AUTOMATIC REACTOR SCRAM DUE TO TURBINE TRIP ON HIGH REACTOR WATER LEVEL
The following information was provided by the licensee via fax or email:
"At 0803 EDT on 7/12/2022, with the Unit 2 in Mode 1 at 100% power, an automatic scram was received on Unit 2 following a turbine trip due to high reactor water level. The trip was uncomplicated with all systems responding normally post trip. All rods inserted to their full-in positions.
"Due to the Reactor Protection System actuation while critical, this event is being reported as a four-hour, non-emergency notification per 10 CFR 50.72(b)(2)(iv)(B).
"The cause of the transient is under investigation.
"Operations responded using the Emergency Operating Procedure and stabilized the plant in Mode 3. Decay heat is being removed using the steam bypass valves to the condenser and the safety relief valves did not lift as a result of the trip. Reactor vessel inventory and pressure are being maintained in normal control bands.
"Unit 3 was not affected by this transient.
"There was no impact to the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

EN Revision Text: AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE
The following information was provided via email:
"On July 12, 2022, the licensee notified the Agency that around 1230 CDT, a Humboldt 5001EZ Moisture Density Gauge containing a 40 milliCurie Americium-241 source and a 10 milliCurie Cesium-137 source was stolen out of the back of a company truck. The licensee reported that the technician returned to the site office, he unlocked the moisture density gauge transit case. He then got distracted and went into the office. When he went back outside the case was still chained to the truck but when he opened the case the gauge was missing. The gauge was unlocked. LLE [Local Law Enforcement] was notified. Additional information will be provided as it is received in accordance with SA-300."
Texas Incident number: 9939
* * * UPDATE ON 2/9/23 AT 0946 EST FROM TEXAS DEPT OF STATE HEALTH SERVICES (THE AGENCY) TO KAREN COTTON * * *
"On July 12, 2022, the licensee notified the Agency that a Humboldt 5001EZ moisture density gauge, serial number 3716, was stolen out of the transport case in the back of a pickup at the licensee's site office. The gauge contained an 10 millicurie cesium-137 source and a 40 millicurie americium-241/beryllium source. The technician had unlocked the transport case, got distracted and went into the office. When he came back outside the gauge was no longer in the case. The investigation was completed on August 17, 2022, and two violations were cited. On February 2, 2023, the Agency was notified by the NRC that a Moisture Density Gauge was posted for sale on eBay. The Agency contacted the seller and determined that it was the stolen gauge and the licensee retrieved the gauge on February 8, 2023. The seller found the gauge in a dumpster behind a retail store. The gauge was inspected and a leak test was conducted. The gauge operates properly."
Notified R4DO (Gaddy), NMSS Events Notification, ILTAB, and CNSNS (Mexico) via email.
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.

HIGH PRESSURE COOLANT INJECTION INOPERABLE
The following information was provided by the licensee via fax or email:
"At 0917 CDT on 7/12/2022, during the performance of U1 [Unit 1] High Pressure Coolant Injection (HPCI) rated flow test, the 1-FCV-73-19 (HPCI governor valve) failed to operate as expected. This condition results in U1 HPCI being inoperable; therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v). The Automatic Depressurization System (ADS) and Reactor Core Isolation Cooling (RCIC) system remain operable.
"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified.
"U1 entered TS LCO 3.5.1 Condition C, 14-day Shutdown LCO [Limiting Condition for Operation], due to the HPCI inoperability."
