Alloys used in nuclear reactors are exposed to demanding conditions that typically deteriorate their structural integrity. In the current fission-based reactors, upcoming Generation-4 reactors, and fusion technology, alloys must withstand harsh thermomechanical conditions, as well as irradiation and chemical attack. Given that nuclear power is key for meeting the world’s energy needs, materials are needed that can reliably and safely operate under these challenging conditions.

This Collection brings together the latest research on alloys used in nuclear reactors. Topics of interest include, but are not limited to, the following:
