Design of Core Vessel and Core Structure in China Advanced Research Reactor

The core vessel and core structure of China Advanced Research Reactor (CARR) are one of the key components. Through sufficient investigation and well design, the technical problems of the anti-unlock design of threaded joints, the integer assemblage design of filler and grid assembly, the upper and lower support design of control rod guide tube, seal constructers design and so on were solved. Now, the core vessel and core structure were well set, which fulfill the anticipated design requirement through several design validatation experiments.
