SURFACE CONTAMINATION ON OUTSIDE OF PACKAGE
The following is a synopsis of information provided by the licensee via phone and email:
On 10/17/23 around 1100 CDT, the licensee received two packages each containing technetium-99m. Swipe readings on the packages revealed gross counts of 19158 disintegrations per minute (DPM) for the first package and 6874 DPM for the second package. The licensee's radiation safety officer (RSO) and the supplier, Cardinal Health, were notified. The inside of the package was also wipe tested and was not contaminated. The nuclear medicine department was surveyed, including the hot lab and department hallway and no additional contamination was found. The licensee has placed the two cases in short term storage and intends to send them back to Cardinal Health when they are at background. The licensee also called and left a message with NRC Region 3 personnel.

AUTOMATIC REACTOR TRIP
The following information was provided by the licensee via email:
"At 2159 on 10/24/2023, with Unit 3 in Mode 1 at 100 percent power, the reactor was automatically tripped due to an actuation signal into the Unit 3 reactor protection system protection rack during maintenance. The trip was uncomplicated with all systems responding normally post trip. Decay heat is being removed via auxiliary feed water system and the steam dump system. Unit 4 is not affected.
"This event is being reported pursuant to 10CFR50.72(b)(2)(iv)(B) and 10CFR50.72(b)(3)(iv)(A). The NRC Resident Inspector has been notified.
"The cause of the automatic reactor trip will be investigated by the licensee."
