The modular helium reactor for future energy needs (original) (raw)

2006

Abstract

The Modular Helium Reactor (MHR) is one of the advanced reactor concepts within the internationally-supported Generation IV program. Because of its design features and design maturity, the MHR was selected by the U.S. Department of Energy (DOE) as the U.S. Generation IV design concept for the Next Generation Nuclear Plant (NGNP). Other countries, including Russia, Japan, South Korea, China, South Africa, and France are also developing this technology, and large-scale deployment of MHR technology is a realistic element of future energy-growth scenarios. In this paper, we discuss MHR conceptual designs for electricity and hydrogen production and their role in a sustainable energy future with significant growth in nuclear energy. For hydrogen production, two conceptual designs are described; one coupling the MHR to thermochemical water splitting using the sulfur-iodine (SI) process and the other coupling the MHR to high-temperature electrolysis (HTE).
