Korean nuclear power plants (NPPs) have various radiation protection programs to attain radiationexposure as low as reasonably achievable (ALARA). In terms of ALARA, this paper provides a comprehensiveoverview of administrative dose control for occupationally-exposed workers in Korean NPPs. Inaddition to dose limits, administrative dose constraints are implemented to resolve an inequity of radiationexposure in which some individuals in NPPs receive relatively higher doses than others. Occupationaldose constraints in Korean NPPs are presented in this paper with the background of how thosevalues were determined. For pressurized water reactors, 80% and 90% of the annual average limit for aneffective dose, 20 mSv/y, are set as the primary and secondary dose constraints, respectively. Pressurizedheavy water reactors (PHWRs) have also established the primary and secondary dose constraints correspondingto 70% and 80% of the effective dose limit, and additional constraints for tritium concentrationare provided to control internal exposure in PHWRs. Follow-up measures for exceeding theseadministrative dose constraints are also introduced compared to exceeding the dose limits. Finally,analysis results of dose distributions show how the implementation of administrative dose constraintsimpacted the occupational dose distributions in Korean NPPs during the years 2009e2018.
