AGREEMENT STATE REPORT - LEVEL GAUGE CESIUM-137 SOURCE WOULD NOT RETRACT
The following information was provided via email:
"On April 9, 2009, at 19:21 the Agency [state] received a phone call from the Radiation Safety Officer (RSO) at Flint Hills Resources in Odessa Texas. The RSO reported that a 300 millicurie (120 mCi calculated) Cesium (Cs) -137 source used in an Ohmart\VEGA model # SHLM level gauge would not fully retract into the source holder. The gauge is installed on the side of a [chemical] reactor vessel. The source will retract to the sleeve between the vessel and the gauge housing, but will not go into the gauge. The source is currently fully inserted into the vessel. Dose rates in the area are normal. No additional exposure was received by individuals at the facility. Management will meet on April 10, 2009, to determine how to address the source retrieval. The gauge was to be removed from the vessel for disposal by the manufacturer. The licensee will provide additional information next week. A similar event occurred at this facility in October, 2008 (EN44543)."

OPTIONAL 60-DAY TELEPHONE REPORT OF AN INVALID START OF ALL FOUR EMERGENCY DIESEL GENERATORS
"This report is being made under 50.73(a)(2)(iv)(A).
"At the time of the event, Unit 1 was Defueled/No Mode and Unit 2 was 100% Power/Mode 1.
"On 04/9/09 @ 0115 an invalid start of the four emergency diesel generators occurred. The actuation was caused by inadvertent actuation of the K609 relay. The K609 relay causes an emergency start of the diesel generators on a SI [Safety Injection] signal. The actuation of the K609 relay was caused by technicians inadvertently depressing the K609 relay latch pushbutton while working on a nearby K604 relay. The K609 relay is located just below the K604 relay in the same SSPS [Solid State Protection System] panel.
"The train actuated was both Train A and Train B for both Units 1 and 2. The system actuated was the emergency diesel generators. Complete train actuation occurred. The emergency diesel generators started successfully."
The licensee has notified the NRC Resident Inspector.
