The paper will present background information on exergy theory; identify the core subsystems in an SMR plant coupled with storage systems in support of renewable energy and hydrogen production; perform a thermodynamic exergy analysis; determine the cost allocation among these subsystems; and calculate unit exergetic costs, unit exergoeconomic costs, and first and second law efficiencies. | Thermodynamic exergy analysis for small modular reactor in nuclear hybrid energy system EPJ Nuclear Sci.

Small modular reactors SMRs provide a unique opportunity for future nuclear development with reduced financial risks allowing the United States to meet growing energy demands through safe reliable clean air electricity generation while reducing greenhouse gas emissions and the reliance on unstable fossil fuel prices. A nuclear power plant is comprised of several complex subsystems which utilize materials from other subsystems and their surroundings. The economic utility of resources or thermoeconomics is extremely difficult to analyze particularly when trying to optimize resources and costs among individual subsystems and determine prices for products. Economics and thermodynamics cannot provide this information individually. Thermoeconomics however provides a method of coupling the quality of energy available based on exergy and the value of this available energy exergetic costs . For an SMR exergy analysis both the physical and economic environments must be considered. The physical environment incorporates the energy raw materials and reference environment where the reference environment refers to natural resources available without limit and without cost such as air input to a boiler. The economic environment includes market influences and prices in addition to installation operation
