实习题目：

对铬涂层锆包壳材料共晶反应机理的研究

The eutectic reaction in Chrome-coated Zircon alloy cladding

实习内容：

铬涂层锆合金包壳中铬-锆共晶反应对包壳的高温氧化及其韧脆特性影响显著，因此本实验旨在研究反应堆中燃料棒的锆包壳材料与含铬涂层间的共晶反应机理，利用高温反应炉探究反应温度，接触面压强、反应物组分等不同因素对于铬锆共晶反应速率的影响。在得出实验数据后，利用移动粒子半隐式方法（MPS）对不同实验参数下的铬锆共晶反应过程进行数值模拟，验证MPS方法对于铬锆共晶反应模拟的适用性并尝试建立铬锆共晶反应模型。

The eutectic reaction in Cr-coated Zr alloy cladding have significant effects on the high-temperature oxidation and mechanical properties of the cladding. Therefore, this experiment aims to investigate the eutectic reaction mechanism between the Zr cladding material and the Cr-containing coating. The high-temperature reaction furnace is used to explore the influence of different factors such as reaction temperature, contact surface pressure, and reactant composition on the eutectic reaction rate between Cr and Zr. After obtaining the experimental data, the moving particle semi-implicit method (MPS) is used to numerically simulate the eutectic reaction process between Cr and Zr under different experimental parameters to verify the applicability of the MPS method for simulating the eutectic reaction, and attempt to establish a eutectic reaction model for Cr-coated Zr alloy cladding.

实习题目：

铅冷快堆严重事故下FCI特性研究

Characterization of FCI under severe accidents in lead-cooled fast reactors

实习内容：

本实验研究的对象为第四代反应堆中的铅冷快堆在发生严重堆芯解体事故(CDA)之后，熔融燃料和其他堆芯熔融物注入冷却剂后发生的碎裂行为。

本实验着重关注冷却剂物性参数对熔融物碎化行为的研究。使用高温加热设备等实验仪器以调整实验参数，随后对碎化物进行球形度、尺寸、碎片床孔隙率的测量。在得出实验数据后，使用Rayleigh-Taylor不稳定性、Weber数理论、Kelvin-Helmholtz不稳定性、Froude数理论等方法，探究与验证冷却剂物性对碎化行为的影响。

This experiment investigates the fragmentation behavior of molten fuel and other core melt injected into the coolant after a severe core disintegration accident (CDA) in a lead-cooled fast reactor of Generation IV reactor.

This experiment focuses on the study of the melt fragmentation behavior by coolant physical parameters. Experimental apparatus such as high-temperature heating equipment were used to adjust experimental parameters, followed by measurements of sphericity, size, and fragment bed porosity of the fragmented material. After the experimental data were obtained, the influence of coolant properties on the fragmentation behavior was investigated and verified using Rayleigh-Taylor instability, Weber number theory, Kelvin-Helmholtz instability, and Froude number theory.
