AUTOMATIC ACTUATION OF AUXILIARY FEEDWATER SYSTEM (AFW)
The following information was provided by the licensee via email:
"At 0852 [EDT] on May 19, 2023, with Unit 2 in Mode 3 at zero percent power, an actuation of the auxiliary feedwater system (AFW) occurred. The reason for the AFW auto-start was a failed start attempt of the 'B' main feedwater pump. The 'A' and 'B' motor driven auxiliary feedwater (MDAFW) pumps automatically started as designed when the 'Loss of Both Main Feedwater Pumps' signal was received.
"This event is being reported in accordance with 10 CFR 50.72(b)(3)(iv)(A) as an event that results in a valid actuation of the AFW system.
"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

AGREEMENT STATE REPORT - PACKAGE EXCEEDED RADIATION LIMITS
The following information was received from the Massachusetts Radiation Control Program (the Agency) via email:
"A telephone call received by the Agency from the [Radiation Safety Officer] RSO of Invicro, LLC, at 1054 EDT on 5/19/2023. A package was received on 5/19/2023 at approximately 1000 EDT at the licensee's site that exceeded the dose rate limit of 200 mrem/hr on the external surface of the package. The radionuclide was fluorine-18 (F-18) in liquid form enclosed in a glass vial. The assayed dose was 499 mCi at 0930 at PETNET Solutions, Inc. in Woburn, MA, the distributor of the F-18.
"The package was labeled Yellow II and the maximum surface dose rate should therefore not exceed 50 mrem/hour for a Yellow II labeled package. The package upon shipment was measured by the shipper to have a surface dose rate of 7 mrem/hour and a transport index (TI) of 0.4.
"The licensee reported that 5 wipe samples were taken on the external surface of the package with no resultant removable contamination observed. It was reported that the glass vial contained approximately 350 mCi of F-18 at the time the package was opened. The external dose rates on all external surfaces continued to exceed 200 mR/hr, even with the vial removed from the package.
"Surveys of areas where the package was opened, and where the vial was transported, are undergoing. The vial is currently stored in a hot cell. The external package is being stored in a shielded location. Personnel are being surveyed for contamination. At this time there is no indication of external contamination of the shipping package.
"The Agency, Invicro LLC, and PETNET Solutions, Inc. are in communication working the details of the scenario and potential personnel exposer.
"The Massachusetts Radiation Control Program considers this to be an open reportable event."

AGREEMENT STATE REPORT - LOST AND RECOVERED SOURCE
The following report was received via email by the Colorado Department of Health:
"On May 19, 2023, the RSO [Radiation Safety Officer] at Memorial Hospital, University of Colorado Health, reported a missing 1.2 mCi germanium-68 sealed source. The source was determined to be an internal quality control source of a PET/CT [Positron Emission Tomography/Computed Tomography] camera. The source was identified as missing during a routine 6-month inventory performed on April 21, 2023.
"The PET/CT camera was purchased by Siemens Medical Solutions USA, Inc. in December 2022. Siemens subcontracted the decommissioning of the camera to a 3rd party (Clinical Imaging Systems), however, they failed to remove the source prior to transporting/shipping the camera to a Clinical Imaging System's warehouse. The source has been removed from the camera and is currently secured in a locked room at the warehouse. Memorial Hospital has been working with Siemens to have a licensed service provider ship the source back to Memorial Hospital or directly to a licensed recipient for disposal."
Colorado Event Number: CO230013
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.
