A few words of history
In the last 20 years, COMEX NUCLEAIRE has become a key player in nuclear operations, particularly for EDF (Electricité de France – French electricity generation and distribution company).
1990: Foundation of COMEX NUCLEAIRE, stemming from the COMEX group.
1999: the ONET Group bought COMEX NUCLEAIRE and integrated it in its ONET TECHNOLOGIES division.

Supply of large components
Thanks to its exclusive cooperation with Mitsubishi Heavy Industries (MHI), COMEX NUCLEAIRE benefits from an access to the supply of large spare components:
• Calculations and analyses as per RCC-M (Règles de Conception et de Construction-Matériel mécanique -Design and construction rules for mechanical components)• Management of conformity and licensing as per ESPN (Équipements sous Pression Nucléaire - Nuclear pressureequipment) rules
• Specific engineering studies• Supervision of subcontractors• Interface with customer and installer on site

Among Comex Nucleaire contributions to Iter
Test Bench
Design of a test bench for testing the Equatorial Port Plugs, in the same conditions as in the tokamak and at different stages of the manufacturing.
Manufacture study of the ICRH plug and diagnostic plugExpertise on welding processes & sequences,Definition of the weld geometry,Distorsion analysis using Sysweld softwareMechanical analysis using Systus software
Prototype Port Plug Test Stand
Design of a prototype Port Plug Test Stand for both equatorial and upper diagnostic port plug
Televisual inspection
In service inspection for visual examination of several areas of the vacuum vessel during operations
Type B radwastes process and storage analysisFunctional analysis of the type B radwastes treatment within the hot cell,Definition of equipment and space allocation fot the treatment process and the 20 years on-site storage facility
Three+ main topics drive our interest as possible prime contractor :
�Remote handling,
�Turn key sub-systems,
�Radwaste disposal and treatment (OT).
And ?
�Engineering of the Iter licensing process ?
