EAST托卡马克装置冷屏的真空要求与受热分析

THE ANALYZE OF VACUUM AND HEAT LOAD FOR TS OF EAST TOKAMAK

摘要: 冷屏是EAST超导托卡马克核聚变实验装置的重要部件之一。对冷屏系统的氦泄漏漏率做了计算,介绍了其检漏实践;采取有限元法对内冷屏的受热状况进行了计算分析,以验证内冷屏氦冷却管道设计方案的可靠性。

Abstract: The thermal shield（TS） is a main part of EAST superconducting Tokamak.The helium leakage from TS is estimated and the leak detecting of TS is described.The heat load to the vacuum vessel thermal shield（VVTS） is analyzed by FLUENT finite element software in order to demonstrate that the design of cooling tubes is reliable.
