Nuclear Fuel Element Production

Pioneers in Nuclear Fuel Solutions for Critical Reactors

Since 1982, CONUAR has been a pioneer in the design and manufacturing of nuclear fuel elements, offering safe and reliable solutions for a wide range of reactor types, including: PWR, PHWR, MTR and SMR.

With over 40 years of experience in the nuclear sector, we produce 100% of the nuclear fuel used in Argentina’s power plants.

Capabilities

Uranium Pellet Manufacturing

Production of uranium dioxide pellets using Natural Uranium (NU), Slightly Enriched Uranium (SEU) at 0.85%, and Enriched Uranium (EU) with enrichment levels up to 5%.

Fuel Assembly Fabrication

Precision assembly of nuclear fuel elements to meet the operational requirements of various reactor types. This includes plate-type configurations for MTR reactors (LEU 20%).

Reactivity Control Rod Manufacturing

Production of control rods using materials such as Cobalt-60 (Co-60) and Hafnium (Hf), essential for regulating neutron flux within the reactor core and for gamma source generation.

Inspection and Quality Control
