It is now the end of April 2018 and that means that we have completed the preparation phase of project Iter. Cocoon will conserve the cryostats of the largest nuclear fusion reactor on earth. Meanwhile all the paperwork has been arranged and we can start with the implementation. 

The preparation, what did that look like?

How are we going to pack the cryostat cylinder? Where are we going to connect? How are we going to embed the transport frame? How is the installation plan, and how are we going to apply it? What is the inspection procedure?

These were just a few of the questions that we had to answer during the preparation phase. The goal is to define our mothballing system as clear as possible for Iter. After we made all the preparations, we were able to get started with the execution.

Let’s start: packing the cryostats.

The first thing to do is to produce the foil. The cryostats of the reactor are immense, which means that we have to make 2200 m2 of custom-made foil. We do this by hand, for the highest possible quality. After six weeks we will complete this phase.

This will then be put on transport to France, where the nuclear fusion reactor is being built. There we can start at the end of July with encapsulating the cryostat cylinder. The cylinder will not be used until 2029, but with our mothballing system we can perfectly preserve the cylinders.
