In the middle of the Fukushima disaster, I thought it was important to educate a bit fellow students about the ins and outs of nuclear power, to oppose the mainstream media alternating terror and ridiculous assertions.

Usage of the reaction •Military •chain reaction •as much energy as possible on the shortest time •boom. •Civilian •controlled reaction •generate electricity •…boil water
Renewables • 1 GW: one standard nuclear reactor • several reactors in a plant • ~ 6000 wind turbines • ~ 10 km2 of solar panels • lots of research in renewables
A long-term problem… • “Short life” waste needs a few years to deteriorate • tools, scrap, rubbles… • “Long life” waste needs several million years! • reactor's core elements
A long-term problem… • “Short life” waste needs a few years to deteriorate • tools, scrap, rubbles… • “Long life” waste needs several million years! • reactor's core elements • most dangerous: used fuel

Conclusion: nuclear power • electricity production • very efficient • a solution against climate change • new long-term, large-sized pollution risks • changed humankind vision
Conclusion: nuclear power • electricity production • very efficient • a solution against climate change • new long-term, large-sized pollution risks • changed humankind vision • we are able to destroy the whole world • several times
