Another example is metallic fuel, which has a high thermal conductivity and can quickly dissipate heat, reducing the risk of fuel melting. By using these advanced fuel designs, new nuclear reactor technology minimizes the potential for fuel damage and the release of radioactive materials, even in the event of an accident.

Robust containment structures are another essential safety mechanism in new nuclear reactor technology. These structures are designed to withstand extreme events such as earthquakes, tsunamis, and even aircraft impacts. They are typically made of reinforced concrete and steel and are designed to contain any radioactive materials that may be released during an accident. Some reactors also have a double containment structure, which provides an additional layer of protection. These robust containment structures ensure that radioactive materials are contained within the reactor building, preventing their release into the environment.

In addition to these physical safety mechanisms, new nuclear reactor technology also incorporates advanced monitoring and control systems that provide real-time information about reactor conditions. These systems can detect anomalies and automatically initiate safety measures to prevent accidents. They also provide operators with the information they need to respond quickly and effectively to any incidents that may occur. By combining physical safety mechanisms with advanced monitoring and control systems, new nuclear reactor technology provides a comprehensive approach to ensuring reactor safety.
