NSUF 19-CINR-16547: NuScale SMR Materials Irradiation and Testing
NuScale Power, LLC (NuScale) is evaluating first-of-a-kind use of higher strength vessel steels for the NuScale Power Module™ that have the potential to dramatically reduce manufacturing cost and production timelines.The objective of the NuScale SMR Materials Irradiation and Testing program is evaluation of materials for use in the NuScale lower containment vessel. Specifically, our objective is to obtain low temperature irradiation embrittlement data for base metal, weld metal, and heat-affected zone (HAZ) material from SA-508 Grade 3 Class 2 weldments and Code Case N-774 Grade F6NM weldments. Irradiation of materials will be followed by tension and Charpy testing to determine the ductile to brittle transition temperature shift for these materials.
