ITER safety: Lessons learned for the future

The International Thermonuclear Experimental Reactor (ITER) Project include s a vigorous safety design and assessment activity to demonstrate the safet y potential of ITER and to demonstrate that it can be sited in any of the s ponsoring Parties with a minimum of site-specific redesign. The scope and d epth of the ITER Engineering Design Activities (EDA) safety effort was unpr ecedented for fusion. In this paper, we discuss a number of lessons that ha ve been learned during the safety effort of the ITER EDA and their implicat ions for fusion in the longer term.
