Title	Violation of Technical Specifications
Event Description	During startup of the reactor with reactor power less than one kilowatt, one of the two required reactor period channels was deenergized. Technical Specification 3.2.3 requires that the reactor shall not be made critical unless there are two such operable channels. For a period of approximately 10 seconds one of the operators inadvertently lifted the wrong cable. The operator identified the error and realized Technical Specifications had been violated. The reactor was shutdown at 1134 EST. An evaluation was performed to identify corrective actions. A labeling issue was identified which contributed to the incident. The licensee notified the NRC RTR Project Manager.
