  1. Fukushima Nuclear Safety: Myths and Realities

  2. How does a NuclearPower Plant work?

  3. Earthquake &Tsunami Fukushima 1

  4. Nuclear reactors1, 2,3automatically stopped • Nuclear reactors4, 5,6were under maintenance • The fuel elements remained with their residual heat(<5%) Fukushima

  5. The emergency cooling systems operated in accordance with protocols • Failing main power supply due to earthquake, secondary systems worked normally powered by emergency diesel generators & batteries. • Between the earthquake and the impact of the tsunami, the safety protocols worked as intended by design. Fukushima

  6. Due to the tsunami, water flooded and left inoperative diesel generators, batteries and control systems of the nuclear power plant. • All actions were aimed to prevent overheating of the fuel elements in their pressure vessels and secondary pools. Fukushima
