Abstract
A BWR jet pump assembly has a wedge slidably mounted on a jet pump that is movable under the force of gravity to seat between a bracket and the jet pump in order to horizontally support the jet pump against vibrations. The wedge or the bracket is repaired in situ by: providing a spacer layer between mating surfaces of the wedge and the bracket; and then lowering the wedge until the spacer layer is between and in contact with the wedge and the bracket.
