The following information was received from the Arkansas Department of Health via email:
"The University of Arkansas (U of A), Arkansas Radioactive Materials Licensee Number ARK-0064-01120, notified the Arkansas Department of Health, Radioactive Materials Program, via e-mail on Thursday, January 15, 2015 at 1400 hours, of the following labeled items found in the public domain (private home): (1) UO2 (3% U-235) in a small glass vial with lid and (2) U-235 in a medium size glass jar with lid. The isotopes and weights of these items will be identified and/or confirmed once in State possession.
"The U of A's Radiation Safety Officer reported exposure readings of item (1), listed above, at '2 mR/hr' and stated item (2), listed above, 'did not produce any readable dose.' The Radiation Safety Officer also performed swipe tests and surveys for contamination.
"The State requested the U of A to take immediate possession, properly store and secure the items. The State will retrieve these items promptly, which will be properly secured and stored at the State's authorized storage location.
"It is unknown at this time if there has been any exposure(s) to the public. The State is awaiting a written report from the licensee and will continue to investigate this event. The State will update this event as more information becomes available."

| Event Text AGREEMENT STATE REPORT - STUCK SOURCE IN RADIOGRAPHY CAMERA
The following information was received via E-mail:
"This event occurred at a permanent shooting cell at the licensee's facility in Amite LA.
"The RSO was performing the semi-annual leak test on his radiography cameras. One is loaded for use in radiography and the other is essentially considered in storage. He removed the guide tube to swab the port entry and finished the paperwork for the leak test. Later he went to make an exposure and the source extended the length of the drive cable and would not retract into the shielded position. The source was stuck out into the vault shooting bay area.
"The equipment was an Amersham Model 680-BE, s/n BE 178 loaded with approximately 50 Ci of Co-60, a QSA Global source s/n 45274B. The associated equipment was an Amertest Automatic Exposure Control, Model 957, s/n 67.
"This was operator error. The RSO did not reattach the guide tube after performing a leak test at the camera's port. The source was being utilized in a fixed shooting cell/vault when it would not retract.
"[In order to retrieve the source] the side panel was removed from the camera and a manual source retraction was performed. The source was shielded from unnecessary exposure, ALARA [as low as reasonably achievable], during the source retrieval. Again, this was operator error, not equipment failure.
"The source is secure from removal and unnecessary exposure. This event is not closed and additional investigation and evaluation will continue. The source is in a safe shielded position and no threat to workers or the general public."

"At 0355 [CST] on Monday, January 26, 2015, the Dresden Nuclear Power Station (DNPS) Technical Support Center (TSC) emergency ventilation system was removed from service for planned preventative maintenance activities on the TSC air handling unit, air compressor units, and TSC air filtration unit. During the maintenance, the TSC Ventilation will be shut down. 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 38 hours. Contingency plans are in place so that if an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing Emergency Planning (EP) procedures and checklists. If radiological or environmental conditions require TSC facility evacuation during ventilation system restoration; the Station Emergency Director will evacuate and relocate the TSC staff in accordance with station procedures.
"The NRC Resident Inspector has been notified." |

Normal and High Range Ventilation Process Radiation Monitors (3HVR*RE10A/B) were removed from service due to low process flow affecting sample flow. The cause of the low process flow is unknown and under investigation at this time. Maintenance was performed yesterday, 1/26/15, including a successful calibration.
Action taken includes placing temporary sampling in service and estimating process flow. A priority one work package has been issued with repairs in progress.
The licensee informed the State of Connecticut, Waterford Township Police and the NRC Resident Inspector. | |
