摘要
石墨因其具有优异的高温性能和良好的核能技术而用于反应堆中。但石墨受到辐照的影响 ,使其物理性能发生改变 ,从而影响它的使用寿命。对我国部分国产细颗粒石墨 ,即等静压石墨和三高石墨 ,进行辐照行为研究 ,得到了石墨尺寸变化和热膨胀系数变化数据 ,分析辐照对石墨寿命的影响 ,并评价我国石墨辐照性能指标。
Graphite is widely used because of excellent high temperature performance. The graphite is influenced by irradiation, so its using life is changed. Irradiation of graphite made in China, including SIFC and TSXC 2 650 graphite, is reviewed in the paper. Data about isze and CTE changes of SIFC and TSXC 2 650 graphite were obtained. Using data about is performance of irradiatin of graphite made in China, how irradiation is evaluated influences the using life is analyzed and the performance of irradiation of graphite made in China is evaluated.
