Performances of inert gas glow discharges for reductions of fuel hydrogen retention and helium retention [PDF]

Fusion Engineering and Design, 2010
Abstract In order to clarify the effects of inert gas discharges on the reduction of fuel hydrogen retention, the inert gas discharge has to be similarly conducted in the same apparatus with the same conditions. In the present experiment, first, the hydrogen glow discharge was conducted to measure the fuel hydrogen retention.

Fuel retention studies with the ITER-Like Wall in JET [PDF]

Nuclear Fusion, 2013
JET underwent a transformation from a full carbon-dominated tokamak to a fully metallic device with beryllium in the main chamber and a tungsten divertor. This material combination is foreseen for the activated phase of ITER. The ITER-Like Wall (ILW) experiment at JET shall demonstrate the plasma compatibility with metallic walls and the reduction in ...

Gas balance and fuel retention in fusion devices [PDF]

Nuclear Fusion, 2007
The evaluation of hydrogenic retention in present tokamaks is of crucial importance to estimate the expected tritium (T) vessel inventory in ITER, limited from safety considerations to 350 g. In the framework of the European Task Force on Plasma Wall Interaction (EU TF on PWI) efforts are underway to investigate gas balance and fuel retention during ...
