HEATRe和MELCOR程序耦合过程中材料物性参数分析

ue to the contradiction appeared among the simulation range, calculation accuracy and operating time, the deficiencies would exist in the utilization of a single code. Retaining the advantage of a single code, the coupling between codes can offset the deficiencies in simulation range through expanding the capability of code. However, the adaptability of material properties often has been emerged from coupling procession between codes because of the properties application strongly depends on its utilizing conditions. The properties of materials like water, steam, air, heat structures and component materials within core degradation are compared and analyzed in order to ensure accurate simulation in coupling between THEATRe and MELCOR codes.
