There were no nuclear power plants during World War II. The Chicago Pile, or CP-1, had a nuclear reaction going for about half an hour, but no energy was derived from it.
The first electrical power generated by nuclear plant was at the EBR-I experimental station near Arco, Idaho, on December 20, 1951, six years after the end of WWII.
On the NRC website, 104 operating reactors
104 nuclear power plants in the U.S.
5 in Pennsylvania
104 operating power reactors
No, nuclear fission operates all nuclear reactors. If they are power plant reactors it is used to generate electricity.
In USA and Russia all plutonium production reactors are now shutdown.
The Hanford site near Richland, WA had the plutonium production reactors and extraction canyons that made and purified plutonium for implosion type bombs.
metal, very similar to aluminum. used for cladding reactor fuel pellets in water reactors.
there was alot of cyclones at the US
Total of 104 reactors, most sites have two reactors
104. See www.nrc.gov
There are 100 nuclear power reactors operating in USA besides five under construction as of July 2014.
104 reactors
104 operating power reactors
I make it 104 on the NRC website (operating units, that is)
All power producing reactors are either PWR or BWR types
There are 59 nuclear reactors in France.
There are 104 commercial nuclear power reactors in the US. See the related question below.
Most nuclear reactors are thermal-neutron reactors. A few fast breeder reactors have been built, but not many.
The US with 100 (I am uncertain if this is all reactors or just power reactors though, there are several small reactors operated to make medical isotopes, etc. or for research purposes of various kinds).
Yes, there are 104 operating reactors in the US
