Small Modular Reactors in Andhra Pradesh: Nara Lokesh Invites Russia’s Rosatom

Leave a Comment / Daily Current Affairs, Andhra Pradesh Current Affairs, Science and Technology Current Affairs / PSC Chronicles Team

Why in News?

Andhra Pradesh IT and HRD Minister Nara Lokesh invited Rosatom, Russia’s state-owned nuclear technology corporation, to establish Small Modular Reactors (SMRs) in Andhra Pradesh for power generation. He also proposed setting up a Nuclear Medicine and Food Irradiation Centre to boost India’s pharmaceutical sector and agricultural exports.

Key Facts for Prelims

Rosatom is Russia’s state-owned nuclear energy corporation and a global nuclear technology leader.
SMRs produce up to 300 MWe per module — roughly one-third of a conventional nuclear plant’s output.
SMRs are factory-fabricated and modular — components are transported by truck or train and assembled on-site (plug-and-play model).
They use nuclear fission to generate heat, then steam, then electricity (clean energy).
SMRs have a significantly smaller physical footprint compared to traditional nuclear power plants.
India is developing three indigenous SMR models to support decarbonization and energy security.

India’s Indigenous SMR Models (Exam Static)

BSMR-200 (Bharat Small Modular Reactor): 220 MWe, Pressurized Water Reactor (PWR), uses Slightly Enriched Uranium (SEU). Designed for commercial deployment and replacing retiring fossil-fuel plants.
SMR-55: 55 MWe modular PWR. Focuses on flexible, localized power generation.
HTGCR (High-Temperature Gas-Cooled Reactor): 5 MWth. Primarily for hydrogen generation — supports industrial decarbonization and transport.

Interconnected Exam Concepts

Nuclear Fission vs. Fusion: SMRs use fission (splitting heavy atoms like Uranium). Fusion (used in stars) is still experimental for power generation.
Pressurized Water Reactor (PWR): Most common type of nuclear reactor worldwide; uses water as both coolant and moderator.
India’s Nuclear Programme: Governed by the Atomic Energy Act, 1962. The Department of Atomic Energy (DAE) oversees it; the Nuclear Power Corporation of India (NPCIL) operates plants.
India’s Three-Stage Nuclear Programme: Stage 1 (PHWRs using natural uranium), Stage 2 (Fast Breeder Reactors using plutonium), Stage 3 (Thorium-based reactors). SMRs are complementary to this.

VB-G RAM G Scheme 2026: Replaces MGNREGA – UPSC & State PSC Prelims Notes

Leave a Comment / Daily Current Affairs, Andhra Pradesh Current Affairs, Indian Economy Current Affairs / PSC Chronicles Team

The Andhra Pradesh Cabinet officially approved the implementation of the Viksit Bharat Guarantee for Rozgar and Aajeevika Mission (Gramin) – VB-G RAM G in the state, effective July 1, 2026. This scheme replaces the two-decade-old MGNREGA program and is critical for UPSC, APPSC, and TGPSC Prelims from the perspectives of rural employment, social security, and cooperative federalism.

Why in News

Andhra Pradesh became one of the early states to officially approve the nationwide rollout of VB-G RAM G, which repeals and replaces MGNREGA effective July 1, 2026. The scheme enhances employment guarantees and restructures funding between the Centre and States.

What is VB-G RAM G?

Full Form: Viksit Bharat Guarantee for Rozgar and Aajeevika Mission (Gramin)

A Centrally Sponsored Scheme that replaces MGNREGA (Mahatma Gandhi National Rural Employment Guarantee Act, 2005)
Effective date in AP: July 1, 2026
Objective: Enhance rural employment, create durable public assets, and ensure livelihood security

Key Features of VB-G RAM G

Enhanced Employment Guarantee: Increased from 100 days (MGNREGA) → 125 days per financial year per rural household
Work Provision Timeline: Local administration must provide employment within 15 days of application
Four Infrastructure Verticals: Employment strictly integrated with creating durable public assets in — (1) Water security, (2) Core rural infrastructure, (3) Livelihood infrastructure, (4) Extreme weather mitigation
Agricultural Safeguard Pause: State governments can notify a collective 60-day no-work period during peak sowing and harvesting seasons to avoid farm labour shortages
Unemployment Allowance: If work is not provided within 15 days — minimum 1/4th of wage rate for the first 30 days, and 1/2 of wage rate for the remaining period, paid from the state’s own budget
Delay Compensation: Wages must be credited weekly or within 15 days of closing muster roll. Delay beyond 16th day = compensation at 0.05% of unpaid wages per day

Funding Pattern

Category	Centre : State Ratio
General States	60 : 40
North-Eastern & Himalayan States	90 : 10
Union Territories (without legislature)	100% Central funding

MGNREGA vs VB-G RAM G

Parameter	MGNREGA	VB-G RAM G
Employment Guarantee	100 days/year	125 days/year
Work within	15 days	15 days
Agricultural Pause	Not specified	60-day collective pause

Static/Exam Connections

Article 41 (DPSP): The State shall make effective provision for securing the right to work — legal basis for employment guarantee schemes
Article 43 (DPSP): State shall endeavour to secure a living wage and decent standard of life for workers
Centrally Sponsored Schemes (CSS): Funded jointly by Centre and States; implemented by states as per national guidelines
MGNREGA (2005): Was renamed from NREG Act to MGNREGA in 2009 in honour of Mahatma Gandhi; now repealed by VB-G RAM G
Finance Commission: Determines Centre-State fiscal transfers; CSS funding follows separate norms
Cooperative Federalism: The 60:40 funding ratio reflects greater financial responsibility on states vs MGNREGA’s earlier norms
