Members of Argentina’s Association of State Workers (ATE) are up in arms over a surprise development on August 6. Professionals associated with the CAREM nuclear reactor are bemoaning the removal of a project-related supplement on their payslips, lowering some incomes by up to 30% without prior notice. The union is planning to challenge the measure in court.
The dispute reaches far beyond one line on a pay stub. CAREM is Argentina’s homegrown small modular reactor prototype, a project that remains protected by national law even as construction sits suspended and President Javier Milei’s government promotes a separate privately financed reactor proposal at the same Atucha nuclear complex.
Can Argentina preserve its nuclear expertise while changing who pays for the next generation of reactors?
Pay cut lands without warning
ATE said the removed “CAREM Strategic Project” supplement affected workers at CNEA facilities in Bariloche, Ezeiza, and the Constituyentes Atomic Center. It also alleged that the measure fell disproportionately on employees who had recently joined a protest against the agency’s leadership, although that retaliation claim has not been independently established.
The union said it will seek judicial review because no known objective criteria or administrative act had been provided to justify the decision. The conflict also follows Decree 655/2026, issued on July 24, which described CNEA’s 645-unit organization as oversized and ordered a new structure, including a lower-level plan to be submitted within 60 days.
CAREM is paused, not legally erased
CAREM has not vanished from Argentina’s legal framework. Law 26,566 declared the project to be in the national interest and assigned CNEA responsibility for its design, execution, and startup, while CNEA’s current website still presents the prototype as an Argentine-designed technology under the commission’s responsibility.
That legal status does not mean construction is moving. ATE places overall progress near 70% after an estimated $690 million in public investment, while EconoJournal reported 63% physical completion at the end of 2024 and said work ceased in early 2025.
The public material reviewed does not provide a common method that would reconcile those figures, but the practical conclusion is the same. The reactor remains unfinished and suspended.
The real asset is the team
Concrete and steel matter, but a nuclear program is also stored in people’s heads. CNEA says Argentina has domestic capabilities in modular design, thermal hydraulics, passive safety, fuel design, instrumentation, and control, while international industry reporting says roughly 70% of CAREM components were intended to be manufactured locally.
That is why the salary dispute carries a technical risk as well as a labor one. ATE-CNEA delegate Daniel Sanchez warned that losing specialists could eventually halt work such as producing uranium fuel pellets for the SMR, although that forecast has not been independently verified. EconoJournal has separately reported professional departures and minimal preservation work at the site.
Once an experienced team scatters, rebuilding it is rarely as simple as hiring the same number of people.
A private reactor changes the equation
The government is meanwhile promoting a different model. In July, it announced that Meitner Energy proposed investing $1.2 billion in a privately financed 300-megawatt ACR-300 reactor at Atucha, with a projection of 2,000 direct jobs across development, construction, commissioning, and operations. The plan remains a proposal and depends on legislation and nuclear licensing before construction can begin.
In presenting the project, the government rejected claims that it was hollowing out the nuclear sector. Its stated doctrine is that the state should set priorities and regulate while private capital invests, and it argued that private expansion would retain talent and improve pay over time. That defense was issued on July 7, one month before ATE’s salary complaint, so it does not explain the specific removal of the CAREM supplement.
CNEA workers quoted in the reporting see a different pattern. They believe public expertise is being weakened while a private reactor venture advances, but the records reviewed do not establish that the CAREM salary supplement was removed to benefit Meitner Energy. Keeping those two points separate matters. The timing raises a legitimate policy question, not proof of a coordinated transfer.
What happens next
The next evidence will come from documents rather than speeches. ATE’s promised court action could force disclosure of the legal basis and selection criteria for the pay decision, while CNEA’s new organization chart should show whether CAREM retains budget authority, preservation staff, and a clear technical mandate. Meitner’s proposal will face its own tests, including legislative incentives and nuclear licensing.
For now, CAREM occupies an uneasy middle ground. It remains a nationally mandated project and an official showcase of Argentine engineering, yet a reactor can be sidelined without formal cancellation if its funding, leadership, and specialist workforce steadily disappear. For now, Argentina is deciding whether CAREM will remain a working prototype or become a costly unfinished asset as its expertise moves elsewhere.
