2026 FRI3D / RiskSpectrum Online Workshop
A hands-on, ~3-hour online workshop covering fire modeling and fire PSA with FRI3D and RiskSpectrum — from the fundamentals through building a model, running scenarios, and quantifying risk. Hosted by our RiskSpectrum distributor, with one short break in the middle.
Who it's for: fire-PRA analysts, reactor-safety and PSA engineers, and anyone evaluating FRI3D for nuclear (and SMR) fire risk assessment.

Agenda
The workshop runs about three hours with a short break in the middle. Session lengths are shown below; your distributor schedules the exact date and time.
| # | Session | Topics covered | Duration |
|---|---|---|---|
| 1 | Introduction to Fire Modeling & FRI3D | What FRI3D is and why; deterministic vs. performance-based (NFPA 805); the NUREG-6850 fire-PRA process and where FRI3D automates it | 30 min |
| 2 | Fire Calculations & Methods | Cable-failure methods — heat soak, THIEF, FLASH-CAT; CFAST fire-simulation coupling | 25 min |
| 3 | Fire PSA & Importing Plant Data | Fire logic and plant data; importing an XLS/Access database and a CAD model; linking the model to RiskSpectrum | 25 min |
| — | Break | 15 min | |
| 4 | Building a Model in FRI3D | UI & inspectors; compartments, raceways, cables, equipment, vents, sources; materials, failure criteria, heat-release rates; 3D modeling | 45 min |
| 5 | Scenarios, Simulation & RiskSpectrum | Manual and automated (CFAST) scenarios, results and timeline; ignition frequency, severity factor, non-suppression, CCDP/CDF; solving with RiskSpectrum | 25 min |
| 6 | Concluding Remarks & Roadmap | The FRI3D roadmap, and extending the integrated 3D + PSA approach beyond fire — internal/external flooding, explosions, and other hazards; Q&A | 15 min |
