Abstract

The current development of accident-tolerant fuel (ATF) claddings is aiming at the improvement of the high temperature integrity of new solutions over the existing zirconium claddings. The characterization of the new proposed cladding materials is essential in order to assess their feasibility in commercial use. The cladding material should tolerate loss of active cooling for a significant period of time without failing. This paper describes the experimental work done at VTT on a candidate cladding solution by using a high temperature steam furnace capable of working at temperatures up to 1600°C. Experiments were performed on CrN coated AISI316L coupon and NiCrAlY coated 800H tube specimens at the temperatures of 1100°C, 1200°C and 1300°C in flowing steam conditions. Post-test analyses are reported in terms of weight change measurements and microstructure observations by using state of the art electron microscopes.
