AbstractAn important aspect of the development of potential structural materials for fusion power plants is their activation by 14-MeV neutrons. At present vanadium alloys of type V–Ti–Cr are considered as promising for this application. Among them the alloys with additions of up to 10% of Ti and of 4–6% of Cr are the most widespread. An activation study of some Russian candidate vanadium alloys was carried out at the SNEG-13 facility. Various samples were studied: three types of vanadium alloy with different additions of Ti and Cr, and the samples of their main components-pure V, Cr, Ti produced by various technologies. All the samples were irradiated in identical conditions in a neutron field with a well certified neutron spectrum. The experimental data are compared to calculations with FISPACT code using the activation data from EASY-99 System.

核融合発電プラント用の潜在的な構造材料の開発における重要な側面は、14-MeV中性子によるそれらの放射化である。現在、この用途にはV–Ti–Cr型のバナジウム合金が有望視されている。それらの中でも、Tiを最大10%、Crを4–6%添加した合金が最も広く使用されている。SNEG-13施設において、ロシアのいくつかの候補バナジウム合金の放射化研究が実施された。様々な試料が研究された:TiおよびCrの添加量が異なる3種類のバナジウム合金と、様々な技術で製造された純成分であるV、Crの試料である。全ての試料は、十分に認定された中性子スペクトルを有する中性子場において同一条件下で照射された。実験データは、EASY-99システムの放射化データを用いたFISPACTコードによる計算結果と比較された。
