Conceptual Design Study of a Hydrogen Production Plant with a Sodium Cooled Reactor Using Membrane Reformer

Chikazawa, Yoshitaka  ; Hori, Toru; Konomura, Mamoru; Sato, Hiroyuki*; Uchida, Shoji*

In phase II of a feasibility study of JNC, we are finding a concept of a multi-purpose small sized reactor with various requirements, such as, economical competitiveness and safety. In the previous study, hydrogen production using hydrogen separation reformer was studied as one of promising concepts. In this study, a conceptual design study of a hydrogen and electric co-production plant has been done. The reactor thermal output is 375 MW and 25% of the thermal output is used for hydrogen production (70000 Nm$$^{3}$$/h). The hydrogen production cost is estimated 21 yen/Nm$$^{3}$$ that is higher than the economical goal of 17 yen/Nm$$^{3}$$. The major reason of the high cost is the large hydrogen separation reformer because of the limit of hydrogen separation efficiency of palladium membrane. The development of a new high efficiency hydrogen separation membrane is needed.
