AGREEMENT STATE REPORT - MISSING FIXED GAUGE SHUTTER

The following report was received via e-mail:

"On 02/26/2015, the RSO for Boise Cascade called in a preliminary report [to the Louisiana Department of Environmental Quality] about a shutter missing on a gauge to be 'locked out' during a 24 hour turn-a-round. The shutter is a manual sliding port cover that has to be removed when the gauge is used on the process. The removed shutter is stored by placing it on an adjacent surface until needed. Vibrations on the process had caused the port cover to fall approximately 50 ft. below the storage locations. However, this time the cover could not be located and the gauge could not be locked out. The gauge remained on the process until it could be repaired.

"On 02/26/2015, a replacement shutter/port cover was ordered from Thermo Measuretech. The shutter was delivered on 02/27/2015 and installed the same day. There was no radiation exposure risk to the public or workers. The gauge is installed on a 50 ft. elevation and the unshielded radiation field is approximately 0.3 mR/hr at 1 ft. from the surface of the device.

"The gauge was a Texas Nuclear Device, TN 5192, s/n B3421 containing approximately 100 mCi of Cs-137 when installed during the mid-1980s.

"The Department [Louisiana Department of Environmental Quality] considers this item closed and the records will be reviewed during the next inspection."

AGREEMENT STATE REPORT - RADIATION TECHNICIAN POTENTIAL OVEREXPOSURE

The following information was obtained from the State of Florida via email:

"An employee of Cardinal Health had a dosimeter reading of 140 REM. The employee routinely wears one whole-body badge and two ring dosimeters assigned to him. These findings are for the wear period of 2/16/2015-3/1/2015. The whole body badge had a reported dose of 140884 mRem DDE and 241488 mRem SDE. [Cardinal Health] stated that the individual didn't have any reportable readings from their rings badges for this wear period. The individual is showing no symptoms of overexposure and has been removed from handling radioactive material as a safety precaution. It is believed that the badge may have become contaminated therefore distorting the correct exposure reading. Cardinal Health is reportedly conducting an investigation to find the cause and extent of this incident. Pending the Landauer report and some additional information, an investigator will be assigned to inspect their laboratory for safety and confirm Cardinal Health's investigative conclusions."

AGREEMENT STATE REPORT - FIXED GAUGE SHUTTER WOULD NOT CLOSE PROPERLY

The following information was received via fax:

"On 03/17/2015, the RSO for MOTIVA ENTERPRISES called in a preliminary report about a shutter that would not close properly on a gauge installed on a process. The shutter could not be closed or locked out. This situation reoccurs periodically due to the corrosive operating environment of this gauge or device. Routine maintenance was performed by BBP Sales and the device again functioned as designed.

"This situation is reoccurring about every 11 to 14 months. The corrosive and caloric operating environment is the source of this operational problem. The problem with the shutter function is corrected by cleaning and lubricating the mechanism. The equipment/source holder is not broken, just in need of preventive maintenance.

"There was no removable radiation detected in the leak test results and the rotor moved freely when the top plate was removed for the maintenance. BBP Sales was called to perform the maintenance to correct the problem. The gauge/source holder was 'fixed.' The repairman/technician was never exposed to a radiation field greater than 3.0 mR/hr.

"The Department [Louisiana Department of Environmental Quality] considers this item closed and the records will be reviewed during the next inspection."

Gauge is an Ohmart Vega S/N 3211CO with a 175 Ci Cs-137 source.

AGREEMENT STATE REPORT - EXTREMITY OVEREXPOSURE WHILE OPERATING A RADIOGRAPHY CAMERA

The following report was received from the Texas Department of State Health Services via email:

"On March 25, 2015, the licensee reported that on March 15, 2015, one of its industrial radiographer trainees had experienced a possible overexposure to his right hand while using a QSA Model 880 camera that contained a 54.5 curie iridium-192 source. Initial information reported by the licensee: Following the 10th and final exposure of the day, the radiographer trainee climbed a ladder to the first deck and approached the camera from the rear with a survey meter. He performed a 360 degree survey of the camera and full length of the guide tube noting a zero reading on the survey meter. He then attempted to disconnect the guide tube by attempting to rotate the outlet port cover. When it would not rotate, he looked at the back of the camera to ensure the selector was in the correct position, and then attempted to disconnect the guide tube a second time. Again, the outlet port cover would not rotate and he looked at the back of the camera and noticed the slide bar of the lock was showing red, indicating the source was not in the fully shielded and secure position. He climbed down the ladder and informed the radiographer trainer what had happened.

"The radiographer trainer exposed the source approximately 1/4 turn and forcibly retracted it to its fully locked and shielded position. They checked the survey meter (battery function check) and determined it was not working properly. The meter was disassembled, battery terminals were adjusted, and the meter functioned properly.

"The radiographer trainer surveyed the camera and determined the source was fully retracted. The radiographer trainee stated he did not hear his alarming rate meter due to the noise level at the job site. The radiographer trainer did not receive any additional exposure as a result of this event. The radiographer trainee's pocket dosimeter was off-scale. His dosimetry badge was sent for processing and from the results the licensee determined he had received 384 millirem whole body dose from this event. Calculations will be made following a re-enactment of the event on 03/30/2015 to determine the dose to his hand.

"Exposure Device: QSA Model 880D SN: D1123, Source: 54.5 curies iridium-192 SN: 14191G"

The State of Texas is continuing to investigate the issue.

LOSS OF EMERGENCY OPERATING FACILITY ELECTRICAL POWER AND PHONE SYSTEM

"At 1210 CDT the transformer supplying power to the Emergency Operating Facility (EOF) stopped working due to the failure of a capacitor bank. The EOF is located adjacent to OPPD's [Omaha Public Power District] North Omaha facility, approximately 17 miles south of Fort Calhoun Station. The event caused a small grass fire which was quickly extinguished. The local fire department was called. The backup emergency diesel generator for the EOF started and supplied power to the facility, as designed. With the EOF diesel operating, the facility is able to function as required during emergency conditions.

"At 1440 CDT the EOF emergency diesel generator stopped running. At 1545 CDT the Conference Operations (COP) network phone system failed. The COP network is the primary emergency notification system between OPPD, state and county agencies. It is used to provide initial and updated notifications and for general information flow between these agencies. Alternate means of communication have been established (commercial lines) and a dedicated communicator is stationed in the control room to ensure that we can facilitate communication should the need arise.

"Power to the EOF was restored at 1713 CDT. At time 1720 CDT the COP tested as normal."

The licensee notified the NRC Resident Inspector.
