| ENS 54222 | 14 August 2019 23:00:00 | Non | Failure to Meet Technical Specification Requirement | The following synopsis was received from Rensselaer Polytechnic Institute (RPI) via phone: On August 14, 2019, at 1900 EDT, during a reactor startup and the reactor critical, the RPI reactor was scrammed due to one of the three safety system channels required by Technical Specification (TS) 3.2.6 not responding to an increase in power. Upon investigation the licensee realized that a test cable was still connected to the input of that instrument channel and the instrument was not connected to the neutron detector. The highest power level reached was 0.14 W. The licensee contacted the NRC as required by RPI TS 6.7.2. In addition, during the scram, one of the four control rods was stuck 2 inches off the bottom. Upon investigation the licensee realized that foreign material (screw) was jammed at the end of the rod. The licensee removed the screw and the control rod was fully inserted. The licensee plans to perform a rod drop test prior to resuming normal operations. There was no additional dose to the facility staff. The NRC inspector was on sight when the event occurred. |
