There are two, very large negatives to nuclear power.
1. The possibility of a nuclear meltdown. The past fifty years of nuclear power has seen two meltdowns and one close call. These issues could easily destroy hundreds of square miles of land and conceivably kill or inconvenience those that live in these areas. Chernobyl and the current crisis in Japan are examples of absolute worst case possibilities. Three Mile Island is a classic example of a system working to prevent a meltdown.
2. The issue of storing the spent radioactive material is problematic currently. There have been proposals for permanent disposal and even methods proposed to decrease the levels of radioactivity in this material. Politics has prevented these systems from being implemented.
The only current alternative to nuclear power though is coal or fossil fuel plants. The alternative energy proposals can assist in very small terms and in very small amounts. Coal causes hundreds of deaths each year in terms of mining operation issues and black lung. Whether or not these known environmental and health issues are offset by the unknown issues of a meltdown have been debated for decades. The United States has a current policy of taking the known annual deaths from coal as being safer and less problematic than the unknown issues of Nuclear.
Well their are no disadvantages to nuclear plants, if your using them for nuclear power, as nuclear power is the safest type of energy in modern times. However disadvantages of nuclear weapons include well the ending of the planet, the possibility of it being stolen by terrorists or even it being spied on for another nation so it can create nuclear weapons.
I imagine they are similar to the disadvantages inherent in nuclear power, mainly the waste products, but this is clearly not stopping development. See the link below on the Chinese nuclear industry
it can be very dangerous if not careful
THE disadvantage of using high power objective is to
32 countries in the world are using nuclear electric power.
Nuclear power plants
Nuclear power is neither good nor bad. The way nuclear power is produced (Safety) can be good or bad, though. Nuclear power can be generated by small power plants, creates no air pollution, and is safe when done right.
Using nuclear fission, generators are turned.
France is the country that is committed to using nuclear power to generate electricity and has the majority of its electricity needs provided by nuclear power. Nuclear power accounts for around 70% of the electricity generated in France.

This is a disadvantage of nuclear power. But there are even more disadvantages for coal or natural gas power generation. The technology will come to figure out what to do the waste.
Advantages of uranium as a fuel include high energy density, which means it can produce a large amount of energy from a small amount of material. It is also a reliable and proven technology for generating electricity. However, disadvantages include the risk of nuclear accidents, the generation of radioactive waste, and the potential for nuclear proliferation.
