2026 FRI3D / RiskSpectrum Online Workshop
A hands-on, ~3-hour online workshop covering fire modeling and fire PSA with FRI3D andRiskSpectrum — from the fundamentals through building a model, running scenarios, andquantifying risk. Hosted by RiskSpectrum (www.riskspectrum.com), 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.
