The direct vessel injection (DVI) line loss of coolant accident (LOCA) experiment is simulated by CATHARE code in this paper. The main processes and physical phenomena under DVI LOCA, such as system depressurization, passive injection and the cooling of core, are well simulated. The calculation results of primary system pressure, Core Makeup Tank (CMT) injection flowrate, Accumulator (ACC) injection flowrate, In-containment Refuelling Water Storage Tank (IRWST) injection flowrate and core fluid temperature agree well with the experimental data. It shows that the CATHARE code can be used to analyze the transient behaviors of passive injection system under LOCA.
