Combination of Thermochemical Energy Storage and Small Pressurized Water Reactor for Cogeneration System

Abstract

In recent decades, small nuclear reactors for cogeneration systems have been studied. Generally, nuclear plants are operated at steady state, but the heat demand load is not steady. Load leveling using thermochemical energy storage (TcES) is a potential method for overcoming this problem. In this work, the heat load of a town was assumed, and the required amount of TcES material for load leveling was estimated. The amount of material required, relative to the volume of the nuclear reactor vessel, was acceptable for installing a TcES system at the nuclear plant.

Profitability Analysis and Capital Cost Estimation of a Thermochemical Energy Storage System Utilizing Fluidized Bed Reactors and the Reaction System MgO/Mg(OH)2

“…A lot of effort has been put into the characterization and improvement of metal oxide/hydroxide systems [14][15][16][17][18][19] as well as the process integration and application of TCES-systems [20][21][22][23][24][25][26]. Also, the reaction kinetics which are important for the precise modelling of reactors [27,28] have been identified for various materials [18,[29][30][31][32].…”
