1. A method of moving a control element in a nuclear reactor, the method comprising:
energizing a first induction coil outside of an isolation barrier in a control rod drive, wherein the energizing drives a magnetic material secured to the control element inside of the isolation barrier such that the control element linearly moves, wherein the energizing does not move the induction coil, wherein the induction coil is in a vacuum environment, and wherein the control element is in a pressurized reactor environment.
