摘要

在熔盐堆燃料干法处理流程中，处理设备面临着严重的材质腐蚀问题。熔盐冷冻壁技术被视为保护相关设备耐受化学腐蚀的有效方法，而冷冻壁厚度的稳定控制是干法处理流程应用冷冻壁技术实现处理工艺目的的关键。基于自行研制的冷冻壁实验装置，模拟了干法处理中熔盐冷冻壁的应用工况，考察了导热油进口温度、熔盐初始温度、加热器功率、冷冻壁初始厚度对冷冻壁厚度变化的影响，得到了各个因素的影响规律，并总结了最佳的应用工艺条件。利用热流量的变化分析了冷冻壁厚度变化的原因：热流量越大，冷冻壁厚度减小量越大，达到平衡时，热流量越大，冷冻壁平衡厚度越小。通过实验数据拟合得到了线热流密度与冷冻壁平衡厚度的关系式，平均相对误差11.2%。

Abstract

Background:

During dry reprocessing of spent nuclear fuel in the molten salt reactor

the processing equipment is confronted with serious material corrosion problems. The molten salt frozen-wall technique has been proposed as an effective method to protect the equipment from chemical corrosion whilst stability of frozen wall thickness is the key to success in the application of frozen wall technique for dry reprocessing.

Purpose:

This paper aims to study the influence of key factors in the application of molten salt frozen wall.

Methods:

Based on the homemade experimental apparatus of frozen wall

the application of molten salt frozen wall during dry reprocessing was simulated. The influences of inlet temperature of oil

initial temperature of molten salt

heater power and initial thickness of frozen wall on the change of frozen wall in the process were analyzed

as well as the reasons behind the change of the thickness of frozen wall

via

the change of the heat flux.

Results:

The influence laws of main factors are obtained

and the optimum condition for use is obtained. Experimental data fitting results show the relationship between the heat flux of the unit length and the thickness of the frozen wall

and the average relative error rate is 11.2%.

Conclusion:

The greater heat flux is

the more frozen wall disappears. When equilibrium is reached

the greater the heat flux is

the smaller thickness of the frozen wall will be.
