中国先进研究堆(CARR)冷中子源堆内装置主要包括冷包及热虹吸回路装置、真空容器。冷包及热虹吸回路装置是冷中子源系统的关键设备之一,它将被包容在位于堆芯垂直实验孔道的真空容器内。冷包及热虹吸回路装置由法国Cryogenic Diffusion(CD)公司负责加工,由于特殊的结构特点和安全要求,冷包及热虹吸回路装置均采用双层壁结构。冷包及热虹吸回路内侧(氘侧)充慢化剂液氘,两层壁之间即冷包及热虹吸回路的
China Advanced Research Reactor (CARR) cold neutron source reactor devices include cold packs and thermal siphon circuit devices, vacuum containers. Cold packs and thermosyphon loops are one of the key devices in a cold neutron source system and will be contained within a vacuum vessel located in the vertical core of the reactor core. Cold packs and thermosyphon loops are processed by the French Cryogenic Diffusion (CD) company. Due to the special structural and safety requirements, both the cold packs and the thermosiphon loops are double walled. Cold package and thermal siphon loop inside (deuterium side) moderator liquid deuterium, between the two walls that cold pack and thermosyphon circuit
