Polycrystalline Diamond and Cr Double Coatings Protect Zr Nuclear Fuel Tubes Against Accidental Temperature Corrosion in Water-Cooled Nuclear Reactors

Original language description

The chapter proposes a new strategy for protecting Zr alloy nuclear fuel tubes from accidental temperature corrosion in water-cooled nuclear reactors. Protection of the zirconium alloy fuel tubes against accidental temperature corrosion in water-cooled nuclear reactors is important for the safety and efficiency of nuclear power plants, as corrosion in fuel tubes can lead to accidents and reduce the lifespan of the fuel. The new strategy of zirconium alloy fuel tubes from accidental temperature corrosion presented here involves a combination of polycrystalline diamond (PCD) and chromium (Cr) layers. The PCD layer prevents direct interaction between the Zr alloy surface and the hot water environment of the reactor and releases carbon into the underlying Zr material to alter conditions for the penetration of oxygen and hydrogen. The Cr layer helps to reduce corrosion by forming carbides and improving adhesion of the coatings to the Zr alloy substrate. The chapter also discusses the importance of the order of the Cr and PCD layers and the parameters affecting the corrosion of coated ZIRLO tubes. Overall, this new strategy has the potential to significantly improve nuclear safety.
