The EPR, a standardized nuclear power plant design, was developed for deployment throughout the world. As a result of being engineered and constructed simultaneously, the standardized design was based on northern European climate conditions. However, an unforeseen effect on steam generator blowdown system was discovered when the standardized design was in development for tropical sites. Possible solutions to the issue are examined and addressed in this paper. A commercial heat balance program is used to model and examine the results of possible scenarios. The results are used to improve the standardized design for nuclear power plants located in tropical sites.
