The Nuclear Regulatory Commission is issuing for public comment a draft plant-specific Supplement 57 to the Generic Environmental Impact Statement (GEIS) for renewal of two licenses for an additional 20 years of operation of LaSalle County Station (LSCS) Units 1 and 2.
Exelon Generation Co. LLC‘s LaSalle plant is located in LaSalle County, Illinois. Possible alternatives to the proposed action (licenses renewal) include no action and reasonable alternative energy sources. The NRC said in a notice to be published in the Feb. 11 Federal Register that its staff plans to hold a public meeting during the public comment period to present an overview of the draft plant-specific supplement to the GEIS. Comments are due by April 4. The meeting will be held at the LaSalle County Emergency Operations Center on March 22.
The NRC’s preliminary recommendation is that the adverse environmental impacts of license renewal for LSCS are not great enough to deny the option of license renewal for energy-planning decisionmakers.
In December 2014, Exelon Generation submitted an application to issue these renewed operating licenses. The existing licenses (NPF-11 and NPF-18) expire on April 17, 2022, and Dec. 16, 2023.
LSCS is a two-unit facility that began commercial operation in January 1984 (Unit 1) and October 1984 (Unit 2). The nuclear reactors at both units are General Electric boiling water reactors (BWRs), and together they produce an annual average net output of 2,327 megawatts electric (MWe).
In preparation for its license renewal application, Exelon performed an evaluation of LSCS structures, systems, and components to identify whether any major refurbishment activities would be necessary to support the continued operation of LSCS during the proposed 20-year period of extended operation. Exelon did not identify any major refurbishment or replacement activities needed to support continued operation of the plant, said the draft GEIS.
The plant is located in rural LaSalle County in northern Illinois about 75 miles southwest of Chicago. Unit 1 is capable of generating 1,161 MW (net), while Unit 2 is capable of generating 1,159 MW (net). Exelon Generation is a unit of Exelon Corp. (NYSE: EXC).
