Criticality Accident - Accident Types

Accident Types

Criticality accidents are divided into one of two categories:

  • Process accidents, where controls in place to prevent any criticality are breached;
  • Reactor accidents, where deliberately achieved criticality in a nuclear reactor becomes uncontrollable. Excursion types can be classified into four categories depicting the nature of the evolution over time:
  1. Prompt Criticality Excursion
  2. Transient Criticality Excursion
  3. Exponential Excursion
  4. Steady State Excursion
