Abstract

Abstract:

With the development of HCCB-DEMO blanket technology, an updated conceptual design of helium cooled blanket with ceramic breeder was proposed. Based on 3D FEM software ANSYS CFX，thermal-hydraulic analysis including first wall model, breeder unit model, stiffen grid model and integration model for HCCB blanket is presented in this paper. The results demonstrate that the maximum temperature of each material is in design limits; inlet/outlet temperature of coolant is 300/500°C under the independent analysis of sub-components, which indicate that the design requirements are satisfied. Comparing with three independent analysis models, the integration results showed that the thermal interaction between first wall and Be pebble bed have important influence; the maximum temperature of Be pebble bed exceeded the design limits. A series of optimization design for HCCB blanket focused on these problems would be the next step.

摘要：

根据这几年HCCB-DEMO包层技术的发展，对原氦冷固态氚增殖包层进行相应设计改进。利用三维有限元软件CFX对该改进设计进行了热工水力学计算及分析。分析模型包括：第一壁，增殖单元，筋板以及三者集成模型。结果表明：各子部件在单独分析的情况下，材料最高温度低于设计要求限值；冷却剂进出口温度为300/500°C，满足设计需求。同时对比分析了集成计算及单独计算的结果，得出第一壁与铍球床之间的相互热作用较大，铍球床材料最大温度会高于设计限值。针对经集成计算后发现的问题，未来将对氦冷固态包层的设计进行进一步的优化。
