MANUAL REACTOR TRIP AND AUTOMATIC AUXILIARY FEEDWATER ACTUATION

The following information was provided by the licensee via email:

"At 0724 EDT on 6/15/2022, with Unit 1 in Mode 1 at 100 percent power, the reactor was manually tripped due to lowering Steam Generator levels due to a secondary plant perturbation in the Heater Drain System. All control rods fully inserted into the core and the Auxiliary Feedwater System automatically started as designed in response to the full power reactor trip. The trip was not complex, with all systems responding normally post-trip. There was no equipment inoperable prior to the event that contributed to the reactor trip or adversely impacted plant response.

"Operations responded and stabilized the plant. Decay heat is being removed by discharging steam to the main condenser using the condenser steam dump valves. Unit 2 is not affected and remains at 100 percent power and stable.

"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, this 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 Auxiliary Feedwater System.

"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

AGREEMENT STATE REPORT - STOLEN PORTABLE NUCLEAR GAUGE

The following information was received from the State of Nevada via email:

"At approximately 1350 PDT, the RSO/CEO for IQC Southwest LLC, 00-11-0745-01 notified the Nevada Radiation Control Program (NRCP) that a Portable Nuclear Gauge (PNG) had been stolen from a work site located near the intersection of Sierra Vista and Paradise Road working off of Paradise Road in Las Vegas, Nevada. In addition, Las Vegas Metro Police Department was on scene and taking a report during the Radiation Safety Officers (RSO) notification call to the NRCP.

"The RSO stated that they had video of the theft as it occurred. An unknown (possibly transient) individual walked through the work site, picked up the gauge and walked off, appearing to hide the gauge with his body while the Authorized User (AU) was getting material from his vehicle. The source rod was not locked when the gauge was taken.

"The gauge was a Troxler model 4640-B with a 9 mCi Cs-137 source.

"An incident inspection will be performed June 16, 2022 by the NRCP."

Nevada Item Number: NV220006

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.
