About
AI Spectral is a specialised subsurface modelling consultancy focused on the nuclear waste management and geological disposal sector.
Our work draws on hands-on experience with the full OPERA-equivalent software stack: PFLOTRAN for reactive transport, OpenGeoSys for coupled THM/THMC, Dakota for uncertainty quantification, and PHREEQC for geochemical analysis — the same tools used in national geological disposal programmes in Canada, the Netherlands, Sweden, and Finland.
Capabilities
- PFLOTRAN — reactive transport, multiphase flow, GIRT radionuclide transport
- OpenGeoSys — THM/THMC with IPhreeqc tight coupling
- Dakota — LHS sampling, EGO optimisation, variance-based sensitivity analysis
- MODFLOW 6 — saturated groundwater flow and transport
- OpenMC — Monte Carlo neutron transport and criticality assessment
- PHREEQC / PhreeqPy — geochemical speciation and Kd modelling
- ParaView — 3D visualisation of simulation output
