Abstract
A nuclear power plant is one of the power sources that shares a large portion of base-load. However, as the proportion of renewable energy increases, nuclear power plants will be required to generate power more flexibly due to the intermittency of the renewable energy sources. This paper reviews a layout thermally integrating the liquid air energy storage system with a nuclear power plant. To evaluate the performance realistically while optimizing the layout, operating nuclear power plant conditions are used. After revisiting the analysis, the optimized performance of the proposed system is predicted to achieve 59.96% of the round-trip efficiency. However, it is further shown that external environmental conditions could deteriorate the performance. For the design of liquid air energy storage-nuclear power plant integrated systems, both the steam properties of the linked plants and external factors should be considered.

Summary
Integrated to Nuclear Steam Cycle.The concerns around global warming and environmental issues are growing, and the development of eco-friendly renewable energies plays an important role as a solution [1,2,3]. Renewable energy sources such as solar and wind, unlike conventional power generation systems, cannot produce electricity consistently and follow the demand. It means that renewable power sources cannot generate extra energy or reduce output power due to sudden changes in demand [4]. They should, have an energy storage system that can store a large amount of energy and discharge when needed. ESS can smooth out the sharp output from renewable power sources that could damage the electricity grid [5,6,7]
