AGREEMENT STATE REPORT - SOURCE DISCONNECT
The following information was received via E-mail:
"On June 16, 2013, the licensee reported to the Agency [Texas Department of State Health Services] they had experienced a source disconnect on June 15, 2013. The radiography team cranked the Iridium-192 source out of the Delta 880 camera for the first shot of the day and then they were unable to retrieve the source back into the camera. The source retrieval was performed by authorized persons. From initial reports, using pocket dosimeters readings, the largest whole body dose received was 195 mrem. Dosimetry badges have been sent for processing. The licensee is investigating the cause of the disconnect and will send the equipment to the manufacturer/service company for evaluation. No member of the general public received any dose from this event. More information will be provided as it becomes available, per SA 300."

DIVISION 1 AND 2 EMERGENCY DIESEL GENERATORS POWER BUSES AFTER MOMENTARY OFFSITE POWER LOSS
"Columbia Generating Station is shutdown for a refueling outage and is currently in Mode 4. At 1222 PDT June 15, 2013, the 115 kV offsite power to the backup transformer relayed off and then came back on. Both Division 1 and Division 2 4.16 kV critical switchgear buses were powered from the backup transformer at the time of the loss of backup power.
"Upon detection of under voltage conditions, Emergency Diesel Generators 1 and 2 started and powered the Division 1 and Division 2 4.16 kV critical switchgear buses after approximately 5 seconds. The temporary loss of power to the Division 1 and Division 2 4.16 kV critical switchgear buses also resulted in the closure of containment isolation valves in the Reactor Water Cleanup System, Equipment Drain System and the Floor Drain System. Shutdown cooling had previously been secured in preparation of performing the reactor pressure vessel hydro test. Investigation into the cause of the temporary loss of the 115 kV offsite power is on-going.
"The Division 1 and Division 2 4.16 kV critical switchgear buses are currently being powered from the 230 kV offsite power through the startup transformer.
"There were no radiological releases as a result of this event."
The licensee notified the NRC Resident Inspector.
