铀棒栅实验装置是一个可变更堆芯结构的零功率反应堆,其突出特点是可以分别装载铅并以石墨作为反射层,或者装载水并以水作为反射层。该装置的控制保护系统要针对两种情况,完成特定的控制保护功能。铀棒栅实验装置控制保护系统包括:核测仪表、控制系统、保护系统、供电系统、控制台和机柜等5部分。核测仪表覆盖了启动量程和功率量程两个阶段。控制系统实现对中子源、安全棒、调节棒、底反射层、计量泵、电磁阀等的控制。其中底反射层控制系统在堆芯装载铅的情况下投入运行,计量泵和电磁阀在堆芯装载水的情况下投入运行,二
The uranium rod grid experiment is a zero-power reactor with a variable core structure. It features lead-loaded graphite with graphite as the reflector or water and water as the reflector. The device’s control protection system for both cases, to complete a specific control protection. Uranium rod gate experimental device control and protection system includes: nuclear instrumentation, control systems, protection systems, power supply systems, console and cabinets and other five parts. Nuclear instrumentation covers the start-up range and power range of two stages. The control system realizes the control of neutron source, safety rod, adjusting rod, bottom reflecting layer, metering pump, solenoid valve and so on. The bottom reflector control system is put into operation when the core is loaded with lead. The metering pump and the solenoid valve are put into operation when the core is loaded with water.
