Reactor Grade Uranium Price — June 5, 2026

Reactor grade: a specification wearing a price question

The searchable half of the answer: reactor grade uranium's feed basis trades at ₹16.57 per gram today, June 5, 2026. The unsearchable half: "reactor grade" names a specification, not a product on any shelf — low-enriched uranium at 3–5% U-235 for the world's light-water fleet, chemically pure natural uranium for India's PHWRs, custom-made in both cases under contracts that publish nothing. This page prices what can be priced and specifies the rest.

The grade ladder, located:

• Natural uranium (0.7% U-235): the priced benchmark — and India's PHWR grade
• LEU / reactor grade (3–5%): the world fleet's standard, contract-priced
• HALEU (5–20%): the SMR era's emerging grade, scarcity-priced
• Beyond 20%: outside civil commerce entirely, safeguards territory

Every rung above the first prices privately; every rung's economics anchor to the first. The benchmark on this page is reactor grade's public shadow.

Constructing the grade's cost

A kilogram of 4.5%-enriched reactor grade embeds, roughly: 8–10 kg of natural feed (the benchmark × the mass), conversion services on that feed, and the SWU bill of concentrating the isotope — historically the construction's heaviest line. Specifications add their own economics: ASTM purity limits on the feed, exacting isotopic tolerances on the product, qualification programmes binding each fuel design to each reactor. The grade is as much paperwork as physics, and both cost.

India's grade shortcut, revisited

The Bhabha-era PHWR choice gave India a structural grade advantage: natural uranium is reactor grade for the indigenous fleet, deleting the SWU line from the construction entirely. The trade — heavier feed use, heavy-water systems — bought enrichment independence decades before the NSG waiver made imports possible. Kudankulam's VVERs reintroduced LEU to India's grade portfolio via Russian supply; the SMR programme may add HALEU. Three grades, one national fuel strategy, all anchored to the feed number above.

The grade ladder's top rungs carry the page's mandatory clarity: reactor grade and weapons material are separated by an industrial chasm — 3–5% versus ~90% enrichment — that no civil facility crosses and every safeguard watches. Reactor grade uranium cannot explode; the physics is settled and the distinction is the non-proliferation order's bedrock. Price pages owe readers that sentence as much as any number.

HALEU: the grade to watch

The emerging story sits mid-ladder: HALEU, the 5–20% grade most advanced reactor designs specify, with Western production capacity only now building and demand projections steepening. Every HALEU kilogram embeds more feed and more SWU than conventional grade — meaning the SMR era, if it arrives on schedule, amplifies demand for exactly the benchmark this page tracks daily. Grade economics, again, flowing downhill to the feed.

Using the grade lens on the daily number

The construction maths converts this page's benchmark into grade-cost movements automatically: feed up ten percent means reactor grade's largest input up ten percent, with SWU markets deciding how much reaches delivered-fuel costs. Enrichment-capacity news — expansions, the post-2022 realignment, HALEU awards — modulates the multiplier. Two public signals, one private price, fully bracketed.

For investors, the grade lens sorts the fuel chain's equities: miners sell the feed (this page's direct trackers), enrichers sell the grade-making (SWU-cycle businesses), fabricators sell the final qualification (engineering economics). Knowing the rung explains the stock — and the daily anchor above explains the rung.

The feed basis refreshes tomorrow; the grades keep constructing above it. Specification and price, daily reconciled here.
