AI总结:

本研究通过模拟托卡马克热负荷对钨材料的影响,探讨了瞬态热负荷对等离子体接触材料的破坏作用及严重性。

摘要:

核聚变装置不断面临来自等离子体接触材料损坏的故障威胁,因为这些材料受到热热负荷的影响。在大型托卡马克中,一些瞬态事件中的频繁热负荷一直令研究人员担忧。在ITER中,估计在边缘局域模中,热负荷为GW/m2,会对等离子体接触组件造成影响,此外,托卡马克稳态负载约为20 MW/m2。此外,由于ITER的非正常操作,如垂直位移事件或失稳,还会出现其他瞬态热负荷,分别达到数百MW/m2和数十GW/m2的量级。这些负荷足以导致等离子体接触材料的严重损坏。在本研究中,托卡马克热负荷下钨材料的破坏进行了模拟,并展示了结果。

英文摘要:

Nuclear fusion devices are constantly under the threat of malfunctions coming from the damages of plasma-facing materials due to being affected by thermal heat loads. The frequent heat loads during some transient events in large-scale Tokamaks have always been a great concern for researchers. In ITER, the heat load of GW/m2 is estimated to impose plasma-facing components during edge localized modes, beside the Tokamak steady state load which is about 20 MW/m2. Moreover, there are also other transient thermal loads occurring due to off-normal operation of ITER such as vertical displacement events or disruptions, at the orders of hundreds of MW/m2 and tens of GW/m2, respectively. These loads are great enough to result in severe damages of plasma-facing materials. In this study, the facture of tungsten material under the heat loads of Tokamaks is simulated and the results are presented.
