On March 11, 2011, a natural disaster created by earthquakes and Tsunami caused a serious potential of nuclear reactor meltdown in Fukushima due to the failure of emergency core cooling system using diesel generators. In this paper, heat pipe based emergency core cooling system has been proposed for nuclear power plants. The proposed heat pipe system will operate in fully passive mode with high runtime reliability and therefore provide safer operation of nuclear power plants. Based on the simulation model, it was estimated that, using proposed heat pipe system, the reactor water temperature can be reduced to below 100 ℃ in less than 12 hours.
