根据拟开展ADS散裂靶与反应堆的耦合特性研究的需求和核安全法规对临界装置的设计安全规定,开展铀棒栅临界实验装置(以下简称实验装置)的结构设计与建造。此实验装置坐落在反应堆物理研究室的北大厅内,采用一套控制保护系统,具备水冷和铅冷的两种堆芯功能。根据核临界安全规范、试验要求以及理论计算结果而完成实验装置的设计、建造。考虑到堆厅的尺寸与位置,把水冷堆芯和铅冷堆芯分开布置。
The design and construction of the uranium rod gate critical experimental device (hereinafter referred to as the experimental device) is carried out according to the requirements of the research on the coupling characteristics of the proposed ADS spallation target and the reactor and the design safety requirements of the nuclear safety regulations for the critical device. Located in the North Hall of the Reactor Physics Laboratory, this experimental setup uses a control and protection system with two core functions of water cooling and lead cooling. According to nuclear criticality safety norms, test requirements and theoretical calculations to complete the experimental device design, construction. Taking into account the size and location of the hall, the water-cooled core and the lead-cooled reactor core are arranged separately.
