Abstract

The plasma facing components (PFCs) are an important part of Steady State Superconducting Tokamak (SST-1) design. PFC of SST-1 consists of divertors, passive stabilizers, baffles and limiters are designed to be compatible for steady state operation. The main consideration in the design of the PFC is the steady state heat removal of up to 1 MW/m/sup 2/. During steady-state operation, the average heat loads on divertor and passive stabilizers are expected to be 0.6 and 0.25 MW/m/sup 2/ respectively. The PFC has been design to withstand the peak heat fluxes and also without significant erosion such that frequent replacement is not necessary. Design considerations included 2-D steady state and transient tile temperature distribution and resulting thermal loads in PFC during cooling. Coolant parameters necessary to maintain optimum thermal-hydraulic design, tile surface temperature, and tile fitting mechanism. A 2-D finite difference code has been developed to study of flow behavior and thermal response of PFC during cooling.

SST-1型托卡马克水冷PFC的研究与热工设计

面向等离子体元件是稳态超导托卡马克(SST-1)设计的重要组成部分。SST-1的PFC由分流器、被动稳定器、挡板和限制器组成，旨在与稳态操作兼容。PFC设计的主要考虑因素是高达1 MW/m/sup / 2/的稳态散热。在稳态运行期间，转向器和被动稳定器的平均热负荷预计分别为0.6和0.25 MW/m/sup /。PFC的设计可以承受峰值热通量，也没有明显的侵蚀，因此不需要频繁更换。设计考虑包括二维稳态和瞬态瓷砖温度分布以及PFC在冷却过程中产生的热负荷。冷却剂参数必须保持最佳的热液压设计，瓷砖表面温度和瓷砖安装机制。开发了一种二维有限差分程序来研究PFC在冷却过程中的流动特性和热响应。

期刊介绍： 19th-Century Music covers all aspects of Western art music between the mid-eighteenth and mid-twentieth centuries. We welcome--in no particular order--considerations of composers and compositions, styles, performance, historical watersheds, cultural formations, critical methods, musical institutions, ideas, and topics not named on this list. Our aim is to publish contributions to ongoing conversations at the leading edge of musical and multidisciplinary scholarship.
