The International Experimental Thermonuclear Reactor Iter is an experimental project to verify the scientific and technical feasibility of nuclear fusion as a new energy source. The project currently under construction in Cadarache involves thirty-five countries. The operational phase is expected to begin in 2020. In France, only The Emitech laboratories, which offer a pool of skills and testing facilities, have obtained the Cofrac accreditation necessary to test future equipment.
The first trials began in 2014. The Lyon centre, whose staff is authorized to work in the nuclear environment (DATR B) has already responded to a series of electromagnetic compatibility tests, in particular on immunity to static magnetic fields, specific to Iter.
The tests focus on the ITER 98JL4W specification: the tested material must continue to function normally when subjected to one of the 5 levels of magnetic fields (following its distance from the core) from 7.5 mT to 120 mT defined by the specifications.
Emitech is equipped with square-section induction coils that generate a 100 mT magnetic field for 5 minutes every 30 minutes.
Other laboratories in the group already have earthquake test benches in place "together" and "components": the test subjects the materials to simultaneous horizontal and vertical excitement. The maximum displacement should not exceed 250 mm horizontally and 100 mm vertically for a frequency of 0.1 Hz to 100 Hz.
Several hundred equipment for the future reactor will have to be tested. Emitech supports testing campaigns throughout France and provides diagnostics, solutions and recommendations on equipment submitted to the specific specifications of the Iter project.
