IIT Hyderabad Launches ANUGYAN: 3-Month Nuclear Tech Programme for 100 GWe Target by 2047

Indian Railways Launches First LNG-Diesel Dual-Fuel DEMU Train; 40% Diesel Replacement, Rs 23.9 Lakh Annual Savings

Indian Railways has launched its first LNG-diesel dual-fuel DEMU train from Sabarmati, Gujarat, capable of replacing 40% diesel consumption. This follows the hydrogen train launched in July 2026, marking a strategic shift towards alternative fuels to reduce costs and emissions. For exam aspirants, this is a key case study in energy transition and infrastructure modernization.

Anil Kakodkar Advocates Thorium Fuel in PHWRs to Accelerate India's Nuclear Self-Reliance

Top nuclear scientist Anil Kakodkar proposes introducing thorium fuel in India's indigenous PHWR fleet to expedite utilisation of abundant thorium reserves and achieve nuclear fuel self-reliance, addressing growing energy demands and global uranium supply constraints.

India Targets 100 GW Nuclear Capacity by 2047, 5 New Reactors This Decade for AI & Chip Demand

PM Modi announced a target of 100 GW nuclear power by 2047 and 5 new reactors this decade, driven by soaring electricity demand from AI, semiconductors, and data centres. The SHANTI Act and draft rules now enable private participation, with a focus on small modular reactors (SMRs) for faster deployment and grid flexibility.

PM Modi Pitches India as Trusted Chip Hub, Launches Semicon 2.0 ₹1.27 Lakh Cr Programme

PM Modi inaugurated SEMICON India 2026, announcing Semicon 2.0 (₹1.27 lakh crore) to build a comprehensive semiconductor ecosystem. India aims to meet global demand for trusted chip manufacturing, with major investments from Applied Materials ($5B) and Lam Research (₹10,000 Cr). This is crucial for prelims (data points) and mains (Atmanirbhar Bharat, tech policy).

NPCIL Commences Fuel Loading at RAPP-8: 4th Indigenous 700 MWe PHWR in Fleet Mode

NPCIL has started initial fuel loading (IFL) at Unit 8 of Rajasthan Atomic Power Project (RAPP-8), a 700 MWe indigenous pressurised heavy water reactor (PHWR). This marks a major step in India's fleet-mode nuclear expansion, with commercial operation expected in 2026-27. For exams: understand PHWR technology, AERB's role, and the commissioning sequence (IFL → FAC → power generation).

Subsea Cables Carry 99% Internet Traffic: Vulnerabilities, Ownership Concentration & India's Resilience Plan

Subsea cables carry over 99% of global internet traffic, yet their supply chain is concentrated among a few private players and hyperscalers, making them vulnerable to sabotage, cyberattacks, and economic disruption. Recent NATO, Finland, and China incidents highlight intensifying threats, while India is building repair capacity via a DoT single-window clearance portal. This is a high-yield topic for GS3 infrastructure, science-tech, and security questions.

KAVACH Version 4.0 Commissioned on SCR: India’s Indigenous Automatic Train Protection System Explained

KAVACH, India's indigenous Automatic Train Protection (ATP) system, has been upgraded to Version 4.0 and commissioned on the South Central Railway's Malkajgiri–Kamareddi section over 108 route km. This is crucial for UPSC as it touches infrastructure, safety technology, and comparisons with global systems like ETCS, ATC, and PTC. The article also links to Sam Pitroda committee recommendations on railway modernisation.

Kudankulam Nuclear Reactor Costs Surge 55%: Impact on India's Nuclear Expansion Plans

Cost of four under-construction nuclear reactors at Kudankulam has risen by 55% to ₹1,38,330 crore, driven by Russia-Ukraine war. This poses a challenge to India's ambitious nuclear expansion plans and could increase electricity tariffs, especially as the government opens the sector to private participation.
