(20)Oxidation model improvement in SAMPSON considering steam conservation and cladding rupture
キーワード:Fukushima accident, Oxidation reaction, Creep rupture
Oxidation reaction of these metals with high-temperature steam would have significant impacts on the melting and subsequent core relocation. During the core heat-up, the small leakage flow of steam caused by failure of the reactor coolant system pressure boundary determines the availability and the distribution of steam in the core, which could limit the total amount of oxidation energy.
