Investigation on Hydrogen Inerting Mechanism of Enviromental-friendly Freon Under Severe Accident in Nuclear Power Plant

ZHANG Sheng-jun;SHEN Feng;State Nuclear Power Research Institute;  
In dealing with the hydrogen risk management under severe accident,the study of the minimum inerting concentration(MIC)on hydrogen of different gases was carried out.And the mechanism difference between conventional inert gas and freon was elaborated.The inhibition factor of inert gas was calculated by the group contribution method.The MIC was predicted with flame propagation speed and stoichiometric concentration.The results show that the MICs of HFC-134 a,HFC-245 fa and HFC-125are15.87%,14.12% and 10.39%,respectively.HFC-125 shows the best inerting performance.The minimum inhibition concentrations of the three freon are 34.9%,32.7%and 25.9%,which are much lower than N2 and CO2with 94.5%and 90.9%.
