Following Agreement State Report was received via e-mail
"Description of Incident: DRH received notification on 1-28-07 from Mississippi Emergency Management Agency (MEMA) about a Troxler Model 3411 M/D gauge, Serial # 9533, that had been reported stolen. The gauge belonged to Aquaterra Engineering. The RSO was contacted and he stated that the gauge had been locked in a tool box. The tool box was not big enough to put the shipping container in it also, so the shipping container was in the bed of the truck. The RSO stated that the lock was cut on the tool box allowing the gauge to be removed. He also stated that the gauge's source rod was locked. Issued press release on 1-29-07.
"Date of Incident: Sometime between 1-26-07 and 1-28-07
"Isotope(s): Cesium-137, 8 millicuries; & Americium-241:Be, 40 millicuries.
"Describe clean-up actions taken by DRH: None required.
"List any other actions required of DRH: Licensee will be required to send a written report of stolen gauge within 30 days.
"List any actions taken to notify NRC, other Agreement States: Notified Meridian, MS, Police Department. Notified Lauderdale County Emergency Management. Notified NRC by E-mail. Notified Alabama Radiation Control by phone. Mississippi Department of Health issued press release.

"Record of incident in RAM files: Yes
"Enforcement action taken: Investigation ongoing."

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. |

"On 1/29/07 with Hope Creek reactor startup in progress, in mode 1 at 22% Reactor power, Secondary Condensate Pump Minimum Flow Control Valves began to cycle. Reactor water level reached 39" (RPV level 7) and then lowered to 30" (RPV level 4). Manual control of the Reactor Feed pumps was taken, however, RPV water level continued to lower to 15" (Reactor scram on RPV water level is 12.5") at which time the reactor mode switch was locked in shutdown. There were no ECCS injections and all ECCS systems are operable. Initial review of the event indicates that all systems operated as expected with the exception of the Secondary Condensate pump minimum flow valves and the 'A' IRM failed to insert. Current plant conditions as of 1/30/07 at 0010 are: Hope Creek is in mode 3 at 565 psig. The Main Steam Line Isolation valves are open. 'B' and 'C' Primary Condensate Pumps, 'B' and 'C' Secondary Condensate Pumps, and 'A' Rx Feed Pump are feeding the vessel. All control rods have fully inserted on the scram and Main Turbine Bypass valves are removing decay heat."
The licensee will inform the LAC (Lower Alloways Creek Township) and has informed the NRC Resident Inspector.

"Based on the post-trip review performed by the licensee, it was determined that the in-service Reactor Feed Pump Minimum Flow Recirculation Valve opened in response to the feed flow adjustments. Reactor vessel level reached the low-level trip set point and an automatic reactor scram occurred. During the event analysis it was determined that the operator initiated the manual scram two seconds after the automatic low level scram occurred. A post event equipment performance review concluded that the Secondary Condensate Pump Minimum Flow Recirculation Valves operated as expected."
The licensee notified the NRC Resident Inspector. The R1DO (Cahill) notified. |

"Due to a procedure based line-up of the Penetration Recirculation Filtration (PRF) system, it has been discovered that the system is placed in a configuration that could prevent it from performing its safety function. The PRF System filters airborne radioactive particulates from the area of the fuel pool following a fuel handling accident or ECCS pump rooms and penetration area of the Auxiliary Building following a loss of coolant accident (LOCA). The PRF system is a standby system that upon a receipt of an actuating Engineering Safety Feature Actuation System signal or upon receipt of a high radiation signal or a low air flow signal from the normal spent fuel pool room ventilation system will start the PRF fans and discharge the ventilation air stream through the system's filters.
"The standard operating procedure for the PRF system directs the control room staff to place the system in a 'full recirculation' mode of operation following a design bases LOCA if the system can maintain a proper vacuum inside the PRF boundary. The 'full recirculation' mode of operation isolates the Recirculation fan discharge to the atmosphere and fully opens the Recirculation fan recirculation damper. This mode of operation is only an additional defense in depth measure and is not credited in the accident analysis. In this mode of operation, it has been discovered that a degraded PRF boundary which allows in leakage into the boundary which is less than the maximum allowable operational limits, could place the system in a configuration that might cause the Exhaust fan to trip. The trip is caused by an overload condition at the supply breaker due to the increased flow of the Exhaust fan to the atmosphere. With the Recirculation fan discharge isolated to the atmosphere and the Exhaust fan inoperable, the PRF system may not establish an adequate vacuum in the PRF boundary during a Post LOCA accident, thus not meeting its design function.
"This condition was discovered on Unit 1, A train PRF system. Since the systems are similar between Units 1 and 2, and the procedure guidance is exactly the same for the 'full recirculation' mode of operation, this condition has the potential to affect both units, both trains of PRF.
"Corrective actions have been completed to eliminate this mode of operation from the procedure guidance given to the control room staff for operation. A major contributor to the in leakage into the PRF boundary on Unit 1 has also been repaired which reduced the running load on the Exhaust fan for that train. With the procedure guidance removed, the system should not be placed in a 'full recirculation' mode of operation, thus eliminating the potential for a failure of the designed safety function of the system."
The licensee notified the NRC Resident Inspector. |
