Abstract
A magnetostrictive wire control rod position indicator for determining a real-time position of a control rod using a mutual interference effect between a magnetic field formed by supplying a pulse current to a magnetostrictive wire provided inside a protecting tube and a magnetic field formed by a permanent magnet of a drive shaft includes magnet members installed at an upper limit position and a lower limit position of the magnetostrictive wire control rod position indicator to cause magnetic field interference with the permanent magnet of the drive shaft.
