1. The number one problem of nuclear power is the radioactive waste. The waste from nuclear energy is extremely dangerous and it has to be carefully looked after for several thousand years. There are not really any solutions to this problem, except for nuclear waste treatment.2. It is a high risk power supply. Of course a nuclear power plant has a very high security standard, but it is impossible to build a plant with a 100% security. Horrible consequences will be there if an error or accident occurs in this plant.3. The time frame needed for formalities, planning and building of a new nuclear power generation plant is in the range of 20 to 30 years in the western democracies. In other words: It is an illusion to build new nuclear power plants in a short time.
