Understanding irradiation damage and effects in α-uranium (α-U) is critical to modeling the behavior of U-based metallic fuels. The aim of this review is to address the renewed interest in U-based metallic fuels by examining the state-of-the-art knowledge associated with the effect of irradiation on the microstructure, dimensional changes, and properties of α-U. We critically review the research progress on irradiation-induced growth and swelling, the enhancement of plastic flow and superplasticity by irradiation, and the effect of irradiation on thermal and electrical properties of α-U. Finally, we outline the research directions that require advancements, specifically the need to carry out fundamental research on several of the less understood mechanisms of irradiation damage and effects in α-U.
了解α-铀（α-U）中的辐照损伤和效应对于模拟铀基金属燃料的行为至关重要。本综述的目的是通过研究与辐照对α-U的微观结构、尺寸变化和性能的影响相关的最新知识，来回应人们对铀基金属燃料重新燃起的兴趣。我们批判性地回顾了辐照诱导生长和肿胀、辐照增强塑性流动和超塑性以及辐照对α-U热性能和电性能影响方面的研究进展。最后，我们概述了需要取得进展的研究方向，特别是需要对α-U中一些尚不太了解的辐照损伤和效应机制开展基础研究。
