The problem that happened with the Fukushima incident was unpredictability of Tsunami
which disabled the emergency generators to cool down the reactors. The insufficient cooling
led to the three nuclear meltdowns, hydrogen air explosions and the release of radioactive
material into air. This hence was one of the most dangerous accident and made it get appear
on the point 7 on the scale of damage created by it. Due to such events, nuclear power is
considered as risky. But there are few safety tips which if followed correctly, it can help us
from 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 to
earthquake and Tsunami. And as the emergency generators too failed to perform, the
massive explosion occurred. Hence, to prevent such disasters, it is better that multiple
connections to the offsite power grid be installed, and emergency diesel generators
should be kept in addition to the number of mobile emergency diesel generators be
deployed.
Store spent fuel in dry casks:
It is evident from Fukushima accident that when cooling system fails, it is a danger
for fuel storage pools. As water level dropped, the stored pools also melted away
