Title	Technical Specification Directed Shutdown
Event Description	The following information was provided by the licensee via email: Violation of Limiting Condition of Operation per Nuclear Science Center Reactor (NSCR) technical specifications (TS) 3.5.1. Report made in accordance with TS 6.7.2. At approximately 1300 [CDT], April 25, 2023, it was determined there was a Limiting Condition of Operation that required a remote display for a single Area Radiation Monitor (ARM) on the reactor bridge in the Emergency Support Center. That display had been inoperable for two weeks. The ARM was operable, and the displays in the reactor control room and on the reactor bridge at the ARM location were active. The remote display is located in a different building from the reactor confinement building. Upon discovery of the situation, the reactor was shut down. This notification to the [NRC] Headquarters Operations Officer is required by NSCR TS 6.7.2 within one working day. Corrective actions underway: The display of the ARM is being repaired and will be confirmed to be in operation prior to the restart of the NSCR, and for each successive start up.
