The ITER port limiter design

摘要

The limiters in the International Thermonuclear Experimental Reactor (ITER) have been relocated to equatorial ports in order to improve their operability and maintenance. This position reduces to a minimum the total first wall (FW) area subjected to high heat fluxes with resulting savings in component costs along with those in the associated cooling water system. Installation in the ports allows the limiter position to be adjusted from outside the cryostat and greatly simplifies the remote handling tasks required for their replacement.
