Abstract A radioactive corrosion product, Chalk River unidentified deposit (crud) was sampled and analyzed using an electron probe micro-analyzer with zinc-injected spent nuclear fuel rods (HU Unit 1, actual burnup 49 655 MWd/tonne U). Hot-cell facilities, a space for handling highly radioactive materials, were used as a way to collect crud deposited in the fuel rod cladding tube at a specific location of the spent fuel rod. A soft collection method for collecting crud using rubbings or adhesive tape was used to collect a sample, and a sample was collected with hard collection using a steel knife from the cladding tube of the fuel rod. The spent fuel rods were used for two cycles burned after zinc was injected into the primary coolant, which is known to inhibit the generation of crud. To compare the analysis results of the soft and hard collection methods for sampling crud, the results of the crud collected using an ultrasonic wave system were analyzed. The crud used in this study used burned fuel rods for two cycles after zinc ions were injected into the primary coolant. Based on the results, the Ni/Fe ratio can be estimated to be about 1.18. The Ni/Fe ratio value of 1.18 derived from this study is not much different from the Ni/Fe ratio values derived from nuclear power plants operating around the world.

三种取样方法的分析结果比较，原油是一种具有注入锌的乏压水堆核燃料棒的放射性腐蚀产物

摘要 使用带有注锌乏核燃料棒的电子探针显微分析仪（HU Unit 1，实际燃耗 49 655 MWd/tonne U）对一种放射性腐蚀产物 Chalk River 不明沉积物（crud）进行采样和分析。热室设施是处理高放射性材料的空间，被用作收集沉积在乏燃料棒特定位置的燃料棒包壳管中的渣滓的方法。使用摩擦或胶带收集碎屑的软收集方法收集样品，使用钢刀从燃料棒的包壳管收集样品，硬收集。在将锌注入主冷却剂后，废燃料棒被用于燃烧两个循环，众所周知，主冷却剂可以抑制结渣的产生。为了比较软硬收集方法对采样粗渣的分析结果，分析了使用超声波系统采集粗渣的结果。在将锌离子注入主冷却剂后，本研究中使用的 crud 使用燃烧过的燃料棒进行两个循环。根据这些结果，Ni/Fe 比率可以估计为大约 1.18。本研究得出的 Ni/Fe 比值为 1.18，与世界各地运行的核电站得出的 Ni/Fe 比值差别不大。
