    Plan

  • Rappel titre - date- NX/Y

    Some scenarios of interest

    Nuclear accident (crisis) Acute release from a Nuclear Power Plant (NPP) Fate & transport of radionuclides in the neighboring continental environment

    (30 km, 3 years) Dose to man Efficiency of protection actions

    ERA 1

    SYMBIOSE Goldsim User Conference 2004

    Normal releases Long-term, low-level discharge of pollutants from a Waste Disposal Facility Fate & transport of pollutants in semi-natural ecosystems & geosphere Dose to fauna & flora Effects on biota populations (mortality & reproduction rates, etc.)

  • Rappel titre - date- NX/Y

    Trends in ERA modeling

    1. Integration Human Health &Biota Protection Radiological & chemical risk Multiple interacting media, spatially-distributed & dynamic systems Parametric vs structural uncertainties

    ERA 2

    2. Modularity Easy building of specific simulators Library of reusable modules Alternative modules (varying levels of complexity)

    3. Transparency (& Traceability) Modules content (structure, data & methods) Down to an appropriate level Reinforce confidence & credibility

    Collaborative development, User-friendliness
