Engineering enhancing nuclear safety
The Nuclear Business Unit has a dedicated Engineering Department.
The team is made up of more than 40 staff and designs specific equipment that meets nuclear safety requirements.
Sizing calculations, earthquake resistance calculations, ILS and dependability guarantee compliance with construction rules and with French and international nuclear standards.
Our teams benefit from the lessons learned over thirty years in this sector.
Industrial facilities tailored to the requirements of nuclear propulsion
CNIM Systèmes Industriels has an array of state-of-the-art machines for the manufacture of suitable equipment for nuclear propulsion:
- Our 3m - 4m diameter lathes
- Our up to 60 tonne lifting equipment
- Our testing resources
Expertise in electron beam welding, a process that allows heavy gauges to be welded without additional material and distortion, guarantees the safety and reliability of the equipment we produce.
Materials qualification
We have a dedicated materials qualification team, allowing us to offer the most suitable material for your requirements. We are also able to conduct tests allowing us to check that our equipment satisfies the various constraints imposed by the customer.
Our achievements
Reactor cover handling equipment
CNIM Systèmes Industriels has supplied lifting equipment on behalf of FRAMATOME for Hinkley Point, the new generation EPR type nuclear plant built by EDF ENERGY in the United Kingdom. This lifting equipment for the reactor cover (Reactor Pressure Vessel Head Lifting Device) allows inspection and maintenance operations, as well as nuclear reactor unit shutdowns, to be performed. This equipment meets stringent safety requirements and must be able to withstand earthquakes.
CNIM Systèmes Industriels handled the procurement, manufacture-to-plan, load and factory testing and delivery of mechanical assemblies in accordance with standards EN 1090-2 and EXC 3&4.
Lifting equipment during manufacturing in our workshops
Transfer equipment
The TPTS transfer system is equipment designed to transfer components to the ITER tokamak vacuum chamber through its very narrow doors.
This system comprises a support gantry for “standard” hoists and trolleys, which allows equipment to be passed through the doors and tilted.
It guarantees safe, stable operation during transfers and complies with FEM standards.
Our teams have developed a simulation test bench for this equipment, in order to qualify it.
Handling equipment
Our teams have designed and produced vital handling equipment for the LMJ to support operation and maintenance of the experimental hall. This assembly primarily comprises remotely operated systems with the main one being the Experimental Hall Intervention System (SIHE). This includes a manned autonomous vehicle and a range of equipment: cylinders, trolleys and pusher chain on rails that follow complex paths.
