| Event Text AGREEMENT STATE REPORT - FIXED GAUGE STUCK SHUTTER
The following information was received via e-mail:
"The Plant Manager called the [Illinois Emergency Management] Agency to advise that a shutter on a gauge had failed. When staff went to close the shutter, [while performing] work in the immediate vicinity, the handle used to close the shutter, 'twisted off'. The shutter remained stuck in the open position. Radiation levels near the gauge did not change from the previous configuration. The area was posted to warn of the hazard and system maintenance personnel changed work procedures to account for the failure. No work is scheduled to be completed within the beam fan area in the lower portion of the vessel.
"The company's radiation safety officer confirmed the steps taken and applied additional shielding to the front of the gauge to effectively render the gauge 'off' until such time as the vessel is once again filled with product to reduce the radiation levels or the manufacturer can be on-site. Current weather predictions are such that it may be a couple of days until a field engineer can be dispatched to the site.
"This item remains open and may be further investigated depending on response by the manufacturer. This device experienced similar problems in October of 2009 which were addressed by the manufacturer. In that case, the gauge was 'upgraded' to include additional seals and replacement of others to prevent the infiltration of water which lead to corrosion of the shutter causing it to 'stick' in the open position unless sufficient force was applied to the handle."
The fixed gauge was manufactured by Ohmart Corp.; model number SH-F2; serial number 74932. The sealed source radionuclide is CS-137 with an activity of .08 Ci (2.96 GBq).

| Event Text AGREEMENT STATE REPORT - RADIOGRAPHY CAMERA SOURCE FAILED TO FULLY RETRACT
"On February 9, 2010, the Agency [Texas Department of Health] was notified by the licensee that while performing radiography with a 22 curie Iridium (Ir)-192 source, the source could not be retracted into the camera. The device is an Amersham 660B camera. The radiographer noted that when he returned the source to the camera, the auto locking mechanism failed to activate. The radiographer then cranked the source back out and tried again to locked the source in the camera. The locking mechanism failed to lock. The source drive cable was left in the position where the source should be shielded. The radiographer performed a dose rate survey on the guide tube. He found the dose rates near the end of the guide tube were elevated. He contacted his Radiation Safety Officer. An individual listed on the license to perform source retrieval went to the location and retrieved the source. No over exposures were reported. An inspection of the source pig tail and drive cable found that the connection of the drive cable to the source pig tail failed because the ball on the drive cable side of the connection had broken off from the drive cable." |

"On Thursday, February 11, 2010, the Limerick Technical Support Center (TSC) emergency ventilation system will be removed from service for planned preventative maintenance activities on the damper flow controller and air filtration charcoal system. During the maintenance, the non-emergency ventilation system will be functional. The TSC air filtration fan and dampers will be non-functional, rendering the TSC HVAC accident mode non-functional. This maintenance is scheduled to minimize out of service time. The planned TSC ventilation outage is scheduled to be completed within 12 hours. If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing EP [Emergency Planning] procedures and checklists. If radiological conditions require TSC facility evacuation during ventilation system restoration, the Station Emergency Director will evacuate and relocate the TSC staff in accordance with applicable site procedures."
The licensee has notified the NRC Resident Inspector.
