Longer operational life and improved resistance against severe accidents for advanced water-cooled reactors are achievable by coating traditional structural materials, to reduce corrosion rates, improve high temperature oxidation resistance and minimize hydrogen uptake. In the framework of European project IL TROVATORE, ceramic oxides are proposed as protective coatings for Accident Tolerant Fuel (ATF) cladding in the Pressurized Water Reactor (PWR). Materials matching neutronic requirements and chemical stability in PWR environment are produced as sintered pellets, and as thin films by the Pulsed Laser Deposition (PLD) technique. After exposure to pure water at 360°C and saturation pressure, simulating PWR core during normal operation, detected mass changes are correlated to superficial and structural modifications. Best candidate oxide, grown on relevant substrates (Zirconium-based alloys and AISI316L) by optimized PLD process, proves effective protection and significant reduction of substrate oxidation, hence promoting PLD as viable technique to produce high-performance, strongly adherent ceramic films.
