Antranova Engineering AB
Advanced technical simulation and engineering analysis

Expertise

The competence profile focuses on decision support in complex systems: analysis, simulation, model development, and documentation with emphasis on traceability.

Wording and examples are intentionally kept general due to confidentiality.

Core expertise at a glance

  • Dynamic analysis: operating changes, transients, off-normal scenarios, and root-cause support.
  • Model development: structure, parameterization, calibration, and quality assurance.
  • Safety/Risk: assumptions, sensitivity, plausibility checks, and review packages.
  • Automation: runs, result collection, and report generation.
  • Pedagogy: technical material, example models, and training support.
  • Technical communication: clear reports, appendices, figures/tables, and structured narratives.

Full-scope simulators and reactor models

Experience includes development and maintenance of full-scope simulators for energy production facilities, including model integration, logic, and testability within simulator platforms.

Specialisation includes building and quality-assuring reactor models using RELAP5-3D and S3R, with emphasis on traceable assumptions, reproducible runs, and review-ready deliverables.

Delivery capability

  • Structured reports: clear layout, appendices, tables, and figures.
  • Reproducible packages: scripts/notebooks/Excel when appropriate.
  • Review readiness: explicit assumptions, version IDs, and traceable inputs.
  • Risk-based QA: from rapid expert support to expanded verification/peer review.

Tools & ways of working

Deliveries are adapted to client environments and requirements. Typical formats and tools include:

  • Python (scripts), Jupyter Notebooks, Excel/VBA
  • Model-based tools (e.g., Modelica/OpenModelica) when appropriate
  • Version control, run logging, and change logs when needed
  • Reporting in PDF/DOCX with appendices, tables, figures, and traceability

Assignments are always scoped with confidentiality and conflict-of-interest considerations.
