The ultimate focus of the programme is on enabling the thorium reserves of India to be utilised in meeting the country\u2019s energy requirements.<\/p>\n\n\n\n<p><strong>Three stage nuclear power\nprogram:<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\"><li><strong>Stage 1- Pressurised heavy water reactor (PHWR): <\/strong>The first stage involved using natural uranium to fuel PHWR to produce electricity and Plutonium-239 as a byproduct. PHWRs were chosen for the first stage because:<ul><li>In 1960s, India had the efficient reactor design in terms of uranium utilisation. <\/li><li>Using Pressurised Heavy Water Reactors over Light Water Reactors was a correct and wise decision. While Pressurised Heavy Water Reactors used unenriched uranium, Light Water Reactors required enriched uranium. <\/li><li>Further, India could domestically produce the components of PWHR, as opposed to LWRs. Also the byproduct plutonium-293 would be used in the second stage.<\/li><\/ul><\/li><li><strong>Stage 2- Fast breeder reactor (FBR): <\/strong>The second stage involves using plutonium-239 to produce fuel, which would be used in Fast Breeder Reactors. Plutonium 239 undergoes fission to produce energy. Once a sufficient amount of plutonium-239 is built up, thorium will be used in the reactor, to produce Uranium-233. This uranium is crucial for the third stage.<\/li><li><strong>Stage 3- Advanced Heavy Water Reactor (AHWR): <\/strong>The main purpose of stage-3 is to achieve a sustainable nuclear fuel cycle. <ul><li>The advance nuclear system would be used a combination of Uranium-233 and Thorium. <\/li><li>India has vast thorium which would be exploited, using a thermal breeder reactor. <\/li><li>Thorium use was reserved for the last stage as despite of having significant availability, use of Thorium in production of energy has been full of certain challenges. It cannot be used directly. <\/li><li>Thorium absorbs the neutrons, which can more efficiently produce more Plutonium in Fast Breeder Reactor for a faster growth.<\/li><li>Thus, the ultimate objective of the above programme is to create capacity to use Thorium for sustainable production of nuclear energy and make India energy independent.<\/li><\/ul><\/li><\/ol>\n\n\n\n<p><strong>Challenges in 3 stage program:<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\"><li>Foremost challenge of Nuclear technology is safety\nand waste management. Incidents like Chernobyl, Fukushima are serious cause of\nconcern. If nuclear energy is generated adhering to the highest standards of\nsafety, there is less possibility of catastrophic accidents.<\/li><li>Availability of fissile material is also a cause\nof concern. Nuclear fuel is not available easily and need diplomatic efforts.<\/li><li>Land acquisition and selection of location for\nNuclear Power Plant (NPP) is also major problem in the country. NPP\u2019s like Kudankulam\nin Tamil Nadu have met with several delays due to the land acquisition related\nchallenges.<\/li><li>As India is not a signatory of NPT and NSG,\nnuclear supply is severely contained by sanctioned against India. This\nsituation has changed after 2009 waiver and bilateral civil nuclear energy\nagreements with many countries.<\/li><li>Reprocessing and enrichment capacity also\nrequired boost in India. For this India needs advanced technology to fully\nutilise the spent fuel and for enhancing its enrichment capacity.<\/li><\/ol>\n\n\n\n<p>To ensure the safety and security of using nuclear power there is need toensure maintenance of the skills base, continued effective safety regulation. Fostering progress on facilities for waste disposal and management must be given serious consideration. It is also important to maintain and reinforce international non-proliferation arrangements.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Demand of the question Introduction.
