Risk Hierarchy

INES 0

Deviation

Minimal risk. Operating below normal thresholds.

INES 1

Anomaly

Minor deviation from normal operation. Correctable.

INES 3

Serious Incident

Exposure beyond regulatory limits. Containment intact.

INES 5

Wider Consequences

Partial core damage. Significant radiation release.

INES 7

Major Accident

Widespread environmental release. Long-term impact.

Learning Objectives

Safety Systems

Modern reactors employ defense-in-depth: passive cooling, redundant control systems, and containment barriers. Understanding these mechanisms is essential for evaluating nuclear safety.

Risk Assessment

Risk = Probability × Consequence. Nuclear accidents are rare but severe. Context matters: coal kills more people annually, but predictably. Understanding probabilistic thinking enables informed energy policy decisions.

Engineering Ethics

Engineers face trade-offs: cost, safety, efficiency. The nuclear industry's responses to Fukushima demonstrate post-incident improvement. Critical thinking about engineering decisions shapes future energy systems.

Knowledge reduces fear.
Understanding enables choice.
