OFFSITE NOTIFICATION DUE TO A CONTAINED ON-SITE LIQUID RADWASTE LEAK
"This notification is being made under 10 CFR 50.72(b)(2)(xi) of a situation related to the protection of the environment for which a notification to a state agency has been made. On July 8, 2011, South Carolina Electric & Gas Company (SCE&G) made a voluntary notification to the South Carolina Department of Health and Environmental Control (SCDHEC) in accordance with the Nuclear Energy Institute (NEI) Groundwater Protection Initiative for an on-site leak that may exceed 100 gallons. The leak was entirely contained within the V. C. Summer Nuclear Station site boundary.
"On July 7, 2011 during a routine inspection, a leak was discovered in a liquid radwaste line upstream from its final discharge point and downstream of the release radiation monitors. This line contains processed liquid radwaste that has been sampled and permitted for release. The leak occurred inside a containment enclosure which overflowed. The enclosure was drained and the liquid was returned to the plant for disposal. The leak has been isolated and all radwaste release via this pathway has been suspended. The last inspection of this equipment was conducted on February 14, 2011, and revealed no external leakage."
The licensee notified the NRC Resident Inspector.

EMERGENCY SIREN OUTAGE
"At 0900 EDT, the Shift Manager was notified that all off site notification sirens were discovered inoperable during the daily maintenance checks due to a loss of power supply. Upon discovery by the technicians of the loss of power supply, the backup power supply was energized and all sirens were tested and returned to operable status.
"The time of power loss is unknown at this time and the reason for the failure of the transfer to the backup power supply appears to be a bad solder joint.
"The backup power supply has been verified SAT."
The sirens were last tested satisfactorily on Tuesday, 7/5/11.
The licensee notified the NRC Resident Inspector.

LOSS OF POWER TO 10 EMERGENCY SIRENS
"Power has been removed from 10 (out of 101) sirens due to flooding conditions. [Three] out of 5 sirens in Pottawattamie county, 4 of 18 in Harrison county and 3 of 78 in Washington county. There are compensatory measures in place to ensure notification to any members of the public that may still be in these areas. The station is also suspending testing and reporting (performance indicator) data for these sirens in accordance with NEI 99-02. All of these sirens serve areas for which there are no residents requiring evacuation. This is being reported per 10CFR50.72(b)(3)(xiii)) for 'Any event that results in a major loss of emergency assessment capability, offsite response capability, or communications capability'."
The licensee notified the States of Nebraska and Iowa, the Counties of Harrison, Washington and Pottawattamie and the NRC Resident Inspector of this report.

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."
