Abstract
Nuclear reactors are commonly subject to significant variable energy demands. These variable energy requirements can negatively affect the effective capacity factor of the reactor and result in severe penalties with the waste and inefficient use of fissile fuel. Coupling a nuclear reactor to a thermal energy storage system can enable the use of nuclear energy in power and propulsion systems more reasonably. The nuclear reactor can operate at a constant power level, supplying heat to the TES (Thermal Energy Storage), which can supply the power system, as required, rapidly responding to variations in demand without overloading the control system. Nonetheless, the linkage results not only increased the safety of the energy conversion system but also implies that less nuclear fuel is used, resulting in more compact nuclear reactors. Thus, this study aims to understand high-temperature latent heat storage systems with nanoparticles during the melting processes, in order to ensure the compactness and safety of a reactor. The study will be carried out through the use of computational tools such as computational fluid mechanics (CFD), applied to a known TES available in the open literature.
