Most U.S. nuclear plants would retire by 2050 without another extension

Despite the fact that most U.S. nuclear plants have already received license extensions from the Nuclear Regulatory Commission (NRC) most could still be retiring by 2050 within a second life extension, according to the Energy Information Administration (EIA).

Domestic nuclear plants are initially licensed to run for 40 years. Beyond that the reactors need to have license extensions issued by the NRC.

NRC has already issued license renewals for 74 of the 100 nuclear units now operating in the United States.

“With the bulk of the existing nuclear fleet licensed before 1990, nearly all existing reactors will be more than 60 years old by 2050,” EIA in a Dec. 8 posting.

These reactors represent more than 69,000 MW of capacity, EIA said.

Thus far no U.S. nuclear units have applied to operate for more than 60 years, Dominion (NYSE:D) and Exelon (NYSE:EXC) are said to be considered subsequent license renewals to keep some plants running until age 80.

Dominion is looking for an additional license extension for its Surry units in Virginia and Exelon is considering such a move for its Peach Bottom Units 2 and 3 in Pennsylvania, EIA said.
