AGREEMENT STATE REPORT - NUCLEAR DENSITY GAUGE STOLEN FROM JOB SITE
The following report was received from the Arizona Department of Health Services via email:
"The Department [Arizona Department of Health Services] received notification on October 8, 2019, that a Humboldt 5001 series, SN#5820, portable gauge was stolen from a work site in San Luis, Arizona, on September 5, 2019. The portable gauge contains 44 milliCuries of americium-241 and 11 milliCuries of cesium-137. The Arizona Department of Public Safety and the San Luis Police Department were notified of the event by the licensee on September 5th and a police report was filed. The Department [Arizona Department of Health Services] has requested additional information and continues to investigate the event."
Arizona Incident Number: 19-023
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 - SHUTTER CONTROL MECHANISM MALFUNCTION
The following was received from Kentucky Department of Health Radiation Branch (KY RHB) via email:
"KY RHB was notified on 9/6/2019 by a representative from a specifically licensed facility, Big Rivers Electric Corp., that at 1400 EDT on Thursday 09/05/2019, one fixed gauging device (Kay Ray Dual Model 7080, Serial Number 13321G), containing a 100 mCi Cs-137 source (serial No. 12376-V; assay date 6/1/1981) had developed a potential problem. An investigation showed that the shutter remained partially shut when the arm of the on-off shutter mechanism was moved to the fully open position. The gauge is located 25 feet above the floor between fly ash hoppers, and was left on the hopper with the shutter in the closed position. Pending removal of the source no access has been permitted to the two affected hoppers, and all maintenance activities will be delayed until the device has ben removed. No overexposures to the public or to plant workers have been reported. The licensee will be contacting a licensed service provider to remediate this situation."

CONTAINMENT PENETRATION DISCOVERED NOT ISOLATED
"At 2115 CDT on 9/5/2019, an inside containment test connection and inoperable outside containment isolation valve were discovered to be open for a containment air sample penetration. This resulted in the containment penetration not being isolated. The inside containment test connection was closed at 2322 CDT on 9/5/2019.
"This event is being reported under 10 CFR 50.72(b)(3)(v)(C) and (D) and 10 CFR 50.72(b)(3)(ii)(B).
"There was no impact to the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."
* * * UPDATE FROM PAUL BURTON TO HOWIE CROUCH AT 1342 EST ON 11/7/19 * * *
"This event was originally reported on September 6, 2019 under 10 CFR 50.72(b)(3)(v)(C) and (D) and 10 CFR 50.72(b)(3)(ii)(B). Upon completion of the investigation of the event, it was determined that the event had insignificant safety consequences because the containment breach was disconnected from the Reactor Coolant System by a series of closed valves for the duration of the event. Additionally, the lines to the inside containment connection and the outside inoperable containment isolation valve that was found to be open as well as the main line connecting and passing through the penetration were one-inch diameter lines. Analysis determined that containment breaches that are less than a three-inch diameter do not lead to a large radiation release.
"The event did not place the plant in an unanalyzed condition that significantly degrades plant safety. Therefore, 10 CFR 50.72(b)(3)(ii)(B) did not apply to this event and this notification is to retract reporting under that criterion."
The licensee notified the NRC Resident Inspector. Notified R4DO (Drake).
