The Unión por la Patria bloc in the national Chamber of Deputies rejected the national government's decision to move toward a new nuclear development scheme involving private participation.
The bloc argues that this direction is being taken while the CAREM project remains paralysed, the National Atomic Energy Commission is underfunded and strategic capacities built over decades by the Argentine state are being weakened.
For the opposition space, the executive branch's announcement represents a paradigm shift in a policy area considered central to the country's scientific, technological and industrial development.
The concern also extends to workers in the nuclear sector. The bloc warned about dismissals of highly qualified personnel and the risk of losing knowledge accumulated in public agencies and companies.
The parliamentary initiative requests detailed information from the national government about Meitner Energy, the corporate structure of the venture and ownership of the intellectual property linked to the new projects.
It also seeks clarity on the planned tax benefits, the future of Nucleoeléctrica Argentina, Dioxitek and CAREM, and the reasons for recent dismissals at the National Atomic Energy Commission.
Unión por la Patria said nuclear energy must be treated as a strategic policy rather than an area subordinated to private or mostly foreign interests.
The bloc clarified that it does not reject private investment itself, but argued that any investment process must preserve technological sovereignty, Argentine intellectual property, public companies and employment continuity for specialised workers.
