[2I10] Severe accident analysis for core fuel with SiC cladding
(1)Evaluation by severe accident analysis code MAAP
Keywords:SiC cladding, SiC channel box, SiC-water oxidation reaction, Amount of hydrogen generation
A new water-SiC oxidation reaction model was incorporated to MAAP, and applied to Zry claddings, Zry channel boxes, and SUS structures in core. As a result, in the case of applying to the new model to the above three parts, an less amount of hydrogen was generated than the traditional model.
