The release of fission products to the environment is one of the concerns with nuclear power. During an accident, the most likely released are the volatile fission products i.e., tellurium. To evaluate the behavior of tellurium in the event of an accident, it was heated under different conditions (oxidizing, inert, reducing; both dry and humidified). The formed vapor was transported to surfaces (aluminum, copper, zinc) at room temperature that can be found in the BWR-containment. All formed deposits were examined for morphology and species. Moreover, the content of sodium hydroxide liquid traps following the metal surfaces and filter was also investigated. In these traps, the highest amount of tellurium was found under humid-reducing followed by humid-oxidizing conditions. In the deposit removed from the zinc surface acquired under the latter conditions, elemental analysis observed zinc, indicating a possible reaction between tellurium and zinc. The corresponding trap showed significant amounts of zinc. (C) 2020 The Author(s). Published by Elsevier Ltd.

严重核事故期间 BWR 安全壳中潜在的碲沉积物

裂变产物释放到环境中是核电关注的问题之一。在事故期间，最有可能释放的是挥发性裂变产物，即碲。为了评估发生事故时碲的行为，将碲在不同条件下加热（氧化、惰性、还原；干燥和加湿）。形成的蒸汽在室温下传输到表面（铝、铜、锌），可以在 BWR 安全壳中找到。检查所有形成的沉积物的形态和种类。此外，还研究了金属表面和过滤器后氢氧化钠液体捕集器的含量。在这些陷阱中，在减湿条件下发现的碲含量最高，然后是湿氧化条件。在后一种条件下从锌表面去除的沉积物中，元素分析观察到锌，表明碲和锌之间可能发生反应。相应的陷阱显示出大量的锌。(C) 2020 作者。由爱思唯尔有限公司出版。
