Why Does Nuclear Energy Matter?

From atomic fission to electricity

Nuclear power uses controlled atomic fission to release heat. This heat generates steam, which drives a turbine-generator. Nuclear generation has low operational greenhouse-gas emissions and can provide dependable electricity irrespective of sunshine or wind availability.

Controlled nuclear fission Energy released from atomic nuclei

↓

Heat production Heat transferred to a working fluid

↓

Steam and turbine Thermal energy converted into mechanical energy

↓

Electricity generation Generator supplies electricity to the grid

Advantages

Provides firm, low-carbon electricity.
Can complement variable solar and wind generation.
Supports energy-intensive industries and data centres.
Can contribute to long-term energy security.

Constraints

High upfront investment and long construction periods.
Radioactive waste management requirements.
Strict safety, security and emergency preparedness needs.
Liability and public-trust concerns.

06 · Core Provisions

What Does the SHANTI Bill Propose?

Original PIB infographic showing major highlights of the SHANTI Bill 2025

Private-sector participation

The Bill permits private companies to undertake specified activities such as plant operations, power generation, equipment manufacturing and selected nuclear fuel-related activities, subject to applicable thresholds and authorisation.

Statutory recognition of AERB

It proposes statutory recognition for the Atomic Energy Regulatory Board to strengthen its regulatory authority and independence.

Graded liability framework

Operator-liability limits are linked to the type and characteristics of the nuclear installation, with limits specified in the Bill's Second Schedule.

Licensing and safety oversight

The proposed framework covers the grant, suspension and cancellation of licences and safety authorisations for nuclear energy production and use.

Peaceful non-power applications

It provides for nuclear and radiation technologies in healthcare, agriculture, industry, research and other peaceful applications.

Dispute and compensation mechanisms

The Bill provides for an Atomic Energy Redressal Advisory Council, Claims Commissioners and a Nuclear Damage Claims Commission for specified disputes and compensation matters.

Important distinction: The Bill does not propose unrestricted privatisation. The source describes specified private participation alongside licensing, safety authorisation and continued government control over sensitive activities.

07 · Institutional Architecture

How Can Participation and Sovereign Control Coexist?

The Bill's institutional design can be understood as a division between permitted commercial activity and functions reserved for the state.

Central Government Policy, strategic oversight and reserved functions

↓

Permitted private participation Specified operations, generation, manufacturing and authorised activities

Reserved sovereign functions Sensitive fuel-cycle activities, spent fuel and high-level waste management

↓

AERB and the licensing and safety framework Authorisation, safety oversight, compliance and safeguards

↓

Accountable and secure nuclear-energy expansion Public safety, energy security and strategic autonomy

08 · Technology and Innovation

Small Modular Reactors and the Nuclear Energy Mission

₹20,000 crore

Allocation announced in Union Budget 2025–26 for SMR design, development and deployment.

Targets and proposed reactor designs

2033: Target of at least five indigenously designed Small Modular Reactors becoming operational.
BSMR-200: A 200 MWe Bharat Small Modular Reactor.
SMR-55: A 55 MWe small modular reactor design.
High-temperature gas-cooled reactor: Up to 5 MWth, with hydrogen generation as an intended application.

The designs are identified in the source as initiatives associated with the Bhabha Atomic Research Centre (BARC).

Analytical significance: SMRs may offer modular deployment and new applications for industrial heat and hydrogen. Their contribution will depend on safety approvals, costs, construction performance, fuel arrangements and operational reliability.

10 · Critical Evaluation

Challenges That Require Attention

Safety and accident risk

Nuclear incidents can have severe and long-lasting consequences. Regulatory capacity, quality assurance and emergency preparedness must grow alongside capacity.

Liability and compensation

A graded liability framework needs clear rules, adequate financial protection and timely compensation without weakening accountability.

Financing and project delivery

High capital requirements, long gestation periods and construction risks can affect investment viability and the pace of deployment.

Regulatory independence

Statutory recognition must translate into adequate expertise, transparent decisions and credible enforcement.

Waste and environmental management

Safe spent-fuel handling, radioactive-waste management and long-term monitoring remain essential.

Public trust and security

Community engagement, site preparedness, safeguards and protection against security threats are necessary for durable expansion.

11 · Way Forward

A Balanced Roadmap for Nuclear Expansion

01. Strengthen independent regulation

Ensure adequate expertise, resources, transparent procedures and effective enforcement by the safety regulator.

02. Maintain clear safety boundaries

Define permitted private activities and reserved sovereign functions precisely, with strong safeguards for sensitive operations.

03. Make liability effective

Provide clear compensation procedures, adequate financial protection and accessible mechanisms for affected persons.

04. Build domestic capabilities

Develop indigenous reactor designs, skilled manpower, component manufacturing and research capacity.

05. Strengthen emergency preparedness

Improve coordination among operators, regulators, local authorities and emergency-response agencies.

06. Measure outcomes transparently

Track capacity additions, construction timelines, safety performance, waste management and project costs.

Conclusion for UPSC Mains

The SHANTI Bill represents a proposed transition towards a modernised nuclear governance framework that combines wider economic participation with continued sovereign oversight. Its success will depend not merely on installed capacity, but on whether India can deliver safe, affordable, accountable and low-carbon nuclear power while protecting public trust and strategic autonomy.
