Cost-benefit analysis for regulatory clearance of VLLW metal radwastes at KAERI

The total amount of metal radwastes was about 40 tonnes, all of them were cleared by regulatory clearance in 2015. In this study, the cost for the clearance and the disposal cost saving were analysed, and, based on that, the economic efficiency of the regulatory clearance was discussed. There have been recent increases in the type and amount of radwastes considered for regulatory clearance in Korea. Metal radwastes account for most of the primary radwastes subject to regulatory clearance. At KAERI, a variety of metal radwastes with extremely low radioactivity were generated from nuclear facilities. The metal radwastes about 40 tonnes were cleared by regulatory clearance in 2015.The regulatory clearance was conducted in the form of committed disposal for recycling. By use of regulatory clearance, the disposal costs for radwastes were greatly saved.
