There are 436 nuclear power plants in the world
There are 441 nuclear power plants in the world. Please see the Related Link below for more information.

There are about 430 nuclear power plants worldwide, depending on how you count them. This number does not include the plants used to power ships, of which there are something over 150. Nor does it include research reactors that do not provide electrical power to a power grid. Also not included are small nuclear power plants, such as are used in hospitals for the production of radionuclides for medical use.

The entry says it may not be complete, but there isn't much missing. This list does not include research or prototype plants, and it does say 'major' power plants so there may be a few small ones missing. Also plants which are in decommissioning are not included, so historically there are some which have operated in the past but are now permanently shutdown.
Presumably you mean nuclear power plants, not nuclear weapons. Most people would I think say nuclear power is more dangerous, but just look at the figures. The worst accident ever was at Chernobyl and I think about 50 people lost their lives directly, though more may get cancer eventually. Many people get cancer without nuclear power of course. But just think about how many coal miners have been killed in mining accidents, and how many have been killed in accidents on oil rigs, especially off-shore ones. This will put it in perspective. In a normal year, no-one is killed in nuclear plants due to nuclear accidents, though there are bound to be some normal type industrial accidents, and in fact as far as I know there has never been a death in a US nuclear plant due to a nuclear cause.
Nuclear power plants typically contain a reactor core where nuclear fission reactions occur, a coolant loop to transfer heat away from the reactor, control rods to regulate the fission process, a steam generator to produce steam for electricity generation, and a containment structure to prevent the release of radioactive materials.
Nuclear fuels, such as enriched uranium, are produced in specialized facilities known as uranium enrichment plants. These facilities use various methods to increase the concentration of uranium-235, the fissile isotope used in nuclear reactors, in raw uranium ore. Once enriched, the uranium can be fabricated into fuel rods for use in nuclear power plants.
It depends what type of power plant. A coal-burning power plant will produce CO2 and SO2, which are both pollutants. Nuclear power plants and geothermal power plants produce steam, which is not a pollutant. There are many other types of power plants, but most produce CO2 and SO2 or steam.
Neither fossil fuels nor nuclear energy can be considered completely clean energy like hydroelectric. The recent nuclear accident in Japan shows that accidents from nuclear power plants can be devastating. The environmental impact of fossil fuels results when we use them in our cars and power plants. The primary pollutant is carbon dioxide, which is responsible for global warming and acid rain. Some question the conclusions of global warming as related to carbon dioxide but it is a fact that burning fossil fuels causes pollution. The principal problem with nuclear energy, under normal operations, is the safe disposal of the spent fuel. As more nuclear power plants are built, this becomes a very large and complex problem, as the spent fuel stays radioactive for many years. Transporting it to a safe location, and insuring that it will never leak radioactivity is difficult. I have attached links on the environmental problems with nuclear energy. A nuclear power plant that is not operating properly with the cooling of the core, runs the risk of radiation leaks, and ultimately if not controlled, a melt-down. You may find extensive discussion on the nuclear power plant accidents in the links I have provided. There is little environmental impact of nuclear power under normal operations of generating electricity. There are occasional releases of low level radioactivity, and the impact of this radiation in the surrounding areas is generally considered minor. The cooling water does become radioactive, but is contained in a closed loop so it is not under normal operating conditions released to the atmosphere. I have tried to find links in the internet that are not biased and present the facts about nuclear energy and fossil fuels. See related links.
There are currently 435 nuclear power plants operating allover the world, per the statistics of the International Atomic Energy Agency as of 1 st of April 2004.

Nuclear energy is harnessed in nuclear power plants, where nuclear reactions generate heat to produce electricity. This form of energy is used to generate about 10% of the world's electricity, with countries such as the United States, France, and China having significant nuclear energy capacity.

The word "nuke" can mean a nuclear power plant or a nuclear weapon.As of January 2013, there are 437 nuclear power plants in operation in the world.Because countries with nuclear weapons are secretive about how many they have, the exact number of nuclear weapons is not known. The Federation of American Scientists estimates there are more than 17,000 nuclear warheads in the world as of 2012.
The reason is that there are many people around the world who are uneducated in the nuclear power field and therefore still assume the stereotypical nuclear meltdown or mutations will occur and as such, oppose their construction vehemently. Also, it is quite expensive to develop and build such plants.
There were 104 commercial nuclear power plants operating in the United States as of 2009.
