On the Thermal Integration of Nuclear Heat in a Solar Thermal Plant for Continuous Thermochemical Processes
Abstract
High-temperature thermochemical processes enable the generation of non-fossil fuels such as hydrogen, syngas, biobased crude oil, and coal. These processes take place inside a reactor where different species are mixed and react depending on the product to be obtained. To promote chemical reactions, high temperature and pressure levels are required inside the reactor. Nuclear energy is an interesting source of heat for continuous thermochemical processes. Innovative generation IV reactors have safety and reliability features, which enable them to ensure the sustainable use of nuclear energy. Currently, nuclear heat is used to convert heat into work in power generation systems using Rankine and Brayton cycles, and to produce hydrogen by water splitting. This paper analyzes the challenges facing nuclear energy as a backup heat source for industrial processes, particularly in solar hydrothermal processes.
