AUTOMATIC REACTOR TRIP OF UNIT 2 DUE TO A LOAD REJECTION
"At 1006 [PST], on December 1, 2018, with Unit 2 at 100 percent power, the reactor automatically tripped due to a load rejection from the 500 kV offsite electrical system.
"Operations responded and stabilized the plant. Decay heat is being removed by the Main Steam system to the main condenser using the steam dump valves. The cause of the load rejection is currently under investigation.
"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). Additionally, due to the actuation of the Auxiliary Feedwater System, as expected, this event is being reported per 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 Senior Resident Inspector was notified. A press release is planned for this event."
All control rods fully inserted and the trip was uncomplicated. There was no effect on Unit 1.

TECHNICAL SPECIFICATION VIOLATION
Violation of Technical Specification 6.1.3, which requires the minimum staffing when the reactor is not secured to be a licensed reactor operator, and another individual.
The key was inserted at 1316 PST and removed at 1325 PST and reinserted at 1327 PST and removed at 1331 PST on December 1, 2018. The reactor operator was trying to complete the reactor startup checklist, but was alone. No rods were withdrawn during this period.

LOST THEN FOUND TROXLER MOISTURE DENSITY GAUGE
The following was received from the State of Illinois by email:
"The licensee contacted the agency on 12/1/18 at approximately 1800 [CST] to report that a tornado had struck their portable gauge storage location at 1615 [CST]. Licensee was unable to locate the gauge at the time of the call. Agency inspectors arrived at the location at 1945 [CST] and began surveys. The Troxler gauge was located in its transport case beneath the rubble of the destroyed building. The following morning, an excavator was utilized to remove the debris and gain access to the gauge. Both the gauge and the transport case were undamaged. The gauge was secured by two physical barriers in another building on site. Leak tests will be taken the week of 12/3/18 and the gauge is removed from service until leak test results are received. The licensee will be submitting an amendment request for a new storage location. Pending no further developments, this matter is considered closed."
IL Event Item Number: IL180040
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.
