Pellet Selector/Injector for ITER Project


ADC provided the design, engineering, and procurement of material, manufacture, assembly, inspection, test, and installation of a pre-prototype pellet Injector as a part of the International Thermonuclear Experimental Reactor for Oakridge National Lab. Fusion is the process of having the nuclei of two light atoms forming into one heavier nucleus. The result is a release of more energy than put into the action. This is the same process generated by the sun and most other stars.


The pellets are directed into three possible plasma locations by the flight tube selector. The pellets exit the selector and travel through flight tubes that penetrate the cryostat and vacuum vessel before entering the plasma on either the outer diameter (low field side) or inner diameter (high field side). The geometries of the flight tubes have been optimized to maximize bend radii over 800 mm to ensure intact pellets traveling at >200 m/s.
