Context: Nearly 20 years after the India-US civil nuclear deal was signed, Holtec International, a privately-held US company, has emerged as a potential catalyst to finally unlock the commercial potential of the pact.
About Small Modular Reactors (SMRs):
- Definition: Advanced nuclear reactors with a power capacity of up to 300 MW per unit, about one-third the size of traditional reactors.
- Features:
- Small: Compact size, making them versatile for different sites.
- Modular: Can be factory-assembled and transported for on-site installation.
- Reactors: Use nuclear fission to generate heat and produce energy.
Advantages
- Longevity: Designed to operate for 40-60 years with over 90% capacity factors.
- Low-Carbon Electricity: Efficient in generating large amounts of clean energy.
- Flexibility: Ideal for remote locations and can be paired with renewable energy in hybrid systems.
- Cost Efficiency: Reduced fuel needs, lower staffing, and off-site manufacturing save construction time and costs.
- Repurposing Sites: Can be installed on decommissioned thermal power plant sites using existing infrastructure.
Safety Features
- Enhanced Safety: Smaller core damage risk, improved seismic isolation, and passive safety features reduce potential radioactive leaks.
- Simple Design: Lower likelihood of uncontrolled radioactive releases compared to traditional reactors.
Disadvantages
- Limited Availability: Not yet widely used for power generation.
- Economic Viability: Requires large-scale production to be cost-effective.
- Regulatory Challenges: Licensing for SMRs is complex and costly, designed primarily for larger reactors.
