The reduction of long-term radioactivity is analysed here in V–Cr–Ti alloys, one of the proposed structural materials for fusion power plants. In particular is explored the possibility of recycling within the nuclear industry and of clearance, that is declassification to non-active material. Vanadium alloys have the potential to reach the dose rate hands-on recycling limit when used in a blanket, if noxious radioactive products coming from impurities activation are eliminated. Clearance is also possible in principle, but only if further separation of activation products of titanium is carried out after service.

V-Cr-Ti合金における長期放射能の低減について、核融合発電所の構造材料の候補として分析する。特に、核産業内でのリサイクル可能性と、非放射性物質への分類(クリアランス)の可能性を探る。バナジウム合金は、ブランケット内で使用される場合、不純物の活性化によって生じる有害な放射性生成物を除去すれば、直接取り扱い可能なリサイクルレベルに達する可能性がある。また、使用後にチタンの活性化生成物をさらに分離すれば、クリアランスも原理的には可能である。
