Hydrothermal corrosion behavior of CrN/Cr2N‐ZrN ceramic as a surrogate nuclear fuel
Abstrak
In this study, the hydrothermal corrosion behavior of zirconium nitride (ZrN) ceramics used as a surrogate nuclear fuel of UN, which were added with different amounts of CrN/Cr2N (0, 10, 20, and 30 vol.%), was investigated with the objective of increasing the loss‐of‐coolant accident (LOCA) tolerance of pressurized water reactor fuel. The ZrN‐based ceramic samples with a density exceeding 98% were fabricated by using a spark plasma sintering system at 1700°C and applied stress of 30 MPa. Following 30 min of hydrothermal corrosion at 300°C, the oxidation layer thickness of pure ZrN ceramics was 9.11 ± 1.96 µm, whereas that of 30 vol.% CrN/Cr2N‐ZrN was only 1.23 ± 0.3 µm, which indicated that CrN/Cr2N offered an excellent protection effect for ZrN. This work can, thus, provide engineering design guidance for the UN with high uranium density to increase the LOCA tolerance of current nuclear power generation systems.
