| 摘 要： | 概述了法国法马通公司开发的新型燃料包壳材料 M5合金在堆内外的腐蚀、吸氢、显微组织、蠕变、辐照生长等性能。从已获得的堆内数据证明， M5合金包壳在抗腐蚀、吸氢、蠕变、辐照生长方面大大优于最佳化的 Zr- 4合金包壳。可以预计， M5新合金包壳能满足燃耗达 65GW· d· t－ 1的设计要求。在法马通推出的 PWR燃料组件 AFA- 3G已采用了 M5合金包壳。

| Abstract: | The out-of-pile and in-pile corrosion,mechanical properties,microstructure,hydrogen absorption,creep and growth resistances of M5 alloy using as PWR fuel rod cladding materials developed by FRAMATOME in France has been summarized with reference to the literatures.The results obtained from in-pile irradiation tests show that the corrosion and hydrogen absorption resistances,creep and irradiation growth resistances of M5 alloy cladding are superior to that of the optimized Zircaloy-4.It could be estimated that the M5 alloy enables rod burnups close to 65GWd/tU to be reached. |
