Engineering thinking in emergency situations: A new nuclear safety concept

Area of Science:

• Nuclear Engineering
• Crisis Management
• Organizational Resilience

Background:

• The Fukushima Daiichi accident revealed limitations in traditional safety standards and crisis planning for nuclear events.
• Existing frameworks based on probabilistic risk assessment and disaster scenario identification proved insufficient for the prolonged crisis.

Purpose of the Study:

• To introduce and define the concept of "engineering thinking in emergency situations."
• To explore organizational capacity for adaptation in extreme, unforeseen circumstances.
• To propose future directions for nuclear safety oversight.

Main Methods:

• Analysis of organizational responses and adaptive strategies employed during the Fukushima Daiichi aftermath.
• Conceptual development of "engineering thinking in emergency situations" based on observed adaptations.
• Review of current nuclear safety oversight practices.

Main Results:

• Organizations demonstrated significant adaptability by creating temporary structures and shifting to innovative modes.
• Integration of social dimensions into engineering activities was observed as a key adaptive strategy.
• The study identified a gap between conventional safety standards and the requirements of prolonged, resource-scarce crises.

Conclusions:

• "Engineering thinking in emergency situations" requires adaptability, resilience, and the ability to innovate rapidly.
• Future nuclear safety oversight should evaluate operators' on-the-fly strategy development and demonstrated resilience.
• A proactive approach to fostering organizational resilience is essential for managing future nuclear accidents.
