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).

IN-SPACe Releases Planned Re-entry Guidelines: Safety Threshold 1 in 10,000, Mandates Third-Party Liability Insurance

IN-SPACe has released new guidelines for planned re-entry of space objects, establishing a safety threshold of 1 in 10,000 risk to humans and mandating third-party liability insurance for private operators. This is crucial for India's human spaceflight mission Gaganyaan and the growing private space sector.

Climate Change Intensifies Clear Air Turbulence: 55% Rise in Severe CAT Over North Atlantic, DGCA Investigates Air India Incident

Climate change is making mid-flight turbulence, especially clear air turbulence (CAT), more frequent and severe. A 2023 study found severe CAT over the North Atlantic rose over 55% in four decades. For exam aspirants, this links climate change impacts to aviation safety, DGCA's regulatory role, and passenger safety protocols.

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.

DAE Proposes Reducing Land Need for 220 MWe Nuclear Reactors to 90 Hectares

The Department of Atomic Energy informed Parliament that land requirement for 220 MWe small nuclear reactors could be reduced from 330 hectares to about 90 hectares, subject to radiological impact assessment. This is part of India's push for Small Modular Reactors (SMRs) and opening the nuclear sector to private participation, with exclusion zones also proposed to be relaxed. The move is critical for energy security and decarbonization of hard-to-abate industries.

Doppler Weather Radars: 51st DWR Inaugurated at Sambalpur Under Mission Mausam

India's 51st Doppler Weather Radar was inaugurated in Sambalpur, Odisha, boosting weather forecasting under Mission Mausam. This expansion enhances early warning systems for cyclones, thunderstorms, and heavy rainfall, a core exam topic for disaster management and science-tech.

NALCO Sets Up Pilot Plants in Odisha for Rare Earth Recovery from Fly Ash & Red Mud - Critical Minerals Security

India moves towards self-reliance in rare earth elements (REE) critical for defence, electronics, and renewable energy. NALCO's indigenous pilot plants in Odisha recover REE from fly ash and red mud, reducing import dependence and advancing circular economy goals.

UK Met Office Forecasts Record El Nino >3°C; 2027 Likely Hottest Year on Record

The UK Met Office has forecast the strongest El Nino in over a century, with Pacific sea surface temperatures rising over 3°C above normal. This unprecedented event could make 2027 the hottest year globally, impacting global weather patterns including drier conditions in India and severe droughts in South America and the West Pacific.
