Specialists from NRNU MEPhI, together with colleagues from China, have proposed a new alloy that is suitable for the inner walls of the ITER (International Thermonuclear Experimental Reactor, the experimental reactor is located in the south of France) thermonuclear reactor under construction, the university's press service reported.
The press service explained that the experimental alloy was created on the basis of tungsten with the addition of yttrium and chromium. After processing with high-vacuum annealing, the alloy showed high resistance to deuterium exposure (heavy hydrogen, used in nuclear energy).
Currently, refractory tungsten is used as the material for the reactor walls. It is used in research reactors in Britain, Germany and France.
However, physicists believe that the flows of heat and particles will be higher in future thermonuclear reactors. In this regard, tungsten may degrade and become unsuitable for use.
