The shell side heat transfer and pressure drop to water flowing parallel with the Eggcrate Support Plate was experimentally investigated in order to get higher performance for the cooler in a Boiling Water Reactor power plant. The following three conclusions were reached in the study. (1) The shell side heat transfer characteristics with the Eggcrate Support Plate were twice as large as those of the shell side parallel flow. An equation using the Reynolds number of the Eggcrate Support Plate could predict the heat transfer coefficient. (2) The shell side pressure drop characteristics with the Eggcrate Support Plate were about five to six times as large as those of the shell side parallel flow. (3) The enhancement constant of heat transfer with the Eggcrate Support Plate, using the Colburn's j factor and friction factor f, was the same as that of the ROD-baffle type, and was about two times as large as that of the segmental baffle type.
