LOST LUTETIUM-177 SOURCE

The following synopsis was provided by the licensee via phone:

On 5/21/24, a 200 millicurie lutetium-177 (Lu-177) source was delivered to the Karmonas Cancer Institute and was placed in a clean hot laboratory. A physics resident cleaning the hot laboratory placed the box containing the source outside the hot lab on a trash can. A custodian threw the box in the trash at the end of the day. The licensee notified the trash management company and the facility security department. No threat to public health is expected based on source packaging.

The NRC Region 3 inspector was also notified.


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.

AUTOMATIC REACTOR TRIP

The following information was provided by the licensee via email and phone:

"On May 29, 2024, at 0624 EDT, Unit 1 automatically tripped from 100 percent power due to a negative rate trip. The unit has been stabilized in mode 3 at normal operating temperature and pressure. The reactor trip was uncomplicated and all control rods fully inserted into the core. This reactor protection system actuation is reportable per 10 CFR 50.72(b)(2)(iv)(B). The auxiliary feedwater pumps actuated as designed because of the reactor trip and is reportable per 10 CFR 50.72(b)(3)(iv)(A) for a valid engineered safety feature (ESF) actuation. Decay heat is being removed by the condenser steam dump system and Unit 1 is in a normal shutdown electrical lineup. Unit 2 was not affected by this event."

The NRC Resident has been notified.
