In particular, thermal energy storage (TES) provides several advantages when integrated with nuclear energy. First, nuclear reactors are thermal generators, meaning that fewer energy transformation mechanisms are required when thermal energy is used as the coupling energy resource.
Since heat is a natural product of nuclear reactions, storing the energy produced as thermal energy seems to be an efficient means of storage. Also, storing heat is a technologically simple task so it should be a relatively cheap and reliable energy storage adaptation for nuclear power.
This work is similar to that of Hawwash et al. , in which the reactor design and area ratio were shown to impact the thermal performance and energy storage during the dehydration of a TCES material.

The reactors should be properly insulated to maintain high operating temperature for desired chemical reaction and kinetics and to minimize thermal loss for improved energy conversion efficiency.
Moving bed reactors allow particles to flow in and out with varying mass flow rates and exhibit improved heat transfer and energy storage capabilities compared to fixed bed reactors. However, particle flowability and residence time control to maximize extent of reaction can be challenging.
Finally, in a typical thermochemical reactor system, products and reactants are kept in separate vessels, while the reaction requires continuous monitoring and heat tracing to maintain an ideal operational temperature. Thus, an FOM of 0 was assigned for the turndown and thermal support requirement.
