EN Revision Text: AGREEMENT STATE REPORT - STOLEN GAUGE

The following information was received from the Arizona Department of Health Services (the Department) via email:

"The Department received notification from the licensee that a portable gauge was stolen. A technician locked a portable gauge in the back of a truck and the truck was locked inside the users garage at their home overnight. When the gauge user came out to go to work the next day, the chain had been cut and the gauge and the gauge transport box were missing. The gauge is a Troxler 3430, Serial Number 34160, containing approximately 8 millicuries of Cesium-137 and 40 millicuries of Americium-241:Beryllium. A police report has been filed. The Department has requested additional information and continues to investigate the event."

Arizona Incident No.: 21-004

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.

EN Revision Text: UNANALYZED CONDITION
"At 0930 EDT on 5/3/2021, it was determined that during entries into the Fermi 2 Reactor Building Steam Tunnel (RBST) on 4/17/2021, 4/18/2021, and 4/21/2021 that the door was not controlled according to site procedures. The RBST door is credited as a hazard barrier for various high-energy line break (HELB) scenarios. On the identified dates, the RBST door was left open for brief periods during maintenance related activities in the RBST. This condition is not bounded by existing analyses as the door is assumed to be closed throughout a HELB event. The time period that the door was open was less than one hour in each case, as stay times in the room are inherently limited by industrial and radiological conditions. Individuals remained in the area to close the door if needed, but existing analyses do not address the ability to perform those actions under all HELB scenarios.

"There is no impact to the health and safety of the public or plant personnel as the door is currently closed and latched and access into the area has been restricted to normal ingress and egress per site procedures, which ensures consistency with existing analyses. Therefore, this event is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(ii)(B). Investigation into the cause is ongoing. Preliminary review of the extent of this condition identified entries into the RBST on other occasions during the past three years where the conditions may also have not been bounded by existing analyses. The additional occasions where the door may have been held open were on 9/22/2018 (MODE 3), 10/26/2018 (MODE 1 ), 11/2/2018 (MODE 1), and 3/21/2020 (MODE 3). Each of these instances was also less than one hour with the exception of the occurrence beginning on 10/26/2018 which lasted approximately 10 hours to support packing leak repairs on a HPCI [High Pressure Coolant Injection] Outboard Isolation Valve."

The licensee notified the NRC Resident Inspector.

EN Revision Text: AGREEMENT STATE REPORT - RADIOGRAPHY CAMERA SOURCE UNABLE TO RETRACT

The following was received via e-mail from the Rhode Island Dept. of Health, Radiation Control Agency:

"A licensee, Electric Boat Corporation, reported the inability to retract a 1.62 TBq (43.8 Ci) Co-60 source (QSA Global, Inc. Model A424-14, S/N 81346G) into the radiography exposure device (QSA Global, Inc. Model Sentry 330, S/N P30106) on March 7, 2021, at Electric Boat's Quonset Point Facility. At approximately 0120 [EDT], the [source] was [extended] without any issue.

"At the completion of the exposure, the radiographer attempted to retract the source into the exposure device, and attempted to re-expose the source to verify that the auto-locking mechanism on the Sentry 330 exposure device had engaged. At this time, the radiographer noted that the auto-lock did not engage and that dose rates indicated by his ND-2000A survey instrument at the reel (remote control) remained at approximately 10 mrem/hr. The radiographer then attempted to expose and retract the source to engage the locking mechanism 2 additional times without success.

"At approximately 0156 [EDT], the RSO [(Radiation Safety Officer)] was notified of the inability to retract a Cobalt-60 source into its exposure device. The RSO was able to observe the set up with an inspection mirror from the opposite side of the large part being inspected and determined that the guide tube had become disconnected from the collimator, exposing 10-12 feet of drive cable on the deck, and the source pigtail had become stuck in the collimator.

"After creating and briefing retrieval and contingency plans, source retrieval evolution began at 0640 [EDT]. The RSO Delegate secured the source pigtail in the collimator with a 6 ft long remote handling tool to prevent the source from leaving the collimator prematurely while the RSO stepped out from behind the lead shield with another 6 ft long remote handling tool to move the guide tube from the deck back up to the collimator. While the RSO was straightening out the guide tube and drive cable, a radiography supervisor was slowly retracting the drive cable at the reel to remove the 10-12 ft of drive cable slack on the deck while the RSO communicated via radio. Once the drive cable slack was removed and the RSO guided the guide tube back up to the collimator and tension on the source pigtail was released, the RSO Delegate released control of the source and it was immediately retracted by the radiography supervisor into the exposure device. The source was confirmed to be secured in its device by survey, and the evolution was declared secure at 0649 [EDT].

"RI Radiation Control Agency has investigated the report by Electric Boat Corporation and has determined that this does not have generic implications for the security of sources in radiography equipment at Electric Boat Corporation. The incident is considered closed by RI Radiation Control Agency."
