A partner throughout the life cycle of nuclear facilities

Onet Technologies is a partner to players in the nuclear industry, supporting them in their day-to-day needs or in projects requiring a high level of engineering. Our expertise has been recognized for over 40 years for its quality of service and technical expertise, as well as for its high level of safety and security requirements.

 

Onet Technologies, as a member of GIFEN (the French nuclear industry association), supports the implementation of the industry's Excell plan. Our company is committed to industrial quality in the nuclear industry. Whether it's through the development of qualifications, traceability, compliance, or in certain major modification and welding projects, we want to support the industry to regain the level of rigor, quality and excellence in France and internationally.

Onet Technologies is convinced that the nuclear industry as a whole can play a major role in the energy transition and the reduction of greenhouse gases. Working on French and international facilities for 40 years, our company supports the major players in the nuclear industry throughout the entire life cycle of their installations (from design to decommissioning). Our company has engineering and intervention capabilities. Safety and security culture, skills management and operational performance are at the heart of our nuclear services.

The nuclear safety and security standards set by the ASN and international nuclear safety authorities represent a major challenge for all players in the sector. Our teams are trained to master these standards at every stage of the project process, from design to operational implementation. Onet Technologies also holds a large number of certifications and qualifications that guarantee quality, reliability, impartiality and confidentiality. Our Quality, Health, Safety, Security, Environment and Radiation Protection team is the guarantor of these stakes, and integrates them into the heart of everyone's activities.

Most of the nuclear facilities we work on were designed to be operational for 30 years. Today, we are working with operators to extend the lifespan of these facilities in line with current safety and security standards. For example, Onet Technologies has already worked with EDF on the 4th ten-yearly inspection of several nuclear power plants.

The safety of installations and people is at the heart of our business. In addition to dedicating an operational team to these issues, Onet Technologies has made safety its top priority. Our collective objective is "Zero accidents". This ambitious objective requires the mobilization of all our employees, from management to operators. Teams are made aware of this on a daily basis. Each team member is responsible for communicating risk situations and implementing solutions to resolve them.

"At Onet Technologies, personal safety is a top priority. From the operators who work on a daily basis, to the senior management who regularly visit our customers' sites."

Our vision of nuclear engineering and services services

Supporting players in the industrial and nuclear sectors also means sharing challenges and convictions. Today, we are convinced that nuclear power has a role to play in the fight against global warming. By producing energy with low CO2 emissions, the nuclear industry is essential to meeting our society's growing energy needs. To achieve this, the industry faces a major challenge: that of ensuring the excellence, performance and lifespan of nuclear facilities. Our main mission is to support our customers in meeting these challenges. Every day, Onet Technologies employees work alongside our customers to shape the nuclear industry of tomorrow. Performance, innovation, safety and security are at the heart of everything we do.
