Abstract

The experimental facility VULCAN was setup to study the fuel-coolant interaction (FCI) phenomena in a postulated severe accident of light water reactors. The heating system is important for the facility to prepare molten material in a crucible. This article is concerned with the design of the heating system, which applies electromagnetic induction heating method. The COMSOL code was employed to simulate the induction heating characteristics of a graphite crucible under different current and frequency of the work coil (inductor). Given a frequency, the relationship between the crucible’s average temperature and the inductor’s current is obtained, which is instrumental to select the power supply of the induction heating system. Meanwhile, the skin effect of induction heating is analyzed to guide the choice of frequency and inductor of the heating system. According to the simulation results, the induction heating system of frequency 47 kHz is suitable for the experiment, with a good agreement in temperature between the measured and the predicted.

VULCAN装置感应加热系统设计的COMSOL仿真

为研究轻水堆严重事故中燃料-冷却剂相互作用(FCI)现象，建立了VULCAN实验装置。加热系统对坩埚中熔融材料的制备至关重要。本文研究的是采用电磁感应加热方式的加热系统设计。采用COMSOL软件模拟了石墨坩埚在不同电流和工作线圈(电感)频率下的感应加热特性。在给定频率的情况下，得到了坩埚平均温度与电感电流的关系，为感应加热系统的电源选择提供了依据。同时，对感应加热的集肤效应进行了分析，以指导加热系统频率和电感的选择。仿真结果表明，采用频率为47 kHz的感应加热系统进行实验比较合适，测得的温度与预测的温度吻合较好。
