| AGREEMENT STATE REPORT - STOLEN DENSITY GAUGE The following is a synopsis of a event reported by the state of Texas via email and phone call: On February 24, 2020, the Texas Department of State Health Services (Agency) was contacted by the Braun Intertec Corporation RSO to report a stolen moisture density gauge. The gauge was last seen on February 19, 2020 at the end of work in McKinney Texas. It was locked in a box in the back of a truck which was then driven to Euless, Texas where it reported to stay until February 24, 2020. The truck was then driven to a jobsite in Richardson, TX on February 24, 2020 at which point the employee realized that the locks were gone and the moisture density gauge was removed from the box in the back of the truck. Euless Police were notified. The activity for the density gauge is estimated to be 10 mCi Cs-137 and 40 mCi of Am241/Be. An investigation into this event is ongoing. More information will be provided when obtained in accordance with SA- 300. Texas Incident number: 9746 THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

| AGREEMENT STATE REPORT - STOLEN FLUORESCENCE ANALYZER EQUIPMENT The following report was received from the state of Illinois via email: "The Agency [Illinois Emergency Management Agency] was notified by the Radiation Safety Officer (RSO) of the Illinois Department of Public Health (IDPH) that an XRF [X-ray fluorescence] instrument was stolen the morning of 2/21/20 in Peoria, IL. The RSO was made aware of the theft at approximately 1030 [CST] today. The vehicle had been parked overnight in the driveway of an IDPH employee who works out of the Peoria field office (site #2 on IL license). The gauge was locked in the trunk, in addition to having a lock on the case itself. However, the vehicle had been left running while the user went back into their home to retrieve a laptop, and upon their return they realized the vehicle had been stolen. Peoria Police were notified and informed of the instrument and radiation source in the trunk. The XRF is model XLP303A, serial number 14472; and the source serial number is TR2743. The IDPH will keep the Agency updated if they receive any additional information related to the vehicle or XRF instrument. The theft appears to be incidental to the theft of a vehicle and not an intentional diversion of radioactive material. The sources contained within these devices are IAEA category 5, meaning no one could be permanently injured and the amount of radioactive material, even if dispersed, could not permanently injure anyone." Illinois report no.: IL200006 Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

| AGREEMENT STATE REPORT - PATIENT UNDERDOSE The following was received from the state of Florida via email: "On 24 Feb. 2020, at 1315 EST, an underdose of radiation to a patient receiving skin therapy occurred. The patient was scheduled to receive five fractions, at 7.5 grays per fraction, on five different parts of the left hand per fraction. On the first dose of the first fraction, it was observed that catheter numbers 1 - 15 were reversed, causing an underdose to the patient. No Authorized Users were exposed to the source or otherwise contaminated. The licensee has agreed to submit further information on 26 Feb 2020. Since the cause of this incident is machine generated, in accordance with BRC [State of Florida Bureau of Radiation Control] procedures, it is not being given an incident number, and is being forwarded to ERCX [the X-Ray Machine Section of the BRC]." 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. |

| EMERGENCY DIESEL GENERATOR ACTUATION "At 0416 CST on March 3, 2020, with Browns Ferry Unit 3 in Mode 5, there was a partial loss of 161kV power due to a trip and re-closure of the feeder breaker supplying the Common Station Service Transformer (CSST) A. Unit 3 lost power to the 1A Start Bus and the 3A Unit Board, which supplies power to the 3EA and 3EB 4kV Shutdown Boards. The loss of the 4kV Shutdown Boards resulted in an auto actuation of the 3A and 3B Emergency Diesel Generators (EDG). The 3C EDG and 3EC 4kV Shutdown Board were removed from service for maintenance at the time of the loss of power, and the 3ED 4kV Shutdown Board continued to be powered from the 3B Unit Board. "All systems responded as expected for the loss of power. "This event requires an 8 hour report per 10 CFR 50.72(b)(3)(iv)(A). "There was no impact to the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified." The partial loss of power was caused by a storm in the area. Offsite power has been restored to the CSST and the EDGs have been secured. |

| REACTOR TRIP DUE TO LOW STEAM GENERATOR LEVEL "At 2050 MST on March 3, 2020, Unit 2 reactor automatically tripped on Low Steam Generator (SG) Number 1 level signal from the Reactor Protection System. The low SG level occurred as the result of a trip of both Main Feedwater Pumps, which tripped during restoration of power to the Main Feedwater Pump Lube oil control panel. Auxiliary Feedwater (AFAS-1 and AFAS-2) actuated due to low SG levels in both SG post reactor trip as designed. This event is being reported as a reactor protection system and a specified system actuation in accordance with the reporting criteria of 10 CFR 50.72(b)(2)(iv)(B) and 10 CFR 50.72(b)(3)(iv)(A). "Following the reactor trip, all [control element assemblies] CEAs inserted fully into the core. All systems operated as expected. No emergency plan classification was required per the Emergency Plan. Safety related busses remained powered during the event from offsite power and the offsite power grid is stable. Unit 2 is stable and in Mode 3. Steam Generators are being fed via the class 1 E powered motor driven auxiliary feedwater pump. "The NRC Senior Resident Inspector has been informed." Units 1 and 3 were unaffected by the trip and remain at 100 percent power. |
