US nuclear power plants set a new record for annual power generation in 2018. Capacity additions from plant uprates, combined with shorter refueling maintenance cycles, enabled the country’s nuclear plants to produce 807.1 million MWh in 2018, surpassing the previous peak figure of 807.0 million MWh which was recorded in 2010. Georgia Power’s Vogtle 3 and 4 – due to come online in 2021 and 2022 – will add 2.2 GWe of additional power, but this will not offset the capacity that is expected to retire over the next seven years based on announced retirements. Pilgrim in Massachusetts and Three Mile Island are expected to retire this year. Twelve reactors by 2025 will see US nuclear capacity fall by 10.5 GWe.
