Polycrystalline diamond coating protects Zr cladding surface against corrosion in water-cooled nuclear reactors: Nuclear fuel durability enhancement

Original language description

In this chapter we demonstrate a new strategy for the protection of zirconium (Zr) nuclear fuel cladding material by composite polycrystalline diamond (PCD) layers against corrosion in water-cooled nuclear reactors. We show that Zr alloy surfaces can be effectively protected against oxygen and hydrogen uptake at both accident and working temperatures in water-cooled nuclear reactor environments by coating the Zr surface with PCD layers grown in a microwave plasma chemical vapour deposition apparatus. This composition enables PCD layers to have suitable thermal expansion over a wide range of temperatures leading to no delamination. A key requirement is effective protection of Zr alloy surfaces against oxidation and hydration under standard operating conditions (360 °C). Oxidation of PCD-coated Zr alloysurfaces after more than 100 days in 360 °C hot water was significantly decreased (35-55%) compared with that of unprotected Zr alloy processed under the same conditions.n
