Correlations between the amount of DAW (Dry Active Waste) generated from present Korean PWRs and their operating parameters were analyzed. As the result of multi-variable linear regression. s, a model predicting the volume of DAW using the number of shutdowns (frs) and total personnel exposure (PE) was derived. Considering one standard error bound, the model could successfully simulate about 85% of the real data. In order to predict the amount of DAW to be generated from a KNGR, another model was derived by taking into account the additional volume reduction by supercompaction system. In addition, the volume of WAW (Wet Active Waste) to be generated from KNGR (Korean Next Generation Reactor) was calculated by considering conceptual design data and replacement effect of radwaste evaporator with selective ion exchangers. Finally, total volume of SRW (Solid Radioactive Waste) to be generated from KNGR was predicted by inserting design goal values of fFs and PE into the model. The result showed that the expected amount of SRW to be generated from KNGR would be in the range of 33 ~ 44 m3 y-1. It was proved that the value would meet the operational target of KNGR proposed by KEPCO, that is, 50 m³ y-1.
