Nuclear power in the United States
De amerikanske atomreaktorer havde oprindeligt en 40-årig driftstilladelse. I 1980'erne fastslog NRC, at der ikke var nogen tekniske problemer, der ville udelukke længere drift. Over halvdelen af de amerikanske atomreaktorer er over 30 år gamle, og næsten alle er over 20 år gamle. I 2011[opdatering] havde mere end 60 reaktorer fået forlænget deres tilladte levetid med 20 år. Den gennemsnitlige kapacitetsfaktor for alle amerikanske reaktorer er forbedret fra under 60 % i 1970'erne og 1980'erne til 92 % i 2007,

Nuclear power in the United States
US nuclear reactors were originally licensed to operate for 40-year periods. In the 1980s, the NRC determined that there were no technical issues that would preclude longer service. Over half of US nuclear reactors are over 30 years old and almost all are over twenty years old. As of 2011[update], more than 60 reactors have received 20-year extensions to their licensed lifetimes. The average capacity factor for all US reactors has improved from below 60% in the 1970s and 1980s, to 92% in 2007,
