PWR uses enriched uranium fuel.  \no Heavy Water: Deuterium Oxide absorbs fewer neutrons, allowing the reactor to sustain a chain reaction with unenriched uranium.  \no Light Water: Normal water absorbs more neutrons, demanding Low Enriched Uranium (3-5% U-235) to maintain continuous fission in PWRs.  \no Fuel Cycle: PHWRs allow continuous on-power refuelling, whereas PWRs necessitate shutting down thereactor for batch refuelling operations.  \no India: PHWRs form the backbone of India's current nuclear fleet, directly enabling the first stage of the ThreeStage Nuclear Programme.  \no Indigenous Technology: NPCIL has successfully mastered and scaled domestic 700 MWe PHWR designs, deploying them in active fleet mode.  \no Three-Stage Programme: PHWR spent fuel yields vital Plutonium-239, necessary for triggering the second-stage Fast Breeder Reactors.  \nNational Mission For Clean Ganga (NMCG)  \nThe National Green Tribunal (NGT) sought a response from the Centre on a petition challenging the recent amendments notified by the National Mission for Clean Ganga (NMCG) .  \no NMCG: Operates as the registered society and primary implementation arm under the Ministry of Jal Shakti for comprehensive river rejuvenation.  \no Namami Gange: An integrated Central Sector Scheme executed by NMCG for pollution abatement, conservation, and river basin restoration.  \no Establishment: Evolved from the erstwhile National Ganga River Basin Authority, reconstituted under the Environment (Protection) Act, 1986 in 2016.  \no National Ganga Council: Serves as the apex and policy oversight body chaired by the Prime Minister of India for basin governance.  \no Ganga River Basin: Covers eleven riparian states and drains over twenty-six percent of India's landmass, supporting critical ecological and agricultural systems.  \no E-Flows: Legally mandated minimum environmental flow regimes maintain continuous ecological discharge across upper and lower stretches of the river.  \no River Ecology: Focuses on restoring longitudinal, lateral, and vertical ecological connectivity across the river channel and its active floodplains.  \no Biodiversity: Prioritises conservation of endemic riverine aquatic fauna, including the Gharial, Smooth-coated Otter, Golden Mahseer, and freshwater turtles.  \no Ganga Dolphin: Protects the endangered national aquatic animal (Platanista gangetica), serving as the apex biological indicator of overall river ecosystem health.  \no Funding: Implemented as a centrally funded umbrella scheme supported by multilateral developmental assistance from institutions like the World Bank.  \no Other Bodies:  \n\n| Feature | CPCB | National Ganga Council |\n| --- | --- | --- |\n| Legal/ Institutional Basis | Statutory Body\u003Cbr>under Water Act, 1974 | Statutory Authority under\u003Cbr>Environment\u003Cbr>(Protection) Act, 1986 |\n| Main Function | Nationwide pollution monitoring and industrial standard setting | Apex policy formulation\u003Cbr>and inter\u003Cbr>ministerial\u003Cbr>river\u003Cbr>coordination |\n\n22 August 2026  \n\n| Jurisdiction | Pan-India territorial jurisdiction | Ganga River Basin (Covering all\u003Cbr>11 basin states)","cbCaifATnA4XybqC","https://ap.wps.com/l/cbCaifATnA4XybqC","pdf",236739,"English","# Pressurised Heavy Water Reactors (PHWR) and Pressurised Water Reactors (PWR)\n# National Mission For Clean Ganga (NMCG)\n# National Education Policy (NEP) 2020","[{\"question\":\"What are the key differences between PHWR and PWR technologies?\",\"answer\":\"PHWR uses unpressurised heavy water as moderator and pressurised heavy water as coolant, while PWR uses ordinary light water for both high-pressure coolant and neutron moderation.
