AGREEMENT STATE REPORT - DAMAGED PORTABLE MOISTURE DENSITY GAUGE

The following report was received via facsimile:

"On Friday, September 23, 2011 the Radioactive Materials Program (RMP) received notification from the Virginia Department of Emergency Management (VDEM) regarding a transportation accident on I-64 at mile marker 167 in Goochland County. The accident involved a moisture density gauge. The RMP contacted the on-scene Incident Commander (IC) to receive details. The IC stated that a truck carrying the gauge had lost control and the gauge was breached on the road. The driver of the vehicle was available and a conversation was held during which he stated he had lost control and the transport case handle was broken off allowing it to become free from the back of his truck. He stated the case opened and the gauge was destroyed. The driver contacted the RSO who then drove to the incident. The RSO brought a survey meter and another transportation case. The RSO stated the source rod had been sheared off at the shielding base but that radiation readings were within tolerance. The RSO packaged the shield and other gauge parts into the new transport case and returned the transport case to their office location. An RMP employee was dispatched to the licensee's office to investigate the incident and perform surveys of the transport case. The investigation is ongoing including interviews of the RSO and driver. The manufacturer (lnstroTek) was contacted and instructions were discussed. A leak test wipe was taken and is being sent to lnstro Tek for analysis."

AGREEMENT STATE REPORT - LEAKING 8 MILLICURIE NICKEL 63 SOURCE

The following report was received via facsimile:

"The Radiation Safety Officer (RSO) for Virginia Tech notified the Virginia Radioactive Materials Program on September 23, 2011 that a leaking source had been identified on June 28, 2011. The source was an 8 millicurie (April 1989) nickel-63 source used in a Varian gas chromatograph. The source was contained in a detector kit model 02-001972-00, serial number A7074. The gas chromatograph was no longer used. While preparing the unit to be surplussed, the RSO identified contamination of 0.07 microcurie in the area where the ECD (electron capture detector) had been installed. The RSO reported that he did not report the leaking source in June because leak tests of the ECD itself showed no continuing leakage. The RSO indicated that the gas chromatograph would be decontaminated and that procedures would be modified to specify the required five-day reporting requirement for a leaking source to prevent recurrence of late reporting."

AGREEMENT STATE REPORT - STUCK SHUTTER ON FIXED PROCESS GAUGE

The following information was received from the Texas Department of State Health Services via e-mail:

"On September 26, 2011, the licensee reported that while preparing to enter a vessel, the shutter on a Ronan model SA-1 nuclear gauge containing 2000 millicuries of Cesium (Cs) -137 failed to shut and is stuck in the normally open position. The source serial number is 2943GK. No significant exposure has occurred due to this event. The gauge is located at a height of 150 feet on the tank. The licensee contacted a technical representative and expects to repair or replace the gauge at the end of the week. The cause for the event is under investigation. Additional information will be provided as it is received IAW SA 300."

UNUSUAL EVENT DECLARED DUE TO FIRE ALARM IN THE CONTAINMENT

During plant startup, a single train fire alarm was received in containment at 0540 EDT on 9/29/2011. An Unusual Event was declared at 0602 EDT based on the containment not being accessible within 15 minutes. An inspection in containment revealed no fire or smoke or the cause for receipt of the alarm.

The licensee has notified the State, Counties and the NRC Resident Inspector.

GEORGIA DEPARTMENT OF NATURAL RESOURCES NOTIFIED DUE TO TRITIUM LEVELS ABOVE BACKGROUND DETECTED AT SAMPLE POINTS ONSITE

"On Sept. 28, 2011, results from routine monitoring of groundwater at Plant Hatch indicated tritium was detected above historical background levels at two sample points on site. Additional samples were taken from the same points and analysis confirmed that tritium was present at elevated levels in both samples and that tritium had not migrated out of the general area of initial discovery. Tritium concentrations up to 5.34 million picocuries per liter were observed. Immediate actions were taken to locate the source of the leak and actions are in progress to stop the leak. The tritium is confined to a small area on the plant site in the vicinity of the Unit 1 condensate storage tank, and there is no significant potential for off-site impact. Additionally, there is no impact to on-site personnel. No tritium levels above background have been detected or migrated outside the area where the two sample points are located.

"Southern Nuclear will continue to sample strategic locations in the ground water monitoring network to determine if there are changes in the impacted area and beyond. SNC is confident that these levels are of low safety significance and do not pose any issues to the public health and safety.

"In accordance with Southern Nuclear's groundwater protection procedures and the Nuclear Energy Institute (NEI)/Industry Groundwater Protection Initiative, Southern Nuclear contacted the Nuclear Regulatory Commission (NRC) Region II Resident Inspector and the Georgia Department of Natural Resources to inform them of this matter."

INADEQUATE SURVEILLANCE TESTING OF EMERGENCY DIESEL GENERATORS

"Monticello has discovered that it has not met Technical Specification Surveillance Requirement (SR) 3.8.1.7 relating to the largest single post-accident load reject for the Emergency Diesel Generators (EDG). Although the current test designated post-accident load is successfully load rejected during the surveillance, the test load rejection must be higher to bound all post-accident load scenarios. The capability of an EDG subsystem to recover from a reject of the largest single post-accident load testing has not met the requirements of SR 3.8.1.7. Therefore, both EDGs have been declared inoperable. Both EDGs are considered Functional and Available for use at this time.

"There were no automatic EDG initiation signals associated with this event."

The licensee notified the NRC Resident Inspector and will notify the State.
