Classification: CPC G  Y | IPC G

Claim 8:
9. The dynamic characteristic analysis method according to claim 8, wherein as there is no state transition of DET simulation object in the DET branch, the method for updating the restart file for the RELAP5 comprises:
S511: updating a restart number at a first bit of a 103 card in the restart file for the RELAP5 of current node to be a last restart number ResNumLast in a simulation result file *.o of current simulation step; and
S512: updating a simulation end time SimTime at a first bit of a 201 time control card in the restart file for the RELAP5 of the current node according to a following formula:

SimTime=SimTime+ΔT 

where SimTime represents a simulation time of the time control card in input cards of the RELAP5, namely, a simulation time at the end of the current node; and ΔT represents each the simulation step of the RELAP5.
