What is the role of nuclear power in clean energy transitions? Nuclear power accounts for about 10% of electricity generation globally, rising to almost 20% in advanced economies. It has historically been one of the largest global contributors of carbon-free electricity and while it faces challenges in some countries, it has significant potential to contribute to

The nuclear reactor will operate at a constant power level, supplying heat to the thermal energy storage (TES) block. The TES block will provide heat as needed to the electric generation subsystem, which can be designed to rapidly respond to changes in electric power demand [1].
The electric boilers consume the excess power of nuclear power units during the valley period of the power grid. The heat generated by the electric boilers is stored in the heat storage tank to supply the consumers'' demands.
By harnessing the energy released during nuclear reactions, power plants produce the electricity that fuels industries, cities, and futuristic infrastructure. However, with ageing grid infrastructures and evolving energy needs, the integration of energy storage systems has become crucial.
Nuclear and solar thermal systems produce heat; thus, thermal energy storage is a preferred form of energy storage because it avoids the inefficiencies in conversion from one storage media to another.
This study reviews TES options in the context of enabling a flexible CHP supply while maintaining a steady nuclear heat input. Heat storage systems that interface between the reactor primary fluid and the CHP system offer superior performance and flexibility.
This work looks at a few energy storage technologies suitable for large-scale electricity storage from base-load power plants such as nuclear power plants. A preliminary assessment of these technologies has been completed through a literature review.
In the present scenario, the integration of thermal energy storage systems (TES) with nuclear reactors holds the potential to enhance the uninterrupted and efficient functioning of nuclear power plants.
Recently, thermal energy storage system (TES) has been studied for nuclear power plant (NPP) application in several previous studies [3-5]. TES is easy to integrate with NPP because both direct heating and electrical heating are possible.
A ternary-Pumped Thermal Electricity Storage (t-PTES) system integrates a heat pump, a thermal energy storage tank system, and a heat engine with a grid-connected nuclear power plant, as can be seen in Figure 1.
This is essential to accommodate the fluctuating output of renewable sources while ensuring the security of the energy supply. In the present scenario, the integration of thermal energy storage systems (TES) with nuclear reactors holds the potential to enhance the uninterrupted and efficient functioning of nuclear power plants.
The electric boilers consume the excess power of nuclear power units during the valley period of the power grid. The heat generated by the electric boilers is stored in the heat storage tank to supply the consumers’ demands. Fig. 1. Model of the nuclear power plant with EHS. 2.2. Modeling of NPP with EHS 2.2.1.
Integrated ESS nuclear power plant yields a higher capacity factor. Various forms of energy storage systems are currently under development, including mechanical energy storage (MES) systems, thermal energy storage (TES) systems, electric energy storage (EES) systems, and chemical energy storage (CES) systems .

A viable approach involves combining thermal energy storage with nuclear power plants. Because of this, the reactor's output could be kept at a practically constant level while the electrical generator's output can be varied in response to the changing demands of the net load . 2.3. Types of TES systems
In this paper, the proposed model solves the problem of the limited range of power changes and peak-shaving depth of nuclear power plants. The proposed operation strategy of the nuclear power plant with electric heat storage not only enhances the heating and electric profits but also reduces the cost-sharing fee of the nuclear power plant.
