2012 License Renewal

The Nuclear Regulatory Commission issued a standard 40-year operating license to Energy Northwest's Columbia Generating Station in December 1983. In May 2012 the NRC approved Columbia's license for an additional 20 years, extending operation through 2043.

This was a significant accomplishment for Columbia, Energy Northwest and the agency’s employees. The renewal capped a five-year process requiring a tremendous amount of work.

Additional information on the U.S. nuclear power plants license renewal process is available on the NRC Website.
