High-Temperature Gas-Cooled Reactor (HTGR)—The HTGR, shown in Figure 4.20, uses pressurized helium gas to transfer heat from the reactor to a steam-production system. The advantage of helium gas over water is that the helium can operate at much higher temperatures.

The high-temperature gas-cooled reactor (HTGR) is one technology concept among the advanced reactors that includes the most effective technologies to meet the future of nuclear energy. Thanks to its robust and resilient coated-particle fuel form combined with a gas coolant and graphite-moderated core, this design allows for operation at temperatures that may exceed 1000°C (Ref. 1). As a consequence, this reactor technology can achieve higher thermal efficiency when compared to other advanced concepts and existing commercial reactors. Furthermore, such temperatures are high enough for processes requiring high heat as input, e.g., hydrogen production and water desalination. As such, this reactor has attracted the attention of the industry community.

Nuclear power has been a promising energy supply considering its high power density and greenhouse gas emission-free features. With approximately 450 reactors providing about 17% of the world’s electricity,1 new nuclear power reactors have constantly been developed, and it has now been advanced into the fourth stage. The High-Temperature Gas-cooled Reactor (HTGR), as one of the six designs on the road map, has been selected due to its compatibility with high-efficiency electricity production and nuclear-assisted hydrogen production. Yet, there are many challenges before the HTGR deployment, and efforts are being made to mature this design and improve its reliability.2,3

Nuclear energy has been reevaluated in recent years as a clean and reliable energy source. In particular, the high-temperature gas-cooled reactor (HTGR) has been gaining attention as an innovative nuclear energy system that is capable of versatile nuclear heat applications, including hydrogen production without CO2 emissions.1 The future deployment of commercial HTGRs is expected to be part and parcel of the carbon emission neutrality that many countries are targeting.
