Nuclear Energy for Hydrogen Generation through Intermediate Heat Exchangers

This book describes recent technological developments in§next generation nuclear reactors that have created renewed interest in nuclear§process heat for industrial applications. The author's discussion mirrors the industry's§emerging focus on combined cycle Next Generation Nuclear Plants' (NGNP) seemingly§natural fit in producing electricity and process heat for hydrogen production. To§utilize this process heat, engineers must uncover a thermal device that can§transfer the thermal energy from the NGNP to the hydrogen plant in the most performance§efficient and cost effective way possible. This book is written around that§vital quest, and the author describes the usefulness of the Intermediate Heat§Exchanger (IHX) as a possible solution. The option to transfer heat and thermal§energy via a single-phase forced convection loop where fluid is mechanically§pumped between the heat exchangers at the nuclear and hydrogen plants is§presented, and challenges associated with this tactic are discussed. As a second§option, heat pipes and thermosyphons, with their ability to transport very§large quantities of heat over relatively long distance with small temperature§losses, are also examined.§
