Japan has started to produce electricity from nuclear power after closing down all its nuclear power plants in the wake of the Fukushima nuclear disaster. A plant with billions of dollars of safety equipment has restarted and the Japanese Government and plant operators have promised that another Fukushima will never happen again, because of all the new safety measures. Another 25 nuclear power stations have applied for permission to get back into operation.
Since Fukushima Japan has produced electricity from imported liquid petroleum gas and although the nuclear industry formerly produced 30% of Japanese electricity requirements the Japanese have managed to make electricity efficiency savings of 15%. It usually takes a disaster to force people to do things properly.
I hope that Japan will experience nuclear safety but I do not see how anyone can guarantee the safety of a nuclear power station. Apart from the likelihood of human error, Japan is subject to severe earthquakes and there is always the possibility of another tsunami, and however strong and well man may make something nature is far stronger and can destroy it quite easily.
The starting of the nuclear power plant has happened just days after the 70th anniversary commemorations in Japan of the dropping of a nuclear bomb on Nagasaki.
