摘　　要：本文介绍了辐照引起Ｕ３Ｓｉ破裂性肿胀和Ｕ３Ｓｉ２稳定性肿胀的规律及其与显微结构变化的关系。实验证实了Ｕ３Ｓｉ２－Ａｌ板型燃料在超高通量堆中使用的可行性与制造当量铀密度７ｇ·ｃｍ－３燃料板的可能性。Breakaway swelling of U3Si2 and stable swelling of U3Si2 caused by irradiation, as well asthe correlation between swelling and microstructure changes, are described. The experimentsconfirm that it is feasible to using U3Si2-Al as very high flux research reactor fuel and it is possible to fabricating fuel plate with equivalent uranium density 7g. cm-3.
