AUTOMATIC REACTOR SCRAM
The following information was provided by the licensee via phone and email:
"At 1242 [EST] on 05 January 2023, with the Unit in Mode 1 at 99 percent power, the reactor automatically tripped on low Reactor Pressure Vessel level while restoring power to Digital Feedwater Control Stations when there was a perturbation to the level controls. The reason for perturbation is unknown at this time. The trip was not complex, with all systems responding normally post trip. Operations responded and stabilized the plant. High pressure core spray was manually initiated in accordance with site procedures. Reactor water level is being maintained via the Feedwater System. Decay heat is being removed by the Main Condenser.
"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)(A) and 10 CFR 50.72(b)(2)(iv)(B).
"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

SAFETY ITEM UNAVAILABLE
The following information was provided by the licensee via email:
"On 1/5/2023 at 1105 [MST], the control room received a call that a crane operator had operated the crane over a strap laying on the crane track. The initial inspection of the crane determined that a component of the crane had been damaged. The component was identified as a device to sweep debris from the crane rails and was not an [item relied on for safety] IROFS related component. At 0245 [MST], a Shift Manager inspected the crane and determined that the damaged component was part of IROFS27e [This IROFS is introduced for Separation Building Modules (SBM) for seismic, tornado, high wind, roof snow load, roof ponding, and site flooding due to local intense precipitation. Design features of the SBMs are to withstand loadings from these natural phenomena.] The component restrains the crane during a natural phenomena hazard. IROFS27e is an IROFS that is required to be available and reliable. An engineering analysis was initiated to determine if the crane would perform its safety function with the damaged component. Although the analysis is in progress, UUSA is reporting this event per 10 CFR 70. Appendix A (a)(4).
"There were no injured personnel and no release to the environment and the plant is in a safe configuration.
"This issue has been entered in UUSA's corrective action program as EV 159031."
