Environmental impact of radioactive waste

Radioactive waste management is one of the most regulated and controlled aspects of the nuclear cycle, to protect the environment and human health.

These radiation-emitting materials are handled under very strict international protocols that seek to minimise any risk.

Environmental impact is reduced through a system of multiple barriers:

• Specialised containers made of steel and concrete, designed to withstand radiation, corrosion, and extreme conditions.
• Secure storage in guarded facilities, with continuous monitoring and redundant systems to prevent leaks.
• Natural geological barriers, such as stable rock formations, act as additional protection in deep repositories.

Below are some of the organisations that ensure the safe management of radioactive waste from generation to storage:

• IAEA (International Atomic Energy Agency): Sets global standards for the safe management of radioactive waste and monitors compliance.
• EURATOM (European Atomic Energy Community): Regulates nuclear safety in the European Union and promotes cooperation between Member States.
• ENRESA (Spain): Responsible for radioactive waste management and the decommissioning of nuclear facilities in Spain.
• WNA (World Nuclear Association): Provides technical information and best practices at the international level.
• ARN (Nuclear Regulatory Authority, Argentina): Oversees nuclear safety and waste management in Argentina.
• CNEN (National Nuclear Energy Commission, Brazil): Regulates radiological and nuclear safety in Brazil.
• CNSNS (National Commission for Nuclear Safety and Safeguards, Mexico): Responsible for regulating and controlling nuclear safety in Mexico.
• National authorities and regulatory bodies: Each country has entities that oversee the application of regulations and safety at all stages.

Thanks to these measures and organisations, the risk to the environment and the population remains extremely low, even in long-term scenarios.

Safety depends not only on technology, but also on transparency and international oversight, which ensure that waste is managed responsibly and sustainably. This approach allows nuclear energy to remain a viable option in the energy transition, without compromising the protection of the planet.
