CX-270274: Effects of High Dose on Laser Welded, Irradiated AIUSI 304SS – Boise State University

Boise State University, in collaboration with Texas A&M University, Purdue University, the Westinghouse Materials Center of Excellence, and Idaho National Laboratory, proposes to assess the mechanical integrity of laser weld repairs of highly irradiated, He-containing AISI 304 stainless steel under extended LWR service conditions. After laser welding, the materials will undergo ion irradiation followed by X-ray diffraction and miniature mechanical tests to measure mechanical properties and residual stress concentrations. Post-ion-irradiation examination will then be performed to provide microstructural corroboration of the observed XRD and miniature mechanical tests.
