Abstract
A method of repairing a slip joint on a jet pump assembly between an inlet mixer and a diffuser, with the diffuser having an opening that receives the inlet mixer with a given spacing between an outside diameter of the inlet mixer and an inside diameter of the opening in the diffuser forming an annulus whose spacing is a product of manufacture and vibration wear. The method comprises the steps of remotely accessing the annulus and narrowing a radial dimension of the annulus.
