After the Fukushima Daiichi accident, the U.S. Nuclear Regulatory Commission (NRC) issued 10 CFR 50.54(f), a letter requiring licensees to perform a reevaluation of seismic hazard and take further actions if it exceeds their design basis. In response to this letter, Columbia Generating Station (CGS) undertook an evaluation of the spent fuel pool (SFP) integrity for the new seismic hazard.
