Milei Is Selling Off Argentina’s Nuclear Crown Jewels, and Critics Are Alarmed

Energy

President Javier Milei is throwing open Argentina’s Argentina nuclear sector to private and foreign money. Investors see opportunity; scientists and unions see a fire sale of assets the country spent seventy-five years building.

The government frames it as modernization. It says private capital will fund reactors the cash-strapped state cannot afford, extend the life of existing plants and revive uranium mining.

What the Argentina nuclear sell-off involves

The centerpiece is the utility. The state plans to sell forty-four percent of Nucleoeléctrica, which runs the country’s three reactors, keeping a controlling stake while inviting private partners in.

The reach goes wider. The atomic energy commission has opened a process letting private parties, local or foreign, inspect and bid for a range of once-untouchable state nuclear assets.

The rationale is fiscal. Nucleoeléctrica runs a large deficit, and Milei’s team argues that private money and management will cut costs and finance the projects the treasury simply cannot afford.

The CAREM casualty

One project has become a symbol. CAREM, a small modular reactor designed entirely with Argentine technology, was among the most advanced of its kind anywhere, according to the United Nations nuclear watchdog.

It was nearly finished. Its civil works were about eighty-five percent complete, with more than four hundred million dollars already spent, when the Milei government halted it and declared it unviable.

In hard terms, more than $400m had gone in. Walking away from a project that far along strikes critics as waste, though the government counters that finishing it would cost far more still.

The plan now favors foreign designs. In place of the domestic reactor, officials talk of installing modular units based on other patents, still at the design stage and years from delivery.

Critics see the choice as telling. Stopping an almost-built national reactor while courting foreign designs, they argue, trades hard-won know-how for dependence on outside suppliers.

A turn toward Washington

The pivot is geopolitical. Argentina has joined a United States-led nuclear technology program and signed a deal on uranium supply, drawing its atomic future closer to Washington.

American interest is concrete. United States officials have toured Argentine nuclear sites, and American-linked firms have proposed private reactors and uranium projects worth hundreds of millions of dollars.

It has ruffled old partners. The shift has cooled earlier talks with China, which had offered financing for a new plant and a large currency backstop.

The realignment fits a wider pattern. Milei has tied Argentina closely to Washington across trade, finance and defense, and the nuclear turn is one more strand of that embrace.

Why it matters beyond Argentina

For an investor, the appeal is clear. Small modular reactors are a coming technology, and demand from power-hungry data centers has made clean, steady electricity a prized commodity.

The risks sit alongside it. Scientists and unions warn of resignations and a brain drain, saying the sector’s value lies in expertise that is far harder to rebuild than to sell.

The debate is really about sovereignty. Argentina is one of only a handful of nations that masters this technology, and the fight is over whether that edge is an asset to keep or a business to sell.

There is a regional dimension too. Brazil is pursuing its own nuclear and submarine ambitions, so what Argentina does with its expertise shapes the balance of technical know-how across South America.

Argentina also exports its skills. Its state technology firm has long sold research reactors abroad, a niche business that rests on exactly the public capabilities now up for debate.

For a foreign observer, it is a test case. It shows a government betting that private capital can do what the state no longer will, and asking a country to weigh efficiency against independence.

Frequently Asked Questions

What is happening to Argentina nuclear power under Milei?

Argentina is opening its state nuclear sector to private and foreign capital, including selling forty-four percent of the utility Nucleoeléctrica. At the same time it has halted the home-grown CAREM reactor and aligned more closely with the United States.

Why is the CAREM reactor controversial?

CAREM was an Argentine-designed small modular reactor, about eighty-five percent built with over four hundred million dollars spent, rated among the world’s most advanced. Halting it while courting foreign designs has fueled fears of lost technological sovereignty.

Why does Argentina nuclear policy matter to investors?

Small modular reactors and uranium are strategic assets in demand for clean power and data centers, and Argentina’s opening could draw significant foreign capital. But brain drain, political resistance and sovereignty concerns add real risk to the bet.
