It can complement solar and wind energy by providing firm, round-the-clock electricity, supporting India&#8217;s climate commitments and net-zero target.<\/li>\n<li><strong>Limitations attached with other renewable energy sources: <\/strong>Solar energy is land intensive, wind energy requires energy storage systems. Also, they require imported technologies and materials such as photovoltaic cells, batteries, and storage equipment. On the other hand, indigenous nuclear reactors have reduced dependency in critical imports.<\/li>\n<li><strong>Cheaper to Operate: <\/strong>Nuclear power plants are cheaper to operate than coal or gas plants, despite the cost of managing radioactive fuel and disposal. According to estimates, nuclear plants cost only 33-50% of a coal plant and 20-25% of a gas combined-cycle plant.<\/li>\n<li><strong>Ensures Reliable Base-Load Power:<\/strong> Nuclear power plants can operate continuously for extended periods, irrespective of weather conditions. They can help meet India&#8217;s growing electricity demand and complement the variable output of renewable energy sources.<\/li>\n<li><strong>Utilisation of Abundant Thorium Reserves:<\/strong> India possesses significant thorium resources, particularly in monazite-bearing beach sands. The 3-stage programme aims to convert thorium-232 into fissile uranium-233, creating a potential long-term domestic nuclear fuel resource.<\/li>\n<li><strong>Strengthens Technological Self-Reliance<\/strong>: Indigenous development of Pressurised Heavy Water Reactors (PHWRs), fast breeder reactors and advanced nuclear technologies strengthens India&#8217;s capabilities in <span class=\"w6asjq_TextBase _85PZeG_Text\" data-d-component=\"text\" data-d-default-strong=\"\" data-d-inline=\"\">reactor design, fuel fabrication, reprocessing and nuclear engineering.<\/span><\/li>\n<li><strong>Supports Industrial and Economic Development<\/strong>: The nuclear programme stimulates demand for high-precision manufacturing, heavy engineering, specialised materials, electronics and scientific instrumentation. It can generate skilled employment and strengthen India&#8217;s advanced manufacturing ecosystem.<\/li>\n<li><strong>Promotes Strategic Autonomy<\/strong>: Domestic nuclear capabilities reduce vulnerability to external technology restrictions and fuel-supply disruptions. They also strengthen India&#8217;s strategic autonomy in a sector closely linked to national security and critical infrastructure.<\/li>\n<\/ol>\n<h2 class=\"blue-h2-box\"><span style=\"color: #000000;\"><strong><a id=\"toc4\"><\/a><span style=\"text-decoration: underline;\">What are the challenges to India&#8217;s Nuclear Energy Programme?<\/span><\/strong><\/span><\/h2>\n<ol>\n<li><strong>High capital cost and financing constraints:<\/strong> Nuclear power plants require massive upfront investment, long construction periods and extended payback timelines.. There have been cost over runs in recently built nuclear power plants.<\/li>\n<li><strong>Delays in project execution<\/strong>: Nuclear projects often face delays due to complex engineering, regulatory clearances, equipment procurement and commissioning requirements. The long gestation period can escalate costs and postpone electricity generation.<\/li>\n<li><strong>Insufficient Installed Capacity: <\/strong>As of 2025-26, India\u2019s installed nuclear power capacity is about 8,780 MW across 24 reactors, against a target of 100 GW by 2047 under the Nuclear Energy Mission.<\/li>\n<li><strong>Nuclear Safety:<\/strong>\u00a0Local communities in India have been resisting nuclear reactors due to fears of nuclear disasters like Chernobyl, 1986 or Fukushima, 2011.<strong> For e.g.<\/strong>\u00a0Locals protesting against the Mithi virdi nuclear project in Gujarat.<\/li>\n<li><strong>Nuclear Liability Concerns:<\/strong> <span style=\"color: #ff0000;\"><span style=\"color: #000000;\">Civil Liability for Nuclear Damage Act, 2010 had been a long-standing deterrent to foreign suppliers due to unlimited supplier liability. The SHANTI Act, 2025 now replaces it with a graded, capped liability framework &#8211; removing automatic supplier liability and introducing tiered operator caps based on reactor size. However, opposition parties have raised concerns about dilution of supplier accountability.<\/span><\/span><\/li>\n<li><span class=\"w6asjq_TextBase _85PZeG_Text\" data-d-component=\"text\" data-d-default-strong=\"\" data-d-inline=\"\"><strong>Limited private sector participation<\/strong>:<\/span> The Atomic Energy Act, 1962, historically reserved nuclear power generation primarily for government entities, restricting private sector involvement. However, recent reforms have begun to enable greater, albeit limited, private participation in the sector.<\/li>\n<li><strong>Hurdles created by NSG and NPT: <\/strong>India&#8217;s non-ratification of NPT and lack of NSG membership, has created diplomatic hurdles in accessing more nuclear fuel and better nuclear technologies.<\/li>\n<li><strong>Use of outdated technology: <\/strong>Currently operational Indian nuclear reactors have become outdated and suffer from multiple operational problems. <strong>For e.g.<\/strong>\u00a06 VVER (water-water energy reactor) design reactors encountering operational problems at Kudankulam.<\/li>\n<li><strong>Dependence on imported technology and components<\/strong>: Despite significant indigenous capabilities, India continues to depend on foreign technology and suppliers for certain reactor systems, specialised components and fuel-cycle inputs. This can expose projects to supply disruptions, export restrictions and geopolitical uncertainties.<\/li>\n<\/ol>\n<h2 class=\"blue-h2-box\"><span style=\"text-decoration: underline;\"><strong><span style=\"color: #000000; text-decoration: underline;\"><a id=\"toc5\"><\/a>What should be the way forward?<\/span><\/strong><\/span><\/h2>\n<ol>\n<li><strong><a href=\"https:\/\/forumias.com\/blog\/small-modular-reactors-explained-pointwise\/#What_are_the_benefits_of_Small_Modular_Reactors\" target=\"_blank\" rel=\"noopener\">Small Modular Reactors (SMRs)<\/a>:<\/strong> Indigenous Small Modular Reactors (SMRs) must be built at coal plant sites which would be retiring in the coming decades. SMRs offer the advantages of being safe, economical, compact and adaptable. Partnerships with NTPC and other thermal plant owners must be explored.<\/li>\n<li><strong>Expansion of indigenous PHWR reactors:<\/strong> The indigenous 700 MWe PHWR, must be expanded in fleet mode to add to the installed nuclear power capacity in India.<\/li>\n<li><strong>Scale up the Fast Breeder Reactor programme:<\/strong> With the PFBR achieving criticality in 2026, two additional FBRs must now be constructed at Kalpakkam, followed by four more beyond 2030. This will consolidate Stage II and generate sufficient U-233 from thorium blankets to fuel Stage III reactors.<\/li>\n<li><strong>Accelerate Stage III &#8211; Advanced Heavy Water Reactor (AHWR):<\/strong> Design validation and peer review of the AHWR is ongoing. The project must be formally launched at the earliest to utilise India&#8217;s vast thorium reserves, estimated to sustain energy needs for around 60,000 years.<\/li>\n<li><strong>Augmentation of safety of nuclear facilities:<\/strong>\u00a0There must be constant updation of safety skills of nuclear operators. Further, masses must be comprehensively sensitised about the functioning of nuclear power plants using highly intellectual individuals having mass appeal. <strong>For e.g.<\/strong>\u00a0Dr. APJ Abdul Kalam sensitizing the masses before the establishment of the Kudankulam nuclear power plant.<\/li>\n<li><strong>Ensuring Regulatory Autonomy:<\/strong>\u00a0The AERB, India\u2019s nuclear regulatory body, must be provided functional autonomy by removing its reporting from the Department of Atomic Energy (DAE).<\/li>\n<li><b data-path-to-node=\"5,1,0\" data-index-in-node=\"0\">Attract Private &amp; Captive Investment:<\/b> Mobilize domestic private capital and foreign investment to fund capital-intensive builds. <span class=\"citation-241 citation-end-241\">Commercial models like public-private partnerships (PPPs) can help build dedicated nuclear plants for energy-intensive industries (e.g. green hydrogen, steel, data centers).<\/span><\/li>\n<\/ol>\n<p><strong>Conclusion<\/strong>: India\u2019s nuclear energy programme offers a unique, self-reliant blueprint for clean power.
