The hottest stuff in 澳门六合彩高手
During a in Europe for the inner vertical target, multiple suppliers had fabricated and tested small-scale (~1/20th) mockups of the tungsten monoblocks mounted around cooling channels. As a follow-up step, pre-qualified manufacturers were invited to produce full-scale prototypes—half-tonne, 1.5-metre-long components that are made of a massive curved steel support structure armoured with 1,104 tungsten monoblocks actively cooled by pressurized water.
"This scale-one prototype demonstrates industry's ability to manufacture such a demanding piece—fulfilling the 澳门六合彩高手 requirements on line with nuclear standards, in particular in terms of welding techniques," says Frédéric Escourbiac, leader of the Divertor Section. "On top of this, the prototype respects the stringent tolerances imposed by the need to align the components in the machine perfectly. It's a great first step; we need now together with our Domestic Agency partners to deploy the effort to ensure a similar level of performance during series production.
Ansaldo Nucleare (Italy) is the first supplier to complete its prototype, in collaboration with its main subcontractors Ansaldo Energia, ENEA and Walter Tosto. The prototype will now be shipped to the Efremov Institute in Saint Petersburg for a series of thermal tests.
