| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT - LOSS OF TRAINING BUTTON SOURCE
The following information was received via fax:
"A Training button source was lost on 3/6/2010 during training in Alachua county. The training facility was searched and the source was not found. Corrective actions include additional source handling procedures, daily checklists for use of sources, and training on proper notification to RSO of all events regarding use of RAM. No further action will be taken on this incident."
Florida Incident Number: FL10-049
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. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf
This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source |

| Event Text AGREEMENT STATE REPORT - POTENTIAL RADIOGRAPHER OVEREXPOSURE
The following information was received via fax:
"An employee's TLD recorded an overexposure of 6.8 rem. The date was 22 March 2010 when the overexposure occurred. The affected employee claims he left his leather pouch with the TLD [in it] in the exposure area for two shots. His pocket dosimeter reading was also off scale. The RSO originally calculated the employee's dose to be approximately 4 rem which is not required to be reported to the state. The RSO received Landauer's dosimeter report sometime after 22 Mar 2010 which showed a 6.8 rem dose. The licensee contacted Licensing and Materials on 7 April 2010. The Tampa Inspection Office will investigate." |

| Event Text RADIOGRAPHY CAMERA SOURCE NOT FULLY RETRACTED
The following information was received via email:
"Radiographer failed to fully retract Se-75 source into QSA Model 880 camera while on a job site in Stratton, Ohio. No additional information regarding device or source is available at this time.
"Radiographer did not 'bump check' the source after retraction to make sure that the source was locked in the camera. He stated that he was using a survey meter as he approached the camera, but it slipped from his hand during his approach and fell to the ground. He stated that he did not verify proper operation after picking up the meter. He was approaching the camera from the rear and stated that he had not observed any reading on the meter. As the radiographer disconnected the guide tube, he noted that the source cable was still sticking out of the camera with the source. He stated that he turned the crank handle about 3/4 of a turn, at which time the source was retracted. The radiographer stated that he could not hear his alarming rate meter due to loud noise in the power plant where the work was being done. The radiographers pocket dosimeter (0 - 200 Mr) was reported as having gone off-scale.
"The licensee has estimated a whole body exposure of 1.8 R and an extremity dose to the radiographer's hand of between 3 R and 20 R. The licensee has shipped the radiographer's dosimeter for rush processing and expects to have results late Monday (4/12/10) or Tuesday. ODH [Ohio Department of Health] will conduct an investigation.
"NOTE: This report is being made as a precaution until the actual dose received by the radiographer is confirmed."

"This report is being made under 10CFR50.73(a)(2)(iv)(B)(2). On February 23, 2010 at 1050 EST procedure 52PM-C71-001-0, RPS M/G Set System Preventative Maintenance, was being performed. During restoration of RPS Buses on Unit 1, only the Unit 1 required logic was reset. The Unit 2 logic was also required to be reset but was not. Procedure 52PM-C71-001-0, RPS M/G Set System Preventive Maintenance, did not clearly require the reset of both Unit 1 and Unit 2 logic. The procedure has been revised to make this requirement clear. Continuation of steps in the procedure required links to be closed which resulted in SBGT starting on Unit 1 and Unit 2 from Unit 2 logic. Unit 1 and Unit 2 Reactor Building ventilation isolated. This was not due to a valid signal. The automatic actuation of the standby gas treatment system (SBGT) and the isolation of Unit 1 and 2 secondary containment isolation dampers is considered an invalid actuation since the parameters that cause this actuation to occur had not been exceeded. For this reason the actuation is considered invalid and a report to the NRC is not required by 10CFR50.72(b)(3)(iv); however, because the secondary containment isolation signals affected containment isolation valves in more than one system (Unit 1 and 2 components affected) the event is reportable as required by 10CFR50.73(a)(2)(iv)(B)(2). A licensee event report (LER) is required, but can be a telephone notification as allowed by 10CFR50.73. In the case of an invalid actuation reported under 10CFR50.73(a)(2)(iv), other than actuation of the reactor protection system (RPS) when the reactor is critical, the licensee may, at its option, provide a telephone notification to the NRC Operations Center within 60 days after discovery of the event instead of submitting a written LER.
"The four Standby Gas Treatment (SBGT) fans auto started and both Unit 1 and Unit 2 reactor building and refueling floor normal ventilation systems automatically shutdown and isolated. The SBGT Initiation and the ventilation system shutdown were both complete actuations."
The licensee notified the NRC Resident Inspector. |

"During routine testing of the Technical Support Center (TSC) ventilation system, the charcoal filter emergency supply fan did not start as required. As a result, under certain accident conditions, the TSC may become uninhabitable because of the inability of the charcoal filtration unit to maintain environmental conditions within limits.
"If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures unless the TSC becomes uninhabitable due to radiological or other conditions. If relocation of the TSC becomes necessary, Operational Support Center (OSC) and TSC personnel will relocate to an alternate TSC location in accordance with applicable site procedures with primary TSC and OSC positions reporting to the Main Control Room (which is capable of supporting the additional personnel).
"This notification is being made in accordance with 10CFR50.72(b)(3)(xiii) due to the potential loss of an Emergency Response Facility (ERF).
"Troubleshooting is in progress to determine the cause of the equipment failure. An update will be provided once the TSC ventilation has been restored to normal operation.
"The NRC Resident Inspector has been notified."
* * * UPDATE FROM TIM GATES TO CHARLES TEAL ON 1742 EDT 4/13/10 * * *
The failure of the fan to start was caused by loose linkages for a limit switch. The problem has been repaired and the TSC has been returned to service.
The NRC Resident Inspector has been informed.

On April 13, 2010 at 1200 CDT, Callaway Unit 1 declared an Unusual Event due to identified leakage of greater than 25 gallons per minute (EAL SU6.1). During the flushing of the 'A' Chemical and Volume Control System mixed bed demineralizer, a leak occurred from the vent valve exceeding 25 gallons per minute for approximately 5 minutes. The leak was isolated and the Unusual Event was terminated at 1223 CDT. No personnel contamination or outside release occurred.
The licensee has notified the State and local authorities and the NRC Resident Inspector.

"Callaway Plant declared an Unusual Event at 1200 CDT on 4/13/2010. The cause of the event was Emergency Action Level (EAL) SU6.1, identified leakage greater than 25 gallons per minute (gpm).
"When attempting to place the 'A' Chemical and Volume Control System (CVCS) mixed bed demineralizers in service, a drop in the Volume Control Tank (VCT) level was noted by the Reactor Operator (RO). Technical Specification (TS) 3.4.13 Condition A was entered at 1033 CDT upon identification of identified leakage of the Reactor Coolant System (RCS) greater than 10 gpm.
"TS 3.4.13 Condition A requires reduction of leakage to limits within 4 hours. The leakage was verified to be stopped at 1038 CDT, at which time TS 3.4.13.A was exited. The system was restored to a normal alignment.
"Upon review, it was determined that the VCT level dropped approximately 125 gallons in 5 minutes. EAL SU6.1 was declared at 1200 CDT and closed at 1223 CDT.
"The state and local counties (Callaway, Gasconade, Montgomery, and Osage) were notified of the event at 1210 CDT and of the event closeout at 1227 CDT.
"The NRC Resident Inspector was notified of the event. A news release will be made by Ameren Corporate Communications."
