Experimental investigation of radioactivities induced in fusion reactor materials by 14-MeV neutrons

AbstractSamples of MANET steel, a potential structural material for first wall and blanket of fusion devices, and of Stainless Steel 316, the structural material of the ITER shield blanket, were irradiated with 14-MeV neutrons at the facility SNEG-13. Gamma spectra were taken with Ge(Li)-spectrometers several times during 1 year of cooling. Twelve different gamma activities induced were determined. The inventory code FISPACT and the European Activation File EAF-4 were used for calculating the activities. Ratios of calculated-to-experimental values are presented for the gamma emitters dominating during this period. The time dependences of the total activity of gamma emitters in both materials are directly compared and discussed in conjunction with the calculated results.

MANET鋼(核融合装置の第一壁およびブランケットの候補構造材料)およびステンレス鋼316(ITER遮蔽ブランケットの構造材料)の試料を、SNEG-13施設において14-MeV中性子で照射した。ガンマ線スペクトルは、Ge(Li)検出器を用いて1年間の冷却期間中に数回測定した。12種類の異なる誘導ガンマ線放出核種の放射能を決定した。放射能の計算には、インベントリコードFISPACTおよび欧州活性化ファイルEAF-4を使用した。計算値と実験値の比を、この期間中に支配的なガンマ線放出核種について示した。両材料におけるガンマ線放出核種の総放射能の時間依存性を直接比較し、計算結果と併せて考察した。
