Pre & Mains Notes

1. India’s Shift from Uranium to Thorium in PHWRs WHAT HAPPENED India’s nuclear scientists have called for an early shift towards domestic thorium in Pressurised Heavy Water Reactors (PHWRs). The move aims to reduce dependence on imported uranium and utilise India’s large thorium reserves. CORE ISSUE Achieving long-term nuclear energy security through greater utilisation of indigenous thorium resources. KEY DETAILS - Three-Stage Programme: India’s nuclear strategy progresses from uranium-based PHWRs towards thorium utilisation. - Resource Advantage: India has substantial thorium reserves but relatively limited domestic uranium resources. - Energy Security: Greater thorium use can reduce dependence on imported uranium and improve fuel security. - Future Reactors: Thorium-based systems such as AHWRs could support large-scale, long-term nuclear power generation. WHY IT MATTERS Thorium can strengthen India’s energy security and support long-term expansion of low-carbon nuclear power. It is particularly relevant as India seeks to expand nuclear capacity while reducing dependence on imported fuel. 2. Agentic AI in Digital Payments WHAT HAPPENED Agentic AI could transform digital payments by enabling AI agents to discover, compare and execute transactions autonomously. The concept is moving payments from user-initiated transactions towards goal-based purchasing. CORE ISSUE Balancing payment convenience and AI autonomy with security, consent and fraud risks. KEY DETAILS - Agentic Commerce: AI understands user goals, finds options, negotiates and completes transactions. - Agentic Payments: AI can select payment methods, initiate transactions and manage recurring payments. - Benefits: Personalised purchasing, price comparison, automated payments and reduced transaction friction. - Risks: Unauthorised transactions, fraud, privacy concerns and loss of consumer control. WHY IT MATTERS Could reshape India’s digital-payment ecosystem by making transactions more autonomous and personalised. Requires strong safeguards for consent, authentication, liability and data protection.

Pre & Mains Notes

1. Plastic Waste to Useful Materials WHAT HAPPENED India generates around 62,000 tonnes of plastic waste daily, creating major challenges for waste management. Researchers and industries are developing ways to recycle plastic into useful materials and fuels. CORE ISSUE Converting plastic waste from an environmental burden into useful resources through recycling and waste-to-value technologies. KEY DETAILS Recycling: Plastics can be converted into items like chairs, tables, window panes and packaging materials. Pyrolysis: Plastic waste can be thermally converted into fuel and useful chemicals. Hydrogen: Plastic waste can potentially produce hydrogen through processes such as gasification and photocatalysis. Other Uses: Plastic-derived materials can support roads, construction and industrial applications. WHY IT MATTERS Promotes a circular economy by reducing plastic pollution while recovering energy and materials. Can complement waste segregation, recycling and Extended Producer Responsibility efforts. GS Paper III — Environment & Science: Plastic pollution, waste management, circular economy, recycling technologies. 2. OneTag Facility WHAT HAPPENED NHAI rolled out OneTag, enabling vehicle owners to switch FASTag issuer banks without replacing the existing FASTag. The facility is integrated with NHAI’s Rajmargyatra app and the NETC ecosystem. CORE ISSUE Improving interoperability and consumer choice in electronic toll payments. KEY DETAILS - Like MNP: Users can change issuer banks while retaining the same FASTag sticker and Tag ID. - Porting Process: Rajmargyatra app → authentication → new bank selection → digital KYC → NPCI backend mapping. - No Hardware Change: Existing RFID tag continues working; toll-plaza operations remain unchanged. - Six-Month Gap: A mandatory cooling-off period applies between consecutive porting requests. WHY IT MATTERS Reduces inconvenience and gives motorists greater choice among FASTag issuer banks. Strengthens interoperability and digital public infrastructure in electronic toll collection.
