2005年12月にITER機器の調達分担がまとめられ、第一壁では性能評価試験の必要性が、規定された。これに基づいて、主要な内容とマイルストンを定めた「調達計画」が策定されている。中国,EU,日本,韓国,ロシア,USの6極による、1700枚の第一壁パネルの製作を考えると性能評価のための試験は不可欠である。性能評価のためのモックアップは80$$times$$240$$times$$81mm(3枚のBeタイル)の大きさで、EUとUSの試験設備を用いて熱負荷試験を行う。ITER第一壁の熱負荷条件は最大0.5MW/m$$^{2}$$(定常)$$times$$30,000回である。標準化された方法により機械強度試験も行う。試験結果が所定の条件を満足した極のみが、ITER第一壁の調達を行うこととなる。セミ・プロトタイプの製作もITER実機の製造前に行う予定である。

In December 2005, the new procurement allocation plan of the ITER components among the seven Parties was prepared. The need to qualify for procurement of the specific components was especially introduced in the document. The main features and milestones of the qualification program are described in "Procurement Plan" for each specific component. Due to the complicated features of FW procurement, the procurement document has to be developed precisely. To guarantee high quality of 1700 FW panels produced by 6 different Parties, a qualification program is essential. The qualification mock-up is 80 mm wide, 240 mm long and 81 mm thick with 3 beryllium tiles 10 mm thick. Heat load tests will be performed on the qualification mock-ups in 2007 in EU and USA facilities. The maximum design heat load on the ITER FW is 0.5 MW/m $$^{2}$$ (steady state) $$times$$ 30,000 shots. Mechanical tests of joints are also required using standardized methods. Only Parties which have satisfied the acceptance criteria of the qualification tests can proceed to the procurement stage of the ITER FW. Semi-prototypes (roughly 1000 mm $$times$$ 200 mm) are also requested before the ITER FW manufacturing.
