The homogeneous flow model of trans critical transient calculation is achieved by the trans critical program of SCWR which is made by FORTRAN. The SCWR sliding pressure starting scheme is simulated by this program. So that the pressure raising stage characteristic of its booting process is analyzed. The calculation result shows that, in the pressure raising stage of booting process, the maximum cladding temperature gradually increases. Coolant temperature increases gradually along with the flow direction. The dry degree also increases along with the flow direction. The highest temperature of cladding does not exceed 650 °C limits. There is no major adverse effect on heat transfer of fuel rod in the dramatic changes in the physical properties of water.
