Cryo test facility for the ITER solenoid module successfully accepted

October 14, 2016

Bilfinger subsidiary Babcock Noell recently delivered the cryostatic system for the final test of the ITER Central Solenoid (CS). It was successfully accepted by the customer, General Atomics (GA) in the presence of the end customer ITER.

The cryo test facility is used in connection with other partial systems to conduct tests on magnet modules at extremely low temperatures. The final testing includes vacuum leak tests, high tension tests for electrical insulation, cryogenic tests and full-flow tests at a temperature of -269 °C. Here, extremely high magnetic fields are generated from the spools.

In the next step, specialists from Babcock Noell will train the GA staff at the site so that they can conduct the comprehensive tests of the ITER spools with the test chamber.

ITER, which has been under construction since 2007, is a nuclear fusion reactor and an important international research project with the objective of demonstrating the scientific and technological feasibility of fusion energy. The CS magnet system is one of the supra-conducting magnet groups that reduce contact of hot plasma with the walls inside the reactor chamber to a minimum. It is thus one of the key components of the ITER machine. The CS magnet system consists of 6 individual modules. These will be assembled at a later point in time at the ITER location in Southern France and will form a 12.8 meter high supra-conducting magnet system.
