EN Revision Text: SHUTDOWN REQUIRED BY TECHNICAL SPECIFICATIONS DUE TO INOPERABLE CORE SPRAY
The following information was provided by the licensee via fax:
"At time 0207 CDT, Cooper Nuclear Station (CNS) entered Technical Specification [Limiting Condition for Operation] LCO 3.0.3 due to declaring core spray subsystems A and B inoperable. This declaration was based on an issue with relays installed from the same manufacturing batch. The ability of the relays to function correctly to annunciate loss of logic power was called into question and they were declared inoperable. The plant has initiated actions to repair/replace affected relays.
"This event is reportable under 10 CFR 50.72(b)(2)(i) as an initiation of any nuclear plant shutdown required by Technical Specifications. In addition, this event Is reportable under 10 CFR 50.72(b)(3)(v) as a condition that could have prevented the fulfillment of a safety function for the core spray systems.
"NRC Resident Inspector was notified."
* * * UPDATE ON 5/8/2023 AT 1335 EDT FROM ANDREW ASKINS TO BRIAN LIN * * *
The following information was provided by the licensee via email:
"Technical Specification LCO 3.0.3 was exited at 0805 CDT on May 8, 2023. A reasonable expectation of operability was developed for the core spray subsystems A and B. There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified. Shutdown was initiated and power was reduced approximately 45 percent. Reactor power is currently at 55 percent at the time of notification."
Notified R4DO (Werner) via email.
* * * UPDATE ON 5/9/2023 AT 1441 EDT FROM ANDREW ASKINS TO DONALD NORWOOD * * *
The following information was provided by the licensee via email:
"CNS is retracting the 8-hour 10 CFR 50.72(b)(3)(v) non-emergency notification, for a condition that could have prevented the fulfillment of a safety function, made on May 8, 2023, at 0207 CDT (EN# 56509). Subsequent evaluation concluded that the core spray subsystems remained operable in accordance with the Technical Specifications Requirements 3.5.1, ECCS - Operating. As a result of the core spray system remaining operable, no loss of safety function occurred. The NRC Senior Resident Inspector has been notified."

AGREEMENT STATE REPORT - FAILED SHUTTER
The following information was provided by the North Dakota Department of Health, Radiation Control Program via email:
"On 5/8/2023, Minn-Dak Farmers Cooperative in Wahpeton, ND, had an equipment failure on a fixed nuclear gauge (Thermo MeasureTech Model No. 7062) with a 46.7 millicurie Cs-137 sealed source (General Radioisotope Products, Inc. Model No. 850233). The licensee was performing the required routine shutter checks and it was found that shutter on the gauge listed above failed to fully close. There was no visual damage to the shutter, gauge or source at the time of the shutter check. Licensee is in contact with the service provider Vega to replace the gauge."

POTENTIAL MEDICAL EVENT
The following information was provided by the licensee via phone and email:
"In accordance with 10 CFR 35.3045, [Henry Ford Hospital is] reporting a potential medical event.
"On May 8, 2023, a patient was treated with Y-90 TheraSpheres. The total activity prescribed in the written directive was 11.5 mCi to the left lobe of the liver and 11.37 mCi was delivered (99.2 percent). The therapeutic dose was prescribed to be delivered to segment 4 of the left lobe of the liver. During treatment, the position of the catheter was verified and was determined by the physician to be in the correct position. However, post-treatment bremsstrahlung imaging reviewed today on 5/9/2023 indicated some activity was shunted unexpectedly to segments 2 and 3 of the left lobe of the liver. Based on preliminary calculations, this discrepancy could be categorized as a medical event."
* * * RETRACTION FROM ALAN JACKSON TO BILL GOTT AT 0907 EDT ON 05/10/2023 * * *
The following information was provided by the licensee via phone:
Since the exposure was due to shunting, the licensee determined that this event is not reportable in accordance with the licensing guide. This event is being retracted.
Notified R3DO (Feliz-Adorno), NMSS (Rivera-Capella), and NMSS Events Notification.
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.

EN Revision Text: AGREEMENT STATE - DAMAGED GAUGE
The following information was provided by the Utah Division of Waste Management and Radiation Control (the Division) via email:
"During a routine radioactive materials inspection on September 27, 2023, the Division was informed that a gauge was damaged by a piece of equipment which cracked the gauge's casing in May of 2023. The incident was not reported to the Division by the licensee as they believed the event was not reportable. The Division is waiting for additional information pertaining to the incident and will provide an update once the information is received."
Utah Event Report ID number: UT 230007
The following additional information was obtained from the Utah Division of Waste Management and Radiation Control in accordance with Headquarters Operations Officers Report Guidance:
The location is listed as 'Unknown' since the location where the portable gauge was in use when it was damaged is currently unknown but will be provided once that information is received.
* * * RETRACTION ON OCTOBER 4, 2023 AT 1809 EDT FROM SPENCER WICKHAM TO KAREN COTTON * * *
The following information is a summary of an email provided by the Utah Division of Waste Management and Radiation Control (the Division):
After review of additional information provided to the Division by the licensee, it was determined that the gauge only received minor damage to the gauge casing. All equipment of the gauge necessary for safety worked as intended. Therefore the event was not reportable and requested by the Division to be withdrawn.
