TECNA’s experience in the nuclear field began in late 1970s. By that time, TECNA participated in the engineering for research and radioisotope-production reactors: RA-6 in Bariloche, Argentina; RP-10 in Huarangal, Peru; and NUR in Algeria.
Since 2008, TECNA has an important participation in the design and construction of nuclear power plants, by supplying engineering services, supervision of mechanical erection and assistance to commissioning and start-up.
TECNA is a contractor to Nucleoeléctrica Argentina S.A (NA-SA) in the completion of the Atucha II Nuclear Power Plant (PHWR, 694 MWe-net). TECNA has provided services for many systems of the plant, including engineering for piping, supports and stress analysis, electrical and process engineering, specialized services for start-up as well as studies for licensing, safety and core design. In addition, TECNA has supplied a complete radiation-in-air monitoring system, which includes a fiber optics network in the reactor and auxiliary building and data acquisition, analysis and alarm systems. TECNA has received thereafter a qualification from NASA to perform engineering services, supervision of mechanical erection and assistance to commissioning and start-up of systems rated quality-class I to IV in nuclear power plants.
In addition, TECNA has supplied engineering services for the Atucha I NPP (PHWR, 335 MWe-net) and Embalse NPP (Candu PHWR, 600 MWe-net). These works included participation in the “post-Fukushima” seismic re-evaluation program for the Atucha I NPP.
