This study presents a practical application of complementary safety indicators, which can be applied in asafety assessment of a radioactive waste repository by excluding a biosphere simulation and comparingthe artificial radiation originating from the repository with the background natural radiation. Complementarysafety indicators (radiotoxicity flux from geosphere and radiotoxicity concentration in seawater)were applied in the safety assessment of a rock-cavern type low and intermediate level radioactive waste(LILW) repository in the Republic of Korea. The natural radionuclide (40K, 226,228Ra, 232Th, and 234,235,238U)concentrations in the groundwater and seawater at the Gyeongju LILW repository site were measured. Based on the analyzed concentrations of natural radionuclides, the levels of natural radiation weredetermined to be 8.6 10 5 e 8.0 10 4 Sv/m2/yr and 6.95 10 5 Sv/m3 for radiotoxicity flux from thegeosphere and radiotoxicity concentration in seawater, respectively. From simulation results obtainedusing a Goldsim-based safety assessment model, it was determined that the radiotoxicity of radionuclidesreleased from the repository is lower than that of the natural radionuclides inherently present inthe natural waters. The applicability of the complementary safety indicators to the safety case wasdiscussed with regard to reduction of the uncertainty associated with biosphere simulations, andcommunication with the public.
