Services
PFLOTRAN Reactive Transport Modelling
End-to-end PFLOTRAN simulations covering single-phase and multiphase flow, heat transport, and reactive geochemistry. From input file construction to results interpretation and reporting.
THMC Coupled Simulations
Thermal-hydrological-mechanical-chemical modelling using OpenGeoSys with IPhreeqc coupling. Suitable for engineered barrier systems, buffer swelling, and near-field repository analysis.
Performance Assessment
Long-term safety case modelling for geological disposal facilities. Radionuclide source term definition, transport pathway analysis, and biosphere dose calculations (ICRP 119 basis).
Uncertainty Quantification
Dakota-driven probabilistic analysis including Latin Hypercube Sampling, variance-based sensitivity analysis, and surrogate-assisted optimisation.
Geochemical Modelling
PhreeqPy/PHREEQC-based speciation, Kd estimation, pH sweeps, and porewater chemistry analysis relevant to waste form stability and radionuclide sorption.
Consulting & Review
Independent review of existing models, input files, and safety case documentation. Expert opinion on PFLOTRAN, OGS, MODFLOW, and related subsurface codes.
