预算限制迫使 ITER 组织重新考虑基准偏滤器策略，其中操作将从高热通量区域的碳 (C) 开始，在第一次核活动之前改为全钨 (W) 变体。如果取消这两个偏滤器之一，就可以大幅降低成本。新战略不仅意味着 ITER 将在全 W 偏滤器上启动，而且该组件应该一直存活到进入核阶段。本文考虑了这种方法在已知的钨等离子体-材料相互作用问题方面产生的风险，并简要介绍了可能的全钨偏滤器设计的现状。 (C) 2013 ITER 组织。由 Elsevier B.V. 出版。保留所有权利。
Budget restrictions have forced the ITER Organization to reconsider the baseline divertor strategy, in which operations would begin with carbon (C) in the high heat flux regions, changing out to a full-tungsten (W) variant before the first nuclear campaigns. Substantial cost reductions can be achieved if one of these two divertors is eliminated. The new strategy implies not only that ITER would start-up on a full-W divertor, but that this component should survive until well into the nuclear phase. This paper considers the risks engendered by such an approach with regard to known W plasma-material interaction issues and briefly presents the current status of a possible full-W divertor design.
