This study was conducted to analyze the characteristics of three high-exposure tasks performed byradiation workers in Korean pressurized water reactors (PWRs) and to identify factors that reduce their exposureduring work. Three high-exposure tasks were selected based on a previous study. In this previous study, nozzle daminstallation and removal, eddy current testing, and manway opening and closing were determined as high-exposuretasks through normalization (radiation dose per unit time). Based on the analysis of the characteristics of the highexposuretasks in this study, the high-exposure tasks were steam generator-related tasks performed inside and outsidethe water chamber. This study analyzed the reduction factors for high-exposure tasks and suggested improvements interms of time, distance, and shielding. The use of the characteristics of high-exposure tasks and their dose reductionfactors enables Korean PWRs to optimize radiation protection for workers who receive relatively high doses.
