TECHNICAL SUPPORT CENTER VENTILATION SYSTEM OUT OF SERVICE
"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.
Informed R4DO (Spitzberg).

UNUSUAL EVENT DECLARED DUE TO AN IDENTIFIED LEAKAGE EXCEEDING 25 GALLONS PER MINUTE
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."
Notified R4DO (Spitzberg), NRR EO (Nelson), and IRD (Marshall).
* * * RETRACTION ON 4/20/10 AT 1417 EDT FROM DAVID HURT TO R. ALEXANDER * * *
"The declaration of Unusual Event SU6.1, RCS leakage, on 4/13/10 is being retracted, because the declaration was inaccurate. The leak was an isolable intersystem leak of the CVCS, not RCS leakage, and the leak was stopped within the 15 minute time period allowed to determine EAL applicability. Therefore, the leakage did not meet the Initiating Condition for the EAL.
"The NRC Resident Inspectors have been notified."

AGREEMENT STATE REPORT - UNCONTROLLED CONTAMINATION EVENT
On April 13, 2010, a student at the Georgia Institute of Technology (the licensee), under the supervision of an authorized user, was conducting an electroplating experiment, using Ni-63, under a fume hood in one of the licensee's RAM (Radioactive Material) rooms. During the experiment, the student noticed fumes outside the hood and ceased the experiment. She took a swipe outside the hood and found no contamination.
On April 14, the licensee's Radiation Safety Officer took swipes of the room and found 22,000 DPM of contamination on the fume hood lip, 11,000 DPM on the RAM room floor, 1,200 DPM on a public hallway floor outside the RAM room, and contamination in an adjacent RAM room. All areas have been cordoned off to control access and cleanup is in progress.
It is unknown whether the student had any uptake, was overexposed, or was contaminated during the event.
