Climate change and safety at work with ionizing radiations

Area of Science:

• Nuclear Safety
• Climate Change Adaptation
• Risk Management

Background:

• The Fukushima Daiichi nuclear power plant (NPP) accident highlighted risks from external natural events.
• Climate change increases the probability of extreme weather, posing new threats to nuclear facilities and workers.
• Extreme natural events can compromise safety systems, procedures, and communication during emergencies.

Purpose of the Study:

• To emphasize the growing risks to nuclear facilities due to climate change-induced extreme natural events.
• To highlight the need for enhanced safety measures and adaptation strategies in the nuclear sector.
• To promote a evolving nuclear safety culture that accounts for external event risks.

Main Methods:

• Review of nuclear safety principles in light of external event risks.
• Analysis of climate change impacts on nuclear power plant (NPP) vulnerability.
• Examination of emergency preparedness and response challenges during extreme natural events.

Main Results:

• Extreme natural events present significant threats to nuclear power plants (NPPs) and facilities handling radioactive materials.
• Climate change exacerbates the vulnerability of nuclear sector workers and infrastructure.
• Current safety protocols may be insufficient to address the escalating risks from climate-related extreme events.

Conclusions:

• Adaptation strategies are crucial for managing climate change-related risks in the nuclear industry.
• A comprehensive nuclear safety culture must integrate preparedness for both internal and external initiating events.
• Proactive measures are essential to ensure the safety and security of nuclear facilities in a changing climate.
