KAERI is developing disposal technologies for spent fuels and the high-level radioactive wastes produced during the process of a spent fuel treatment.
A geological disposal technology to place high-level radwastes in corrosion resistant metal containers and seal and separate them in deep and stable underground caverns is a prerequisite.
KAERI is conducting research on the development of a disposal system suitable for the Korean environment and on a verification of its safety for high-level radioactive wastes. To this end, an underground disposal research facility was constructed in November 2006.
- Construction of the KAERI Underground Research Tunnel (KURT)
- Development of an engineered barrier system composed of a
disposal container, a buffer material and a back-filling material
- Prevention of the release of radioactive materials to the
environment by introducing a multi-layer barrier concept
- Research on the underground water behavior of a rock floor
