The Ki-Jang research reactor (KJRR), a new research reactor in Korea, is being planned to fulfill multiplepurposes. In this study, as an assessment of the environmental radiological impact, we characterized theatmospheric dispersion and deposition of radioactive materials released by an unexpected incident atKJRR using the weather research and forecastingemesoscale model interface programeCaliforniaPuff (WRFeMMIFeCALPUFF) model system. Based on the reproduced three-dimensional griddedmeteorological data obtained during a 1-year period using WRF, the overall meteorological data predictedby WRF were in agreement with the observed data, while the predicted wind speed data wereslightly overestimated at all stations. Based on the CALPUFF simulation of atmospheric dispersion (c/Q)and deposition (D/Q) factors, relatively heavier contamination in the vicinity of KJRR was observed, andthe prevailing land breeze wind in the study area resulted in relatively higher concentration anddeposition in the off-shore area sectors. We also compared the dispersion characteristics between thePAVAN (atmospheric dispersion of radioactive release from nuclear power plants) and CALPUFF models. Finally, the meteorological conditions and possibility of high doses of radiation for relatively higherhourly c/Q cases were examined at specific discrete receptors.
