Small Modular Nuclear Reactors, Hydrogen Economy, Cost Analysis, Energy Transitions

Resumen

Hydrogen is an important energy vector for the global energy transition. Due to its low carbon emissions, it has become a central subject of study for major nations. Small modular nuclear reactors (SMRs) represent an innovative approach in the nuclear field. This technology provides greater versatility, safety, and lower costs for energy production on a reduced scale compared with large nuclear reactors (LRs). This paper presents an economic evaluation of hydrogen production using a Small Modular Nuclear Reactor (SMR) as the primary energy source. The methodology uses the Hydrogen Economic Evaluation Programme (HEEP) software provided by the International Atomic Energy Agency (IAEA) to estimate the levelized cost of hydrogen production (LCOH, in USD/kg of H2) using SMRs. The model considers intrinsic characteristics of the power generation plant and of the Polymer Electrolyte Membrane (PEM) plant, the latter supplied by Hytron/NEA. To validate the methodology, it was necessary to evaluate the hydrogen production costs for a large reactor on the market, the AP1000 from Westinghouse. Based on these results, a 77 MWe NuScale SMR built under the same inflationary conditions as the LR was evaluated to avoid significant distortions in the results. For a realistic evaluation, cost studies provided by international institutions such as MIT and the U.S. Department of Energy`s Nuclear Energy Administration (DOE/NEA), and, when possible, by NuScale and Westinghouse, the companies responsible for the reactors being analyzed, were used. Preliminary results show that SMRs present significant competitiveness in terms of levelized cost of hydrogen compared to alternative clean energy sources such as renewable, including solar photovoltaic, solar thermal, and wind power. Due to the versatile, scalable, continuous, predictable, and dispatchable generation profile of SMRs, the cost difference found is negligible. This validates the potential of nuclear technology, which plays a strategic role in the energy transition both globally and in Brazil, and reinforces the importance of in-depth assessments on the subject.

    I research the economic evaluations of using nuclear power units for the production of low-carbon hydrogen. Additionally, I am involved in CFD simulations to estimate the efficiency and bubble behavior of electrolyzers in green hydrogen production. I have a strong interest in artificial intelligence and have developed a fully functioning artificial neural network from scratch, utilizing only standard programming without any specialized libraries. Currently, I am seeking to deepen my understanding of the behavior of multi-layer perceptrons (MLPs) and deep learning algorithms. I also have experience in predicting material defects, having developed an algorithm capable of monitoring the health of concrete bridge components and determining how frequently they require maintenance by the responsible organizations. Furthermore, I am conducting research on experimental membraneless electrolysis for hydrogen production as part of the PRH-48.1 program.

    Master's (2019) and PhD (2023) in Energy and Nuclear Technologies from the Federal University of Pernambuco (UFPE). He has a degree in Chemical Engineering from Centro Universitário Maurício de Nassau (2017). As a master's and doctoral student, he developed and implemented thermohydraulic models using computational fluid dynamics (CFD) to evaluate the operating conditions of the AP1000 reactor using a mixture of uranium and thorium oxides as nuclear fuel. He also developed codes in MATLAB for coupling between SERPENT (reactor physics) and ANSYS CFX / ANSYS FLUENT (reactor engineering) codes. He is currently a postdoctoral researcher and works as a CFD engineer in thermal and hydraulic analyses using the ANSYS CFX and ANSYS FLUENT tools to ensure the safe operation of new nuclear reactor proposals foreseen in the National Energy Plan (PNE) strategies on the horizon 2030 and 2050. He is also part of the team of experts for the CNPQ universal project: "Implementation of new experimental techniques for 3D analysis of thermohydraulic phenomena in investigations of SMR type reactors".
