<\/a>What is the present status of Nuclear Energy in India?<\/strong><\/span><\/h2>\n\n\n\n\n\n
Civil Nuclear Power<\/strong><\/td>\nNumber of Operational Nuclear Power Plants:<\/strong>\u00a0India has 22 operational nuclear reactors<\/span> with a total installed capacity of 7,480 MW (as of 2024).
\nNew Nuclear Projects:<\/strong>\u00a0Several new reactors are under construction, including Kudankulam<\/strong> (Units 3-6)<\/span>, Gorakhpur Haryana Anu Vidyut Pariyojana<\/span><\/strong>, and Kaiga<\/strong> Units 5 & 6<\/span>, expected to add nearly 7,000 MW in the next decade which will add 8,000 MWe by 2031.
\nIndigenous Reactor Technology:<\/strong>\u00a0India has developed Pressurized Heavy Water Reactors<\/span> (PHWRs), Prototype Fast Breeder Reactor<\/span> (PFBR), and is progressing towards thorium-based Advanced Heavy Water Reactor<\/span> (AHWR).<\/td>\n<\/tr>\n
Nuclear in Defense <\/strong><\/td>\nNuclear-Powered Submarines:<\/strong>\u00a0India has developed INS Arihant<\/span>, the country’s first indigenous nuclear-powered ballistic missile submarine (SSBN), and is working on INS Arighat and additional units.
\nNuclear-Capable Missiles:<\/strong>\u00a0India has a range of nuclear-capable missiles, including Agni<\/span> (I-V<\/span>), Prithvi<\/span>, and K-15<\/span> (Sagarika).
\nNuclear Research and Collaborations:<\/strong>\u00a0India collaborates with the IAEA<\/span>, Russia<\/span> (Rosatom), and the US<\/span> (123 Agreement) for nuclear technology exchange, while advancing indigenous research at BARC, IGCAR, and NPCIL.<\/td>\n<\/tr>\n
Technologies in Use and Development <\/strong><\/td>\nPHWRs:<\/strong>\u00a0The backbone of India\u2019s nuclear program, using natural uranium as fuel.
\nFast Breeder Reactors (FBRs):<\/strong>\u00a0The 500 MWe Prototype Fast Breeder Reactor (PFBR) is under development, aiming to use plutonium and thorium for fuel.
\nMolten Salt Reactors (MSRs):<\/strong>\u00a0It is still in the research phase, focusing on thorium utilization.
\nSmall Modular Reactors (SMRs):<\/strong>\u00a0These reactors are being explored for deployment at retiring coal plant sites.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

<\/a>What is the significance of Nuclear Energy?<\/strong><\/span><\/h2>\n

1. Energy Security: <\/strong>The three-stage nuclear program aims to utilize thorium, ensuring long-term energy independence. Nuclear power accounts for about 3% of India\u2019s electricity generation<\/span> but is targeted to reach 22% by 2050<\/span>. Nuclear energy delivers base load power, which is essential to building modern economies.<\/p>\n

2. Clean Energy:<\/strong>\u00a0Nuclear power is a low-carbon energy source, contributing to India\u2019s Net Zero by 2070 goal<\/span>. It complements renewable energy by providing base-load power, ensuring grid stability. India’s electricity generation capacity at present is 480GW. It will have to grow 5-fold for India to achieve the developed economy status by 2047. On the other hand, India also has the target to become net zero by 2070, thus India will not be able to rely on fossil fuels for its growth. Renewable energy (including solar, hydro, wind & biomass) is estimated to provide 20% of the demand & up to 25% with investments in battery & pumped storage. Therefore, the obvious candidate to fuel India’s energy growth is nuclear power.<\/p>\n

3. <\/strong>Space Exploration:<\/strong>\u00a0Nuclear energy powers radioisotope thermoelectric generators<\/span> (RTGs) for deep-space missions, such as Chandrayaan and Mangalyaan.<\/p>\n

4. Defence:<\/strong>\u00a0Nuclear-powered submarines and missiles enhance India\u2019s strategic deterrence and second-strike capability. Indigenous development of nuclear reactors and weapons reduces dependency on foreign technology.<\/p>\n

5. Medical Advancements:<\/strong>\u00a0BARC-developed radiopharmaceuticals aid in cancer treatment, with India producing over 50 radioisotopes for medical use<\/span>.<\/p>\n

6. Food Preservation:<\/strong>\u00a0Nuclear technology enhances food irradiation, increasing shelf-life and preventing spoilage.<\/p>\n
