This is a different type of reactor using a different type of fuel. FTFA: "The concept for the reactors began with the requirement that they would run off of tristructural isotropic particle fuel, or TRISO...Each TRISO particle is made up of a uranium, carbon and oxygen fuel kernel which is encapsulated by three layers of carbon- and ceramic-based materials that prevent the release of radioactive products" and then further down... "The fuel has two secondary benefits...the first being its resiliency to proliferation which can help deter the reactors from being targets for bombings or attacks.”
