It has been a hot issue in Japan since March 2011 whether we need nuclear plants. As for myself, I am against building of nuclear power plants.
Some people who agree to building of nuclear plants believe that electricity fees would definitely rise without nuclear plants. They think that an abolition of nuclear plants would cause a negative effect for the manufacturing industry in Japan. Surely a nuclear plant can produce electric power cheaply but the construction cost of a nuclear plant is very expensive. Moreover, a disposal of radioactive wastes would involve much higher costs than easily imagined. Nuclear power is not so economical as they claim, if you add to the total cost the construction cost as well as the cost of abolishing the nuclear plants in the future. In addition to the cost factors, the radiation of nuclear plants is hazardous to human health. If big natural disasters such as tsunami should take place nearby a nuclear plant, a wide range of the region may be exposed to contamination of radioactivity. Naturally, residents in the neighborhood cannot avoid serious health damages.
Thus, nuclear plants have very much unforeseen risks for the future generation. All things above considered, we should have much wider views of nuclear power issues than ever before.
