Here’s a concise summary of **Small Modular Reactors (SMRs)** and the cost comparison study you mentioned:

### **What is a Small Modular Reactor (SMR)?**
– **Definition**: SMRs are advanced nuclear reactors designed to be **smaller (typically <300 MW), modular (built in factories), and scalable** compared to traditional large reactors (1,000+ MW).
– **Key Features**:
– **Modularity**: Components can be prefabricated and assembled on-site, reducing construction time and costs.
– **Flexibility**: Can be deployed in pairs or clusters to meet varying energy demands.
– **Safety**: Often designed with passive safety systems to minimize risks.
– **Applications**: Used for electricity generation, district heating, desalination, or industrial processes.
– **Examples**: NuScale (U.S.), TerraPower (Bill Gates-backed), and Russian designs like RITM-200.

### **Cost Comparison Study**
– A **2023 study** (likely from organizations like the **IAEA, OECD/NEA, or MIT**) found that:
– **SMRs have a higher **levelized cost of energy (LCOE)**—around **3x more expensive per kWh** than large conventional reactors**.
– **Reasons for higher costs**:
– **Economies of scale**: Large reactors benefit from bulk production and lower per-unit costs.
– **Regulatory and licensing hurdles**: SMRs face new safety reviews, delaying deployment.
– **Limited deployment history**: Few commercial SMRs are operational yet (most are in pilot phases).
– **Supply chain challenges**: New manufacturing processes may increase costs.
– **Estimated LCOE**:
– **Large reactors**: ~$50–$100/MWh (varies by region).
– **SMRs**: ~$150–$300/MWh (depending on design and scale).

### **Why Pursue SMRs Despite Higher Costs?**
1. **Flexibility**: Can be deployed in remote areas or paired with renewables for grid stability.
2. **Safety & Public Acceptance**: Smaller size may reduce public opposition compared to large plants.
3. **Future Potential**: Costs could drop with mass production (like solar/wind initially).
4. **Decarbonization**: Provide **carbon-free baseload power**, complementing intermittent renewables.
5. **Export Opportunities**: Modular designs are easier to transport and deploy globally.

### **Current Status (as of 2026)**
– **Few commercial SMRs are operational** (most are in advanced testing phases).
– **Government support**: Many countries (U.S., UK, Canada, China) are investing in SMR R&D to accelerate deployment.
– **Challenges**: High upfront costs, regulatory delays, and competition from renewables + storage.

### **Key Takeaways**
– **SMRs are not yet cost-competitive** with large reactors or renewables in most markets.
– **Long-term viability depends on**:
