Event Notification Report for March 29, 2023

EN Revision Imported Date: 3/29/2023

EN Revision Text: REACTOR COOLANT SYSTEM (RCS) BOUNDARY DEGRADED CONDITION

The following information was provided by the licensee via email:

"At 2257 [CDT] on 3/14/2023 during the 2R22 refueling outage on Browns Ferry Nuclear Plant Unit 2, it was determined there was RCS boundary leakage from five of eight sensing lines that pass through containment penetrations X-30 and X-34 that did not meet the requirements of Section XI, of the ASME Boiler and Pressure Vessel Code. The condition will be resolved prior to plant startup. 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."

* * * RETRACTION ON 03/28/2023 AT 1059 EST FROM CASEY CARTWRIGHT TO THOMAS HERRITY * * *
The following information was provided by the licensee via email:

"The purpose of this notification is to retract a previous Event Notification, EN 56411 reported on 3/14/23.

"Following the initial notification, further analysis of the condition was performed. It was determined that the leaking pipe weld was ASME Section XI Code Class 2 piping which falls under the requirements of ASME Section XI Subsection IWC and not Subsection IWB. Therefore, this condition does not represent a serious degradation of the nuclear power plant., including its principle safety barriers. Based upon the above, the leaks identified on the ASME Section XI Code Class 2 equivalent Main Steam sense lines are not reportable under 10 CFR 50.72(b)(3)(ii).

"Therefore, the NRC non-emergency 10 CFR 50.72(b)(3)(ii) report was not required and the NRC report 56411 can be retracted and no Licensee Event Report under 10 CFR 50.73(a)(2)(ii) is required to be submitted."

AGREEMENT STATE REPORT - MEDICAL EVENT

The following information was received via email:

"On March 21, 2023, a report of misadministration was received by the Arkansas Department of Health from Baptist Health Medical Center, Little Rock at 0945 CDT.

"A 72 year old female came to the Baptist Health Little Rock Nuclear Medicine department for a radioactive iodine thyroid scan. The patient had been scheduled in our [Electronic Medical Record system] as a Total Body Iodine [TBI] Scan with Thyrogen. The patient was given the first dose of Thyrogen on Monday, March 13th. She came in the following day for her second dose of Thyrogen. At this time, the nuclear medicine technologist was informed that the patient still had her thyroid. The technologist called the radiologist and asked how long the patient needed to be off of Thyrogen to have an I-123 scan. The technologist was told to call the radiopharmacy and ask. The technologist was also told to call the ordering provider to clarify the order. The technologist communicated with the ordering provider's nurse. The ordering provider did not know what to do at this point other than to continue with the study. No explanation was given to the ordering provider about the TBI scan or the effects of I-131 on their patient. The technologist proceeded with dosing the patient on March 15th with 4.4 mCi of I-131. The patient came back on Friday, March 17th for imaging. At this point, the radiologist realized that the technologist had performed the incorrect study and misadministered I-131. The health physicist was notified, and on Monday, March 20th, estimated that since no uptake was performed, that the patient received, at minimum, 14,000 rads/500 Rem to her thyroid gland from the dose of I-131."

Arkansas Event Report ID No.: AR-2023-002

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 EXIT SIGNS

The following is a synopsis of information provided by the Colorado Department of Public Health and Environment via email:

The licensee discovered twelve tritium exit signs were lost. The exit signs are SRB Technologies Model BXU10GS containing 9.21 Ci of tritium (H-3) each. This is being reported under Colorado Regulations Section 4.51.1.1 (10 CFR 20.2202(a)(1)(i)).

Event Report ID No.: CO230008

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 - BROKEN NUCLER GAUGE SHUTTER

The following information was received from the Pennsylvania Department of Environmental Protection via email:

"On March 21, 2023, the licensee discovered a broken shutter on one of its devices, a Berthold, LB8010, Serial number 10094, with 20 mCi of cesium 137. The licensee reported the shutter is in the closed position and cannot be moved. The device has been removed from service and secured at the licensee's storage facility in Mill Hall, PA. The manufacturer has been contacted. The gauge will be returned for repair or replacement. No personnel overexposure has occurred."

PA Event Report Id NO: PA230012

AGREEMENT STATE REPORT - LEAKING SEALED SOURCE

The following information was received from the Georgia Radioactive Materials Program via email:

"Radionuclide: Cs-137 Vial; Serial Number: 1360-12-8; Current Activity: 0.035 mCi

"During a routine sealed source inventory check on March 17, 2023, a physicist identified a damaged spot on the referenced Cs-137 vial. The source was wiped and then immediately placed back into its shielded container. The outer area of the container was sealed with tape, and all potentially contaminated items (e.g., gloves, tape, wipes, etc.) were triple bagged, sealed, labeled, and placed in a storage cabinet in the hot lab. Area surveys and wipe tests performed in the location where the source was located showed no signs of contamination. As such, the leaking source has been fully contained and is currently secure in the hot lab. The leak test samples were acquired and analyzed on March 17, 2023.

"We [the licensee] are currently in the process of obtaining quotes from various hazardous waste disposal companies in our region. Once the source has been properly disposed of, we [the licensee] will notify your department [Georgia Radioactive Materials Program] and provide relevant documentation."

Georgia Incident Report No.: 63

FITNESS FOR DUTY REPORT
