"COST-EFFECTIVE" THERMAL PERFORMANCE UPGRADE
OF THE CALLAWAY PLANT COOLING TOWER
U.A. LEES, JR., P.E. AND JOHN W. COOPER, JR., P.E.

In January 1994, Union Electric Company completed a successful two year project to upgrade the thermal performance efficiency of their 553 foot tall natural draft cooling tower. The counterflow cooling tower services Union Electric's 1233 MW Callaway Nuclear Power Plant near Fulton, Missouri. By implementing minor modifications to the cooling tower water distribution system and fill area, a substantial reduction in outlet water temperature was achieved at minimal cost. The engineering details for the cost-effective thermal upgrade design were developed utilizing color-coded exit air temperature and velocity mappings of the Callaway cooling tower as a diagnostic tool and modern computer modeling techniques as a design tool. In October and November of 1993, in the course of a scheduled refueling outage, all upgrade design modifications were implemented and routine maintenance work was completed. Immediately following the outage, color-coded exit air mappings of temperature and velocity were generated once again. These mappings showed the near total elimination of any cooling tower water distribution problems. These findings are consistent with the results of Union Electric Company's preliminary analyses that indicate that the cooling tower outlet water temperature has been reduced by 3oF at a project cost of less than $300,000.
