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:
- Prompt Criticality Excursion
- Transient Criticality Excursion
- Exponential Excursion
- Steady State Excursion
