Supply of pre-compression rings for the ITER magnet system. These pre-compression rings shall be made of pultruded laminates long enough to produce a complete ring. During the qualification phase, the composite shall be first characterised to prove that the material requirements are achieved. Three 1/5 scale mock-up and a full-scale slice rings shall be provided as part of the qualification phase. Based on the accepted qualification phase, 3 pre-compression rings shall be produced and delivered to Fusion for Energy.
