Simulation Experimental Research on Passive Residual Heat Removal Performance for Nuclear Seawater Desalination Reactor

Simulation experiments were conducted on the integral simulation test facility with scaling ratio 1/45 for nuclear seawater desalination reactor, the performance of the passive residual heat removal from the core was presented in the paper. The experimental results demonstrated that residual heat can be removed from the core effectively after the reactor was shut off in emergency because some accidents take place, such as station blackout accidents. The paper also presented the RELAP5/MOD3.2 code simulation results for the experimental conditions, and the calculation results of the code is well accordance with the experimental results.
