AUTOMATIC REACTOR TRIP ON OVER POWER DELTA TEMPERATURE
"At 0925 EDT, on September 8, 2020, with Unit 1 in Mode 1 at 100 percent power, the reactor automatically tripped on Overpower Delta Temperature. Unit 1 Channel 1 Overpower Delta Temperature was tripped as a planned evolution when an inadvertent Unit 1 Channel 2 Overpower Delta Temperature signal was received. This resulted in an automatic reactor trip. The trip was not complex, with all systems responding normally. Because of the reactor trip, the Auxiliary Feedwater (AFW) System actuated as expected due to on ATWS Mitigation System Actuation Circuitry (AMSAC) signal. Unit 2 is not affected.
"Operations responded and stabilized the plant. Decay heat is being removed by discharging steam to the main condenser using the condenser steam dump valves.
"Due to the Reactor Protection System (RPS) actuation while critical, this event is being reported as a 4-hour, non-emergency notification per 10 CFR 50.72(b)(2)(iv)(B). This event is also being reported as an 8-hour non-emergency notification per 10 CFR 50.72(b)(3)(iv)(A) as an event that results in a valid actuation of the AFW system.
"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

REPORT OF OFFSITE NOTIFICATION DUE TO IMPAIRMENT OF FIRE SUPPRESSION SYSTEM
"At approximately 1015 (EDT) on September 8th, 2020, the New Hanover County Deputy Fire Marshal was notified per State code requirements that the fire suppression system encompassing a part of the Fuel Manufacturing Operation (FMO) was impaired due to planned piping replacement. Additional compensatory measures were enacted. The system was restored at approximately 1750 (EDT) yesterday (9/8/2020) and the Deputy Fire Marshal informed of restoration. Because the New Hanover County Deputy Fire Marshal was notified, a concurrent notification to the NRC Operations Center is being made per 10 CFR 70, Appendix A(c)."
NRC Region 2 and the State of North Carolina will be notified by the licensee.

AGREEMENT STATE REPORT - LOST AND RECOVERED CAMERA
The following was received from Texas Department of Health Services (the agency) via email:
"On September 9, 2020, the Agency was notified by the licensee's radiation safety officer (RSO) that on September 8, 2020, one of his crews lost a QSA 880D exposure device containing a 38.1 Curie iridium-192 source. The radiography crew had placed the exposure device on the tailgate of their truck at the licensee's location. The crew drove away from the site with the exposure device still on the tailgate. The device fell off the truck a short distance from the licensee's location. A second crew left the licensee's location a short time (10 minutes) later and found the device on the pavement. The second crew performed a radiation survey of the device and found the radiation levels to be normal and the source was still fully shielded. The second crew returned the device to the licensee's location. The device was inspected and did not appear to be damaged. The licensee has sent the device to the manufacturer for inspection. Additional information has been requested from the licensee. Additional information will be provided as it is received in accordance with SA-300. "
Texas Incident Number: I-9798
THIS MATERIAL EVENT CONTAINS A "CATEGORY 2" LEVEL OF RADIOACTIVE MATERIAL
Category 2 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 a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.
