Committing India to dedicated HALEU production is not yet warranted on demand grounds. Foreclosing the option, whether through enrichment capacity designed without margin or through a safeguards determination taken by default rather than deliberately, could however require a decade or more to reverse.

The investment approvals and fuel-cycle decisions before the Government of India will determine whether India’s advanced-reactor ambitions of the 2040s are fuelled at all. Indian discussion of high-assay low-enriched uranium (HALEU), uranium enriched above 5 and below 20 per cent U-235 and the enabling fuel for a majority of advanced reactor designs under development worldwide, has nonetheless settled into a procurement framing.

The question is posed as one of access: which non-Russian producers are dependable, what offtake terms are achievable, and how soon agreements can be concluded. That framing misdirects attention towards negotiations that may not deliver on India’s timetable, while deferring industrial decisions whose lead times can run to a decade or more. HALEU scarcity is not a market condition India can contract around. It is an industrial-capacity condition, and India’s response must preserve the ability to build rather than assume it can buy.

What India Has, and What It Lacks

India’s position is unusual and frequently misread. It is neither a newcomer nor a state that can purchase its way into the advanced fuel cycle. India possesses centrifuge competence, developed principally for strategic purposes, and a fuel-cycle industrial base covering conversion, fabrication and reprocessing that is deeper than that of almost any state outside the original nuclear suppliers. It also possesses a stated civil rationale for enrichment independent of HALEU. The Special Material Enrichment Facility at Chitradurga has been publicly framed for civilian applications, with slightly enriched uranium intended to raise burn-up in India’s pressurised heavy water reactors.[i]

What India lacks is civil-scale capacity, and the distinction is not semantic. Enrichment for strategic requirements and enrichment for a commercial reactor fleet differ by orders of magnitude in separative work. Beyond the cascade, HALEU requires deconversion capability, fabrication lines matched to specific advanced-reactor fuel chemistries, and transport containers certified against a materially different criticality envelope. None of these is a marginal extension of existing pressurised heavy water reactor fuel work.

The legal architecture compounds rather than relieves this. The SHANTI Act, 2025 opens the construction, ownership and operation of nuclear power plants to private and joint-venture participation under licence, but reserves enrichment and other core fuel-cycle functions to the state unless otherwise notified; it also permits selected private fuel-cycle activities up to thresholds set by government.[ii]

The implication for HALEU is direct and insufficiently discussed: the private capital unlocked for reactor projects cannot automatically own or finance the enrichment bottleneck. Direct enrichment investment must still be sanctioned and anchored by the state, although private suppliers can participate in manufacturing, construction and services. Fuel-cycle capacity therefore remains a sovereign investment decision even as reactor capacity is opened to the market. Meanwhile, the Atomic Energy Regulatory Board, which the Act finally endows with statutory recognition, would need to develop safety cases, licence facilities, and certify transport packages for a much larger criticality envelope.

Nor is Indian demand yet established. The indigenous roadmap points towards thorium utilisation and fast reactors, while the lead small modular reactor designs are to operate on slightly enriched uranium within the existing architecture.[iii] The high-temperature gas-cooled reactor being developed for hydrogen production is the indigenous design most likely to create demand in the HALEU band. However, its final fuel requirement has not been established publicly. Imported or collaborative advanced designs would bring their own requirements. The demand case is therefore real but contingent, which is an argument for preserving optionality cheaply rather than committing to either option.

Safeguards Is the First Gating Decision

The first consequential choice is not technical. India’s enrichment competence resides on the unsafeguarded side of the separation plan, while Chitradurga has been publicly framed for civilian applications. Placing future HALEU-capable civil capacity under safeguards determines what forms of foreign partnership, downstream cooperation and eventual export participation are even feasible. It is necessary but not sufficient.

Nuclear Suppliers Group guidelines impose separate restrictions on transfers of enrichment facilities, equipment and enabling technology, including criteria India does not presently meet as a state outside the Nuclear Non-Proliferation Treaty (NPT). Safeguards could facilitate cooperation in non-sensitive components,........
