Abstract: The system model of Subcritical Energy Reactor（SER） was primarily established,which was based on SER conceptual design and by taking PWR loop model as references.With RELAP5/MOD3.3 code,initial steady state and transient conditions including power increase accident,loss of coolant flow accident and loss of heat sink accident were analyzed.The results show the limit value during the accidents and make the safety characteristics of SER clear.Suggestions have been offered for SER safety.The work could give references for the following conceptual design and engineering design in hybrid energy reactors.
