Thermalhydraulic analysis and heat transfer correlation for an intermediate heat exchanger linking a SuperCritical Water-cooled Reactor and a Copper-Chlorine cycle for hydrogen co-generation

Hydrogen Production from Nuclear Energy

“…8.3 Flow configuration for high-temperature and low-temperature IHX systems: (a) coreside configuration; (b) shell-side configuration Another type of IHX is for linkage of a supercritical water-cooled reactor (SCWR) to a thermochemical water-splitting plant. Mokry et al (2012) have developed a conceptual design of a heat exchanger that uses supercritical water in the primary circuit and generates superheated steam at the secondary circuit. The design is based on experimental data which was correlated by the Buckingham Π theorem.…”

“…The Mokry et al (2012) correlation for the supercritical side of the heat exchanger with forced convection flow is described by Nu ¼ 0:0061 Re 0:904 Pr 0:684 ðρ w =ρÞ 0:564 ;…”

Safety Analysis of the Hydrolysis Reactor in the Cu-Cl Thermochemical Hydrogen Production Cycle—Part 1: Methodology and Selected Top Events

“…To fully realize a global hydrogen economy, a vast amount of hydrogen production is needed to produce hydrogen that can be efficiently and economically produced at a large scale. Thermochemical hydrogen production has the potential to provide cheap and abundant hydrogen using thermal energy sources, such as industrial waste heat or nuclear energy [1][2][3][4]. Simulations by Rosen et al predicted that a copper-chlorine-based thermochemical cycle could achieve efficiencies of 52% when paired with a generation IV super-critical water-cooled reactor (SCWR) [5].…”

“…Economically, Wu found that labor cost was the dominating factor in operating costs [6]. Due to its low operating temperatures and thermal efficiency, the copper-chlorine thermochemical hydrogen production is well suited to operate in a co-generation installation, often with other thermal power systems or refrigeration cycles [3,[7][8][9].…”
