This safety evaluation report (SER) documents the technical review of the Columbia Generating Station (Columbia), license renewal application (LRA) by the U.S. Nuclear Regulatory Commission (NRC) staff (the staff).  By letter dated January 19, 2010, Energy Northwest (the applicant) submitted the LRA in accordance with Title 10, Part 54, of the Code of Federal Regulations, “Requirements for Renewal of Operating Licenses for Nuclear Power Plants.”  Energy Northwest requests renewal of the operating license (Facility Operating License Number NPF-21) for a period of 20 years beyond the current license period of December 20, 2023. 

Columbia is located approximately 12 miles north of Richland, WA.  The NRC issued the construction permit on March 19, 1973, and the operating license for Columbia on April 13, 1984.  The unit is a Mark II boiling-water reactor (BWR) design.  General Electric Company supplied the nuclear steam supply system.  Burns and Roe, Inc., designed the balance of plant, and Bechtel Power Corporation constructed the plant.  The licensed power output of the unit is 3,886 megawatts thermal, with a gross electrical output of approximately 1,230 megawatts electric. 

This SER presents the status of the staff’s review of information submitted through January 4, 2012.  The six open items previously identified by the staff from the SER with open items have been closed (see SER Section 1.5); the staff did not identify any open items before the staff made a final determination.  SER Section 6.0 provides the staff's final conclusion of the LRA review.
