| Event Description | The following information was provided by the licensee via phone and email:
On June 27, 2024, at 1037 EDT, the North Carolina State University (NCSU) PULSTAR reactor was shutdown due to channel failure of the N-16 detector. This channel is required during operations over 500 kW by TS 3.4a. The reactor was operating at 950 kW at the time of channel failure. The reactor operator promptly shutdown and secured the reactor. Due to the nature of an unscheduled shutdown, investigation as to the source of channel failure and remedy will be commenced. At this time, failure has been isolated to just the N-16 channel. As such, operations may continue with approval for restart by the director of the NCSU PULSTAR reactor at powers below 500 kW. To resume full operations, channel maintenance, required surveillances, and additional approval by the director of the NCSU PULSTAR reactor are required. The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance: The N-16 channel provides a reference power level indication while adjustments are being made to other power level channels. |
