| Event Text AGREEMENT STATE REPORT - SHUTTER FOUND STUCK CLOSED ON PROCESS GAUGE
During the semi-annual inspection of the gasification facility's process gauges, a gauge was found with its shutter stuck closed. The gauge had not been used since the last licensee inspection so there would have been no indication from operation of the facility that there was a problem. The gauge was a Berthold Model P-2608-100 containing a 5 millicurie Co-60 source. The licensee has determined that the gauge is not really needed to support the process and has contacted Berthold to come to the facility and remove the gauge and take possession of it. The licensee has inactivated the gauge and, with the shutter stuck closed, considers that there is no risk to personnel. |

"On the morning of 03/04/2010, approximately 500 dead European starlings were found in the area surrounding the north part of the Turbine Building. Most of the dead birds were found around the main transformers. External examination of the dead starlings initially indicates the birds likely died from respiratory distress as a result of damage to their respiratory system. Initial indications are that the birds were somehow poisoned offsite, came to Wolf Creek to roost, and subsequently died while roosting.
"Wolf Creek notified the Kansas Department of Wildlife and Parks and the U.S. Fish and Wildlife Service of this event. This is being reported per 10 CFR 50.72(b)(2)(xi) since Wolf Creek made a notification to other government agencies.
"The Senior Resident Inspector was notified of this event."
* * * UPDATE FROM LANCE LANE TO HOWIE CROUCH @ 1904 EST ON 3/4/10 * * *
"Wolf Creek was informed that a bait/poison was applied under permit (USDA & USFWS) at a local dairy farm near Westphalia, KS. Poison was placed on Tuesday, which coincides with some birds in a weakened state Tuesday night and major die off Wednesday. The USDA has agreed to let Wolf Creek know if similar baiting is done in the future."
The licensee will be notifying the NRC Resident Inspector. Notified R3DO (Giessner). |

| Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | | 1 | N | N | 0 | Hot Shutdown | 0 | Hot Shutdown | Event Text SPECIFIED SYSTEM ACTUATION - FEEDWATER ISOLATION DUE TO HIGH STEAM GENERATOR WATER LEVEL
"A Turbine trip and Feedwater Isolation Signal was generated as a result of high level in 'A' Steam Generator. At approximately 0007 CST, a turbine trip and Feedwater Isolation Signal was generated when the level in the 'A' Steam Generator exceeded the initiation set point of 78%. Steam Generator level returned below the initiation setpoint at approximately 0008 CST. Steam Generator 'A' high level resulted from swell of the Steam Generator after opening the 'A' Main Steam Isolation Valve. Level was approximately 50% prior to the event and returned to approximately 50% within one minute.
"The turbine was already in the tripped condition due to the plant trip that occurred at 1458 CST on 03/02/2010 (Reference EN# 45739).
"Steam Generators are being fed with the motor driven startup Feedwater pump. Decay heat removal is via the Steam Generator Atmospheric Relief Valves and steam dumps. The plant is in Mode 4 with Reactor Coolant System pressure at approximately 500 psig and temperature at approximately 332 degrees F.
"Two Main Feedwater isolation valves did not fully close but the actuators were being supplied with auxiliary medium (air) at the time of the actuation. Feedwater isolation valves are not required to be operable in Mode 4."
The licensee will notify the NRC Resident Inspector. | |
