The lack of plant-side energy storage analysis to support nuclear power plants (NPP), has setup thisresearch endeavor to understand the characteristics and role of specific storage technologies and theintegration to an NPP. The paper provides a qualitative review of a wide range of configurations forintegrating the energy storage system (ESS) to an operating NPP with pressurized water reactor (PWR). The role of ESS technologies most suitable for large-scale storage are evaluated, including thermal energystorage, compressed gas energy storage, and liquid air energy storage. The methods of integration to theNPP steam cycle are introduced and categorized as electrical, mechanical, and thermal, with a review ondevelopments in the integration of ESS with an operating PWR. By adopting simplified off-designmodeling for the steam turbines and heat exchangers, the results show the performance of the PWRsteam cycle changes with respect to steam bypass rate for thermal and mechanical storage integrationoptions. Analysis of the integrated system characteristics of proposed concepts for three different ESSsuggests that certain storage technologies could support steady operation of an NPP. After havingreviewed what have been accomplished through the years, the research team presents a list of possiblefuture works. KCI Citation Count: 0
