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.
All power producing reactors are either PWR or BWR types
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.

Spent fuel rods from US nuclear reactors are typically stored on-site in specially designed pools or dry cask storage systems. The long-term storage solution, however, is to transfer the fuel rods to a geological repository, such as the proposed Yucca Mountain repository in Nevada.
Purpose: Nuclear reactors are designed to produce electricity through controlled nuclear fission, while nuclear bombs are designed to release a large amount of energy in an uncontrolled nuclear fission chain reaction. Control: Nuclear reactors have various safety features and control mechanisms to regulate the nuclear fission process, while nuclear bombs have no such controls and are designed for maximum energy release. Fuel Enrichment: Nuclear reactors typically use low-enriched uranium or plutonium as fuel, while nuclear bombs require highly enriched uranium or plutonium to achieve a rapid, explosive chain reaction.
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
