India's ambitious plans for Small Modular Reactors (SMRs) face significant viability challenges, primarily due to high upfront costs, the absence of a robust domestic supply chain, and complex regulatory frameworks. While the Department of Atomic Energy (DAE) aims to develop SMRs for clean energy transition and industrial applications, experts caution that commercial orders and a dedicated supplier ecosystem are crucial for their success.
SMRs, with their smaller footprint and modular design, offer potential benefits like faster deployment and enhanced safety, but their economic competitiveness against conventional large reactors and other energy sources remains a key concern. Private sector participation is deemed essential to overcome these hurdles and scale up SMR deployment.

India's Clean Energy Ambition: Context for SMRs (as of Dec 2025)
This dashboard highlights India's key clean energy targets and current progress, providing context for the Department of Atomic Energy's (DAE) ambition to deploy Small Modular Reactors (SMRs) as part of the broader clean energy transition.
- India's Net Zero Target
- 2070
- Non-Fossil Fuel Capacity Target
- 50% by 2030
- Current Non-Fossil Fuel Capacity Share
- ~45%
India's long-term commitment to decarbonization, announced at COP26, drives investments in all clean energy technologies, including nuclear power like SMRs.
An intermediate target to significantly reduce the carbon footprint of India's electricity generation. SMRs are seen as a stable, low-carbon baseload option to achieve this.
As of December 2025, India has made significant progress towards its 2030 target, primarily driven by rapid renewable energy expansion. SMRs can further diversify this mix.

बहुविकल्पीय प्रश्न (MCQ)
1. Consider the following statements regarding Small Modular Reactors (SMRs) in India: 1. SMRs are characterized by their smaller power output, modular design, and potential for factory fabrication. 2. The Department of Atomic Energy (DAE) aims to develop SMRs primarily for industrial applications and remote area power supply. 3. A key challenge for SMR deployment in India is the lack of a robust domestic supply chain and high upfront costs. Which of the statements given above is/are correct?
उत्तर देखें
सही उत्तर: D
Statement 1 correctly defines SMR characteristics, highlighting their key design principles. Statement 2 aligns with the DAE's stated goals for SMRs, emphasizing their utility beyond just grid-scale electricity generation. Statement 3 directly reflects the viability challenges mentioned in the news article, which are critical for their successful deployment. All three statements are accurate in the context of SMRs and India's ambition.
2. With reference to India's nuclear power program, consider the following statements: 1. India's three-stage nuclear power program aims to utilize the country's vast thorium reserves. 2. Pressurized Heavy Water Reactors (PHWRs) form the backbone of the first stage of India's nuclear power program. 3. The Atomic Energy Regulatory Board (AERB) is responsible for the development and promotion of nuclear energy in India. Which of the statements given above is/are correct?
उत्तर देखें
सही उत्तर: A
Statement 1 is correct; the 3-stage program is a long-term strategy designed to move from natural uranium to plutonium, and eventually to fully utilize India's vast thorium reserves. Statement 2 is correct; PHWRs, which use natural uranium as fuel and heavy water as moderator and coolant, are the workhorse of the first stage of India's nuclear power program. Statement 3 is incorrect; the AERB is the independent regulatory body responsible for ensuring nuclear safety and radiation protection. The Department of Atomic Energy (DAE) is responsible for the development and promotion of nuclear energy in India.
3. In the context of India's clean energy transition, the viability challenges for Small Modular Reactors (SMRs) are often compared with other energy sources. Which of the following statements correctly highlights a key economic concern for SMRs?
उत्तर देखें
सही उत्तर: B
The news article explicitly mentions 'economic competitiveness against conventional large reactors' as a key concern for SMRs. While SMRs offer benefits like faster deployment due to modularity (making C incorrect) and enhanced safety, their current capital cost per unit of power is often higher than large reactors. This is primarily due to the lack of economies of scale in initial deployments and the nascent stage of their commercialization (B is correct). Operational costs might be comparable or even higher initially due to specialized maintenance (A is incorrect). The fuel cycle for most SMR designs is generally similar to conventional light water reactors, not entirely different, so D is incorrect.
