Description
Integral tests with bundles of Zircaloy₋4 fuel cladding coated with 10 μm Cr, 20 μm Cr, and 26 μm Cr/CrN were carried out under simulating design extension conditions (DEC) using an induction heating furnace at the CRIEPI's DEGREE facility. The bundles were heated to 1350 °C or 1500 °C in a steam-Ar mixed gas atmosphere and then quenched in Ar gas. In addition to on-line measurements of cladding surface temperatures and fuel rod internal pressure (RIP), post-test analyses were performed to understand the ballooning/burst behaviour and the degradation behaviour of the coating layer itself and those at the coating/substrate interface.
