AGREEMENT STATE REPORT - DAMAGED MOISTURE-DENSITY GAUGE The following information was received via e-mail: "A Troxler 3430 portable surface moisture-density gauge, S/N 19274, was damaged when it was hit by an excavator at a temporary job site in Shoreline, Washington. Damage included: the screws had been ripped out of the top shell of the gauge, and the metal base of the gauge was cracked on the side. The gauge operator verified that the source rod was intact and retracted into the safe position, and returned the gauge to the licensee's main office for storage, as directed by his radiation safety officer. A Washington Department of Health inspector surveyed the gauge and verified that the neutron and gamma readings were similar to the radiation profile shown in the sealed source and device registry certificate for the gauge. The inspector checked for removable radioactive material contamination on the outside of the gauge by wiping the crack in the side of the base of the gauge, the seam where the top shell joins with the metal base of the gauge, and the source rod opening and bottom plate. No removable contamination was found. The damaged gauge will be shipped for disposal in the near future. "The gauge contained a 40 mCi Am-Be source, S/N 47-14734, and a 4 mCi Cs-137 source, S/N 50-8931." Washington Reference Number: WA-19-028

PRESSURE INSTRUMENT ISOLATION VALVE FOUND IN INCORRECT OPEN POSITION "On October 10, 2019, at approximately 1830 MDT, a responsible individual at Louisiana Energy Services LLC, dba URENCO USA, was informed that on June 5, 2018, at approximately 1600 MDT, pressure instrument isolation valve, 1001-471-1A12, was found open when it should have been shut to maintain the pressure boundary of autoclave 1LS1. The autoclave is used to homogenize UF6 and obtain samples. The autoclave pressure boundary forms IROFS10 [Item Relied on for Safety]. "Prior to the event, on May 31, 2018, annual maintenance was performed on the autoclave as required by the IROFS10 surveillance requirements. Subsequently, a homogenization and UF6 sampling was performed June 1st through June 5th on a 30B cylinder of UF6. During preparations for a subsequent homogenization cycle, valve 1001-471-1A12 was found open. The valve should have remained closed from the previous homogenization. There was not an initiating event (no release of UF6) and no initiation of an accident sequence. The valve has been shut and the IROFS boundary has been restored. The plant is in a safe configuration. "This event has been identified in UUSA's corrective action program as EV 133619 and a causal investigation is planned."

AGREEMENT STATE REPORT - MISADMINISTRATION OF Y-90 MICROSPHERES The following information was received from the Texas Department of State Health Services (the Agency) via E-mail: "On October 11, 2019, the Agency was contacted by the licensee's radiation safety officer (RSO) who reported a medical event had occurred at their facility. The RSO stated that the event involved a patient who was to receive a treatment with yttrium-90 microspheres. The administering physician had difficulties setting up the injection apparatus and installed an additional piece of tubing in-line with the injection tubing. Because of the additional length of tubing, the patient received only five percent of the prescribed activity. The RSO stated there would be no adverse effects on the patient. The RSO stated both the patient and the prescribing physician have been notified of the error. The RSO stated that the bulk of the microspheres (activity) remained in the tubing and no contamination was found in the area where the treatment occurred. The RSO stated the physician decided they would perform the procedure again and use the activity needed to bring total activity administered to the activity initially prescribed. Additional information will be provided as it is received in accordance with SA-300." Texas Incident No.: I-9721 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.

INADVERTENT OPENING OF MAIN TURBINE BYPASS VALVES POTENTIONALLY AFFECTED SAFE SHUTDOWN CAPABILITY "At 0207 [CDT], the Bypass Electro-Hydraulic Control (EHC) system was secured for planned maintenance. When the Bypass EHC pumps were secured, both of the Main Turbine Bypass Valves unexpectedly opened to approximately 4.5 percent. Plant parameters indicated no impact to Turbine Control Valve position, Reactor Pressure, Turbine First Stage Pressure, or Main Steam Line flows. There were no other abnormal indications noted. With the Turbine Bypass Valves partially open, there is a potential to affect instrumentation that trips on high Turbine First Stage Pressure. Therefore, this event is being reported as a potential loss of Safety Function. At 0256, the Bypass EHC system pumps were restored and the Turbine Bypass Valves Closed. "No radiological releases have occurred due to this event from the unit." The licensee has notified the NRC Resident Inspector.
