All power producing reactors are either PWR or BWR types
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).
Nuclear reactors in the US are located in various states across the country. Some states with a high concentration of nuclear reactors include Illinois, Pennsylvania, and South Carolina. These reactors are typically situated near bodies of water for cooling purposes.
There are 100 nuclear power reactors operating in USA besides five under construction as of July 2014.
There are 104 operating nuclear reactors in the US. See www.nrc.gov for maps and lists
Nuclear reactors use nuclear fission.
Total of 104 reactors, most sites have two reactors
As of October 2023, there are 93 nuclear power reactors operating in the United States. These reactors are spread across 28 states, contributing approximately 20% of the country's electricity generation. The U.S. has the largest number of operational nuclear reactors in the world.
104. See www.nrc.gov
In 2007, US nuclear power plants generated 806.5 billion KWh. This was 19.4 percent of total US electricity. 69 PWR and 35 BWR reactors contributed to this total. Source: Nuclear Energy Institute, www.nei.org
Nuclear reactors use controlled nuclear fission reactions to generate heat, which is then used to produce steam that drives turbines to generate electricity. The heat is produced in the reactor core where nuclear fuel rods containing uranium or plutonium undergo fission reactions. The reactor's cooling system helps regulate the temperature and prevent overheating.
There are 104 commercial nuclear power reactors in the US. See the related question below.
