Nuclear heating experiments for the validation of fusion reactor shielding performance

P. Batistoni, M. Angelone, M. Pillon, V. Rado1997年Fusion Engineering and DesignIF 1.7出版社

AbstractNuclear heating experiments were performed at the 14 MeV Frascati neutron generator, with the purpose of validating the shielding performance of the International Thermonuclear Experiment Reactor (ITER) shielding system (first wall, shielding blanket and vacuum vessel). The experiments consisted of the irradiation, with 14 MeV neutrons, of large assemblies that simulated, for size and material composition, the shielding system and the toroidal field magnet. The nuclear heating was measured with different thermo-luminescent detectors, as a function of the penetration depth inside the assemblies. The experimental results obtained were compared with the same quantities calculated with the same nuclear database and code used for nuclear heating calculations in the ITER design.

核加熱実験は、国際熱核融合実験炉(ITER)の遮蔽体系(第一壁、遮蔽ブランケット、真空容器)の遮蔽性能を検証する目的で、14 MeVフラスコ中性子発生装置において実施された。実験は、遮蔽体系とトロイダル磁場コイルを、寸法および材料組成の観点から模擬した大型アセンブリを、14 MeV中性子で照射することから構成された。核加熱は、アセンブリ内部への侵入深さの関数として、異なる熱蛍光線量計を用いて測定された。得られた実験結果は、ITER設計における核加熱計算に使用されたものと同じ核データベースおよびコードを用いて計算された同一の量と比較された。
