The small modular reactor market is expected to experience growth driven by the escalating energy security crisis. An energy security crisis arises when a region or country encounters substantial challenges in reliably and affordably meeting its energy needs. Small modular reactors (SMRs) present a solution by offering flexibility in power output, enabling operators to swiftly adjust electricity generation to meet the specific requirements of remote communities or industries. They can operate at partial load or ramp up or down quickly in response to changing demand, ensuring a stable and reliable power supply. Data from the International Energy Agency (IEA) in November 2022 indicates a projected increase in the global population lacking access to electricity, reaching approximately 774 million individuals in 2022, up from 754 million in 2021. Consequently, the growing energy security crisis is a key driver behind the growth of the small modular reactor market.

Leading companies in the small modular reactor market are intensifying their efforts to develop advanced solutions or products, such as single-loop pressurized water reactors (PWR), to maintain a competitive edge. Single-loop PWR is a compact and scalable nuclear reactor design ranging from tens to a few hundred megawatts, offering improved safety features, deployment flexibility, and potential cost-effectiveness compared to traditional larger-scale nuclear power plants. In May 2023, Westinghouse Electric Company, a US-based nuclear power company, introduced the AP300. This small modular reactor incorporates integral pressurized water reactor (iPWR) technology, passive safety systems, and modular design, revolutionizing nuclear energy with compactness, enhanced safety, and rapid deployment. The AP300 significantly impacts the small modular reactor (SMR) market by advancing safety, versatility, and cost-effectiveness, shaping the future of nuclear energy generation.

In November 2023, Cameco Corporation, a Canada-based uranium company, partnered with Brookfield Asset Management (BAM) to acquire Westinghouse Electric Company for $8.2 billion. This strategic move strengthens their positions in the nuclear industry and underscores a commitment to advancing innovative solutions, including Westinghouse's eVinci micro-reactor technology. The acquisition reflects a collaborative effort to meet the rising demand for clean and reliable energy sources. Westinghouse Electric Company is a US-based nuclear power company that offers nuclear products and services, including small modular reactors (SMR).

A small modular reactor (SMR) is a compact nuclear reactor design known for its smaller size, simplified construction, and modular configuration tailored for electricity generation. These reactors are utilized to provide scalable and flexible nuclear power solutions suitable for a range of applications, including remote locations, industrial processes, and grid supplementation.

The primary types of small modular reactors include light water reactors (LWR), fast neutron reactors (FNR), heavy water reactors (HWR), and others. Light water reactors (LWR) use regular water as both the coolant and neutron moderator, and they are widely employed in commercial nuclear power plants due to their efficient operation and relative safety. The power rating categories for these reactors include up to 100 MW, 101 to 200 MW, and 201 to 300 MW. These reactors are deployed in single-module power plants and multi-module power plants, serving various applications such as power generation, desalination, process heat, industrial use, and hydrogen production.
