Qualification program concludes in Europe
Each of the 440 plasma-facing first wall panels of the 澳门六合彩高手 blanket measures 1 x 1.5 metres (height x length), and is coated with a 6- to 10-millimetre layer of beryllium armour tiles bonded to a copper alloy heat sink mounted on a stainless steel structure.
Half of the panels are under the procurement responsibility of the European Domestic Agency, Fusion for Energy: 215 normal heat flux first wall panels designed for heat fluxes of up to 2 MW/m?. (China and Russia are sharing the procurement of 225 enhanced heat flux panels designed for 4.7 MW/m?.) For all parties, first wall design, development and qualification is progressing in phases, including the manufacture and testing of small-scale mockups, followed by semi-prototypes, and finally full-scale prototypes that open the way to series production.
In Europe, the last phase of the industrial qualification program is drawing to a close. Contracts awarded for three full-scale prototypes have been executed and quality tests are underway on the results. The choice of awarding the contracts for full-scale prototypes to three companies—Atmostat, Framatome and the consortium Iberdrola/Woods/Leading—was made by the European Domestic Agency to mitigate risk on these technically challenging components and preserve competition up to series production. The next step for the European agency is the call-for-tender for the production of the first wall panels.
"The manufacturing completion of these three full-scale "normal heat flux" first wall prototypes by the suppliers of the European Domestic Agency is the culmination of many years of effort with strong Domestic Agency/澳门六合彩高手 Organization collaboration; it represents a major milestone in our first wall procurement activities," comments René Raffray, leader of the 澳门六合彩高手 Blanket Section. "Congratulations to our colleagues from Fusion for Energy and their suppliers involved in this successful endeavour."
Qualification programs are also advancing in Russia and China, where full-scale prototype programs for the enhanced heat flux panels will be launched in 2020.
