The editorial advocates for relying on India's indigenous, cost-effective to meet the ambitious target of 100 GW of nuclear power capacity by 2047. It argues against importing expensive foreign technology or untested Small Modular Reactors (SMRs), emphasizing the need to scale up self-reliant capabilities while maintaining a strict safety culture as the sector opens to private players.
The economic viability of nuclear energy in India is central to this discussion. Sanctions post-1974 forced India to develop an indigenous nuclear program, led by the Atomic Energy Commission (AEC). This innovation resulted in highly cost-competitive technology. Indian plants cost approximately $1,700 per Kw, significantly lower than those from South Korea, France, or the US. This price advantage makes Indian nuclear power competitive with thermal power. From a UPSC perspective, this highlights the economic benefits of self-reliance (Atmanirbhar Bharat) in high-tech sectors. The editorial argues against importing expensive foreign technology, noting that it would increase the cost of electricity and create technological vulnerability. The massive scale of India's required expansion (100 GW by 2047) demands a focus on cost-efficiency, which is best achieved by scaling up proven domestic technologies to benefit from economies of scale. Candidates should be prepared to discuss the cost-competitiveness of different energy sources and the implications of opening the nuclear sector to private players under recent legislative changes, which is designed to bring in capital and reduce project execution time.
The technological evolution of India's nuclear program is a key focus. India has progressed from 200 MW units to developing 700 MW units, and recently commissioned a 500 MW commercial fast breeder reactor, showcasing technological leadership. Currently, India relies heavily on Pressurised Heavy Water Reactors (PHWRs) that use natural uranium. However, the global standard often uses Light Water Reactors (LWRs) requiring enriched uranium. The 2008 India-US Civil Nuclear Deal ended restrictions on importing uranium but the Nuclear Suppliers Group (NSG) waiver prohibits transferring enrichment and reprocessing technology. Therefore, the editorial suggests India must develop its own LWR technology. Furthermore, to address the rising power demands of AI data centers, the West is exploring Small Modular Reactors (SMRs). The editorial cautions against deploying untested foreign SMRs in India, advocating instead for the domestic development of smaller units. UPSC mains often tests knowledge on India's three-stage nuclear power program, the differences between PHWRs and LWRs, and the potential and challenges of emerging technologies like SMRs.
The expansion of the nuclear sector brings significant governance and regulatory challenges, particularly concerning safety. The government has set a target of 100 GW by 2047 and has opened the sector to new entrants from the public and private spheres. While necessary for capital infusion and scale, this introduces risks. The editorial emphasizes that a rigorous internal safety culture is paramount. India's exemplary safety record must be maintained, especially given the prevailing industrial culture where accidents occur. A single mishap could cause severe public backlash, similar to the post-Chernobyl disaster reaction, halting progress. Therefore, regulatory bodies like the Atomic Energy Regulatory Board (AERB) face the critical task of ensuring strict compliance and continuous external auditing for new entrants. The governance challenge lies in balancing rapid capacity expansion with stringent safety protocols. Candidates should analyze the regulatory framework governing nuclear safety in India and the socio-political implications of nuclear accidents.
