Method for determining actual position of control rod adjusted by electrical control rod derive along operating displacement in nuclear reactor, involves arranging inductive sensor system with multiple coil pairs

摘要

The method involves arranging an inductive sensor system (22) with multiple coil pairs (C-1 to C-12) over an operating displacement with a primary coil. The primary coil is loaded with an alternating voltage. An inductive secondary coil is coupled with the primary coil. The two determined position characteristic values and a third position characteristic value are displayed on a display unit (28). The third position characteristic value is derived from two position characteristic values. An independent claim is included for a device for determining an actual position of a control rod adjusted by an electrical control rod derive along an operating displacement in a nuclear reactor.
