UNPLANNED CONTAMINATION
The following information was provided by the licensee via telephone:
On March 26, 2024, at 0800 EDT, a spill occurred outside of the Cardinal Health facility's hot-cell. The spill was an aqueous thorium suspension containing 0.5 microcuries, Th-229 and 1.0 microcuries, Th-228. The spill was confined to the licensee's facility.
On March 29, 2024, the licensee became aware of a potential airborne radioactivity hazard posed by the spill and directed personnel to wear respiratory protection in the area of the spill. Personnel dosimetry reports indicate that all external radiation exposures were below regulatory limits. Bioassay samples were taken and preliminary bioassay results were below the analytical minimum detectable concentration. Final bioassay results are pending more sensitive analysis.
Decontamination activities were completed on April 12, 2024.

EN Revision Text: ACTUATION OF REACTOR PROTECTION SYSTEM
The following information was provided by the licensee via phone and email:
"On March 26, 2024 at 1115 CDT, Grand Gulf Nuclear Station experienced an actuation of the reactor protection system (RPS) due to high reactor coolant system pressure. The plant was in Mode 4 at zero percent power and performing scram time testing. All rods were fully inserted at the time of the RPS actuation, and all required equipment responded as designed.
"This actuation is being reported in accordance with 10 CFR 50.72(b)(3)(iv)(A).
"The cause of the event is under investigation.
"The NRC resident inspector has been notified."

AGREEMENT STATE REPORT - DETACHED SOURCE
The following was received from the Texas Department of State Health Services (the Department) via phone and email:
"On March 26, 2024, the Department was notified by the licensee's radiation safety office (RSO) that earlier this day a radiography crew had a source disconnect while using a SPEC 150 exposure device. The device contained a 23 curie, iridium-192 source.
"The disconnect occurred on the first shot of the day. The RSO reported that the radiographers had completed set up for the first shot but had failed to properly connect the guide tube to the camera. When the radiographers cranked the source out and it hit the collimator, the guide tube popped loose from the camera. The radiographer immediately attempted to crank the source back into the camera but when the source reached the end of the guide tube the source pigtail disconnected from the drive cable.
"The radiographers set up new boundaries and contacted the RSO. An RSO from a nearby office responded to the location. The RSO was wearing a self-reading dosimeter (SRD), alarming rate meter, and TLD [thermoluminescent dosimeter] exposure badge. The RSO placed the camera on the source for shielding, attached the source back to the drive cable, and retracted the source into the camera. The responding RSO's SRD was reading off scale after retracting the source. The badge has been sent to the licensee's dosimetry processor for emergency processing.
"The licensee does not believe any individual exceeded any limit due to this event. Additional information will be provided as it is received in accordance with SA-300."
