IODINE-125 SEED INADVERTENTLY LEFT IN PATIENT
The following is a summary of a call with the licensee:
On October 28, 2020, during a routine mammogram, the radiologist found an I-125 seed in the left axilla that was believed to have been previously removed. The 250 microCi seed was implanted on July 5, 2019 as part of a 10 CFR 35.1000 lesion location procedure. It was supposed to have been removed the same day during removal of the lesion.
On the follow-up x-ray of the lesion, the seed was not identified. The radiologist called the operating room, which stated and documented that they had recovered the seed. The licensee noted that there was a second seed implanted in the left breast that was recovered. Both seeds are documented on the same paperwork.
An investigation is in progress, but the licensee believes that the dose to the patient is more than 50 rem to the tissue and total dose delivered differs from the prescribed dose by 20 percent or more.
The patient was informed and no effects are expected.
The licensee will notify the NRC Region 3 Office.
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.

"At 2150 CST on 11/04/2020, it was discovered that Unit 1 High Pressure Coolant Injection System (HPCI) was INOPERABLE; therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v), as an event or condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to mitigate the consequences of an accident.
"During performance of 1-SR-3.5.1.7, HPCI Main and Booster Pump Set Developed Head and Flow Rate Test at Rated Reactor Pressure, Unit 1 HPCI was manually tripped by the control room operator due to local report of excessive shaking of the cooling water supply from the booster pump line.
"There was no impact to the safety of the public or plant personnel. The NRC Resident Inspector has been notified.
"CR 1650042 documents this condition in the Corrective Action Program."

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."

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.
