DOI: 10.1016/j.anucene.2020.107335
Abstract: Abstract One of the core problems of waste canisters layout in high-level radioactive waste repository is the evolution of the temperature field. On basis of the layered thermal analysis model for single waste canister, the… read more here.

DOI: 10.1016/j.anucene.2020.107866
Abstract: Abstract In this paper, coupled governing equations were proposed to simulate three-dimensional heat conduction and moisture transport in the nuclear waste repository. Because there will be a large temperature gradient near inner and outer boundaries… read more here.

DOI: 10.1039/c7dt04824f
Abstract: Safety assessment studies of future nuclear waste repositories carried out in many countries predict selenium-79 to be a critical radionuclide due to its presence as anion in three relevant oxidation states (vi, iv, -ii) resulting… read more here.
