Abstract
A tool for uncoupling and coupling an extension shaft assembly from a control element assembly of a nuclear reactor during reactor servicing is disclosed. The extension shaft assembly is transitionable between a coupled configuration where the extension shaft assembly is coupled to the control element assembly and an uncoupled configuration where the extension shaft assembly is uncoupled from the control element assembly. The tool comprises a support structure selectively attachable to the extension shaft assembly, a linear actuator, a microcontroller, a power source connector, a plunger shaft selectively attachable to the extension shaft assembly, and a sensor coupled to the microcontroller and the linear actuator. The sensor monitors a parameter indicative of a force experienced by the extension shaft assembly during at least one of a first actuation stroke or a second actuation stroke of a linear drive of the linear actuator.
