The first nuclear reactor, CP-1, was built and operated in 1942. It generated no electricity, its peak thermal power was one half watt.
The first nuclear power plant was connected to the grid sometime in the 1950s.

Where does the energy of a nuclear reactor come from?
Heat is released during nuclear fission of the fuel, which then heats water, turning it into steam, which drives a turbine as it rises, which then turns a generator, creating electricity.
Artificial satellite has many electric devices in themFrom where does the energy come from?
Either nuclear energy from some on-board reactor, thermopile or solar Cells
Did radiation from Japanese nuclear reactor hit Tokyo after tsunami?
At some level, yes it did. It has managed to hit a very large area and will for years to come.
How many type of nuclear energy?
Nuclear fission reactors come in various forms, though the principle of using the heat from a nuclear chain reaction is always the same. 1. Pressurised Water Reactor (PWR). 2. Boiling Water Reactor (BWR). 3. Magnox gas cooled reactor (no longer built) 4. Advanced gas cooled reactor (no longer built but still in use in UK). 5. Canadian heavy water reactor (Candu) 6. Russian design of Chernobyl type. I think this covers the most used types for power generation. There are others such as the gas cooled pebble bed reactor, and the fast breeder reactor, that are possible but designs have not been so successful and these have not been adopted commercially.
When was the last nuclear power plant ordered in the US?
According to the US Dept of Energy, the last reactor built was the "River Bend" plant in Louisiana. Its construction began in March of 1977. The last plant to begin commercial operation is the "Watts Bar" plant in Tennessee, which came online in 1996. Note: The list I obtained only listed operational reactors.
Where does uranium and plutonium come from?
Uranium is a natural element extracted from ores. Plutonium is an artificial element obtained in a nuclear reactor by nuclear reactions from uranium 238.
What is the Environmental hazards of a nuclear reactor?
The nuclear Reactor is safe unless a Radioactive Leak happens. The chances of a Radioactive Leak Happening is quite low. The main concern is that when nuclear power plants use the lakes or rivers to gain coolants is that it can kill the fishes due to thermal pollution (waste heat) in the particular area. The other Concern is the Waste. The nuclear waste emits around 148 Roentgens Per hour and has to be buried at locations that will be Uninhabitable for thousands of years to come.
Why do nuclear reactors need sheilding?
so that the harmful radiations do not come out of the reactor and harm the living organisms including human beings. because many of the radiations can cause severe damage
Does the energy for evaporation come from the sun?
99.9% of Earth's energy comes from the Sun. It is usual, especially in the natural water cycle for the energy to evaporate water to come from the Sun. Of course you could also use the heat from a nuclear reactor.
How much radiation does a nuclear reactor produce?
As far as I know, reactors come in different sizes, producing different amounts of power, so you would expect the amount radiation to vary, as well.
How would you summarize why a nuclear power plant cannot explode like a nuclear bomb?
A nuclear bomb works by suddenly getting a supercritical mass of U235 or Pu239 together by some sort of explosive device (I am no expert on bombs). Although a nuclear reactor contains enough fissile material to produce a bomb, it can never come together like that. For one thing even the new fuel only contains around 4 percent U235, the rest is U238, and you could never make a bomb from such material no matter how you tried, it is too dilute. Also in a reactor the fuel is spread out in discrete pieces separated by the moderator. If a reactor ran away because the control rods motored out without the reactor protection working, which is made pretty well impossible by the design of the systems, the fuel would just overheat and eventually melt so that the reactor configuration of the fuel/moderator lattice was destroyed, and the neutron chain reaction would cease. The Chernobyl disaster, where the top of the reactor was blasted open, happened because of a steam pressure surge, not a nuclear reaction like a nuclear bomb.
Where does the energy of a nuclea reacter come from?
The way a nuclear reactor works is that a atom or multiple atoms are either smashed into each other creating a sudden energy explosion, this is known as nuclear fusion. Or individual atoms are split and produces around about the same amount of energy.
