Thermal behavior of groundwater-saturated Korean buffer under the elevated temperature conditions: In-situ synchrotron X-ray powder diffraction study for the montmorillonite in Korean bentonite

open access: yesNuclear Engineering and Technology, 2021
In most countries, the thermal criteria for the engineered barrier system (EBS) is set to below 100 °C due to the possible illitization in the buffer, which will likely be detrimental to the performance and safety of the repository. On the other hand, if

Geologic environments for nuclear waste repositories

open access: yesMATEC Web of Conferences, 2017
High-level radioactive waste (HLW) results from spent reactor fuel and reprocessed nuclear material. Since 1957 the scientific consensus is that deep geologic disposal constitutes the safest means for isolating HLW for long timescales.

Combustion synthesis of Hf-doped zirconolite-rich composite waste forms and the aqueous durability

open access: yesJournal of Advanced Ceramics, 2019
Zirconolite is recognized as one of the most durable waste matrices for the disposal of high-level radioactive wastes (HLWs). In this study, HfO2 was employed as the surrogate of tetravalent actinides.
