Nuclear • swimming pool type research reactor “Apsara-upgraded” has become operational at Bhabha Atomic Research Centre (BARC), Trombay.  • Uranium contamination of ground water due to Mining Stage 1- Pressurized Heavy Water Reactor (PHWR)   
• Uranium deposits occur in the Dharwar rocks. • Protests in Jaitapur protests and Mithi Virdi         • fuelled by natural uranium & light water reactors,
• Geographically, uranium ores are known to occur in several locations along the Singbhum Copper belt • Reactor meltdown         • produce plutonium & electricity
• Fuel         • Heavy water is used as moderator and coolant.
• Nuclear Energy and Foreign Policy Nexus: • NSG         • U-238 → Plutonium-239 + Heat
Stage 2-Plutonium fuelled Fast Breeder Reactor
        • uses fast neutron reactors burning the plutonium-239 with the blanket around the core having uranium as well as thorium, so that further plutonium (ideally high-fissile Pu) is produced as well as U-233.
Stage 3- Advanced Heavy Water Reactors (AHWRs) 
        • Burn thorium-plutonium fuels
        • Breeds U-233 which can eventually be used as a self-sustaining fissile driver for a fleet of breeding AHWRs. 
        • An alternative stage 3 is molten salt breeder reactors (MSBR), which are firming up as an option for eventual large-scale deployment
International Thermonuclear Experimental Reactor • Limited risk of proliferation •  India-based Neutrino Observatory (INO), a major research facility proposed in Theni district of Tamil Nadu.
• No risk of meltdown: Fukushima-type nuclear accident
• Fusion doesn't emit harmful toxins &GHGs
• Sustainability- fuels are widely available and nearly inexhaustible. Deuterium can be distilled from all forms of water,
