While no energy source is entirely risk-free, nuclear energy ranks among the safest—comparable to solar and wind, and significantly safer than fossil fuels. In fact, research indicates that nuclear energy may have prevented more than 1.8 million deaths globally by reducing reliance on coal and other polluting fuels.
Over the last four decades, there have been no major incidents involving newly built nuclear reactors. Today’s nuclear facilities are equipped with advanced passive safety systems that operate automatically, without the need for human input or external power sources. Some next-generation reactors, using alternative coolants, offer even greater safety enhancements. For example, China has recently developed a reactor design that is resistant to meltdown scenarios.
Security is also a core principle in nuclear plant design. These facilities feature reinforced containment structures—often over a meter thick and made of steel-reinforced concrete—engineered to withstand extreme impacts, including the crash of a large commercial aircraft such as an Airbus A380. Beyond physical security, nuclear plants are fortified against modern cyber threats with sophisticated digital protections.
The combination of robust safety engineering, continuous innovation, and stringent regulatory oversight positions nuclear energy as a highly secure and dependable part of the global energy mix.
