AGREEMENT STATE REPORT - SHUTTER STUCK CLOSED ON NUCLEAR GAUGE
The following is a synopsis of a notification from the Oklahoma Department of Environmental Quality (OK DEQ) via telephone:
OK DEQ was notified on 10/30/2020 by Western Farmers Electric Cooperative that they had discovered a fixed gauge (Texas Nuclear 57157C), with a stuck closed shutter. Licensee plans to secure the shutter in the closed position and decommission the device.
* * * UPDATE ON 10/30/2020 AT 1716 EDT FROM KEVIN SAMPSON TO THOMAS KENDZIA * * *
The following update was received from OK DEQ via email:
"This incident was originally reported to OK DEQ in September. The gauge in question is mounted approximately 15 feet above grade and the shutter is operated by cables. In September the licensee informed [OK DEQ] that the cable system was not working but the shutter was functional. At the time, [OK DEQ] concluded that this was not reportable. On October 1, a technician was on site to repair the cable system but discovered that the shutter was now stuck in the closed position. The licensee did not report this to [OK DEQ] until today."

AGREEMENT STATE REPORT - DOSE DELIVERED DIFFERS BY GREATER THAN 20 PERCENT
The following was received from Georgia Radioactive Materials Program (GA RMP) via email:
"On Oct 30, 2020, [GA RMP] received an email, from the Assistant RSO [Radiation Safety Officer, Emory University], informing [GA RMP] that a second Y-90 TheraSpheres event occurred on Oct 29, 2020.
"A patient was administered with 16.2 mCi of Y-90 TheraSpheres using a high flow microcatheter and a larger syringe. The product representative from Boston Scientific was there to consult with the authorized users and technologist prior to treatment. Once it appeared that the micro catheter and Y-90 line and vial were in proper positioning, the Y-90 was administered. Subsequently, the line was flushed three times using approximately 50-60 ml of saline.
"After the procedure, all items were surveyed and calculated that only 7.3 mCi of Y-90 was administered. Since all waste was surveyed as a whole and not independently from each item, the Assistant RSO did not have the information to discern whether residual Y-90 remained in each product (micro-catheter, line, and vial).
"Until they can determine the causes of the misadministration, Emory has halted TheraSpheres administration at Emory at Midtown, and substituted Y-90 Sirspheres where they can. Emory University Hospital also uses TheraSpheres, but has not reported any problems. Emory investigation is ongoing. [GA RMP] will provide follow-up information as it is obtained."
Georgia Incident No: 32
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.

AGREEMENT STATE REPORT - LOST DENSITY GAUGE
The following was received from the Arizona Department of Health Services (Department) via email:
"The Department received notification from the licensee that a portable gauge was lost. A technician left the portable gauge on the tailgate of his truck while completing paperwork and then drove off. When he realized that the gauge was missing, he retraced his steps but was unable to locate it. The gauge is a Troxler 3430, Serial Number 32909, containing approximately 8 milliCuries of Cesium-137 and 40 milliCuries of Americium-241:Beryllium. The Department has requested additional information and continues to investigate the event."
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: AGREEMENT STATE REPORT - LOST OR MISSING RADIOGRAPHY CAMERA
The following is a summary of the information received from the State via email:
On 11/3/20, the licensee reported to the Oklahoma Department of Environmental Quality that a radiography camera was missing. The device was shipped from a Stanley facility in Pennsylvania to Oklahoma. The shipping paper arrived at the Oklahoma facility on 11/2/20, but the package containing the camera was missing. On 11/2/20, Stanley notified the shipment carrier of the missing package.
The radiography camera is a QSA Global Model 880 Delta (S/N: D14241) with a 25.5 Ci Ir-192 source.
* * * UPDATE ON 11/5/20 AT 1608 EST FROM KEVIN SAMPSON TO ANDREW WAUGH * * *
The device has been located by the shipment carrier and is scheduled to be returned to the licensee.
Notified R4DO (Proulx), NMSS (Rivera-Capella), IR MOC (Grant), ILTAB (Clark), and NMSS Events Notification (email).
THIS MATERIAL EVENT CONTAINS A "CATEGORY 2" LEVEL OF RADIOACTIVE MATERIAL
Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.

INADVERTENT/MALFUNCTIONING SIREN ACTIVATION
"On November 10, 2020, at 1827 CST, River Bend Station (RBS) received a report of a single inadvertent and malfunctioning siren which is part of the Emergency Notification System. The siren was heard by residences in the area and they contacted local agencies, who in turn contacted RBS.
"This siren activation was not related to any condition or event and no emergency has occurred at RBS. RBS has notified the appropriate authorities and the Governor's Office of Homeland Security and Emergency Preparedness of the inadvertent siren activation. RBS has sent a team to locally disable the siren to prevent any further inadvertent sounding and it is now disabled. A press release from Entergy is not planned at this time.
"The NRC resident has been notified of the event."
The licensee also notified the East and West Feliciana Parish Authorities. If an emergency notification were required, there is overlap of working sirens to cover the area of the siren that is out of service.
"On November 10, 2020, at 1827 CST, River Bend Station (RBS) received a report of a single inadvertent and malfunctioning siren which is part of the Emergency Notification System. The siren was heard by residences in the area and they contacted local agencies, who in turn contacted RBS.
"This siren activation was not related to any condition or event and no emergency has occurred at RBS. RBS has notified the appropriate authorities and the Governor's Office of Homeland Security and Emergency Preparedness of the inadvertent siren activation. RBS has sent a team to locally disable the siren to prevent any further inadvertent sounding and it is now disabled. A press release from Entergy is not planned at this time.

NOTIFICATION OF STEAM GENERATOR TUBE DEGRADATION
"At 1311 EST on November 11, 2020, it was determined, after evaluation of the Watts Bar Nuclear Plant (WBN) Unit 2 Steam Generator (SG) tube eddy current test data collected during the on-going refueling outage, that the WBN Unit 2 Reactor Coolant System pressure boundary did not meet the performance criteria for SG tube structural integrity. Specifically, SG number 3 failed the condition monitoring assessment for conditional burst probability. WBN has completed tube plugging and additional corrective actions are in progress. This event is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(ii)(A).
"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."
