AGREEMENT STATE REPORT - MEDICAL EVENT

The following was received from the Arizona Department of Health Services (the Department) via email:

"On June 12, 2020, the Department received notification from the licensee of a possible medical event involving an I-125 eye plaque. A patient was implanted with an eye plaque on June 4, with a prescribed dose of 85 Gy. On June 8, the patient had a stroke and was admitted to St. Joseph's Medical Center. Once the patient was able to be transported, they were transported back to the Mayo Clinic Hospital on June 9. It was then determined that the patient was not strong enough to endure the procedure for removing the eye plaque. The eye plaque was finally removed on June 11 and the final dose to the tumor was 123.5 Gy or 145.3 percent of the prescription.

"The Department has requested additional information and continues to investigate the event."

Arizona Incident 20-010

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.

UNPLANNED TECHNICAL SUPPORT CENTER VENTILATION MAINTENANCE

"At 2100 on June 21, 2020, a condition was discovered which will require corrective maintenance activities to be performed on the Technical Support Center (TSC) HVAC. The work will include repair of the Condensing Unit system. The estimated duration of repair is unknown at this time.

"If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures unless the TSC becomes uninhabitable. If relocation of the TSC becomes necessary, the Emergency Director will relocate the TSC staff to the alternate facility.

"This is an eight-hour, non-emergency notification for a loss of Emergency Assessment Capability. This event is reportable in accordance with 10 CFR 50.72(b)(3)(xiii) because the discovered condition of the TSC affects the functionality of an emergency response facility.

"There was no impact on the health and safety of the public or plant personnel.

"The NRC Resident Inspector has been notified."
