Abstract

Abstract

As a common mechanistic code for safety analysis of severe accident,SCDAP/RELAP5 can simulate many types of core components phenomenon during severe accidents.Comparison of simulation model of fuel behavior under severe accident between fuel rod and ATR plate is described in this paper and the approach for simulating severe accident of UO₂-Zr plate is concluded by combining structure properties of UO₂-Zr.It is concluded that the basic analysis of severe accident of UO₂-Zr plate could be achieved by S/R code from the code simulation.However,new core structure,new model of fuel behavior and combination of existing model should be developed in S/R code to simulate the precise core behavior of reactor assembled with UO₂-Zr plate under severe accidents.
