Your question is too open- do you mean in a country? If you mean the world then you will have to add all of the different countries amount of electricity together and figure out a percentage then, I wouldn't recommend it though because it will take a lot of research and time.
About 25 percent of all nuclear electricity is generated in the US. France is second with about an eighth. About 20% of all electricity in the US is nuclear. Almost 80% of the electricity in France is nuclear.

19.26 - in 2004
15-25%
Nuclear power accounts for roughly 20% of electricity generation in the United States.
Nuclear Energy provides 13-14% of the world's electricity and 6% of the world's energy in general.
France
A little over 15 percent of total world electricity. See link below.
Nuclear energy typically generates around 10-20% of electricity globally, depending on the country. In some countries, such as France, nuclear energy can contribute up to 70-75% of electricity generation.
About 70-75% of France's electricity is generated from nuclear power plants, making it one of the countries with the highest reliance on nuclear energy in the world.
The US generates most, with 104 power reactors, but France has the largest percentage at around 80 percent of total electricity
Illinois has several nuclear power plants (see link below) with a total generating capacity of 11,263 MWe. I don't have details of other types of power plants in the state.
