Realistic Initiating Events for Advanced Reactors

Based on stakeholder discussions, there is currently a need for technical guidance related to the definition of various key types of initiating events for advanced reactors.

Research topics to be addressed include:

  • What are the challenging initiating event definitions for advanced reactors?
    • Include consideration of events for both design basis accidents and PRA
    • Include consideration of events originating within the nuclear facility and from external sources
    • Particular interest may relate to LOCA events and their assumed break frequencies
  • What modifications to current event definitions are needed to support specific advanced reactor safety analyses?
  • What uncertainties need to be treated for modified event definitions for advanced reactors?
