    Notes: Abstract Main directions of work on experimental fusion reactors safety assurance in Russia are given. Work on safety includes: the elaboration of the main criteria and principles of safety assurance, the development of the first priority standards in safety on the basis of the fission experience and international safety documents requirements, fusion reactor safety analysis, and work to provide a base for the standards development and for the safety analysis activity. The results of some work on fusion safety are presented. They include: assessments of safety and reliability of Liquid Metal Cooling System draft design, evaluations of the buildings and equipment response on external dynamic influences, and analysis of radiological situation in th environment as a result of tritium-containing dust release.

    Notes: Abstract ITER will be the first large-scale tokamak to be designed as a nuclear facility to provide public protection from external hazards such as earthquakes. The design approach for such events has been developed consistent with ITER's moderate hazards and overall safety approach on a basis of the ITER site assumptions. Seismic design is described including selection of ground motions for design purposes, seismic safety requirements, and the seismic classification scheme. The results of preliminary seismic assessments are summarized including the potential for seismically induced plasma vertical displacement events (VDE). Finally, potential facility modifications available to deal with site-specific external hazards are suggested. At the Detailed Design Report stage of the Engineering Design Activity (EDA), it is concluded that ITER has been designed to deal with the site design assumptions for earthquakes and can be designed to safety cope with a range of site-specific external hazards with modest changes to the facility.

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