AGREEMENT STATE REPORT - CONTAMINATION EVENT
The following information was obtained from the State of Tennessee via email:
"On 12/10/12 at 4:30 pm EST, [the] RSO [at] Energy Solutions-Bear Creek called [the State of Tennessee] to report that last Friday, 12/7/12, a drum of DU shavings had been placed in Area 9 of the old ATG building and covered w/mineral oil. When [workers] came to work on 12/10/12, they noticed that the poly drum was completely gone, the shavings were on the floor, oil was on the floor and some of the shavings looked like ash. The poly drum had burned up and the drum/shavings and oil/ash/shavings were now on the concrete floor. There was no stack release. The stack samples were pulled and indicated less than MDA: < E-14 for U-238 and

AGREEMENT STATE - SOURCE DISCONNECTED FROM RADIOGRAPHY CAMERA
While conducting radiography operations with a Sentinel Model 880D camera, the radiographer noticed that the connection to the source was not holding. The radiographer was qualified in source retrieval. He was able to retrieve the source into its secured position. After securing the source he inspected the camera to determine if there was a mechanical problem. No problems were found. It is believed that the problem was due to ice buildup. There were no significant exposures during this event. |

PLANNED MAINTENANCE AFFECTING THE ABILITY TO ASSESS AN EMERGENCY CLASSIFICATION
"Voluntary ENS Notification Regarding Maintenance Affecting the Ability to Assess an EAL Classification.
"Kewaunee Power Station (KPS) is preparing to perform routine planned calibrations on Wednesday, December 19, and Thursday, December 20, 2012, on the forebay level indication. This maintenance will impact the forebay level computer and Control Room indication normally used to make the Unusual Event or Alert emergency classifications in the event the lake or forebay threshold is exceeded for greater than 15 minutes.
"The maintenance is planned to occur from 0800 [CST] on 12/19/12 until 1230 [CST] on 12/20/12. There are four level transmitters each with local indication. Each transmitter will be calibrated, but only one at a time, so that the capability to locally determine forebay level using the other three transmitters will remain.
"This activity has been evaluated against the requirements of 10 CFR 50.72(b)(3)(xiii) and it has been determined that the condition does not rise to the significance necessitating an event notification since Kewaunee retains the capability to make the necessary emergency classifications. However, this information is being conservatively provided so that NRC may be aware of the condition should an emergency develop."
The licensee notified the NRC Resident Inspector. |

AUTOMATIC REACTOR SCRAM DUE TO LOW REACTOR PRESSURE VESSEL LEVEL
"At approximately 17:31 hours on December 19, 2012, Susquehanna Steam Electric Station Unit Two reactor automatically scrammed on low RPV level (Level 3, +13 inches) while transitioning the 'A' reactor feed pump from discharge pressure mode to flow control mode.
"All control rods inserted and both reactor recirculation pumps tripped. Reactor water level lowered to approximately -29 inches causing Level 3 (+13 inches) isolations. An automatic trip of the reactor recirculation pumps occurred, but is not expected at this RPV level. There were no automatic emergency core cooling system initiations. No steam relief valves opened during the event. All safety systems operated as expected. The cause of the loss of feed water flow and trip of the reactor recirculation pumps is under investigation.
"This report is being made per 10CFR50.72(b)(2)(iv)(B) for a 4 hour report, and 10CFR50.72(b)(3)(iv)(A) for an 8 hour report."
Decay heat is removed via steam to the main condenser using the bypass valves . On-site electrical power is in the normal configuration. The Unit 2 reactor is currently stable in Mode 3. Unit 1 was not affected and operates at 99% power.
The licensee will inform the Commonwealth of Pennsylvania and make a press release. The NRC Resident Inspector was notified. |

GROUNDWATER SAMPLES INDICATE ELEVATED TRITIUM LEVELS
"On December 19, 2012, 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. Immediate actions are being taken to locate the source of the leak and actions are in progress to stop the leak. The investigation currently shows that the tritium is confined to a small area on the plant site in the vicinity of the Unit 1 Condensate Storage Tank (CST), 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 [SNC] 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 SNC's groundwater protection procedures and the Nuclear Energy Institute (NEI), SNC contacted the NRC Region II Resident Inspector and will be notifying the State of Georgia Environmental Protection Division and other agencies to inform them of this matter." |
