Sai Praneetha MutyalaEE 444 – Power Systems TechnologyProf Mohammad BeshirSeptember 19th, 2017.EE 444 – Power Systems and TechnologyAssignment 41.The problem that happened with the Fukushima incident was unpredictability of Tsunamiwhich disabled the emergency generators to cool down the reactors. The insufficient coolingled to the three nuclear meltdowns, hydrogen air explosions and the release of radioactivematerial into air. This hence was one of the most dangerous accident and made it get appearon the point 7 on the scale of damage created by it. Due to such events, nuclear power isconsidered as risky. But there are few safety tips which if followed correctly, it can help usfrom preventing such accidents in the future. They are as following:Stabilize the Electric Supply system: As mentioned above, the supply of electric power was cut off from the reactors due toearthquake and Tsunami. And as the emergency generators too failed to perform, themassive explosion occurred. Hence, to prevent such disasters, it is better that multipleconnections to the offsite power grid be installed, and emergency diesel generatorsshould be kept in addition to the number of mobile emergency diesel generators bedeployed. Store spent fuel in dry casks: It is evident from Fukushima accident that when cooling system fails, it is a dangerfor fuel storage pools. As water level dropped, the stored pools also melted away
