Review on Optimization of Nuclear Power Development: A Cyber-Physical-Social System in Energy Perspective

Nuclear power development is a complex issue spanning cyber, physical, and social systems that is essential to achieving energy security and climate goals. With the ongoing worldwide trend towards carbon neutrality, the positioning of nuclear power in energy mix should be reconsidered. This paper aims to present a systematic review of current research on optimization of nuclear power development. The concept of cyber – physical – social system in energy (CPSSE) is adopted, which provides a suitable perspective and enables the review of relevant studies to achieve some novel insights. Based on the CPSSE, firstly, a research framework is established and the main research elements in optimization are identified, followed by a proposed conceptual risk-based optimization model. Secondly, current studies are analyzed and classified into four categories according to the research boundary. The status quo and limitations are discussed. It is found that the research results of nuclear-specific issues have not been well integrated into the optimization of nuclear power. As a relatively reliable power supply, nuclear power is capable of maintaining power and electricity adequacy of the whole system, especially in the case of power shortage caused by long-period low output of renewable energy or extreme external disasters. This superiority should not be ignored in the optimization. Other critical factors that should be further considered include disruptive technologies, nuclear safety, energy policies, and stakeholder behaviors. Finally, suggestions are given for future research.
