Model Answer
Key Challenges in Expanding Nuclear Energy in India
India faces several significant challenges in expanding its nuclear energy infrastructure to meet its net-zero emission targets. These include issues related to resource dependency, investment barriers, and social concerns.
1. Import Dependency
India’s nuclear energy infrastructure is heavily reliant on imports for uranium, which raises sustainability concerns. Between 2019-2022, India imported over 7,600 tonnes of uranium, primarily from Kazakhstan and Canada. This import dependency makes the long-term sustainability of nuclear energy uncertain and exposes the country to global supply chain disruptions. Investment Barriers The high capital cost of building nuclear power plants, along with prolonged profitability horizons, presents a significant investment challenge. Nuclear projects are capital-intensive and have long lead times, often extending beyond a decade. Licensing and regulatory hurdles further delay project timelines, deterring both domestic and foreign investment .
2. Energy
Nuclear energy is more expensive compared to other renewable sources. The levelized cost of energy (LCOE) from solar and wind energy stands at approximately $40 per megawatt-hour, while nuclear plants average around $175 per megawatt-hour. This cost disparity makes nuclear energy less competitive, especially as India pushes for more affordable and sustainable energy sources .
3. Wast
The disposal and storage of nuclear waste remain a major concern. Nuclear waste remains hazardous for long periods, requiring secure storage solutions. India currently lacks a comprehensive and long-term plan for managing nuclear waste, which complicates the expansion of nuclear energy .
4. Land Acquisitcal Opposition
Acquiring land for new nuclear power plants is a complex process, often hampered by legal challenges, local opposition, and competing land uses. For example, the proposed installation of six French reactors in Maharashtra has faced delays due to land acquisition difficulties and local protests .
5. Water Scarcity
Nuclelants require significant amounts of water for cooling reactors. As many rivers and water bodies are facing depletion, the availability of reliable water sources for these plants is becoming increasingly uncertain .
To meet its net-zero goals, India must ade challenges by enhancing its resource security, investing in technological innovations for waste management, and fostering public and investor support for nuclear energy expansion.
