ABSTRACT The invention provides an electromagnetic technique for repositioning garter springs, located between the coolant tubes and colander tubes of fluid cooled nuclear reactors in which the garter springs are not directly accessible by mechanical means. An electromagnetic coil is advanced along the selected fuel channel to a position adjacent the garter spring, and a current pulse is passed through the coil thereby to exert an electromagnetic repulsive force on the garter spring having a component in the direction of the required displacement.
