SUMMARY

On December 14, 2002, the Callaway Plant experienced an automatic reactor trip on Over Temperature/Delta Temperature (OTDT). The trip occurred while completing a downpower from 100% to 85%, to secure the condensate pump for maintenance. While reducing power, OTDT penalty points resulted in a rod stop and turbine runback. Initial plant response was per design. The pump was repaired and the gain to the OTDT trip setpoint, was adjusted. On December 17, 2002, the plant was returned to service.
