Similar Events

A loss of the ability to maintain Secondary Containment pressure greater than required by Technical Specifications has occurred at, and was reported by, Columbia Generating Station (Columbia) twice in the past two years. The first incident was the result of an incorrectly sized lug installed in the fuse block during initial construction and the second incident occurred when an exhaust air valve unexpectedly closed. 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 Causal evaluation determined that the failure of the fan was a result of a faulty control switch; corrective actions are to replace the control switch for fan REA-FN-1 B. Additionally, the control switches for the System A exhaust air fan and both Reactor Building supply air fans will be replaced as well, as they are the same make, model, and age as the control switch in fan REA-FN-1 B.
