SCENES is a nuclear power plant accident sequence safety analysis software independently developed by the School of Nuclear Science and Engineering at Shanghai Jiao Tong University. SCENES-CoreMt is the core degradation calculation module for severe accidents in nuclear power plants. The high-temperature oxidation phenomenon of core components is of particular significance in the early stages of accidents. A combination of different oxidation model is used to calculate the zirconium-water reaction of the cladding in SCENES-CoreMt. To verify and validate the accuracy and reliability of the cladding oxidation calculation module, this paper uses the QUENCH-06 international standard problem to validate the SCENES-CoreMt cladding oxidation calculation module, and compares the computational capabilities of different combinations of zirconium-water reaction models. The calculation results show that the Cathcart-Pawel model has relatively accurate calculated values in the high-temperature oxidation zone. The hydrogen generation obtained by combining the Cathcart-Pawel and Volchek-Zvonarev model has the smallest error compared to the experimental values, and can relatively accurately calculate the zirconium-water reaction phenomenon.
