AUTOMATIC REACTOR SCRAM CAUSED BY MAIN TRANSFORMER TRIP
"At 0651 [PDT] on May 18th, 2018, Columbia Generating station experienced a Main Transformer trip, that caused a Reactor Scram. Reactor Power, Pressure and Level were maintained as expected for this condition. MS-RV-1A (Safety Relief Valve) and MS-RV-1B (Safety Relief Valve) opened on reactor high pressure during the initial transient. MS-RV-1B appeared to remain open after pressure lowered below the reset point. The operating crew removed power supply fuses for MS-RV-1B and it currently indicates intermediate position. SRV (Safety Relief Valve) tail pipe temperatures indicate all valves are closed. Suppression pool level and temperature have remained steady within normal operating levels.
"All control rods inserted and reactor power is being maintained subcritical.
"RPV (Reactor Pressure Vessel) water level is being maintained with condensate and feed system with startup flow control valves in automatic. Reactor Pressure is being maintained with the Turbine Bypass valves controlling in automatic. The main condenser is the heat sink.
"No ECCS (Emergency Core Cooling Systems) systems actuated or injected; the EOC-RPT (End of Cycle-Recirculation Pump Trip) and RPS (Reactor Protection System) systems actuated causing a trip of the RRC pumps and a reactor scram.
"Core recirculation is being maintained with RRC-P-1A (Reactor Recirculation Pump) running.
"No release has occurred.
"At this time there will be no notifications to state, local or other public agencies.
"The NRC Senior Resident has been notified.
"The cause of the event is currently under investigation. Plant conditions are stable."
The plant is in its normal electrical alignment and offsite power is available to the site.

AGREEMENT STATE - POTENTIAL UNPLANNED CONTAMINATION
The following was received from the State of Texas via email:
"On May 11, 2018, the Agency [Texas Department of State Health Services] was notified by the licensee that an event had occurred. The licensee stated that a patient had been treated with I-131 for thyroid cancer on May 4, 2018. The patient was instructed on the procedure, restrictions, and their responsibility after the treatment. The patient signed a document stating they understood the instructions. The patient was scheduled to return on May 11, 2018, for a whole body scan. The patient was discharged after the radionuclide was administered.
"On May 11, 2018, the patient failed to show up for his 1000 hours appointment. At 1100 hours, the nurse (nurse one) working the scanner area received a phone call from a floor nurse. The floor nurse asked if they had an appointment for the patient in this event. Nurse one stated they did, but he failed to show up for the appointment. The floor nurse stated that the individual was in their treatment area. Nurse one asked how long he had been there and the floor nurse stated he had been brought to them 4 days prior with an injury from a fall. Nurse one asked why radiology had not been informed and the floor nurse stated they were not aware of his previous procedure.
"The licensee surveyed the patient and found they were reading above background. The licensee determined areas of the hospital outside the patient's room the patient would have been in and surveyed them. No contamination was found. The licensee removed all material from the patient's room and moved it to its decay room for storage. Access to the patient's room was restricted until it decays to levels not distinguishable from background. The licensee established controls to prevent any further contamination resulting from the patient. The patient was discharged from the hospital to the rehab facility on May 14, 2018.
"The Agency was not aware that access was restricted to the patient's room until the written report was reviewed on May 18, 2018. Additional information will be provided as it is received in accordance SA-300."

AGREEMENT STATE - UNATTENDED RADIOGRAPHY CAMERA
The following was received from the State of California via email:
"On 05/18/18, RSO [radiation safety officer] contacted RHB [Radiologic Health Branch] to report an incident where one of their radiographic exposure devices was left unattended at a job site inside a refinery. Licensee reported that due to a miscommunication, around 6:00 am [PDT] on 05/18/18 a camera was left unattended in an uncontrolled unit within the Chevron Refinery, in Richmond, CA, for several hours before it was discovered and placed it under licensee's control. The camera involved is a Model Ir-100, S/N 4850, Source S/N 223D containing 86 Ci of Ir-192. RHB will be following up on this investigation. (Note: Currently, Qualspec, LLC is in the process of merging with another licensee, TEAM Industrial Services)"
California ID # 051818
THIS MATERIAL EVENT CONTAINS A "CATEGORY 2" LEVEL OF RADIOACTIVE MATERIAL
Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.
