Thermo-Physical Property Database of Fusion Materials and Thermo-Hydraulic Database of Breeder Blankets for CFETR

Abstract

The Chinese Fusion Engineering Test Reactor (CFETR) is a fusion engineering reactor independently designed and developed by China, and the design of the blanket is one of the key points during the design of CFETR. The configurations of CFETR, the detailed designs of the three types of blankets and typical blanket module, and the coolant flowing schemes in blanket module are introduced in paper. Besides, the work about Thermo-physical Property Database of Fusion Material and Thermo-hydraulic Database of Models established for the three types of blankets is presented. The fusion material involves Plasma Facing Materials (PFM), structural materials, coolant and breeding materials, and the peak temperature and the peak pressure in both steady-state and transient conditions are covered for property of materials. The thermo-hydraulic database includes the heat transfer models, the pressure drop models, and some special models for the fluid flow in blanket. In addition, the tests and verification for the database are performed, and the shortages and deficiencies of current database are analyzed.
