Title	Technical Specification Non-Compliance
Event Description	The following is a summary of information received from the University of Utah Reactor Facility via email: At 1217 MDT, on 3/31/2020, during a test of reactor systems, operators discovered that the safety control rod would not drop as expected after magnet power was secured. The safety control rod was manually driven from the 100 percent to 98 percent withdraw position, where it then dropped on its own to the fully inserted position. The reactor was shutdown during safety control rod testing, with the shim and regulating rod fully inserted. As a result, the licensee was not in compliance with Technical Specification 3.2.1.2, which requires the scram time to not exceed two seconds. The reactor will remain shutdown until the rod is inspected and repaired. The licensee notified the NRR Project Manager (Yin).
