## Is Korea Cutting Its Dependence on Russian Enriched Uranium Through the Orano Deal?

[Korea Hydro & Nuclear Power](https://smrintel.com/companies/khnp) has taken a direct step toward reducing its exposure to Russian [uranium enrichment](https://smrintel.com/glossary/enrichment) services, signing a letter of intent with France's [Orano](https://smrintel.com/companies/orano) on September 9, 2026, at the Élysée Palace in Paris — with the presidents of both South Korea and France present at the signing. The LOI commits both companies to long-term cooperation in uranium enrichment, building on an MOU the two signed in April 2026. Russia currently supplies approximately 30 percent of South Korea's enriched uranium imports, according to the source. Korea imports all of its enriched uranium, with no domestic enrichment capability permitted under its nuclear cooperation agreement with the United States. KHNP President Kim Hoe-chun stated the agreement would "expand cooperation between the two companies and further strengthen the stability of our nuclear fuel supply." For the global nuclear fuel market, this deal signals that Western enrichers — Orano in particular — are actively positioning to absorb demand that has historically flowed to [Rosatom State Nuclear Energy Corporation](https://smrintel.com/companies/rosatom) and its affiliates.

## Why Korea Cannot Enrich Its Own Uranium

The structural driver behind this deal is a legal one, not a technical one. South Korea is prohibited from enriching uranium domestically under its 123 Agreement with the United States — the bilateral nuclear cooperation framework governing civilian nuclear activities. This constraint forces Korea, despite operating one of the world's largest and most efficient reactor fleets, to source all enriched uranium on the open market.

That dependency has concentrated risk. Roughly 30 percent of Korea's enriched uranium has come from Russian suppliers — a supply chain that carries obvious geopolitical exposure post-2022. Diversification into Western enrichers is not merely a commercial preference at this point; it is a strategic necessity that Korean energy security planners have been pushing for.

The Orano LOI is the latest instrument in that effort. An LOI is a preliminary document expressing intent to cooperate, positioned before a full MOU or commercial contract. The April 2026 MOU between KHNP and Orano had already established the framework; the Élysée signing upgrades the political visibility of the relationship and signals that long-term enrichment supply agreements — likely multi-decade, given the capital planning horizons of nuclear fuel procurement — are in active negotiation.

## What Orano Gains From the Partnership

For Orano, this is straightforward commercial positioning. The French enricher operates the Georges Besse II centrifuge enrichment plant at Tricastin, one of the largest enrichment facilities in the Western world. As utilities globally work to reduce their Rosatom exposure, Orano faces structurally increased demand for its enrichment services — but long-term contracts are required to justify any capacity expansion.

Securing a committed Korean offtake partner through an escalating agreement structure (MOU in April, LOI in September, commercial contracts presumably to follow) gives Orano the demand signal it needs to underpin new enrichment project investments. The source notes that Orano is "expected to establish a foundation for long-term cooperation and strengthen its business base for new enriched uranium projects" — language that suggests capital investment decisions are tied to deals of this type.

The Élysée setting is also notable. Conducting the signing at the French presidential palace, with both heads of state present, elevates this from a routine commercial transaction to a state-backed energy security commitment. That level of political cover matters for the kind of long-duration, billion-dollar enrichment contracts that nuclear fuel procurement involves.

## Broader Industry Implications

Korea's situation is a compressed version of a problem facing nuclear utilities across Europe, Japan, and the United States: over-reliance on Russian enrichment services built up over decades when geopolitical risk was underpriced. The KHNP-Orano progression from MOU to LOI — with commercial agreements presumably next — illustrates the procurement sequencing utilities use to formalize supply diversification.

[Urenco](https://smrintel.com/companies/urenco) and [Centrus Energy Corp](https://smrintel.com/companies/centrus-energy) are the other major Western enrichers who stand to benefit from the same structural shift. Whether Orano locks in Korean volumes on terms that meaningfully displace Russian supply — or whether Russia retains a portion of that 30 percent share through pricing advantages — depends on commercial negotiations not yet disclosed.

The deal also matters for the SMR context. As Korea advances its APR+ program and evaluates SMR deployments for both domestic use and export, securing a reliable Western enrichment supply chain is prerequisite infrastructure. SMR fuel contracts, while not the subject of this LOI, ultimately depend on the same enrichment capacity being locked in at the utility level.

One caveat worth flagging: an LOI is non-binding. The April MOU was itself a step removed from a commercial contract. Observers should watch for whether a formal long-term enrichment supply agreement — with volume commitments, pricing structures, and delivery schedules — follows within a reasonable timeframe. The political theater of an Élysée signing creates momentum, but the nuclear fuel market runs on signed contracts, not communiqués.

## Key Takeaways

- **KHNP and Orano signed an LOI on September 9, 2026**, at the Élysée Palace, with Korean and French presidents attending, for long-term cooperation in uranium enrichment.
- **Russia supplies approximately 30 percent** of South Korea's enriched uranium imports — the supply concentration this deal is designed to reduce.
- **Korea imports 100 percent of its enriched uranium** due to U.S.-Korea nuclear cooperation agreement restrictions on domestic enrichment.
- **An April 2026 MOU** between KHNP and Orano preceded this LOI, indicating an escalating commercial and political commitment.
- **Orano's strategic interest** lies in securing Korean demand signals to underpin investment in new enrichment capacity, as Western enrichers compete to replace Rosatom's market share globally.
- **The LOI is non-binding** — a commercial supply contract with volume and pricing terms is the next threshold that will determine real supply chain impact.

## Frequently Asked Questions

**Why does South Korea need to import all of its enriched uranium?**
Under its 123 Agreement — the bilateral nuclear cooperation framework with the United States — South Korea is not permitted to enrich uranium domestically. This applies regardless of South Korea's technical capability and forces the country to procure all enriched uranium on the international market.

**What share of South Korea's enriched uranium comes from Russia?**
According to the source reporting on this deal, Russian suppliers account for approximately 30 percent of South Korea's total enriched uranium imports.

**What is the difference between the April MOU and the September LOI?**
A letter of intent (LOI) is a preliminary document that precedes an MOU and expresses the parties' intent to cooperate at a conceptual level. In this case, the April MOU had already established a cooperation framework; the September LOI appears to deepen the commitment specifically around uranium enrichment and long-term supply, suggesting commercial contract negotiations are progressing.

**What does this deal mean for Orano's enrichment business?**
Orano stands to secure a long-term Korean demand commitment that could justify investment in new enrichment projects. As global nuclear utilities reduce their Rosatom exposure, Western enrichers including Orano face structurally higher demand — but long-term offtake agreements are required before capacity investments can be sanctioned.

**How does the KHNP-Orano LOI affect the global enrichment market?**
It reinforces the post-2022 trend of utilities actively shifting enrichment procurement away from Russian suppliers toward Western alternatives including Orano, Urenco, and Centrus. Each deal of this type tightens available Western enrichment capacity and increases competitive pressure on pricing for other buyers in the queue.
