TRISO fuel is composed of tiny ceramic kernels with 6% uranium oxide, encapsulated in four layers of highly resistant ceramics, making it almost impossible for radioactive waste to be released, even in accidents. These ceramics are heat resistant, requiring temperatures of several thousand degrees Fahrenheit to decompose, preventing meltdowns. In a simulation by Japan, the TRISO fuel survived a catastrophic failure test, reaching 2,400 °F and passively cooling to 2,372 °F, showcasing a safety margin of at least one week without human intervention.
High-Temperature Gas-Cooled Reactors (HTGRs) offer unprecedented safety in nuclear power, potentially heralding a global return to nuclear energy. Despite their waste production similar to older technologies, the main challenge lies in managing this waste for thousands of years. While uncertainties exist in scaling the technology, overcoming design-specific challenges through engineering innovation remains promising for a bright future in nuclear energy.
