We had two main tragedies in Nuclear power industry; one in Chernobyl and other in Three Mile Island. I am sure, all nuclear experts around the world took these case studies to tighten their safety precautions. Now we have another disaster @ Fukushima Daiichi nuclear power plant, Japan. However, this new accident widen up our angle to see the safety of nuclear power plants. Analysis says failure of cooling systems after automatic shutdown @ 8.9 earthquake was the main cause behind series of blast in Fukushima Daiichi nuclear power plant. As Japan is frequently subjected to earthquakes and tsunamis they might tighten their safety procedures for natural disasters. However the level of the impact of 8.9 earthquake might be very high than what they expected when they design and commissioning Fukushima Daiichi nuclear power plant.
I think we must taken following factors in future discussions of nuclear safety
- 1. Nuclear plants safety at natural disasters
- 2. Shutting down procedures at natural disasters
- 3. Effects on people who already affected by natural disaster (people without communication tools, transportation, … )
- 4. Information management in emergency situation
- 5. Effects on wind patterns at emergency situation
