On the pharaonic construction site of the prototype of the ITER nuclear fusion reactor at the Cadarache site (Bouches-du-Rhône), it is not just the workers who are busy. The engineers had to change their priorities to respond quickly to the long list of requests from the Nuclear Safety Authority (ASN), so that the assembly of this unique machine in the world continues on schedule.
ASN's requests, in the form of a letter addressed by its chairman to the director general of the international organization ITER, were revealed on 21 February by the news site New Energy Times, which is highly critical of the energy of merger. The missive is not good news. It indicates that, as it stands, the assembly of the reactor cannot begin, in particular the key and irreversible stage of welding the first two elements together, out of nine, constituting the vacuum chamber 19.4 meters in diameter and 11.4 meters high, in which the fusion reactions must take place.
