{GS1 – Geo} Dimensions of Uranium Enrichment

• Context (AJ|FP): The U.S. has demanded Iran halt all uranium enrichment as a central condition of the ongoing 2026 war negotiations.

About Uranium

• Uranium is a naturally occurring, silvery-white, metallic radioactive element with a very high density.
• Isotopes: It occurs naturally in three primary isotopes:
  1. U-238 is the most abundant isotope, comprising over 99.2% of natural uranium.
  2. U-235 constitutes 0.7% of natural uranium. It is the sole naturally occurring fissile isotope.
  3. U-234 is the rarest isotope, present only in trace amounts of about 0.005% of natural uranium.
• Health Risks: Uranium poses chemical and radiological risks. Ingestion damages the kidneys, while inhaled dust or radon (its decay product) increases the risk of lung cancer.
• Applications: It fuels nuclear reactors, weapons and produces medical isotopes for cancer treatment and diagnostic imaging.
  • Military Uses: Depleted uranium is used in armour-piercing projectiles, tank armour, and aircraft control-surface counterweights.

Distribution of Uranium

• Top Producers: Kazakhstan leads in uranium production, followed by Canada and Namibia. The three nations collectively account for 75% of the world’s supply.
• Reserve Gap: Australia holds the largest known uranium reserves (roughly 28%) but currently ranks fourth in production.
• India: India ranks 13^th in reserves and 9^th in production, contributing less than 1% of global supply.
• State Share: Andhra Pradesh accounts for ~50% of India’s identified uranium resources, followed by Jharkhand and Meghalaya.

Stages of Uranium Enrichment

1. Extraction: Uranium ore is crushed and refined into a concentrated powder known as yellowcake.
2. Hydrofluorination: Hydrogen fluoride gas reacts with uranium dioxide (derived from yellowcake) to form emerald-green crystals of uranium tetrafluoride.
3. Fluorination: The crystals are further processed into uranium hexafluoride, which is gasified when heated for isotope separation.
4. Enrichment: High-speed centrifuges spin the gas to increase the concentration of fissile U-235.
5. Cascading: The gas passes through thousands of connected centrifuges, gradually reaching the concentration required for nuclear fuel.
6. Deconversion: The gas is chemically converted back into the black uranium dioxide powder.
7. Sintering: The powder is compressed and baked at extreme temperatures into dense, heat-resistant ceramic pellets.
8. Zirconium Cladding: The finished pellets are sealed inside corrosion-resistant zirconium alloy tubes, forming fuel rods bundled for the reactor.

Different Levels of Uranium Enrichment

1. Low-Enriched Uranium: Contains 0.7%-20% U-235 and serves as the primary fuel for nuclear energy.
   • Reactor Grades: Enrichment of 3%-5% fuels nuclear power plants, while 5%-20% powers advanced reactors and Small Modular Reactors (SMRs).
2. Highly Enriched Uranium: Contains 20% or more U-235 and is strictly monitored internationally due to its potential for military misuse.
   • Weapons Grade: Enrichment to 90% enables the rapid, uncontrolled chain reaction required for nuclear explosives.
3. Byproducts and Natural States: These forms either exist before the enrichment process begins or as by-products of its completion.
   • Natural Uranium: Retains its original 0.7% U-235 and can fuel specialised reactors like CANDU.
   • Depleted Uranium: It is a byproduct with less than 0.3% U-235, used in radiation shielding and armour-piercing applications.

{GS2 – Governance} CERC Proposes Market Coupling for ‘One Grid, One Price’

• Context (FE): The Central Electricity Regulatory Commission (CERC) issued a draft regulation to formally introduce market coupling in India.

• Objective: It aims to unify the power market by shifting from a decentralised system to a centralised price benchmark.

Key Provisions of the Draft Regulations

• Institutional Framework: Grid Controller of India Limited (Grid India) is designated as the sole Market Coupling Operator (MCO) responsible for centralising price discovery.
• Initial Scope: The regulations will apply to the Day-Ahead Market (DAM) and Real-Time Market (RTM) segments in the first phase of implementation.
• Price Calculation: MCO will calculate prices by combining buyer and seller bids to maximise total economic surplus.
• Standardised Bidding: Power exchanges must collect bids in a uniform format and transmit anonymised data to the MCO for centralised processing.
• Uniform Pricing: The operator will use a common algorithm to discover a single Uniform Clearing Price (UCP) across all participating exchanges.

Current Operational Framework of the Indian Power Market

• Separate Algorithms: Each power exchange uses its own private algorithm to determine prices only from its pool of buyers and sellers.
• Exchange Choice: Market participants choose freely among three power exchanges (IEX, PXIL, and HPX) to place their bids.
• Capacity Allocation: National Load Despatch Centre allocates transmission capacity to each exchange individually, based on each exchange’s own auction results.
• Proprietary Data: Each exchange keeps bidding data proprietary and does not share it with competitors or any central operator before price discovery.
• Price Divergence: Separate auctions frequently produce different final prices for the same electricity product across trading platforms.

{GS2 – Governance} Supreme Court Directions on Disabled-Friendly Prisons **

• Context (TH): The Supreme Court has directed a high-powered committee to prepare a plan for disabled-friendly prisons across India.

• The committee, chaired by Justice S. Ravindra Bhat, will expand its mandate to include accessibility, assistive support, and security considerations.

Issues of Disabled Prisoners in India

• Data Gap: India lacks official data on prisoners with disabilities, unlike global estimates where ~16% of the population (WHO) and up to 38% prisoners (US data) have disabilities.
• Human Rights Violations: Cases like G. N. Saibaba and Stan Swamy show denial of basic aids, healthcare, and dignity in prisons.
• Institutional Gaps: Major reforms (Model Prison Manual, Mulla Committee, 2023 Prison Act) ignored disability inclusion, despite focusing on women and transgender prisoners.
• Legal-Implementation Gap: Despite protections under the Rights of Persons with Disabilities Act, prison systems lack effective enforcement and inclusion.
• Poor Infrastructure & Care: Absence of ramps, assistive devices, specialised medical care, and mental health support worsens conditions for disabled inmates.

Reform Measures for Disabled Friendly Prisons

• Accessible Infrastructure: Ensure barrier-free prisons with ramps, accessible toilets, and facilities tailored to prisoners with disabilities (e.g. Nelson Mandela Rules by UN).
• Assistive Devices: Provide need-based aids like wheelchairs, hearing devices, and support equipment with standardised procurement and maintenance.
• Specialised Healthcare: Guarantee continuous medical care, including disability-specific treatment and monitoring of chronic conditions (e.g. monthly camp for PwD in Gwalior Jail).
• Social Support: Enhance visitation rights and communication access to maintain family contact and emotional well-being.
• Legal Support: Strengthen legal aid (by NALSA) and enforce accountability under the Rights of Persons with Disabilities Act to protect prisoners’ rights.
• International Best Practices: Countries like the UK, Netherlands, and Australia provide disability-specific prison guidelines and use peer support systems and suicide prevention protocols.

{GS2 – IR} ILO Releases Report on Psychosocial Risks of Toxic Workplace Culture **

• Context (TH): International Labour Organisation (ILO) recently released a report highlighting a health crisis from toxic workplace culture and work-related stress.

Key Findings of the Report

• Risk Factors: The report listed five main psychosocial risks — long working hours, job strain, effort-reward imbalance, job insecurity, and workplace harassment.
• Mortality: Over 8.4 lakh deaths annually are linked to these risks, mainly due to cardiovascular diseases, mental disorders, and suicide.
• Economic Impact: These risk factors cause an estimated annual loss of 1.37% of global GDP.
• Health Burden: They result in loss of nearly 45 million disability-adjusted life years (DALYs) each year.
• Exposure: 35% of workers work over 48 hours weekly; 23% face workplace violence or harassment, with psychological violence the most prevalent (18%).

Recommended Pathways

• Structural Redesign: Ensure fair workloads, greater job predictability, and stronger organisational justice.
• Collectivisation: Strengthen trade unions, collective bargaining, and social dialogue to turn legal safeguards into enforceable protections.
• Policy Integration: Address psychosocial risks with parity to physical and chemical hazards within national Occupational Safety and Health (OSH) policies.
• Monitoring: Develop systematic policy evaluation and participatory monitoring to continually assess and improve psychosocial conditions.

{GS3 – IE} India’s Growth Story Beyond GDP Rankings

• Context (IE): IMF estimates rank India 6^th globally in GDP, despite strong growth, due to statistical and external factors.

Limitations of Global GDP Rankings

• Nominal Distortion: GDP rankings (in dollar terms) fluctuate due to exchange rate movements, not actual economic performance.
• GDP Revision Effects: Changes in methodology and base year can alter past estimates, reshaping growth narratives without real change.
• Data Quality: Delays & inconsistencies in data collection can reduce the reliability of growth estimates.
• Comparability Issues: Differences in statistical methods across countries make global GDP rankings less accurate and comparable.

Issue with GDP as a Measure of Economic Development

• Ignores Distribution: High GDP does not reflect income inequality (top 1% holds ~22.6% of national income) or who benefits from growth.
• No Welfare Insight: India ranks 130 in UNDP Human Development Index despite being in a top 6 GDP economy; ~16% population is multidimensionally poor (NITI Aayog).
• Jobless Growth Blindspot: GDP growth may rise even when employment generation is weak.
• Structural Issues Hidden: Over 45% workforce in agriculture contributes ~15% GDP; ~90% workforce is in the informal sector (ILO).
• Regional Disparities: National GDP ignores intra-country inequalities across states/regions (e.g. 5 southern states contribute ~30% of GDP).
• Informal Economy: A large informal sector (~90%) leads to underestimation or mismeasurement of actual economic activity.

{GS3 – IE} Digital Payments E-Mandate Framework, 2026 *

• Context (ET): Reserve Bank of India (RBI) issued Digital Payments – E-Mandate Framework, 2026 under the Payment and Settlement Systems Act, 2007.

• The framework consolidates earlier circulars to standardise e-mandate rules for cards, UPI, and Prepaid Payment Instruments (PPIs).
• Registration: Every e-mandate requires one-time registration with an Additional Factor of Authentication (AFA) to establish verified customer consent.
• Thresholds: Auto-debits up to ₹15,000 can proceed without AFA; for insurance, mutual funds, and credit card bills, this limit is ₹1 lakh. Full AFA is required above these limits, and for registration.
• Customer Rights: Every mandate must specify a validity period, and customers may modify, withdraw, or opt out at any time.
• Zero-Cost Access: Banks, issuers, and payment system providers cannot levy any charges for using e-mandate payment facilities.
