It is located in the Tirunelveli district of Tamil Nadu. The plant has become central to India\u2019s effort to boost domestic electricity production, strengthen energy security, and diversify energy sources. Since its launch, the project has been shaped by technological collaboration with Russia, major cost escalations, strong local opposition, multiple safety reviews, and a steady expansion of units to achieve a planned 6,000 MW capacity.<\/span><\/p>\n<h2><b>Kudankulam Nuclear Power Plant<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The Kudankulam Nuclear Power Plant (KKNPP), also known as Kudankulam NPP, is the largest nuclear installation in India. The construction began on 31 March 2002 and the plant uses Russian VVER-1000 reactors developed in partnership with Atomstroyexport and the Nuclear Power Corporation of India Limited (NPCIL). With a planned six units of 1,000 MW each, the plant will reach 6,000 MW capacity. NPCIL announced a tariff of \u20b94.29\/ kWh in 2015 for electricity supplied from the plant. Unit 1 was synchronized to the grid on 22 October 2013, and successive units have followed, making the facility a key asset in India\u2019s power sector.<\/span><\/p>\n<p><strong>Also Read: <a href=\"https:\/\/vajiramandravi.com\/current-affairs\/nuclear-power-plants-in-india\/\" target=\"_blank\">Nuclear Power Plants in India<\/a><\/strong><\/p>\n<h2><b>Kudankulam Nuclear Power Plant Historical Background<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The Kudankulam Nuclear Power Plant project emerged from a 1988 Indo-Soviet agreement revived after geopolitical changes.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The intergovernmental agreement was signed in 1988 by Prime Minister Rajiv Gandhi and Soviet leader Mikhail Gorbachev for two reactors.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The project remained dormant for a decade due to the dissolution of the USSR and objections from the United States under Nuclear Suppliers Group norms.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Revival occurred on 21 June 1998, restarting planning efforts and opening doors for renewed Indo-Russian nuclear cooperation.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Work began on 31 March 2002 with an initial target for Unit 1 by 2007, later postponed due to consistent interruptions.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A dedicated small port opened in 2004 to safely transport large reactor components otherwise at risk on road routes.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Negotiations in 2008 explored four additional reactors of 1,200 MW each, but these units never entered planning due to protests and technical reasons.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Construction of Units 3 and 4 began in 2017 after AERB approvals, followed by Units 5 and 6 in 2021.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Unit 5 is expected to be commissioned in December 2026 and Unit 6 by September 2027.<\/span><\/li>\n<\/ul>\n<h2><b>Kudankulam Nuclear Power Plant Units<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The Kudankulam Nuclear Power Plant consists of six VVER-1000 units, out of which two are operational and four are under construction.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Unit 1: 1,000 MW;
