AGREEMENT STATE REPORT - STUCK SHUTTERS
The following is a synopsis of information received from Maine Radiation Control Program via telephone:
The licensee was in the process of shutting down the plant when it was discovered that 4 level gauges on one tank have stuck open shutters. The model and activity are not available at this time. Due to the location of the gauges, no exposures were recorded nor are any expected. This investigation for the stuck open shutters is on going.

MEDICAL EVENT - PATIENT UNDERDOSE
The following is a summary of information provided by the licensee via phone:
A patient underwent an eye plaque procedure where they were to receive 85 Gy of Iodine-125 over a seven day period. The patient received an estimated dose of 57 Gy. The total dose delivered differs from the prescribed dose by greater than 20 percent. The licensee believed the seed could have shifted during the 7 days. A written report will be forwarded when complete.
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.

AGREEMENT STATE REPORT - CONTAMINATION EVENT
The following information was received via email from the New Jersey Department (NJDEP) Bureau of Environmental Radiation:
"On 6/28/2023, NJDEP Bureau of Environmental Radiation (BER) was notified by its NRC Regional State Agreements Officer of an allegation made by a concerned citizen regarding a powder being sold by an online marketplace. The company address is in New Jersey. The citizen believed the powder contained Thorium-232 (Th-232). BER subsequently followed up with a site investigation and confirmed that Th-232 was present. The individual on-site stated that the powder had been mixed into paint, which was used to paint the walls in his basement and bathroom. The investigation is ongoing.
"On 7/8/2023, BER staff visited the seller's residence to perform an interview and contamination survey. The survey confirmed the presence of alpha and beta contamination in the residence. A sample of the powder was also collected and sent for gamma spectrometry analysis by a certified laboratory. Results of the analysis were received on 8/14/2023, and indicated concentrations of Th-232 as 14,800 pCi/g. On 8/15/2023, an estimate on the total activity present was made, and it was determined that this was a reportable event."

MANUAL REACTOR TRIP AND AUTOMATIC ACTUATION OF AUXILIARY FEEDWATER SYSTEM
The following information was provided by the licensee via email:
"At 1724 EDT, on August 22, 2023, with Unit 1 in Mode 1 at 100 percent power, the reactor was manually tripped due to a failure of the non-safety heater drain pump 'B' and the failure of the non-safety condensate pump 'A' to automatically or manually start. At 1735 EDT, a fire was identified on heater drain pump 'B' and was extinguished by the onsite fire brigade at 1807 EDT. Operations responded and stabilized the plant. The trip was not complex, with all safety systems responding normally post-trip. Decay heat is being removed by the main steam system to the main condenser using the steam dumps. There was no impact to Units 2, 3, or 4.
"An automatic actuation of the auxiliary feedwater system (AFW) also occurred, as expected, due to lo-lo steam generator levels resulting from the reactor trip. AFW is currently controlling all steam generator levels at their normal levels. Due to the reactor protection system actuation while critical, this event is being reported as a four-hour, non-emergency notification per 10 CFR 50.72(b)(2)(iv)(B). Due to the notification of another government agency, the Burke County Fire Department, this event is being reported as a four-hour, non-emergency notification under 10 CFR 50.72(b)(2)(xi). The Burke County Fire Department was not needed to extinguish the fire. This event is also being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(iv)(A) as an event that resulted in a valid actuation of the auxiliary feedwater system.
"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."
