise Fossil Plant uses an Ohmart Model SR1-A density gauge with a sealed source containing up to 1,562 milliCuries of Cesium 137. The gauge is used to monitor the density of the limestone slurry at the Unit 2 scrubber. On July 12, 2011 at 1330 (CDT) the shutter on the density gauge was determined to be not operable. It was determined that the shutter failed in the closed position when the operator received a slurry density high alarm.
The shutter failure is in the closed and safe position. The gauge has been entered into the corrective action program and will be repaired by the manufacturer at a later time. There were no personnel exposures, no damages to other equipment, and no additional compensatory actions necessary since the shutter is failed closed/safe position.
The licensee notified the R2DO (Freeman). |

INAUDIBLE CRITICALITY WARNING SIREN
"At approximately 1730 on 7/12/2011, a regularly scheduled test of the inside Criticality Warning System (CWS) covering the Fuel Manufacturing Operation (FMO) was conducted. It was discovered that a CWS warning horn in the ChemMet lab was determined to be inaudible. Compensatory measures were immediately implemented. All other horns of the inside CWS in all other areas were functional and clearly audible. The affected area will remain shut down pending an investigation and implementation of additional corrective actions. The event is being reported within 24 hours pursuant to 10CFR70.50(b)(2) as a safety equipment failure. A CWS warning horn in the ChemMet lab was determined to be inaudible. All other CWS warning horns operating correctly. Investigation results pending. Affected area access was restricted. The faulty CWS horn has been replaced and tested."
The licensee notified Region 2(Coovert) and will notify the state radiation protection agency and New Hanover Emergency Management. |
