Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

In a Deuterium-Tritium fusion reactor, nearly 20% of the thermal power has to be transferred from the hot plasma through the wall components of the burn chamber. Design requirements of commercial fusion power plant in-vessel components are potentially even more stringent than those of experimental devices. Fusion nuclear reactor studies are currently devoted mostly to the Deuterium-Tritium (DT) fuel cycle, since it is the easiest way to reach ignition or a high energy gain. However, reducing the activation of materials is one of the biggest concerns for fusion power: the study of advanced fuel fusion devices, such as the CANDOR Deuterium-Helium-3 (DHe3) tokamak, is proposed for this purpose. The plasma confinement requirements for a DHe3 reactor are much more challenging than those for a DT reactor. Thus, the demands on the divertor and the first wall are more severe, particularly during a disruption. Safety analyses, starting from heat load determinations, have been performed for CANDOR, a proposed DHe3 experiment, starting from similar evaluations carried out for the ARIES III DHe3 reactor.
