ITER project phase 2 started: working on a future nuclear fusion reactor

Cocoon has started the second phase of the ITER Project in the South of France. A project that is working on a trial version of a future nuclear fusion reactor. Last year the first phase of our assignment for ITER was completed.

A look back at the 1st phase of the ITER Project

In 2018, Cocoon was engaged for a very special project, namely the ITER project.

ITER is working on a tokamak, an immense installation that should teach us how to generate energy in an environmentally friendly and cost-effective way.

The ultimate goal of this project is to build an even larger tokamak that is commercially viable and can realize a very large fusion.

No fewer than 36 countries are participating in this project. The expectation is that around the year 2050 we will have more information about whether this device is suitable for solving the world’s energy problem.

Preservation of the cryostats on the lower cylinder by Cocoon

During the first phase of the ITER project, Cocoon preserved the Lower Cryostat Cylinder of the tokamak by using mothballing.

The components are largely ready, but can only be installed after 5 years. To prevent rust and mold, the cylinders are covered by Cocoon with 2200 m2 of special airtight Cocoon foil.

After this, the parts with a diameter of 30 meters and a height of 12 meters are sprayed with the Cocoon skin. This makes them resistant to all weather conditions, moisture and dust.

A huge job that required a lot of calculation, planning, insight and collaboration.


What does phase 2 of the ITER project look like?

Cocoon has now started the second phase of the ITER project. In this phase we are going to wrap the Upper Cryostat Cylinder of the tokamak.

How do we proceed when wrapping the cryostats?

First of all, foil must be produced. The cryostats, which ensure that the temperature remains at the same level, are so large that a lot of foil has to be made to measure. The foil is then transported to France, where the nuclear fusion reactor is built.

On location the cylinders are wrapped with Cocoon foil and sprayed with the Cocoon skin. With our special mothballing system we can preserve the parts for years, after which they are still as new.

The expectation is that the ITER project can be completed after a few weeks. 

Who is involved from Cocoon?

Everyone from Cocoon participates in this project. The Cocoon engineers carry out the technical work on location. The Cocoon director keeps the overview on location. And from the office, people contribute to the necessary documentation, planning and logistics.

We will keep you informed about the progress of this special project.


Want to know more about Cocoon’s work?

In addition to the ITER project, there are other great jobs that Cocoon carries out. We specialize in preserving materials, so that corrosion and mold do not stand a chance.

We perform this for large and smaller projects. Would you like more information about Cocoon? Then contact us.
