| dc.description.abstract-translated | Hybrid energy systems incorporating Small Modular Reactors (SMRs) represent a promising nuclear technology which allows the combined production of heat and power. This increases the f lexibility of nuclear plants and opens new possibilities for the decarbonization of energy production. This thesis explores this concept from both a technical and an economic perspective, proposing and evaluating a conceptual design of the balance of plant for a hybrid light-water SMR. The technical analysis focuses on the design and modeling of the plant interaction with power grid disturbances, particularly for primary frequency regulation. The economic assessment proposes a methodology to estimate the overnight capital cost of LW-SMRs at the preliminary design stage and evaluates the economic competitiveness of hybrid designs compared to full-electrical and full-thermal configurations. The results of the simulations demonstrate the potential of cogeneration plants to mitigate the impact of such transients on the primary loop. Using the heat output to bypass the turbines and modulate electrical power, it is possible to reduce disturbances to the steam generator, the interface between the primary and secondary loops. For the economic assessment, the proposed methodology is applied to open-literature data to estimate the overnight capital costs of electrical, thermal and hybrid SMRs. The reactors are then compared using the Levelized Cost of Electricity (LCOE) and Heat (LCOH), which suggest the potential economic advantages of hybrid SMRs, as LCOE and LCOH calculated are in most cases lower for the hybrid reactors. | en |
