MANUAL REACTOR TRIP DUE TO DROPPED CONTROL ROD
"On August 13, 2020, at 0938 EDT, with Harris Nuclear Plant Unit 1 in Mode 1 at 100 percent power, a control rod dropped during control rod testing. This is considered to be an unanalyzed condition and requires a manual reactor trip in accordance with plant procedure. All safety systems functioned as expected. Auxiliary Feedwater started as designed and was secured. Steam generator levels are being maintained by Main Feedwater through the feedwater regulator bypass valves. Decay heat is being removed by using the condenser steam dump flow path. Due to the RPS actuation, this event is being reported as a four hour non-emergency notification per 10 CFR 50.72(b)(2)(iv)(B). Due to the unanalyzed condition and unplanned Auxiliary Feedwater actuation, this event is also being reported as an eight hour non-emergency notification per 10 CFR 50.72(b)(3)(ii)(B) and 10 CFR 50.72(b)(3)(iv)(A).
"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

EN Revision Text: AGREEMENT STATE REPORT - FIRE INVOLVING OIL WELL LOGGING SOURCE
"On August 13, 2020, the Agency [Texas Department of State Health Services] was contacted by the Nuclear Regulatory Agency (NRC) and notified that they had been contacted by a State of Texas licensee. The NRC still had the licensee on their bridge line and tied the Agency into the call with the licensee. The licensee's radiation safety officer (RSO) reported that one of their well service blending trucks was engaged in a fire. The well is located near Mentone, Texas. The truck has a TN model 5190 nuclear gauge containing a 200 milliCurie cesium - 137 source installed on the piping system. The gauge was purchased in December 2019. At the time of the call (2121 CDT) the fire was still burning, and a fire department was on scene. The RSO believed the fire department was aware of the source. The RSO stated all their personnel had been evacuated from the scene of the fire. There is no way to know the status of the gauge shielding or of the source. The RSO agreed to contact the Agency when the fire was put out, and after completing a survey of the gauge. Additional information will be provided as it is received in accordance with SA-300."
TX Incident #: I-9783
Notified DHS SWO, DOE Ops Center, FEMA Ops Center, HHS Ops Center, CISA Central, USDA Ops Center, EPA Emergency Ops Center, FDA Emergency Ops Center (email), FEMA NWC (email), DHS Nuclear SSA (email), and FEMA NRCC SASC (email).
* * * RETRACTION ON 8/14/2020 AT 2051 EDT FROM ART TUCKER TO KERBY SCALES * * *
The following retraction was received from the state of Texas via email:
"On August 14, 2020, the licensee reported that after the fire was extinguished it found that the fire did not reach the gauge or equipment around it. This included electrical wiring and rubber hoses which showed no damage from the fire. A portion of the equipment the gauge was mounted to did have some fire damage. An Agency radioactive material inspector went to the site and performed a dose rate survey on the gauge. Based on this survey, it does not appear there was any damage to the gauge shielding. There was a second gauge at the site, but it was not anywhere near the area of the fire and was not affected. It was also surveyed and did not appear to have had any damage. The dose rates taken on the gauges were similar. Based on this information this event does not meet the reporting criteria and is therefore retracted. The licensee has performed a leak test of the gauge and if the results are greater than the limit it will be reported in accordance with SA-30."
