HTGRs are characterized by their unique use of helium as a coolant and graphite as a moderator. This combination enables them to operate at higher temperatures (up to 950°C) than conventional reactors, resulting in improved thermal efficiency and reduced fuel consumption. Additionally, the use of helium as a coolant eliminates the risk of coolant boiling, enhancing safety and reliability.

Other key benefits of HTGRs include:

* Enhanced Efficiency: The high operating temperatures allow for more efficient conversion of heat into electricity, reducing fuel requirements and minimizing operating costs. * Passive Safety Features: The inherent safety characteristics of HTGRs, such as the use of graphite as a moderator and the absence of coolant boiling, reduce the likelihood of accidents and make them inherently safe to operate. * Fuel Flexibility: HTGRs can utilize a wide range of fuels, including uranium, thorium, and plutonium, which provides fuel resource flexibility and reduces dependence on a single fuel source. * Advanced Applications: HTGRs have the potential to be used in various applications beyond electricity generation, such as process heat for industrial processes, hydrogen production, and desalination.
