NRC approves St. Lucie SLRs
The Nuclear Regulatory Commission has approved subsequent license renewals for St. Lucie Units 1 and 2, extending the operating licenses for the pressurized water reactors by another 20 years.
Tuesday’s approval means that the 1,062-MWe Unit 1 and 1,074-MWe Unit 2 can now operate until March 1, 2056, and April 6, 2063, respectively. Unit 1 commenced operations in 1976 and Unit 2 in 1983. With the original 40-year operating licenses and first 20-year renewals, these second 20-year renewals bring the reactors’ lifespan to 80 years.
