This is 3rd presentation of a series of nuclear system research and development projects "Development of Cr-coated Zircaloy for Accident Tolerant Fuels."
To study the fracture behavior of Cr layer of Cr/Zry double layered material, we performed in-situ measurement during mechanical test using Cr/Zry double layered material. The experimental method and results of the test will be reported in this presentation.
