SAFETY ASSESSMENT CODES FOR THE NEAR-SURFACE DISPOSAL OF LOW AND INTERMEDIATE-LEVEL RADIOACTIVE WASTE WITH THE COMPARTMENT MODEL: SAGE AND VR-KHNP

Based on the conceptual design of a near-surface disposal facility for Low- and Intermediatelevel radioactive waste in Korea, safety assessment code called SAGE was developed and intensive efforts for program verification and validation has been made. With this regards, VRKHNP which is recently developed based on multi-compartment model is benchmarked with SAGE. Through the comparison of radionuclide release rate at near- and far-filed, two computer codes show good agreement.
