Metal Transport in the Environment (MetTrans)

Date du début: 1 févr. 2012, Date de fin: 31 juil. 2016,

Understanding the processes that control the transport of metals in the environment is essential for a wide range of fields, including environmental protection and remediation, mineral resources, climate change. Through recent analytical developments, it is possible, using natural variations in metal isotopes, to identify and quantify how metal concentrations in natural waters are controlled by in ...

Reducing Uncertainty in Performance Prediction (REDUPP)

Date du début: 1 avr. 2011, Date de fin: 31 mars 2014,

"At the core of the safety case for long-term geologic disposal for spent nuclear fuel lie the issues regarding spent fuel dissolution. We have today significant knowledge regarding dissolution of uranium oxide in the laboratory. However, uncertainties remain regarding spent fuel dissolution under realistic conditions. Two main questions stand out as necessary to address: First, the synthetic grou ...

Slow processes in close-to-equilibrium conditions for radionuclides in water/solid systems of relevance to nuclear waste management (SKIN)

Date du début: 1 janv. 2011, Date de fin: 31 déc. 2013,

"Solid/liquid chemical equilibrium hypotheses (sorption, solubility, solid-solution formation) are key concepts in the assessment of nuclear waste safety. For radionuclides at trace concentrations this corresponds to constant solution concentrations, or solid/liquid distribution ratios, if environmental conditions remain constant. However, these concepts do not account for irreversible incorporati ...

Fate of Repository Gases (FORGE)

Date du début: 1 févr. 2009, Date de fin: 30 sept. 2013,

"The multiple barrier concept is the cornerstone of all proposed schemes for underground disposal of radioactive wastes. The concept invokes a series of barriers, both engineered and natural, between the waste and the surface. Achieving this concept is the primary objective of all disposal programmes, from site appraisal and characterisation to repository design and construction. However, the perf ...
