AGREEMENT STATE REPORT - FIXED PROCESS GAUGE SHUTTER MALFUNCTION

The following was received from the Commonwealth of Kentucky via email:

"The KY RHB [Kentucky Radiation Health Branch] was notified via email on 2/6/2020 (1559 EST) by a representative from specifically licensed facility, Big Rivers Electric Corp., that at 0715 on Thursday, 2/6/2020, one fixed gauging device (Kay Ray Model 7062BP, Serial Number 20086), containing 100 milliCuries Cs-137 (source serial No. 17400V; assay date 10/30/1985) had developed a potential problem while the shutter arm was moving freely. Survey results showed that the shutter remained in the shut position. The gauge is mounted on a pipe, and manned entry is not of concern, and the plant personnel have been notified that there is no access allowed to the affected pipe. All operational and maintenance activities will be delayed until the device has been removed for repair by a service provider. The licensee will be contacting a licensed service provider to remediate this situation. This is being reported under 10 CFR 30.50(b)(2)."

AGREEMENT STATE REPORT - MEDICAL EVENT

The following was received from the state of Minnesota via email:

"Lu-177 administration was performed on February 4, 2020. The administration team did not start the patient on amino acids prior to the administration. Upon discovery of the error, the acids were started. This resulted in an unintended dose to the kidneys. The Radiation Safety Officer (RSO) and staff were notified on February 5, 2020. They determined it was a medical event on February 7, 2020 at 0930 CST. The event was reported to the Minnesota Department of Health (MDH) at 1000 CST on February 7, 2020. The intended dose to the kidney was 490 Rem. The delivered dose to the kidney was 740 Rem (this was their 'best case scenario' calculation). This would fall under 4731.4525 Subpart 1 Item C.: 'a dose to the skin or an organ or tissue other than the treatment site that exceeds 50 Rem and exceeds 50 percent of the dose expected from the administration defined in the written directive.'"

This event is still under investigation with MDH.

Minnesota Event Report ID: MN200002

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 - LOST OR MISSING SOURCE

The following is a synopses of the Louisiana Department of Environmental Quality email notification to the NRC:

On February 7, 2020 at 1012 EST, the Alpha-Omega Services, Inc., Radiation Safety Officer, contacted the Louisiana Department of Environmental Quality by email to report that a High Dose Rate Ir-192 source cannot be located. The source was in transit to Golden, Colorado and was last located at the Common Carrier hub in Memphis, Tennessee. The source serial number is 02-01-2012-001-012220-11606-02. The current activity of the Ir-192 source is 9.987 Ci.

Event Report ID No.: LA20200002

THIS MATERIAL EVENT CONTAINS A "CATEGORY 3" LEVEL OF RADIOACTIVE MATERIAL

Category 3 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 some hours. It could possibly - although it is unlikely - be fatal to be close to this amount of unshielded radioactive material for a period of days to weeks. These sources are typically used in practices such as fixed industrial gauges involving high activity sources (for example: level gauges, dredger gauges, conveyor gauges and spinning pipe gauges) and well logging.

AGREEMENT STATE REPORT - REPORTABLE EQUIPMENT FAILURE

The following information was received via E-mail:

"A reportable equipment failure occurred on February 22, 2019 at a panoramic irradiator licensee in Libertyville, IL. The equipment failure was not reported to Illinois Emergency Management Agency (IEMA), but identified during a February 6, 2020 routine inspection. The affected equipment has since been repaired and no impacts to health or security were identified.

"IEMA inspectors conducted a routine inspection at Isomedix Operations d/b/a Steris, Libertyville location, on February 6, 2020. During a review of licensee files, it was determined that on the evening of February 22, 2019, required safety equipment became disabled as a result of the cell flooding. This is reportable, at a minimum, under 32 Ill. Adm. Code 340.1220c2. Inspection findings indicate that on or about 1817 CST February 22, 2019, a coupler on a 2 inch sprinkler line in the maze of the cell broke during processing. The cell consequently flooded and began to flood the warehouse. An emergency console stop was executed at approximately 1821 CST and both racks submerged. At 1824 CST, the pool high water alarm was tripped. Inspector review of the console event log indicates within the next 80 minutes the smoke detector, exhaust fans, collision bar, inside roof plug, low air pressure, high temperature, main panel communications and loss of 110 VAC and 24VDC faults were logged.

"It was also noted that at 2024 CST on February 22, 2019, the source racks were moved back up. At 2024 CST, the deionizer radiation monitor alarmed. A number of alarms and faults continued until approximately 1121 CST on 2/23/19. Reportedly, up to four inches of water covered the pool and the entirety of the warehouse. The fire department was needed to shut off the main feeding the sprinklers. Inspection findings indicate, at a minimum, high and low water monitors as well as the deionizer radiation monitor were disabled due to the wiring being flooded and shorted in the trough. The wiring for multiple components were replaced and plumbers contracted to repair the sprinkler system the following day. The licensee has moved to a manually initiated dry fire suppression system. Dosimetry was evaluated and no unusual exposures noted. Interviews of staff involved indicate security systems were not impacted. Leak tests were performed on February 22, 2019. This incident remains under investigation.

"There is no evidence of intentional disruption of safety or security systems."

MANUAL REACTOR SCRAM DUE TO RISING CONDENSER BACKPRESSURE

"At 0025 EST on February 14, 2020, Susquehanna Steam Electric Station Unit 2 reactor was manually scrammed due to rising Main Condenser backpressure caused by a loss of the Unit 2 Offgas Recombiner.

"Unit 2 reactor was being operated at maximum facility output, approximately 98% RTP, when at 0012 EST, Unit 2 Recombiner 0C145 Panel Trouble and 2C198 HWC Panel Trouble alarms were received along with rising Main Condenser backpressure. Initial Main Condenser backpressure was 2.6 in HgA and was rising at approximately 0.3 HgA/min. A Recirc Lim 2 was inserted to lower reactor power and condenser backpressure continued to rise following the reduction in reactor power. A manual scram was inserted at 0025 EST by placing the Mode Switch to Shutdown when condenser backpressure rose to 6 in HgA. All control rods inserted. Reactor water level lowered to -30 inches causing Level 3 (+13 inches) isolation and partial (Division 2) Level 2 (-38 inches) isolation. No ECCS actuations occurred and RCIC initiated. The Operations crew subsequently maintained reactor water level at the normal operating band using Reactor Feed Water. No steam relief valves opened. The Reactor Recirculation Pumps remained in service.

"The reactor is currently stable in Mode 3. Investigation into the cause of the loss of Unit 2 recombiner is underway.

"The NRC Senior Resident Inspector was notified. A voluntary notification to PEMA and press release will occur."
