SAFETY AND ENVIRONMENTAL ACTIVITIES FOR ITER

This paper will summarize highlights of the safety approach and discus s the ITER EDA safety activities. The ITER safety approach is driven b y three major objectives: (1) Enhancement or improvement of fusion's i ntrinsic safety characteristics to the maximum extent feasible, which includes a minimization of the dependence on dedicated ''safety system s''; (2) Selection of conservative design parameters and development o f a robust design to accommodate uncertainties in plasma physics as we ll as the lack of operational experience and data; and (3) Integration of engineered mitigation systems to enhance the safety assurance agai nst potentially hazardous inventories in the device by deploying well- established ''nuclear safety'' approaches and methodologies tailored a s appropriate for ITER.
