Zusammenfassung: | PROBLEM TO BE SOLVED: To provide irradiation target holders for generating radioisotopes, allowing safer and easier handling and harvesting; and to provide methods for generating the same.SOLUTION: Irradiation target holders 100 are configured to fit in open locations inside of an operating commercial nuclear core 35. The holders can be placed with ends at vertical bottom and top of the core 35 or any position therebetween to directly expose the holders to nuclear fuel reactions. The holders have ends and overall shape that can join with existing reactor structures, while fitting closely with fuel 45 and moderator and being easily removable from the same. The holders are fabricated of any reactor-compatible material that will retain irradiation targets 151 and daughter products. The holders can be installed during reactor outages and irradiated during operation without risk of movement or interference with operation. The holders can be harvested from the core 35 independent of other core structures and fuel.SELECTED DRAWING: Figure 3
【課題】安全でより簡単な取扱い及び回収を可能とする放射性同位元素生成用の照射ターゲットホルダとその生成方法を提供する。【解決手段】照射ターゲットホルダ100は、動作中の商用核炉心35の内側の開放位置に設けられ、前記炉心35の垂直な底部・上部におけるまたはホルダを核燃料反応に直接曝すそれらの間の任意の位置における端部に配置され、既存の炉構造と連結できる端部・全体形状を有する一方、燃料45および減速材と密接にフィットしつつかつそこから容易に除去でき、また、照射ターゲット151・娘生成物を保持する任意の炉適合材料で製造される。さらに、炉停止中に設置することができるとともに、移動のリスク/動作との干渉なしで動作中に照射することもでき、他の炉心構造・燃料から独立して前記炉心35から回収できる。【選択図】図3 |
