Experimental Study, The Leakage Of Sodium Receive Inhibit The Plate On The Inhibition Of Sodium Fire Accident

This paper represents the design and the experiments of a facility of the passive sodium fire extinguishing system 梩he sodium fire suppressing pan of receiving leak sodium, and described the construction of the trial control system and the data collecting system. In the process of the experiment, the original design of the pan has improved. By comparing the sodium combustion phenomenon of the sodium fire suppressing pan with that of sodium receiving pan without suppress, the suppressive results of the pan are very obvious. At the sodium temperatures of 250 癈 ~ 410 "C , the receiving efficiency of the pan can attain 93.11%, the sodium overflow efficiency of the pan can attain 100%. The research results can be used for the passive sodium fire extinguishing system of primary and second sodium loops of CEFR.
