ITER limiter first wall 3-D thermo-mechanical analysis

The International Thermonuclear Experimental Reactor (ITER) is a tokamak reactor being built not only to demonstrate the controlled ignition and extended burn of DT plasmas but also to prove the reliability and maintainability of different reactor systems. The limiter is needed to protect the reactor first wall (FW) during plasma startup and shutdown. The work reported here describes in part the design activity related to the FW for the ITER limiter. The main objective of this analysis is to determine the effect of the groove depth in the Cu on the limiter first-wall stress field. 2 refs., 4 figs., 1 tab
