ACTUATIONS OF REACTOR PROTECTION SYSTEM
The following information was provided by the licensee via email:
"On 05/06/2023, at 1552 [EDT] with Seabrook Unit 1 in Mode 3 at zero percent power, while performing digital rod position indication system surveillance testing, shutdown bank 'E' stopped withdrawing. In response, the reactor trip breakers were manually opened, initiating a valid actuation of the reactor protection system (RPS).
"Subsequently, at 2253 while continuing to perform digital rod position indication system surveillance testing, shutdown bank 'C 'stopped inserting. Reactor trip breakers were manually opened, initiating a valid actuation of the RPS.
"The RPS responded as designed during both events, and both actuations are being reported pursuant to 10 CFR 50.72(b)(3)(iv)(A).
"The NRC Resident Inspector has been notified."

AGREEMENT STATE REPORT - LIQUID RADIOACTIVE CONTAMINATION
The following information was provided by Utah Department of Environmental Quality, Division of Waste Management and Radiation Control [the Division], via email:
"The Division was notified of the incident at 7:38 AM on May 8, 2023, by email from the Utah Department of Environmental Quality's duty officer who was on call on Saturday May 6, 2023.
"Information received from the on-call duty officer: The Radiation Safety Officer reported a radioactive material (rubidium-82) release of an unknown amount due to a leaking generator. She said that Cardiac Molecular Imaging found liquid in the bottom of a well chamber of the infusion system. Proper decontamination procedures were followed, the liquid was placed in radioactive waste storage, a wipe test was done, and everything was cleaned up. She said this has happened before. There was no impact to patient treatment. The generator will be shipped back to the manufacturer for investigation. The incident has been contained and there is no immediate threat.
"This appears to be the exact same issue that we notified the NRC for the UT23-0002 and UT23-0003 incidents.
"The Division will investigate this matter and update the record upon completion of the investigation."
