Impact of Concrete Degradation on the Long-Term Safety of a Near-Surface Radioactive Waste Disposal Facility in Korea

open access: yesApplied Sciences, 2022
The migration of radionuclides from radioactive waste into the environment poses a public safety concern. Thus, the long-term safety assessment for near-surface disposal sites for radioactive waste in South Korea entails providing reasonable assurance ...

Groundwater migration of radionuclides at Fermilab [PDF]

open access: yes, 1993
The simple Single Resident Well (SRW) Model has been used to calculate groundwater movement since Fermilab`s inception. A new Concentration Model is proposed which is more realistic and takes advantage of computer modeling that has been developed for the siting of landfills.

Microorganisms and migration of radionuclides in environment

open access: yesComptes Rendus. Chimie, 2007
Amongst all the fission fragments, actinides and activation products coming from the nuclear energy processes, a dozen radionuclides are a hazard for Man and environment, due to their half-life and toxicity. For the last 3.5–4 billion years (Ga), microorganisms have been present on Earth in all sorts of surroundings, even the most hostile ones ...
