Assessment of Safety Consequences
This event did not challenge the ability of Columbia Generating Station to safely shutdown, and all plant systems responded as designed. Human performance issues resulted in a trip of RCIC, and an automatic transfer of power supplies to backup power supplies per design. The reactor scram and resulting transient caused a loss of RPS which resulted in a full safety system actuation and a reduction of cooling to the PC. The trip of RCIC was not consequential since HPCS was available, and was used, to maintain RPV level. The power supplies transferred to backup power supplies as designed. The reduction of cooling to the PC did not challenge PC integrity, and was restored by operator action. There were no adverse impacts to those systems due this event. There were no undesired radiological or industrial safety aspects resulting from this event.
