U.S. ITER Limiter Module Design

The recent U.S. effort on the ITER (International Thermonuclear Experimental Reactor) shield has been focussed on the limiter module design. This is a multi-disciplinary effort that covers design layout, fabrication, thermal hydraulics, materials evaluation, thermo-mechanical response, and predicted response during off-normal events. The results of design analyses are presented. Conclusions and recommendations are also presented concerning the capability of the limiter modules to meet performance goals and to be fabricated within design specifications using existing technology.
