實習題目：

對鉻涂層鋯包殼材料共晶反應機理的研究

The eutectic reaction in Chrome-coated Zircon alloy cladding

 

實習內容：

鉻涂層鋯合金包殼中鉻-鋯共晶反應對包殼的高溫氧化及其韌脆特性影響顯著，因此本實驗旨在研究反應堆中燃料棒的鋯包殼材料與含鉻涂層間的共晶反應機理，利用高溫反應爐探究反應溫度，接觸面壓強、反應物組分等不同因素對于鉻鋯共晶反應速率的影響。在得出實驗數據后，利用移動粒子半隱式方法（MPS）對不同實驗參數下的鉻鋯共晶反應過程進行數值模擬，驗證MPS方法對于鉻鋯共晶反應模擬的適用性并嘗試建立鉻鋯共晶反應模型。

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.

實習題目：

鉛冷快堆嚴重事故下FCI特性研究

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

 

實習內容：

本實驗研究的對象為第四代反應堆中的鉛冷快堆在發生嚴重堆芯解體事故(CDA)之后，熔融燃料和其他堆芯熔融物注入冷卻劑后發生的碎裂行為。

本實驗著重關注冷卻劑物性參數對熔融物碎化行為的研究。使用高溫加熱設備等實驗儀器以調整實驗參數，隨后對碎化物進行球形度、尺寸、碎片床孔隙率的測量。在得出實驗數據后，使用Rayleigh-Taylor不穩定性、Weber數理論、Kelvin-Helmholtz不穩定性、Froude數理論等方法，探究與驗證冷卻劑物性對碎化行為的影響。

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.
