ITER's vacuum vessel port plugs are critical components that seal the plasma chamber and allow experiments to take place in a high vacuum environment.

The Russian Domestic Agency—responsible for supplying four test stands for the vacuum, heat and functional testing of the port plugs before their installation on the machine—has contracted with the Russian firm Cryogenmash for the development of the technology.

The team at Cryogenmash is currently testing the sealing flanges that will secure the port plugs on the test stand and running tests on the gaskets to arrive at a final choice of technology and material. Vacuum and leak tests were run recently with results that surpassed expectations.
