摘要

在核电站，用于电绝缘的聚合物会受到放射性射线的照射，这取决于它们安装的地方。如果发生事故，这种聚合物也可能遭受高温蒸汽暴露。我们进行了几项实验，旨在阐明热应力、伽马射线辐照和蒸汽暴露对各种绝缘聚合物的影响，并发现伽马射线辐照可以减轻蒸汽暴露引起的几种聚合物的降解。

Mitigation of Degradation in Polymers by Gamma Rays

In nuclear power plants, polymers used for electrical insulation are irradiated by radioactive rays, depending on the places where they are installed. If an accident occurs, such polymers may also suffer high-temperature steam exposure. We have conducted several experiments that aim at clarifying the effects of thermal stresses, gamma-ray irradiation, and steam exposure on various insulating polymers and have found that gamma-ray irradiation can mitigate the degradation induced by the steam exposure in several polymers.
