This study conducts a heat transfer analysis on a three-phase oxygen reactor equipped with a spiral baffled jacket, assessing the number of reactors needed to achieve various hydrogen production rates through enough heat input. It explores the efficiency of helium gas and molten CuCl in transferring heat from the jacket to the process side of the reactor. Considering a nuclear reactor as the primary heat source for the Cu-Cl cycle, the analysis focuses on two nuclear reactor types: the CANDU Super Critical Water Reactor (CANDU-SCWR) and the High Temperature Gas Reactor (HTGR). Findings indicate that the major thermal resistance in the jacketed oxygen reactor system stems from the reactor wall, contributing approximately 80% to the total thermal resistance due to conduction. The study suggests that the SCWR requires a higher heat transfer rate compared to the HTGR. In terms of fluid choice for the jacket's service side, helium gas is recommended over molten CuCl for better heating efficiency. Furthermore, the analysis concludes that determining the oxygen reactor's size should be based on heat balance calculations, rather than material balance considerations.

In this paper, the heat transfer analysis of the three-phase oxygen reactor with a spiral baffled jacketed reactor are performed. The required number of oxygen reactors is analysed to provide enough heat input for different hydrogen production rates. Two types of fluids, which are helium gas and molten CuCl, are investigated to transfer heat from the jacket side to the process side of the oxygen reactor. In the analysis, the Cu-Cl cycle is assumed to be driven by a nuclear reactor where two types of nuclear reactors are examined as the heat source to the oxygen reactor. These types are the CANDU Super Critical Water Reactor (CANDU-SCWR) and High Temperature Gas Reactor (HTGR). In this paper, it was found that the dominant contribution to the thermal resistance of the jacketed oxygen reactor system was from the reactor wall, where heat transfer occurred by conduction only. This contribution is about 80% of the total thermal resistance. It was also shown that a better heat transfer rate is required for SCWR than that for HTGR. Moreover, from the study of the fluid types that can be used in the service side, it was recommended to use helium gas instead of molten CuCl as a heating fluid in the jacket. Finally, it was found that the size of the oxygen reactor must be specified from the heat balance studies rather than material balance.

In order to glean some insight into the likely trends in the next 50 years of power generation, the major trends of the last 50 years are reviewed first of all. It is noted that not only were all the power generating systems in operation today being researched in the 1960s, but so were most of those now being discussed for the future. The major trends in generation have all been driven by political and environmental considerations rather than by radically new ideas.For the next 50 years, in a new environment of concern about climate change and security of electricity supply, new technology must be developed to make some more of the options economically viable. This article surveys most of the systems now being considered and picks out a few of the enabling technologies. With such a broad subject, selectivity in the choice of sources is inevitable: this review draws preferentially upon papers published in the Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy over the last 10 years.
