Similar Events
A loss of the ability to maintain Secondary Containment pressure greater than required by Technical Specifications has occurred at Columbia Generating Station (Columbia) one time in the past two years, which was the result of a power supply failure. Prior to this two year time period, Columbia has experienced losses of Secondary Containment due to weather-related conditions, as well as human performance errors. Columbia has implemented corrective actions for these previous events.
Further Corrective Actions Additional corrective actions will be provided in a supplement to this LER following completion of the cause evaluation.
