India’s First Private Heavy Water Test Facility
India’s nuclear sector has taken a significant step by involving private players in testing equipment for upgrading depleted heavy water, a process previously handled by Bhabha Atomic Research Centre (BARC).
Key Points:
- TEMA India’s Role: Mumbai-based TEMA India opened a test facility in Achchad, Palghar, to manufacture and test distillation columns for heavy water upgradation, supporting Pressurised Heavy Water Reactors (PHWRs).
- Technology Transfer: Facility built under BARC’s technology transfer and NPCIL’s purchase order, reflecting public-private synergy under Atma-Nirbhar Bharat.
- Significance: First batch of tested equipment dispatched for Rawatbhata Nuclear Power Plant (RAPP-8), set to go critical by December 2025.
- Heavy Water (D2O): Used as coolant and moderator in PHWRs, requiring 99.9% purity; depleted D2O is upgraded via distillation.
- Nuclear Goals: India targets 100 GW nuclear capacity by 2047, with 24 reactors (8,780 MW) operational and 13.6 GW under construction.
UPSC Relevance:

China’s Yarlung Tsangpo Hydropower Project and UN Watercourses Convention
China’s $167.8 billion hydropower project on the Yarlung Tsangpo River, launched on July 19, 2025, raises concerns for lower riparian India, highlighting the importance of the UN Watercourses Convention.
Key Points:
- Project Details: Located in Medog County, Tibet, 30 km from India, it will generate 300 billion kWh annually, involving five cascade hydropower plants and river diversion.
- India’s Concerns: Potential disruption of Brahmaputra’s flow (25–35% from Tibet), flooding risks, ecological damage, and seismic hazards in Seismic Zone V.
- UN Watercourses Convention (1997): Promotes “equitable and reasonable utilisation” and “no significant harm” principles, part of customary international law, though neither India nor China is a signatory.
- China’s Track Record: Limited cooperation with India under three MoUs, with intermittent suspension of wet-season hydrographic data.
- Brahmaputra Path: Originates near Mount Kailash, enters India as Siang in Arunachal Pradesh, becomes Brahmaputra in Assam, and flows into Bangladesh as Jamuna/Meghna.
UPSC Relevance:
- Prelims: Map work (Brahmaputra’s course), UN Watercourses Convention, Harmon Doctrine.
- Mains: GS II (India-China relations, international law); analyze India’s rights as a lower riparian and China’s upper riparian actions.
ICJ’s Climate Change Advisory Opinion
The International Court of Justice (ICJ) delivered a landmark advisory opinion on July 23, 2025, affirming states’ legal obligations to address climate change, initiated by Vanuatu.
Key Points:
- Case Origin: Vanuatu led a UNGA resolution (March 2023, co-sponsored by 130+ countries) seeking ICJ’s opinion on states’ climate obligations and consequences of inaction.
- ICJ Ruling: States must reduce GHG emissions under international law (UNFCCC, Paris Agreement, UNCLOS), regulate fossil fuels, and provide reparations for climate harm.
- Human Rights Link: Climate inaction violates rights to life, health, and adequate living standards.
- India’s Position: Did not co-sponsor but did not oppose; balances climate action (50% renewables by 2030, net-zero by 2070) with development needs.
- Impact: Strengthens climate litigation, supports vulnerable nations, and influences COP30 and Loss and Damage Fund discussions.
UPSC Relevance:
- Prelims: ICJ structure, advisory vs. contentious cases, climate treaties.
- Mains: GS II (International Organizations), GS III (Environment); discuss climate justice and India’s role in global climate diplomacy.
Presidential Reference and Tamil Nadu Governor Case
The Supreme Court’s April 8, 2025, ruling on Tamil Nadu vs. Governor prompted a Presidential Reference under Article 143(1), raising questions about judicial overreach.
Key Points:
- April 8 Ruling: SC set a three-month timeline for Governors and the President to act on bills, citing implicit constitutional obligations for timely action.
- Presidential Reference: President Droupadi Murmu invoked Article 143(1) to seek SC’s advisory opinion on whether this timeline applies to the President’s powers under Article 201.
- Article 143(1): Allows the President to refer questions of law or fact of public importance to SC; opinion is non-binding but persuasive.
- Concerns: SC’s extension of timeline to presidential powers may constitute judicial overreach, as Article 201 sets no timeframe.
- Article 142: SC invoked its extraordinary powers to ensure justice, but critics argue it risks encroaching on executive prerogatives.
UPSC Relevance:
- Prelims: Articles 143, 201, 142; advisory jurisdiction; judicial overreach vs. encroachment.
- Mains: GS II (Polity, Federal Structure); analyze balance of power between judiciary and executive.
