AGREEMENT STATE REPORT - SHUTTERS FOUND THAT WERE DIFFICULT TO OPERATE ON TWO PROCESS GAUGES

The following was received from the State of Louisiana via facsimile:

"On 4/22/2013, the Radiation Safety Officer (RSO) for ExxonMobile Chemical was performing his annual inventory and operational checks on the level gauges at the Baton Rouge facility. During the checks, two level gauges were found with shutters that were difficult to operate.

"The gauges detected were Ronan Engineering Gauges, devices involved, Model Number SAF-F37. One gauge is S/N 0781GK loaded with 100 mCi of Cs-137 and S/N 4585GH loaded with 25 mCi of Cs-137. Ronan Engineering has been contacted to fix the problem or repair the gauge. These gauges are installed on process and pose no safety threat to the general public or the employees. This is not considered a safety equipment failure, just being installed on a process in a very harsh corrosive environment.

"This is a two shutter malfunction on level gauges installed on processes. These devices do not pose a radiation exposure threat to the general public. They will remain in operation on the process until and after repair.

"The department considers this event closed."

AGREEMENT STATE REPORT - RADIOGRAPHY SOURCE FAILS TO RETRACT

The following information was received via fax:

"On 04/26/2013, the RSO for IRIS, was notified by one of his radiography crews working at the Marathon Refinery that a source was not retracting into the shielded area of the camera.

"This incident involved a QSA Global Exposure Device, Model Delta 880, S/N D6458, loaded with an Ir-192 source. Associated equipment was used with the exposure device. The problem occurred when the crew used a magnetic source tube stand as opposed to a non-magnetic support stand.

"Source retrieval was accomplished by the RSO around 2:53 pm. Using safety equipment, maintaining a 2 mR boundary, and time, the highest exposure received was by the RSO which was 75 mR. The other exposures recorded were from normal work activities. The Department [Louisiana Department of Environmental Quality] was notified after source retrieval was completed."

AREA ACCESS RESTRICTED FOR MORE THAN 24 HOURS DUE TO INCREASED RADIOLOGICAL CONTROLS

"On 04/30/13, while changing the feed from Position 3 East to Position 3 West autoclaves, Operators noticed a pressure spike on the 3 East cylinder to approximately 47 psia. After disconnecting the cylinder in Position 3 East with Health Physics (HP) assistance, HP found a contamination spread on the cylinder, on the grating within the autoclave, and on the autoclave locking ring. Due to the contamination spread, access requirements to the area will be increased for more than 24 hours. Decontamination efforts are underway but will not be completed within 24 hours from the time that radiological controls were increased.

"This event is reportable as a 24 hour event in accordance with 10 CFR 76.120(c)(1)(i) 'An unplanned contamination event that: Requires access to the contaminated area, by workers or the public, to be restricted for more than 24 hours by imposing additional radiological controls or by prohibiting entry into the area.'

"The NRC Resident Inspector has been notified of this event."

MAIN ANNUNCIATOR SYSTEM INOPERABLE DUE TO MAINTENANCE

"On May 8, 2013 at 1700 hours with the reactor in a Cold Shutdown condition and the Reactor Mode Select Switch in Refuel, the main control room annunciator system became inoperable during a preplanned activity to repair the associated 120VAC/125 VDC instrument power supply transfer switching scheme. The reactor cavity is flooded, the fuel pool gates are removed, shutdown cooling is in service and reactor vessel reassembly activities are in progress. The appropriate abnormal procedure was entered and compensatory actions including periodic monitoring of bus voltages and field annunciator panels were implemented for systems in service at the time of the loss. Station risk is green and all key safety functions are green. Troubleshooting is in progress however return to service time has not been determined.

"This notification is being made in accordance with 10 CFR 50.72(b)(3)(xiii). The USNRC Resident Inspector has been notified. This event has no impact on the health and safety of the public."
