| AGREEMENT STATE REPORT - LOST GAUGE The following is a summary of an email received from the state of Florida: At approximately 2030 EDT on 5/11/2020, a Troxler density gauge (serial number: 28189) fell off the back of one of the licensee's trucks because the chain securing the gauge's case was not properly attached. The gauge has not been located at this time. The gauge contains an 8 milliCurie Cs-137 source and a 40 milliCurie Am-241 source. Nearby police departments, the US Department of Transportation, and the Florida Department of Environmental Protection have all been notified. Florida Incident Number: FL20-057 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 - PATIENT UNDERDOSE The following is a summary of an email received from the state of Florida: A patient underdose occurred during a Y-90 TheraSphere treatment at the licensee on 5/11/20. The patient was prescribed 2.48 GBq of Y-90, but only received 1.86 GBq (75% of the prescribed dose). The underdose was caused by the catheter being displaced during patient movement. Florida Incident Number: FL20-056 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 - RADIATION LEVEL ON PACKAGE EXCEEDS DOT LIMITS The following was received via email: "On May 11, 2020 the licensee received a 10 gallon drum that fell outside of the Department of Transportation (DOT) dose rate level limitations. The package came from Cadman Materials, Inc. in Vancouver WA. The material inside is a gauge with a Cs-137 sealed source inside with an activity of 100 millicuries (3700 MBq). The package was shipped as UN2915, Radioactive Material Type A Package with Yellow-II labeling and a Transport Index of 0.1.

| AGREEMENT STATE REPORT - NUCLEAR GAUGE BROKEN LOCKING MECHANISM The following was received by the state of Texas via email: "On May 12, 2020, the Agency [Texas Department of State Health Services] was notified by the licensee that the locking mechanism on a Endress Houser nuclear gauge model number FQG61 had broken off the gauge housing preventing them from locking the shutter in the closed position. The gauge contains a 100 millicurie (original activity) cesium-137 source. The shutter operates normally. The licensee reported the gauge will not present an exposure risk to any individual. The licensee stated it is in the process of trying to schedule repairs to the gauge. Additional information will be provided as it is received in accordance with SA 300."

A Notification of Unusual Event was subsequently declared at 1930 EDT. The reactor was in a shutdown condition at the time of the event and has been due to COVID-19. The licensee is monitoring the flood situation in the area and licensee personnel have responded to the site. The NRC remains in the normal mode of operations. Notified DHS SWO, FEMA Operations Center, CISA IOCC, FEMA NWC (email), DHS Nuclear SSA (email), and FEMA NRCC SASC (email). * * * UPDATE ON 5/21/2020 AT 0850 EDT FROM SIAKA YUSUF TO JEFFREY WHITED * * * At 0850 EDT on May 21, 2020, the Dow Chemical Company TRIGA Reactor Terminated the Notification of Unusual Event. The event was terminated after flood water receded. The flood water receded faster than was expected. As stated, the reactor was in a shutdown condition at the time of the event. There was no effect on the reactor due to the flood water.

| AUTOMATIC ACTUATION OF EMERGENCY DIESEL GENERATORS "At 0521 EDT on May 20, 2020, with Unit 2 in Mode 3 at 0 percent power and Unit 1 defueled, an actuation of the Emergency Diesel Generator (EDG) System occurred while transferring the 1B-B 6.9kV Shutdown Board (SDBD) from the maintenance feed to its normal power supply. The reason for the 1B-B 6.9kV SDBD failing to transfer to the normal power supply is under investigation. The EDGs automatically started as designed when a valid actuation signal was received. "The event is being reported in accordance with 10 CFR 50.72(b)(3)(iv)(A) as an event that results in a valid actuation of the EDGs. "There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified." |

| PART 21 REPORT - INADEQUATE DEDICATION OF REPLACEMENT THERMOCOUPLES The following is a summary from the Diablo Canyon Part 21 Report submitted: On May 18, 2020, Pacific Gas and Electric (PG&E) completed its evaluation of a deviation concerning commercial-grade thermocouples dedicated at Diablo Canyon Power Plant. The original defect was discovered on April 10, 2020 during bench testing where two separate thermocouples exhibited leakage during static pressure testing. The two thermocouples were tested as part of a spare safety-related pump motor refurbishment. Upon subsequent review, it was identified that a pressure boundary test had not been required as part of the dedication process, but should have for its safety-related application. These components were not installed in the plant and there was no risk to the health and safety of the public. Thermocouples from the same batch have been quarantined to prevent installation, and it has been confirmed that none of the suspect batch of thermocouples have been installed in the plant. The thermocouple replacement part evaluation has been revised to include a pressure boundary test as part of the commercial-grade dedication prior to acceptance. Thermocouple Make and Model: March Bellofram 3060-2-JJ-2-13.00-0-1-000 The NRC Resident Inspectors have been notified. This report only affects Diablo Canyon Power Plant.
