What This Article Covers

1.Anil Kakodkar, former AEC Chairman, advocates early thorium introduction in PHWRs to speed up utilisation of India's abundant thorium reserves.

2.HALEU-thorium fuel can be used in PHWRs without significant design change, offering reduced spent fuel, greater economy, and uranium saving.

3.The 100 GWe nuclear mission by 2047 will likely be dominated by indigenous PHWRs, with imported LWRs occupying the remaining share.

The Big Picture
Prelims · HighMains · High

India's top nuclear scientist Anil Kakodkar urges early introduction of thorium-based fuel in India's indigenous PHWR fleet to accelerate utilisation of the world's largest thorium reserves. This strategic shift, using HALEU-thorium fuel without major design changes, aims to reduce uranium import dependency and achieve the 100 GWe nuclear mission by 2047.

Parliamentary Panel Recommends MDO Entry in Uranium Mining; India's 3-Stage Nuclear Plan to Thorium

The Parliamentary Committee on Atomic Energy has recommended allowing Mine Developer-cum-Operator (MDO) participation in uranium mining under DAE oversight to meet India's growing fuel demand for indigenous PHWRs. India currently imports uranium from Kazakhstan, Russia, Uzbekistan, and Canada, and aims to expand nuclear capacity from 8.7 GWe to 100 GWe by 2047. The three-stage nuclear program aims to transition from uranium to thorium for long-term energy self-sufficiency.

India's Space Launch Cost Highest at $13,302/kg; Study Cites ISRO's Small Rocket Fleet & Infrequent Launches

A peer-reviewed study published in Economics Letters reveals that India's per-kilogram cost to send payload to low-earth orbit is the highest among major spacefaring nations at $13,302, contradicting its reputation for low-cost launches. The high cost is attributed to ISRO's reliance on small rockets and insufficient launch frequency, preventing economies of scale.

Draft SHANTI Rules: Foreign Nuclear Tech Needs Origin-Country Approval, Operational Track Record

The DAE released draft rules under the SHANTI Act, 2025, mandating that foreign nuclear technology must have design approval from its country of origin and be operational elsewhere. The rules also introduce 'in-principle approval' for projects without a finalised site or reactor, and a single composite licence for building, owning, operating, and decommissioning nuclear plants, paving the way for private participation.

India Targets 100 GW Nuclear Capacity by 2047, 5 New Reactors This Decade for AI & Chip Demand

PM Modi announced a target of 100 GW nuclear power by 2047 and 5 new reactors this decade, driven by soaring electricity demand from AI, semiconductors, and data centres. The SHANTI Act and draft rules now enable private participation, with a focus on small modular reactors (SMRs) for faster deployment and grid flexibility.

SHANTI Act Draft Rules: Graded Nuclear Liability Caps up to ₹3,000 Cr, 5-Year Review Mechanism

The Department of Atomic Energy has released draft rules under the SHANTI Act introducing graded liability caps for nuclear operators, ranging from ₹100 crore to ₹3,000 crore based on reactor size, with a mandatory 5-year review by an expert group. This replaces the earlier flat ₹1,500 crore cap under the CLNDA 2010 and aims to attract private and foreign investment by diluting supplier liability. The Supreme Court is currently examining the adequacy of these caps and the Act's impact on compensation rights.
