Small Modular Reactor Industry Segmentation:

IMARC Group provides an analysis of the key trends in each segment of the global small modular reactor market report, along with forecasts at the global, regional and country levels from 2025-2033. Our report has categorized the market based on reactor type, deployment, and application.

Breakup by Reactor Type:

• Heavy Water Reactor (HWR)
• Light Water Reactor (LWR)
• Fast Neutron Reactor (FNR)
• Others
   

Heavy water reactor (HWR) dominates the market

The report has provided a detailed breakup and analysis of the market based on reactor type. This includes heavy water reactor (HWR), light water reactor (LWR), fast neutron reactor (FNR), and others. According to the report, heavy water reactor represented the largest segment.

Heavy Water Reactor (HWR) uses heavy water (deuterium oxide) as a neutron moderator, enabling them to sustain a nuclear chain reaction efficiently. These reactors are known for their high neutron economy, making them suitable for using natural uranium as fuel, which reduces the need for uranium enrichment.

Furthermore, the Light Water Reactor (LWR), the most prevalent type of nuclear reactor globally, uses ordinary water as both a coolant and a moderator. Pressurized Water Reactors (PWRs) and Boiling Water Reactors (BWRs) are two common subtypes. LWRs are known for their safety and reliability, providing a stable and cost-effective power generation option.

Moreover, Fast Neutron Reactor (FNR) utilizes fast neutrons to sustain a chain reaction. Unlike LWRs and HWRs, they do not require a moderator. Fast reactors can convert fertile material like depleted uranium and thorium into fissile fuel, enhancing resource utilization and reducing nuclear waste. Though still in the development stages, FNRs show promise for their potential to contribute to long-term sustainability and radioactive waste reduction.
