“…Based on the preference orders and the weights calculated, nuclear is rated in the last place, except for its future role (Table 3). Although nuclear offers economic benefits during the operating period [67,68], its accidents and catastrophes [15] have an impact on social acceptance of this technology. The acceptability of the risk of nuclear energy and the effectiveness of nuclear waste disposal have long been questionable (see [69]).…”

Renewable and nuclear power technologies are considered alternatives to fossil-based power. However, which of the two is superior remains a matter of contention. Besides technological development, local access to resources, and energy policies, social acceptance is a key issue; informing future decisions on energy sources thus requires a complex approach. Personal attitudes to energy technologies may differ from professional opinions and national policies. The purpose of this study is to explore the attitudes and opinions regarding renewable and nuclear power generation technologies by pairwise comparison. This evaluation includes the return on the investment, the availability of said technologies, environmental impact, knowledge/need of use, and expectations for future of energy production. The research sample consists of 250 randomly selected Hungarian higher education students as representatives of future corporate decision-makers. The results show that the respondents demonstrate an appreciation of renewable energy technologies. Solar energy is appreciated, but confidence in nuclear power is low, except for its future role. These opinions are not consistent with the national energy policies or professional evaluations. These differences will allow us to refine communication and education in the field.

“…The need for extensive integration with the grid or Some renewable energies resources (e.g., nuclear energy and virtually carbon-free energy sources) have emerged as promising solutions for ecological degradation and energy security problems. Many countries have started investing in nuclear and renewable energies to reduce over-dependency on the crude oil trade, stemming from the desires for sustainable energy [6]. Based on the data from Figure 1, conventional energy sources (petroleum and liquids, coal and natural gas) are still forecast to account for about 78% of the global energy consumption in 2040.…”

The strong demand for sustainable energy supplies had escalated the discovery, and intensive research into cleaner energy sources, as well as efficient energy management practices. In the context of the circular economy, the efforts target not only the optimisation of resource utilisation at various stages, but the products’ eco-design is also emphasized to extend their life spans. Based on the concept of comprehensive circular integration, this review discusses the roles of Process Integration approaches, renewable energy sources utilisation and design modifications in addressing the process of energy and exergy efficiency improvement. The primary focus is to enhance the economic and environmental performance through process analysis, modelling and optimisation. The paper is categorised into sections to show the contribution of each aspect clearly, namely: (a) Design and numerical study for innovative energy-efficient technologies; (b) Process Integration—heat and power; (c) Process energy efficiency or emissions analysis; (d) Optimisation of renewable energy resources supply chain. Each section is assessed based on the latest contribution of this journal’s Special Issue from the 21st conference on Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction (PRES 2018). The key results are highlighted and summarised within the broader context of the state of the art development.

“…Integrating nuclear energy with renewable energy resources has also been investigated in the literature. Suman recently reviewed hybrid nuclear‐renewable energy systems resulting in that integrating nuclear energy and renewable energy into a single hybrid energy system could manage to overcome the deficiencies available when they operate individual. Kim et al analyzed a high‐temperature steam electrolysis plant integrated into a light water reactor in nuclear‐renewable hybrid energy systems.…”

In this study, authors present a new hybrid nuclear small modular reactor system assisted with wind energy for net zero emissions trigeneration system. Small modular reactors bring multiple advantages including (a) improved thermal efficiency, (b) better building efficiency due to modularity, and (c) less operation and maintenance costs compared to standard nuclear power generation. Furthermore, the greenhouse gas emissions from small modular reactors are lower than regular counterparts. This study hybridizes small modular reactors with wind turbines for producing three useful commodities, namely electricity, hydrogen, and hot water. A two‐step high‐temperature thermochemical cycle (based on hydrogen chloride gas) is used for hydrogen production, and its performance in terms of energy and exergy efficiencies is evaluated. Additionally, the exergy and energy analyses (by writing balance equations for each component of the system) are carried out to determine the thermodynamic feasibility of the proposed system. In order to observe the effects of various parameters such as the temperature of the thermochemical cycle steps, inlet gas turbine temperature, the pressure ratio of the gas turbine, actual wind speed, and current density on the system performance, a detailed parametric study is conducted. The results of this study show that the overall system can achieve an energy efficiency of about 57.5% and exergy efficiency of about 38.1%.
