Abstract
Disclosed is a diagnostic apparatus structured to be electrically connected with a coil stack of a drive mechanism of a control device of a nuclear reactor. The coil stack has a plurality of coils. The diagnostic apparatus includes a power supply and a controller including a processor and a memory that stores a number of routines including a number of instructions. When executed on the processor the instructions cause the diagnostic apparatus to apply to a coil a voltage that varies as a function of time, detect a current in the coil as a function of time, identify in the current a first inflection point and a second inflection point, and determine, based upon an electronic evaluation that includes the first inflection point and the second inflection point, that the coil is one of functioning properly and in a state of at least partial failure.
