SUMMARY

South Texas Project Unit 1 began the reporting period operating at full power. On January 23, at 1616 the unit experienced an automatic reactor trip caused by high water level in Steam Generator IB. The event was induced by the failure of a ferro resonant transformer in the inverter, which supplies power to distribution panel 1201. The inverter was replaced and the unit was returned to service on January 26, at 1530. Full power was achieved on January 27, at 1529.
