The ONET Group, specialist in industrial cleaning, created SOGEDEC in 1978 to meet the needs of its clients in the nuclear field in the specific areas of decontamination and decommissioning.

The level of recruitment and the organisation in place mean we can guarantee the quality and technical content of our service performance.

Our first establishment in La Hague was to be rapidly completed by agencies in Marcoule and then Paris.

Our know-how, constantly enriched by feedback means we have been able to:

• decommission, in 1985, the dissolvers of the COGEMA Marcoule fuel reprocessing factory,
• export, at the end of the 1980s, our expertise in glove-box works in a plutonium environment to the German site of Hanau,
• establish ourselves in 1991 in the ISPRA European Research Centre to become the key player in the denuclearisation of the site.
  
  In parallel with its services in the nuclear industry, SOGEDEC has diversified into other risk sectors, such as asbestos. In 1987, SOGEDEC was awarded the 'Classified Installation Prize' by the French Environment Minister for the treatment of a disused factory polluted by asbestos.
  
  SOGEDEC's development goes hand in hand with the life of nuclear installations. Our first ever clients were CEA and AREVA.
  
  The French leader in nuclear decommissioning, SOGEDEC is also well placed with EDF with the rise in decommissioning of the first power stations in the graphite gas and pressurised water sectors.
  
  Completing the range of its integrated solutions, SOGEDEC has its own CEPI (Classified Environmental Preservation Installation) dedicated to the storing and manipulation of radioactive substances (materials and waste).
