EN Revision Text: PRESSURE BOUNDARY DEGRADED / BOTH TRAINS OF HIGH PRESSURE SAFETY INJECTION INOPERABLE
"At 1257 EST on January 3, 2024, it was determined that a class 1 system barrier had a through wall flaw with leakage. The leakage renders both trains of high pressure safety injection inoperable. The unit is being cooled down to cold shutdown to comply with technical specifications.
"This event is being reported pursuant to 10 CFR 50.72(b)(3)(ii)(A) and 10 CFR 50.72(b)(3)(v)(D).
"The NRC Resident Inspector has been notified."
The following additional information was obtained from the licensee in accordance with Headquarters Operations Officer Report Guidance:
At the time of the discovery, the unit was shutdown in mode 3. The unit was experiencing signs of reactor coolant system leakage and a shutdown was initiated in order to search for possible sources. The unit is currently cooling down and proceeding to mode 5, where the safety function is not required.
* * *UPDATE AT 1257 EST ON 02/12/24 FROM B. MURRELL TO T. HERRITY***
"The purpose of this notification update is to retract a portion of a previous report, made on 1/03/2024 at 1257 EST (EN 56912). Notification of the event to the NRC was initially made as a result of declaring both trains of unit 2 high pressure safety injection system inoperable due to reactor coolant barrier through wall leak on the vent line for the 2A2 safety injection tank.
"Subsequent to the initial report, Florida Power and Light has concluded that the through wall leak rate was insignificant, and therefore the safety injection system's safety-related function was maintained.
"Therefore, this portion of the event is not considered a safety system functional failure and is not reportable to the NRC pursuant 10 CFR 50.72(3)(v)(D).
"This update does not affect the original 10 CFR 50.72(b)(3)(ii)(A) report for the degraded condition related to the reactor coolant barrier through wall leak.
"The NRC Resident Inspector has been notified."

AGREEMENT STATE REPORT - FAILED SOURCE LEAK TEST
The following is a summary of information received from the Georgia Radioactive Material Program (the Department) via email:
On January 6, 2024, the Department was notified by the licensee, that on January 3, 2024, a nuclear medicine technologist was performing routine leak testing of sealed sources in preparation of returning the sources to the manufacturer. The leak test indicated one of the sealed sources (Co-57, 21.12 microcuries as of 2/1/2023, manufacturer: Eckert and Ziegler, model: PHI-0124, serial number: V6-599) had more than 0.005 microcuries of removable Co-57 contamination. The sealed source was secured, the radiation safety officer (RSO) was notified, and decontamination protocol was followed.
Post-decontamination surveys and wipe tests of the staff and department indicated that there was no detectable contamination in the department or on staff members. The sealed source and the waste generated during the decontamination process were placed in leakproof containers and marked as containing Co-57. All items are currently stored in the nuclear medicine hot lab. Disposal with a waste disposal company has been arranged.
Georgia NMED event number: 76
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.
