Nuclear power plant cannot disuse in Japan now a days. There are three reasons . First we cannot save electricity as much as made by nuclear power plant. We always use much electricity every time, it caused we have to dependence nuclear power that can make a lot of energy , so it cannot change easily. Second we have to study about alternative energy like hydroelectric and so on. We already have many way to make energy without nuclear power , but it is not perfect now. It is enough not to make sufficient electricity. Finally, we cannot change power company structure. Only few company monopolize right to treat electricity in Japan. If they  try to share their own electricity with others, we don't lack it while summer without nuclear power plant. However, it is really difficult thing now. For these three reasons, we have to depende on nuclear power for some time.
