ATF concepts aim to improve reactor safety margins by reducing hydrogen generation and extending coping time under off-normal and accident conditions. FeCrAl alloys are particularly promising due to their superior oxidation resistance in high-temperature steam environments, compared to conventional Zr-based claddings. To evaluate the capability of MELCOR V2.2 to model innovative cladding materials, this study compares simulation results against the QUENCH-19 bundle test, conducted at KIT’s QUENCH large-scale facility in 2018, focusing on thermal response and hydrogen generation under representative severe accident conditions.

Abstract
ATF concepts aim to improve reactor safety margins by reducing hydrogen generation and extending coping time under off-normal and accident conditions. FeCrAl alloys are particularly promising due to their superior oxidation resistance in high-temperature steam environments, compared to conventional Zr-based claddings. To evaluate the capability of MELCOR V2.2 to model innovative cladding materials, this study compares simulation results against the QUENCH-19 bundle test, conducted at KIT’s QUENCH large-scale facility in 2018, focusing on thermal response and hydrogen generation under representative severe accident conditions.File in questo prodotto:
