COLORADO AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGNS

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

"The general license section of the Radioactive Materials Program [at the Colorado Department of Public Health and Environment] sent out annual notifications requesting response regarding tritium exit signs reported in use at locations given by the manufacturer. Upon an audit of the annual mailing for non-responders, Elkco Properties & Olson's Greenhouse were contacted. After a complete inspection of the greenhouse and several confirmations, only 3 tritium exit signs remain in the facility. It is unknown as to the disposition of the lost 3 exit signs as further information is unavailable due to time of reporting loss. Elkco has plans to remove the existing signs and replace them with non-tritium signs. They will inspect each building they lease and should any tritium exit signs be found, follow the regulations in the Colorado Rules and Regulations Pertaining to Radiation Control.

"Event Description: Manufacturer; SRB Technologies, 3 exit signs are reported as lost, Model#; BX10WH, Serial number's; C12805, C12806, C12810; Isotope H-3 Tritium; Activity; 9.21 Ci, they were shipped from SRB Technologies on 10/23/2004.

"Event is completed/closed."

Colorado Event Report ID No.: CO17-0006.

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

AGREEMENT STATE REPORT - POTENTIAL CONTAMINATION EVENT

The State of Texas provided information on a potential contamination event at the Halliburton Energy Services facility in Houston, TX. An employee was working on a well logging tool that contained a 1.3 microCurie Cs-137 source. While removing the Cs-137 sealed source from the tool, an employee noticed a small hole in the Cs-137 capsule. The employee stopped working on the tool, cleared the area, and restricted access to the room where the work was being performed. Contamination swipes were taken in the area and sent to a third party laboratory for analysis. No over exposures were indicated. The initial survey of the worker identified a small area of one of his boots that had some contamination.

The following event retraction was received from the State of Texas via email:

"Initial information concerning this event was provided via telephone on 2/26/2017. However, after further evaluation of the information provided by the licensee, it has been determined that this event does not meet any reporting requirement."

Texas Incident #: 9467

SOURCE HOLDER STUCK OPEN

Licensee reported that they were in the process of removing a Kay-Ray Model # 7062B source holder from an installed position. The device serial number is #24093 with a Cs-137 10 mCi source. They believed the source holder to be closed during the removal operation. While in the process of removing the source holder from its installed location, they received unexpected radiation levels on their survey meter and laid the source holder on the room floor with the source pointing in the down direction. They then used some lead shielding to cover the source device and moved it to a storage location. The current radiation levels in the vicinity of the source holder are normal background. The licensee plans on reviewing the radiation dose information when personal dosimetry is processed at the end of the quarter (March 15, 2017). The licensee also plans on contacting Berthold Technologies for disposal of the device.

PLANNED ULTRASONIC TEST ON PREVIOUSLY REPAIRED REACTOR VESSEL PENETRATION DID NOT MEET ACCEPTANCE CRITERIA

"On 3/5/2017 at 0800 [CST], during the Byron Station Unit 1 refueling outage, it was determined that the results of a planned Ultrasonic (UT) examination performed on a previous repaired penetration of the reactor vessel head did not meet applicable acceptance criteria. These indications are not in the reactor coolant pressure boundary; however they are very near the previously repaired J-groove weld. The indication will be addressed prior to returning the vessel head to service. The examination was being performed to meet the requirements of 10 CFR 50.55a(g)(6)(ii)(D) and ASME Code Case N-729-1 to ensure the structural integrity of the reactor vessel head pressure boundary.

"This event is being reported under 10 CFR 50.72(b)(3)(ii)(A) for 'Any event or condition that results in the condition of the nuclear power plant, including its principal safety barriers, being seriously degraded.'

"The licensee has notified the NRC Resident Inspector.

"Exelon Generation Company, LLC is also notifying the NRC Division of Component Integrity or its successor, by use of this ENS Report, of changes in indication(s) or findings of new indications(s) in the penetration nozzle or J-groove weld beneath a seal weld repair, or new linear indications in the seal weld repair, prior to commencing repair activities."

* * * UPDATE PROVIDED BY CHARLES BERGER TO JEFF ROTTON AT 1750 EST ON 03/06/2017 * * *

"Byron Event Notification 52952, made on March 05, 2017, reported two indications on one reactor head penetration.

"On March 06, 2017, ultrasonic examination identified two additional indications on the same penetration nozzle, (P-76). Additionally, two indications were identified on a second penetration nozzle (P-74), and one indication was identified on a third penetration nozzle (P-77). The indications on these three penetrations are all of the same type and none are within the reactor vessel head pressure boundary.

"This event is being reported under 10 CFR 50.72(b)(3)(ii)(A) for 'Any event or condition that results in the condition of the nuclear power plant, including its principal safety barriers, being seriously degraded.'

"The NRC Resident Inspector has been notified.

"Exelon Generation Company, LLC is also notifying the NRC Division of Component Integrity or its successor, by use of this ENS Report, of changes in indication(s) or findings of new indications(s) in the penetration nozzle or J-groove weld beneath a seal weld repair, or new linear indications in the seal weld repair, prior to commencing repair activities."
