Context

Following amendments to the Atomic Energy Act, 1962, the Department of Atomic Energy (DAE) has formalized the regulatory framework for inviting private sector participation in deploying Small Modular Reactors (SMRs) to replace aging captive coal power plants.

Core Features of SMRs

• Modular Design & Scalability: SMRs generate up to 300 MW(e) per unit. Their modular nature allows for factory fabrication and transport to sites, significantly reducing construction time and capital cost overruns compared to traditional 700 MW+ pressurized heavy-water reactors (PHWRs).
• Passive Safety Systems: They rely on natural circulation, convection, and gravity for cooling. In the event of a station blackout (similar to the Fukushima scenario), SMRs can safely shut down without external power or human intervention.

Policy & Regulatory Shifts

• Public-Private Partnerships (PPP): While the Nuclear Power Corporation of India Limited (NPCIL) and Bharatiya Nabhikiya Vidyut Nigam Limited (BHAVINI) remain central, private entities are now permitted to invest in the nuclear island’s secondary turbines and supply chain infrastructure.
• Decarbonization Hard-to-Abate Sectors: SMRs are targeted for industrial clusters requiring continuous baseload power and high-temperature steam (e.g., steel, aluminum, and green hydrogen production).

3. Western Ghats Eco-Sensitive Area (ESA) Final Notification

Syllabus: GS Paper III – Conservation, Environmental Pollution and Degradation, Environmental Impact Assessment

Context

After a decade of draft iterations and resistance from state governments, the Ministry of Environment, Forest and Climate Change (MoEFCC) has officially published the final Eco-Sensitive Area (ESA) notification for the Western Ghats, covering nearly 59,940 sq. km across six states.

Committee Precedents

• Gadgil Committee (WGEEP – 2011): Recommended classifying the entire Western Ghats as an ESA, dividing it into three ecologically sensitive zones with strict bans on mining and large dams.
• Kasturirangan Committee (2013): Diluted the Gadgil recommendations, proposing that only ~37% of the total area (representing the biologically rich, contiguous landscape) be brought under the ESA framework. The final notification aligns closely with this boundary.

Regulatory Prohibitions in the ESA

• Complete Ban: Commercial mining, quarrying, and sand mining are strictly prohibited. Existing mines must be phased out within five years.
• Red Category Industries: No new thermal power projects or highly polluting industries (as classified by the CPCB) can be established.
• Infrastructure Restriction: Townships and area development projects exceeding 50 hectares or 1,50,000 sq. meters of built-up area are banned, directly impacting unchecked hill-station urbanization.

4. RBI’s Unified Lending Interface (ULI): The Next DPI Leap

Syllabus: GS Paper III – Indian Economy, Banking Sector, Digital Infrastructure

Source:The Indian Express / PIB

Context

The Reserve Bank of India (RBI) has formally launched the Unified Lending Interface (ULI) nationwide, aiming to replicate the success of UPI in the credit sector by enabling frictionless, consent-based credit delivery to MSMEs and agricultural borrowers.

Architecture & Functionality

• Data Convergence: ULI acts as a digital middleware that connects multiple data providers (land records of various states, satellite imagery, GST data, account aggregators) with lenders (banks and NBFCs) through standardized APIs.
• Plug-and-Play Model: Reduces the turnaround time (TAT) for loan appraisals from weeks to minutes by eliminating the need for extensive physical documentation.
• Focus on “Thin-File” Borrowers: Specifically targets agricultural and MSME borrowers who lack conventional credit histories (CIBIL scores) by utilizing alternative data for cash-flow-based lending rather than asset-backed lending.

Economic Impact

Addresses the ₹25-lakh-crore credit gap in the MSME sector, serving as the third foundational pillar of India’s Digital Public Infrastructure (DPI) alongside Identity (Aadhaar) and Payments (UPI).

5. Delimitation Commission & Census 2026 Sensitivities

Syllabus: GS Paper II – Indian Constitution, Parliament and State Legislatures (Structure, Functioning, Conduct of Business)

Source:The Hindu

Context

With the decadal Census concluding its digital enumeration phase, political and constitutional debates have intensified regarding the impending lifting of the freeze on the delimitation of Lok Sabha constituencies, currently fixed under the 84th Amendment Act, 2001, up to the year 2026.

Constitutional Framework

• Article 82: Readjustment of allocation of seats in the House of the People to the States and division of each State into territorial constituencies after every census.
• The Freeze: The 42nd Amendment (1976) first froze the seat allocation based on the 1971 census to ensure states implementing successful family planning were not penalized. The 84th Amendment extended this freeze to the first census published after 2026.

The Federal Friction

• Demographic Divergence: Southern states (Kerala, Tamil Nadu, Andhra Pradesh) have achieved Total Fertility Rates (TFR) below the replacement level of 2.1, while northern states (UP, Bihar) continue to see population growth.
• Political Representation Risk: A purely population-based delimitation exercise post-2026 could shift significant parliamentary weight to northern states, causing deep apprehensions about federal equity and fiscal devolution.
