| 摘 要： | 核材料中子辐照损伤是影响核能装置安全性和稳定性的关键问题之一。由于难以开展大量的中子辐照实验来评估核材料的损伤机理，因此相关理论模拟至关重要。介观尺度团簇动力学（CD）模型由于不受时间和空间尺度的限制，是一种研究材料中子辐照损伤长时间演化的有效方法。本文综述了CD的模型、数值算法和最新进展，重点介绍了CD在典型核材料的中子辐照问题中的系列应用，并对CD的未来发展进行了展望。

| Abstract: | Neutron radiation damage in nuclear materials is one of key issues affecting the safety and stability of nuclear energy devices. Due to difficulties in conducting numerous neutron irradiation experiments of nuclear materials to evaluate their damage mechanisms, relevant theoretical simulations are crucial. With no restriction in space and time scales, meso-scale cluster dynamics (CD) is an effective approach to study the long-term dynamic evolution of radiation damage in materials. In this review, an overview of the model, numerical algorithms and latest progress of CD was given, a series of applications of CD were highlighted for typical issues in nuclear materials under neutron irradiation and future development of CD was also prospected. |
