A Ray-Tracing Analysis of ICRH in Tokamaks

Power deposition profiles generated by Ion Cyclotron Resonance Heating （ICRH） in non-circular tokamaks are studied using a ray-tracing technique. The simulation results for the Experimental Advanced Superconductor Tokamak （EAST） D-shaped plasma are presented. It is indicated that the spatial distributions of plasma parameters （plasma density, species temperature, minority ion concentration, etc.） have an significant influence on the power deposition profiles. The findings may be highly useful to the planned plasma heating and experiments in EAST.     

井下伴热电缆导体集肤效应的有限元法分析

运用有限元法, 对交频井下伴热电缆导体内部的集肤效应现象进行了数值模拟和分析,比较直观地得出交频电缆中电流密度的分布特性, 以及交流电的不同频率对导体集肤深度的影响。在集肤效应作用下, 电缆导体内部的有效过流面积减小, 交流阻抗显著加大, 其发热量也很大,井下电缆伴热加热技术就是利用这一原理来加热原油的。通过数值模拟, 可以定量地说明电参数对加热效果的影响, 为稠油井井下电缆伴热技术中优化加热参数提供指导。     

The appropriateness of the systematic framework to develop diagnosis procedures of nuclear power plants—an experimental verification

It has been well recognized that a diagnosis procedure that allows operators to successfully identify the nature of an on-going event is inevitable for an effective and appropriate recovery. Unfortunately, studies for a framework that can suggest a unified and consistent process in constructing a serviceable diagnosis procedure seem to be scant. Thus, Park et al. have suggested a systematic framework that can be used to construct a useful diagnosis procedure. In addition, the diagnosis procedure that is currently in use at the reference nuclear power plant (NPP) is reformed in order to demonstrate the appropriateness of the suggested framework. However, the necessity of a well-designed experiment is proposed to confirm the appropriateness of the suggested framework.In this regard, in this study, an experiment is conducted using a full-scope simulator of the reference NPP. From the experiment, two sets of operators' diagnosis performance data are collected, and then they are compared to investigate the change of an operator's diagnosis performance with respect to two types of diagnosis procedures.As a result, it is shown that an operator's diagnosis performance is improved when the revised diagnosis procedure is used. Therefore, it is reasonable to conclude that the suggested framework is useful in constructing an effective diagnosis procedure.
