    Abstract: A sealing member is provided to create a sealed region about an annulus formed between an inner body, such as a thermal sleeve, and an outer body, such as a control rod drive housing nozzle. Liquid is introduced into the sealed region to create a flooded region, which is pressurized to a desired level. A nozzle is provided into the flooded region, the nozzle being configured to fit within the annulus. Pressurized fluid is ejected from the nozzle, causing the formation of cavitation bubbles. The nozzle flow causes the cavitation bubbles to settle on the surfaces forming the annulus. The collapsing impact of the cavitation bubbles imparts compressive stress in the materials of the surfaces forming the annulus.

    Abstract: Systems and methods for generating beneficial residual stresses in a target material by generating cavitation shock waves through the use of a cavitation intensification conditioner. Shock waves emanate through the target material from collapsing cavitation voids in a liquid jet to generate residual stresses without significantly deforming the surface of the target material. A high pressure liquid is accelerated through a submerged peening nozzle to generate a high-speed liquid cavitating jet that is further intensified and controlled by use of the cavitation intensification conditioner.
