  • The subsidy amount is directly transferred to the consumer's bank account after the purchase.
  • Subsidy- A targeted subsidy of Rs.300 per 14.2 kg cylinder for up to 12 refills of 14.2 Kg equivalent domestic LPG is being provided to all PMUY consumers.
  • In addition, various State Governments have also been providing subsidized refills or further subsidies to PMUY beneficiaries.
  • Key Features of Scheme
    • To streamline the subsidy distribution process for LPG cylinders.
    • To reduce misuse and diversion of subsidized LPG.

Type of Reactors

During the 2024 Budget speech, the Finance Minister highlighted small modular reactors (SMRs) as a promising technology.

  • Bharat Small Reactors are compact nuclear reactors designed to generate electricity on a smaller scale than traditional large nuclear power plants.
  • The BSRs will be based on India's tried and tested 220-megawatt pressurized Heavy Water Reactor (PHWR) technology, of which 16 units are already operational in the country.

A pressurized heavy-water reactor (PHWR) is a nuclear reactor that uses heavy water (deuterium oxide D2O) as its coolant and neutron moderator.

Feature

Large Conventional Reactors

Small Modular Reactors (SMRs)

Micro Reactors

Power Output

1000 - 1700+ MW

10 - 300 MW

< 10 MW

Size

Very large, requires significant space

Modular, smaller footprint

Minimal, compact design

Construction Time

5-10 years

3-5 years

1-3 years

Scalability

Limited, typically single unit

High, can be added incrementally

Very high, suitable for remote or small-scale applications

Fuel Cycle

Often uses advanced fuels like TRISO fuel

Economic Model

Economies of scale, centralized power generation

Cost-effective through factory assembly and modular construction

Cost-effective for niche markets and remote locations

Environmental Impact

High impact due to large footprint and water usage

Lower impact, more efficient land and water use

Minimal impact, designed for minimal environmental footprint

Grid Compatibility

Requires robust, stable grid

Can support both large and small grids

Ideal for microgrids and isolated applications

Use Cases

Base load power generation for large urban centers

Flexible use for urban, industrial, and rural areas

Remote areas, military bases, disaster recovery, small communities

  • Objective- SMR reactors represent a significant shift in India's nuclear energy strategy, aiming to make nuclear power more accessible and versatile.
  • PPP model- The government plans to partner with the private sector to set up Bharat Small Reactors and conduct R&D on small modular reactors and new nuclear technologies.
