Safety of nuclear reactors significantly increased with third generation and forth generation is expected to have even more enhanced safety.

The only real problem regarding nuclear energy is the nuclear waste although as some experts say this problem is less significant than for instance of waste that is produced by coal, or the by the silt that builds up behind dams.
Nuclear power plants' safety especially increased thanks to third generation reactors which have significantly reduced the possibility of a core meltdown accident and soon fourth generation will be also making its entrance, ensuring even higher security levels. Nuclear energy is ecologically even more acceptable than hydropower because hydroelectric dams have negative impact on nearby ecosystems they alter.
Nuclear power is used in many countries of the modern world and France here convincingly leads the way with 77 % of its electricity generated in nuclear power plants. More than 30 countries in the world use nuclear power plants for generating necessary electricity and lots of nuclear power plants is being built, especially in Asia where countries like China and India are under the constant need of new energy sources because of large demands of their sudden economic growth and nuclear energy is one of the best, if not the best solution to satisfy increasing energy needs. Just for example, one pound of uranium produces 20,000 times more energy than one pound of coal which means that nuclear energy is also very competitive energy source despite the fact that nuclear power plants have high initial building costs because operational costs are relatively inexpensive.
