Recent concerns have been expressed about the safety of nuclear reactors. In 2012, the Union of Concerned Scientists, which tracks ongoing safety issues at operating nuclear plants, found that "leakage of radioactive materials is a pervasive problem at almost 90 percent of all reactors, as are issues that pose a risk of nuclear accidents".

Nuclear power compared to other sources of electricity in the US, 1949–2011. In the United States, nuclear power is provided by 94 commercial reactors with a net capacity of 97 gigawatts (GW), with 63 pressurized water reactors and 31 boiling water reactors. [ 1 ] In 2019, they produced a total of 809.41 terawatt-hours of electricity, [ 2 ...
Operation Dominic was a series of 31 nuclear test explosions ("shots") with a 38.1 Mt (159 PJ) total yield conducted in 1962 by the United States in the Pacific. [1] This test series was scheduled quickly, in order to respond in kind to the Soviet resumption of testing after the tacit 1958–1961 test moratorium.
Three Mile Island Unit 1. The Three Mile Island Unit 1 is a pressurized water reactor designed by Babcock & Wilcox with a net generating capacity of 819 MW e. The initial construction cost for TMI-1 was US$400 million, equal to $2.47 billion in 2018 dollars. [31] Unit 1 first came online on April 19, 1974, and began commercial operations on ...
