GRM
GRM (Generalised Repository Model) is a biogeochemical model
principally applied to the near-field of LLW and ILW repositories.
Functionality includes:
- Comprehensive microbiological model of organic degradation
processes
- Corrosion modelling of metallic wastes and containers
- Microbial mediation of redox reactions e.g. sulphate reduction,
iron reduction and hydrogen utilisation
- Equilibrium geochemical speciation
- Radionuclide speciation, solubility and mechanistic
sorption
- Assessment of Carbon-14 release, transport and reactivity
- Gas generation considering corrosion, microbiology and
solubility
- Finite difference representation of waste and repository
heterogeneity
- Coupling of reactive processes with groundwater transport
Applications of GRM include:
- Drigg 2002 Post-Closure Safey Case
- Support to licences for landfill disposal
- Modelling of gas generation from ILW/LLW, Finland
