Steam is a sign of cooling system function . . . at ITER
Steam from one of ITER’s ten induced-draft cooling cells offers visual confirmation of a successful cooling system test, the ITER organization announced April 30. ITER’s cooling system features 60 kilometers of piping with pumps, filters, and heat exchangers that can pull water through at up to 14 cubic meters per second. Once fully operational, two cooling loops—one to remove the heat generated by the plasma in the ITER tokamak and one for its supporting infrastructure—will be capable of extracting up to 1,200 MW of heat.

As part of the International Thermonuclear Experimental Reactor (ITER) plasma fueling development program, Oak Ridge National Laboratory has fabricated a pellet injection system to test the mechanical and thermal properties of extruded tritium. This repeating single-stage, pneumatic, Tritium-Proof-of-Principle Phase II (TPOP-II) Pellet Injector has a piston-driven mechanical extruder and is designed to extrude and accelerate hydrogenic pellets sized for the ITER device. Tritium and deuterium-tritium (D-T) pellets have been produced in experiments at the Los Alamos National Laboratory Tritium Systems Test Assembly. About 38 g of tritium was used in the experiment. This paper presents results of the TPOP-II extrusion experiments. These extrusion experiments indicate that both T2 and D-T will require higher extrusion forces than D2 by about a factor of 2 and that the flow of the material may be characterized by static and dynamic shear strengths.
