AGREEMENT STATE REPORT - DAMAGED EXIT SIGNS.
"On 10/30/08 the Agency [state] received a written report of damaged Tritium exit signs from Richard Dailey, RSO of Wal-Mart Stores. The 2 exit signs, manufactured by SRB Lite, are identified as S/N's 249470 and 249477 each containing 20 curies.
"During an inventory on 9/29/08 at the Northampton store, Wal-Mart's contractor discovered 2 damaged signs that failed the glow test. Additionally, one of the signs, S/N 249477, had a cracked face plate. Interviews with the store manager and associates indicated the signs were probably damaged during a recent remodel project. Wal-Mart hired Dade Moeller to assess the radiological impact of the damaged signs. A wipe survey was performed and the survey indicated no high levels of contamination. The signs were packaged per the protocols of Isolite, a specific licensee authorized to receive Tritium exit signs for disposal and transferred to Isolite. Wal-Mart will send the Agency a report of the transfers." |

MANUALLY OPENED REACTOR TRIP CIRCUIT BREAKERS TO INSERT CONTROL BANK "B"
"Manually opened reactor trip breakers in Mode 5 to insert control bank 'B' due to blown fuse in rod control cabinet."
Licensee was moving control rod bank "B" following I & C work, and the control rod bank failed to move as expected. All other control rod banks were inserted into the core at the time of the event. EDG's and offsite power sources are OPERABLE, and there is no increase in plant risk.
The licensee will inform the NRC Resident Inspector. |

AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGNS
"On October 21, 2008, Mississippi State Department of Health was notified by Rich Dailey, RSO for Wal-Mart that two (2) exit signs, each containing 11.5 Ci of H-3, were missing from the Wal-Mart store in Hernando, Mississippi. On October 27, 2008, DRH informed the RSO for Wal-Mart that the exit signs were exempt from state regulations but to send in a written notification report. The following devices were reported missing from Wal-Mart:
"1. Exit sign form store (#05419) located at 2600 McIngvale Road, Hernando, Mississippi 38632, Serial Number - Unknown, Manufacturer - Isolite, activity - 11.5 Ci of tritium at time of manufacture.
"2. Exit sign form store (#05419) located at 2600 McIngvale Road, Hernando, Mississippi 38632, Serial Number - Unknown, Manufacturer - Isolite, activity - 11.5 Ci of tritium at time of manufacture."
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. |

RECIRC LOOP TEMPERATURE ELEMENT FAILED
"On 11/3/08 at 0652 Shutdown Cooling (SDC) was lost on Dresden Unit 3 when the Recirc Loop Temperature Element (3-0260-13B) failed upscale. Unit 3 was in the process of initial cooldown for entry into a refueling outage. Actual Recirc loop temperature was about 217 degrees F based on alternate indications. The temperature element (3-0260-13B) remained upscale for several minutes before returning to its previous value. The failed element was jumpered out and SDC was restarted. This event is reportable under 10CFR 50.72(b)(3)(v)(B)"

MANUAL REACTOR TRIP DUE TO FEEDWATER REG VALVE FAILURE
"On 11/3/08 at 2322, Unit 2 was manually tripped due to the failure of Loop 4 Feed Water Reg. Valve (FRV Controller.). Manual control was attempted to control Level in Loop 4 Steam Generator (S/G); however, Loop 4 FRV failed to respond, A manual Reactor Trip was initiated as a result of this failure. In addition, Auxiliary Feedwater (AFW) initiated as required due to a Feedwater Isolation signal
"The Loop 4 FRV did isolate from the Feedwater Isolation signal.
"The Plant is being maintained in Mode 3 at NOT/NOP, 547 F and 2235 psig, with AFW supplying the S/G's and Steam Dumps removing decay heat.
"Additionally, Unit 2 has an indication of a primary leak inside lower containment. The leak rate is calculated to be approximately 2.0 gallons per minute. Based on current indications, the leak is suspected to be from a Pressurizer level transmitter
"No primary system or steam generator safety valves opened due to this trip. An investigation has been initiated to determine the cause of the Loop 4 feed Water Reg. Valve (FRV Controller) failure and the source of the approximately 2.0 gallons per minute primary leak. A recovery plan will be developed."
Pressurizer (PRZ) level is stable. All safety related systems are available and OPERABLE for safe plant shutdown. There is no impact on Unit 1. The loop 2 S/G blowdown sample line valve did not go closed as expected on the feedwater isolation signal. The licensee is taking action to isolate it.
The licensee notified the NRC Resident Inspector. |
