Because of its high-temperature capability, advanced stage of development relative to other high-temperature reactor concepts, and passive safety features, the Modular Helium Reactor (MHR) is well suited for producing hydrogen using nuclear energy. Process heat from the MHR at temperatures in the range 850 deg. C to 1000 deg. C can drive the sulfur-iodine (SI) thermochemical process to produce hydrogen with high efficiency. The MHR can also produce electricity with high efficiency, when coupled directly to a gas turbine that drives a generator. This electricity can be used to generate hydrogen using low-temperature electrolysis (LTE). Hydrogen can also be produced with hybrid processes that use both process heat and electricity. An example of a hybrid process is high-temperature electrolysis (HTE), which is of interest because the efficiency of electrolysis increases with temperature. In this paper we investigate MHR-based hydrogen production systems that involve coupling the MHR to the SI process, LTE, and HTE. (authors)
