The budget has delivered a strong push to India’s nuclear research ecosystem, nearly doubling allocations for research and development (R&D) under the Department of Atomic Energy (DAE). The government has earmarked ₹2,410.48 crore for nuclear research projects this year, up sharply from ₹1,284.77 crore in the revised estimates of 2025–26—an 88% increase. The higher outlay signals a renewed focus on strengthening indigenous reactor technologies and advanced nuclear innovation.
Capital Spending Takes Centre Stage
Importantly, the Budget has prioritised capital expenditure over revenue spending, indicating a focus on infrastructure creation and long-term asset building.
*Capital expenditure: ₹1,977.20 crore (vs ₹928.95 crore) — up 113%
*Revenue expenditure: ₹433.38 crore (vs ₹355.82 crore) — modest increase
The shift suggests that the government is accelerating investments in equipment, facilities, and core research capabilities rather than routine operational costs.
BARC Gets the Biggest Boost
The Bhabha Atomic Research Centre (BARC), India’s premier nuclear research institution, has emerged as the largest beneficiary of the enhanced funding. The finance ministry has increased BARC’s capital support for R&D projects to ₹1,609.16 crore, compared with ₹778.37 crore last year. Notably, the original 2025–26 allocation stood at ₹880.54 crore, indicating that BARC had underspent part of its earlier outlay.
Overall:
*Total allocation to BARC (capital + revenue): ₹1,800 crore
*Previous revised estimate: ₹918.91 crore
*Increase: 95%
The higher allocation aligns with BARC’s mandate to develop next-generation nuclear technologies, including:
*200 MW Bharat Small Modular Reactor (BSMR-200)
*55 MW Small Modular Reactor (SMR-55)
*5 MW (thermal) high-temperature gas-cooled reactor for hydrogen production
However, the Budget documents stop short of explicitly linking the funds to these specific projects.
Bonanza for IGCAR’s Fast Breeder Programme
Meanwhile, the Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam, has also received a substantial funding jump.
Support for its R&D projects has risen sharply:
*Total allocation: ₹226 crore (vs ₹67.86 crore earlier)
*Capital expenditure: ₹183.82 crore (vs ₹59.79 crore)
*Revenue expenditure: ₹42.18 crore (vs ₹17.07 crore)
According to the DAE’s demand notes, IGCAR leads the design and development of liquid sodium-cooled fast breeder reactors, a key part of Stage II of India’s nuclear power programme. These reactors aim to enhance fuel efficiency through fabrication and reprocessing technologies. The higher outlay could accelerate progress in advanced breeder reactor capabilities.
Overall DAE Allocation Stays Flat
Despite the sharp rise in R&D allocations, the total budgetary support to the Department of Atomic Energy has slightly declined.
*Total DAE allocation: ₹24,123.92 crore
*Previous revised estimate: ₹24,411.47 crore
The marginal dip reflects reduced capital support to power generation rather than research.
Lower Support for NPCIL as Finances Improve
The decline primarily stems from a cut in capital assistance to the Nuclear Power Corporation of India Ltd (NPCIL).
*NPCIL capital allocation: ₹5,500 crore
*Previous year (RE): ₹8,242 crore
The reduction appears linked to NPCIL’s stronger financial position. According to Acuité Ratings & Research:
*Operating income: ₹20,384.66 crore (2024–25)
*Net profit: ₹4,737 crore
*Net worth increased to ₹67,033 crore from ₹61,605 crore
Financial risk profile described as “healthy”. Given its improving balance sheet, NPCIL may require less direct budgetary support.
Outlook: Research-Led Nuclear Strategy
As reported by thehindubusinessline.com, taken together, Budget 2026 marks a clear strategic shift toward research-led nuclear growth. While overall departmental spending remains steady, the government has channelled significantly higher funds into advanced reactors, small modular reactors (SMRs), hydrogen-linked technologies, and fast breeder systems. As India works to expand clean energy capacity and strengthen energy security, these investments could accelerate the development of next-generation nuclear technologies and domestic innovation.
