Corruption allegations and judicial complaints targeting Demian Reidel’s leadership at Nucleoeléctrica Argentina SA (NA-SA) have escalated into a significant governance crisis within the state nuclear sector. These disputes expose deep weaknesses in internal controls and procurement integrity, threatening operational stability in strategic nuclear facilities. Market watchers should monitor potential implications for nuclear sector contracts and government oversight as tensions intensify.
Demian Reidel, appointed president of NA-SA in April 2025 and a close adviser to President Javier Milei, is facing multiple allegations involving irregularities in critical procurement processes. The focal point is a tender for cleaning services at the radiologically sensitive Atucha I and II nuclear plants, where complaints center on overpricing and manipulated bidding procedures. LX Argentina’s winning bid was reportedly 140% higher than previous contracts, raising concerns over inflated costs and financial harm to the company. Internal whistleblower Juan Pablo Nolasco Sáenz, a plant manager, filed detailed submissions to the company’s Integrity Committee describing pressure to revise technical evaluations and artificially justify inflated bids, as well as inappropriate interventions by departments without direct technical remit. Following these revelations, the NA-SA board removed two of Reidel’s appointees, general manager Marcelo Famá and administrative coordinator Hernán Pantuso, signaling significant leadership discord.
Further legal challenges precede the Atucha cleaning tender controversy. Distribón SRL, another service provider, lodged a federal court complaint alleging bid-rigging through arbitrary admissibility criteria and unfeasible deadlines, accusing NA-SA of deliberately favoring certain bidders. The tender requirements—such as inflated staffing levels and technical certifications unrelated to contract scope—have been contested, with the courts withholding injunctions but leaving underlying legality open.
Additional procurement disputes have surfaced, notably around a technology contract to migrate NA-SA’s SAP system, where costs allegedly ballooned from US$600,000 to US$7 million without transparent justification or audit trails. The state workers’ union ATE has formally cited this as evidence of systemic lapses in internal controls under Reidel’s leadership. Both Reidel and NA-SA have declined to comment publicly on these allegations.
These procurement controversies unfold against a backdrop of heightened political sensitivity surrounding President Milei’s administration and its ideological influence over strategic sectors, heightening risks for investor confidence and government contract governance in Argentina’s nuclear and broader energy industries.
