Description
A modified friction stir lap welding process was developed to encase uranium alloy foil in an aluminium jacket and results were compared with two other bonding methods for fabricating monolithic fuel plates, namely hot isostatic pressing and transient liquid phase bonding with silicon powder at the interface. Requirements for a bonding process to commercially fabricate monolithic nuclear fuel are listed. Adaptation of friction stir welding for fuel element applications was considered and optimum process parameters (tool pin diameter, shoulder diameter, rotation speed and transverse speed) were evaluated. Warping constraint and roughness removal issues were assessed also. Bond quality for all three joining processes was examined by bend testing, ultrasonic testing and microscopic observations. Irradiation testing criteria are outlined.
