The Nuclear Regulatory Commission said Aug. 26 that it has published its final review detailing the environmental impacts of renewing the operating licenses of LaSalle Units 1 and 2 in Illinois.
The supplemental environmental impact statement contains the NRC staff’s conclusion that the impacts would not preclude renewing the plant’s licenses for an additional 20 years. LaSalle County Station, located 11 miles southeast of Ottawa, has two boiling-water reactors. The operator, Exelon Generation, submitted the renewal application on Dec. 9, 2014.
The NRC’s review of the application consists of a technical safety review and the environmental review. The NRC published a draft version of the environmental report in February for public comment. The final report includes the staff’s responses to the comments.
The existing licenses (NPF-11 and NPF-18) expire on April 17, 2022, and Dec. 16, 2023, respectively. LaSalle is a two-unit facility that began commercial operation in January 1984 (Unit 1) and October 1984 (Unit 2). Both units have General Electric boiling water reactors, and together they produce an annual average net output of 2,327 megawatts electric (MWe).
LaSalle is located in rural LaSalle County in northern Illinois about 75 miles southwest of Chicago. LaSalle’s Unit 1 is capable of generating 1,161 net MW, while Unit 2 is capable of generating 1,159 net MW.
