-Nuclear energy has a very high cost, even with large government subsidies. Along with this, the maintenance fee is very large. Also, a significant amount of money has to be spent on security.
-When major accidents occur such as Chernobyl and Three Mile Island, there is a significant environmental effect. Consequences of an accident/ meltdown could be disastrous.
-There is no acceptable solution for long term storage of radioactive wastes, and decommissioning warn out plants. Nuclear waste produced is dangerous for thousands of years.
-There is a high cost of decommissioning plants.
-There is a risk of nuclear proliferation associated with some designs. Nuclear power plants are also spreading knowledge and technology for building nuclear weapons.
-There is a danger of radiation, and potential terrorism.

Nuclear power is not the best way to produce energy. To begin, it is dangerous. There is risk of a catastrophic accident happening such as Chernobyl and Three Mile Island. On April 25th -26th, 1986 the World's worst nuclear power accident occurred at Chernobyl in the former USSR. This accident occurred when the chain reaction in the reactor became out of control creating explosions and a fireball which blew off the reactor's heavy steel and concrete lid. The Chernobyl accident killed more than 30 people immediately, and as a result of the high radiation levels in the surrounding 20-mile radius, 135,000 people had to be evacuated. Three Mile Island Accident occurred in Pennsylvania. This partial meltdown was caused by equipment malfunctions, design related problems, and worker errors, and caused a release of radio activity. Nuclear plants are also dangerous because they spread knowledge and technology for building nuclear weapons. Also, there is no acceptable solution for long term storage of radioactive waste (which is dangerous for thousands of years). The final reason why nuclear plants are dangerous is because of the danger of radiation and potential terrorism. Nuclear power is also very expensive even with large government subsidies. A significant amount of money is spent on safety, as well as maintenance and decommissioning plants. Finally, nuclear fuels are nonrenewable energy sources, with limited high concentration ore reserves. There is a large amount of trace concentration nuclear material in sea water and in most rocks; however extraction from these is not economical.
